Guide to Anterior Cruciate Ligament (ACL) Tear

An anterior cruciate ligament (ACL) tear is an injury to the knee commonly affecting athletes, such as soccer players, basketball players, skiers, and gymnasts. Nonathletes can also experience an ACL tear due to injury or accident. Approximately 200,000 ACL injuries are diagnosed in the United States each year. It is estimated that there are 95,000 ruptures of the ACL and 100,000 ACL reconstructions performed per year in the United States. Approximately 70% of ACL tears in sports are the result of noncontact injuries, and 30% are the result of direct contact (player-to-player, player-to-object). Women are more likely than men to experience an ACL tear. Physical therapists are trained to help individuals with ACL tears reduce pain and swelling, regain strength and movement, and return to desired activities.

What is an ACL Tear?

The ACL is one of the major bands of tissue (ligaments) connecting the thigh bone (femur) to the shin bone (tibia) at the knee joint. It can tear if you:

  • Twist your knee while keeping your foot planted on the ground.

  • Stop suddenly while running.

  • Suddenly shift your weight from one leg to the other.

  • Jump and land on an extended (straightened) knee.

  • Stretch the knee farther than its usual range of movement.

  • Experience a direct hit to the knee.

How Does it Feel?

When you tear the ACL, you may feel a sharp, intense pain or hear a loud "pop" or snap. You might not be able to walk on the injured leg because you can’t support your weight through your knee joint. Usually, the knee will swell immediately (within minutes to a few hours), and you might feel that your knee "gives way" when you walk or put weight on it.

How Is It Diagnosed?

Immediately following an injury, you may be examined by a physical therapist, athletic trainer, or orthopedic surgeon. If you see your physical therapist first, your therapist will conduct a thorough evaluation that includes reviewing your health history. Your physical therapist will ask:

  • What you were doing when the injury occurred.

  • If you felt pain or heard a "pop" when the injury occurred.

  • If you experienced swelling around the knee in the first 2 to 3 hours following the injury.

  • If you felt your knee buckle or give out when you tried to get up from a chair, walk up or down stairs, or change direction while walking.

Your physical therapist may perform gentle "hands-on" tests to determine the likelihood that you have an ACL tear, and may use additional tests to assess possible damage to other parts of your knee.

An orthopedic surgeon may order further tests, including magnetic resonance imaging (MRI), to confirm the diagnosis and rule out other possible damage to the knee.

Surgery

Most people who sustain an ACL tear will undergo surgery to repair the tear; however, some people may avoid surgery by modifying their physical activity to relieve stress on the knee. A select group can actually return to vigorous physical activity following rehabilitation without having surgery.

Your physical therapist, together with your surgeon, can help you determine if nonoperative treatment (rehabilitation without surgery) is a reasonable option for you. If you elect to have surgery, your physical therapist will help you prepare both for surgery and to recover your strength and movement following surgery.

How Can a Physical Therapist Help?

Once an ACL tear has been diagnosed, you will work with your surgeon and physical therapist to decide if you should have surgery, or if you can recover without surgery. If you don’t have surgery, your physical therapist will work with you to restore your muscle strength, agility, and balance, so you can return to your regular activities. Your physical therapist may teach you ways to modify your physical activity in order to put less stress on your knee. If you decide to have surgery your physical therapist can help you before and after the procedure.

Treatment Without Surgery

Current research has identified a specific group of patients (called "copers") who have the potential for healing without surgery following an ACL tear. These patients have injured only the ACL, and have experienced no episodes of the knee "giving out" following the initial injury. If you fall into this category, based on the specific tests your physical therapist will conduct, your therapist will design an individualized physical therapy treatment program for you. It may include treatments such as gentle electrical stimulation applied to the quadriceps muscle, muscle strengthening, and balance training.

Treatment Before Surgery

If your orthopedic surgeon determines that surgery is necessary, your physical therapist can work with you before and after your surgery. Some surgeons refer their patients to a physical therapist for a short course of rehabilitation before surgery. Your physical therapist will help you decrease your swelling, increase the range of movement of your knee, and strengthen your thigh muscles (quadriceps).

Treatment After Surgery

Your orthopedic surgeon will provide postsurgery instructions to your physical therapist, who will design an individualized treatment program based on your specific needs and goals. Your treatment program may include:

Bearing weight. Following surgery, you will use crutches to walk. The amount of weight you are allowed to put on your leg and how long you use the crutches will depend on the type of reconstructive surgery you have received. Your physical therapist will design a treatment program to meet your needs and gently guide you toward full weight bearing.

Icing and compression. Immediately following surgery, your physical therapist will control your swelling with a cold application, such as an ice sleeve, that fits around your knee and compresses it.

Bracing. Some surgeons will give you a brace to limit your knee movement (range of motion) following surgery. Your physical therapist will fit you with the brace and teach you how to use it safely. Some athletes will be fitted for braces as they recover and begin to return to their sports activities.

Movement exercises. During your first week following surgery, your physical therapist will help you begin to regain motion in the knee area, and teach you gentle exercises you can do at home. The focus will be on regaining full movement of your knee. The early exercises help with increasing blood flow, which also helps reduce swelling.

Electrical stimulation. Your physical therapist may use electrical stimulation to help restore your thigh muscle strength, and help you achieve those last few degrees of knee motion.

Strengthening exercises. In the first 4 weeks after surgery, your physical therapist will help you increase your ability to put weight on your knee, using a combination of weight-bearing and non-weight-bearing exercises. The exercises will focus on your thigh muscles (quadriceps and hamstrings) and might be limited to a specific range of motion to protect the new ACL. During subsequent weeks, your physical therapist may increase the intensity of your exercises and add balance exercises to your program.

Balance exercises. Your physical therapist will guide you through exercises on varied surfaces to help restore your balance. Initially, the exercises will help you gently shift your weight on to the surgery leg. These activities will progress to standing on the surgery leg, while on firm and unsteady surfaces to challenge your balance.

Return to sport or activities. As athletes regain strength and balance, they may begin running, jumping, hopping, and other exercises specific to their individual sport. This phase varies greatly from person-to-person. Physical therapists design return-to-sport treatment programs to fit individual needs and goals.

Can this Injury or Condition be Prevented?

Much of the research on ACL tears has been conducted with female collegiate athletes, because women are 4 to 6 times more likely to experience the injury. Preventive physical therapy programs have proven to lower ACL injury rates by 41% for female soccer players. Researchers have made the following recommendations for a preventive exercise program:

  • The program should be designed to improve balance, strength, and sports performance. Strengthening your core (abdominal) muscles is key to preventing injury, in addition to strengthening your thigh and leg muscles.

  • Exercises should be performed 2 or 3 times per week and should include sport-specific exercises.

  • The program should last no fewer than 6 weeks.

Although most exercise studies have been conducted with female athletes, the findings may benefit male athletes as well.

Real Life Experiences

Anita is a 20-year-old student at a local university, and a star basketball player. Her team is off to a great start this year; the buzz around campus is that this could be a dream team!

But tonight, when Anita goes up for a rebound and lands off-balance, she hears a "pop" in her left knee and feels a sharp pain. When she tries to walk, she realizes that she can't put weight on her left leg. She's led back to the training room, where the school physical therapist conducts an evaluation. The test results indicate injury, and the physical therapist notices an increase in swelling around the knee just 30 minutes after the incident. She suspects an ACL tear, and refers Anita to an orthopedic surgeon. The next day, the surgeon confirms the diagnosis of an ACL tear, and tells Anita that her injury requires surgery.

After a short course of treatment by her new local physical therapist, including pain and swelling management, manual (hands-on) therapy, and knee range-of-motion and strengthening exercises, Anita has surgery the following month. Her surgeon schedules her to receive physical therapy 3 days after her surgery. She is advised to ice and elevate the knee several times per day.

Three days after surgery, Anita returns to her local physical therapist to begin her rehabilitation. He shows her how to use her crutches properly to gently begin to put weight on the operative knee. He guides her to contract/tighten the quadriceps muscle, and gently performs manual (hands-on) stretches for her to straighten the knee.

Over the next few weeks, Anita is able to gradually stop using her crutches, and begins to put her full weight on her left leg. She can also fully straighten her knee and tighten her quadriceps muscle without help from her physical therapist. She learns exercises she can safely perform at home.

After 5 weeks, Anita is able to walk normally, fully extending her knee with no pain or feelings of instability. During the next 2 months, she and her physical therapist work on her strength and balance. She finds the hardest exercises are the balance exercises, which require her to balance on a piece of foam or a rocker board while throwing a ball.

About 4 months after surgery, Anita's physical therapist designs a gentle jogging program for her. At 5 months, he allows her to begin a running program. He also adds exercises during Anita's physical therapy sessions that mimic basketball activities such as rebounding or taking a jump shot. During these activities, Anita’s physical therapist teaches her proper landing techniques to lessen the chance of reinjuring her knee when she returns to play.

After 8 months, Anita is allowed to practice with her team. They are thrilled and excited to see their star player is back. Last year was a good year for the team, but it ended in the first round of the playoffs.

Anita and her team begin a new year of full competition 11 months after her surgery. With Anita back in top form, they make the playoffs, blast through to the finals – and bring home the trophy!

This story was based on a real-life case. Your case may be different. Your physical therapist will tailor a treatment program to your specific case.

What Kind of Physical Therapist Do I Need?

Although all physical therapists are prepared through education and experience to treat a variety of conditions or injuries, you may want to consider:

  • A physical therapist who is experienced in treating people with orthopedic (musculoskeletal) problems.

  • A physical therapist who is a board-certified clinical specialist or who has completed a residency or fellowship in orthopedic physical therapy and has advanced knowledge, experience, and skills that may apply to your condition.

You can find physical therapists with these and other credentials by using Find a PT, the online tool built by the American Physical Therapy Association to help you search for physical therapists with specific clinical expertise in your geographic area.

General tips when you're looking for a physical therapist:

  • Get recommendations from family and friends or from other health care providers.

  • When you contact a physical therapy clinic for an appointment, ask about the physical therapist's experience in helping people with ACL tears.

During your first visit with the physical therapist, be prepared to describe your symptoms in as much detail as possible, and say what makes your symptoms worse.

Pes Anserine Bursitis

Pes anserine bursitis is a condition that produces pain on the inside of the knee and lower leg. It occurs most commonly in young people involved in sports (eg, running or swimming the breaststroke), middle-aged women who are overweight, and people aged 50 to 80 years who have osteoarthritis of the knee. Up to 75% of people who have osteoarthritis of the knee have symptoms of pes anserine bursitis. The condition is also commonly associated with type 2 diabetes; 24% to 34% of patients with type 2 diabetes who report knee pain are found to have pes anserine bursitis. However, in some cases no direct cause can be identified. Physical therapists treat people with pes anserine bursitis to reduce pain, swelling, stiffness, and weakness, as well as identify and treat the underlying cause of the condition.

What is Pes Anserine Bursitis?

The pes anserine bursa is a small, fluid-filled sac located 2 to 3 inches below the knee joint on the inside of the lower leg. It lies beneath 3 tendons that attach to muscles of the thigh, and prevents the tendons from rubbing on the shinbone (tibia). The term “bursitis” describes a condition where the bursa has become irritated and inflamed. This condition is usually painful and associated with some swelling in the affected area. Certain positions, motions, or disease processes can cause increased friction or stress on the bursa, leading to the development of bursitis.

Pes anserine bursitis can be caused by:

  • Repetitive activities, like squatting, stair climbing, and other work or household activities that are often repeated

  • Incorrect sports training techniques, such as a lack of stretching, sudden increases in run distances, or too much uphill running

  • Obesity

  • Osteoarthritis of the knee

  • Valgus positioning of the knee (ie, a “knock-knee” position where the knees angle inward)

  • Turning the leg sharply with the foot planted on the ground

  • Injury, such as a direct hit to the leg

  • Tight hamstring (back of the thigh) muscles

  • A tear in the cartilage of the knee

  • Flat feet

How Does it Feel?

With pes anserine bursitis, you may experience:

  • Pain and swelling on the inside of the lower leg, 2 to 3 inches below the knee joint; this pain may also extend to the front of the knee and down the lower leg

  • Pain when touching the inside of the lower leg, 2 to 3 inches below the knee joint

  • Pain when bending or straightening the knee

  • Pain or difficulty walking, sitting down, rising from a chair, or climbing stairs

How Is It Diagnosed?

Your physical therapist will conduct a thorough examination that includes taking your health history as well as asking you detailed questions about your injury, such as:

  • How and when did you notice the pain?

  • Did you feel pain or hear a "pop" when you injured your leg?

  • Did you turn your leg with your foot planted on the ground?

  • Did you change direction quickly while running?

  • Did you receive a direct hit to the leg while your foot was planted on the ground?

  • Did you see swelling around the knee in the first 2 to 3 hours following the injury?

  • Does your knee feel like it is buckling or “giving way” when you try to use it?

Your physical therapist also will perform special tests to help determine the likelihood that you have pes anserine bursitis. Your therapist may:

  • Gently press on the inner side of your knee to see if it is painful to the touch

  • Assess the range of motion you have at the knee and hip, as well as the strength of some of the muscles at these joints

  • Observe how you are walking, squatting, and performing other functional and sports-specific tasks as appropriate

To provide a definitive diagnosis, your physical therapist may collaborate with an orthopedic physician or other health care provider, who may order further tests, such as an x-ray, to confirm the diagnosis and to rule out other damage to the knee.

How Can a Physical Therapist Help?

Your physical therapist will work with you to design a specific treatment program that will speed your recovery, including exercises and treatments that you can do at home. Physical therapy will help you return to your normal lifestyle and activities.

The First 24 to 48 Hours

If you see a physical therapist within 24 to 48 hours of your injury, your therapist may advise you to:

  • Rest the area by avoiding walking or any activity that causes pain.

  • Apply ice packs to the area for 15 to 20 minutes every 2 hours.

  • Consult with a physician for further services, such as medication or diagnostic tests.

Individualized Treatment

Depending on your condition and goals, your individualized rehabilitation plan may include treatments to:

Reduce pain and swelling. Your physical therapist may use different types of treatments to control and reduce your pain and swelling, including ice, heat, ultrasound, electrical stimulation, taping, exercises, and hands-on therapy, such as massage.

Improve motion. Your physical therapist will choose specific activities and treatments to help restore normal movement in the knee and leg. These might begin with "passive" motions that the physical therapist performs for you to gently move your leg and knee joint, and then progress to active exercises that you do yourself.

Improve flexibility. Pes anserine bursitis is often related to tight hamstring (back of the thigh) muscles. Your physical therapist will determine if your hamstring muscles or any other leg muscles are tight, and teach you how to stretch them.

Improve strength. Certain exercises will aid healing at each stage of recovery. Your physical therapist will choose and teach you the correct exercises and equipment to steadily restore your muscle strength and power. These may include using cuff weights, stretch bands, weight-lifting equipment, and cardio-exercise equipment, such as treadmills or stationary bicycles.

Improve balance. Regaining your sense of balance is important after an injury. Your physical therapist may teach you exercises to improve your balance skills.

Speed recovery time. Your physical therapist is trained and experienced in choosing the best treatments and exercises to help you heal, return to a normal lifestyle, and reach your goals faster than you are likely to do on your own.

Return to activities. Initially, your physical therapist may recommend that you reduce or eliminate activities that aggravate your condition for a period of time. Your physical therapist will discuss your goals with you and set up a treatment program to help you meet them in the safest, fastest, and most effective way possible. You may learn specific exercises, work retraining activities, and sport-specific techniques and drills to help you achieve your own unique goals.

Other Treatment Options

Studies have shown that some patients who do not respond to conservative treatment, such as physical therapy, may benefit from medical therapy. Your physical therapist may recommend that you discuss other treatment options with your physician, including surgery. Although surgery is rarely prescribed for pes anserine bursitis, it sometimes is needed. If surgery is required for your condition, you will follow a recovery program over several weeks guided by your physical therapist. Your physical therapist will help you minimize pain, regain motion and strength, and return to normal activities in the safest and speediest manner possible.

Can this Injury or Condition be Prevented?

Your physical therapist can recommend a home-exercise program to strengthen and stretch the muscles around your knees, upper legs, and abdomen to help prevent the onset or recurrence of pes anserine bursitis. These may include strength and flexibility exercises for the legs, knees, and core muscles.

To help prevent a recurrence of the injury, or prevent its onset if you seek guidance before injury, your physical therapist may advise you to:

  • Learn correct knee positioning when participating in athletic activities.

  • Follow a consistent flexibility and strength exercise program, especially for the leg and hip muscles, to maintain good physical conditioning.

  • Practice balance and agility exercises and drills.

  • Always warm up before starting a sport or heavy physical activity.

  • Avoid sudden increases in running mileage or uphill running.

  • Wear shoes that are in good condition and fit well.

  • Maintain a healthy weight.

  • Treat and manage diabetes very closely.

  • Wear orthotics to reduce flat feet and valgus (knock-knee) positioning of the lower extremities.

  • Wear a knee brace to support the knee and reduce strain on the inside of the joint.

Real Life Experiences

Martha is a 40-year-old secretary who has become obese. Her goal is to lose 100 pounds with diet and exercise. To reach that goal, Martha recently joined a gym, and decided to try the latest craze—a Zumba class. Martha enjoyed the first week of classes, but when leaving the gym after the fourth class, she felt a sharp pain in the inner, lower side of her right knee. It got worse when she bent and straightened her knee and when she walked upstairs to go to bed that night. The next day, the pain was still there, making it hard for her to get to work. She contacted her physical therapist.

Martha’s physical therapist performed special tests on the tendons and muscles around the knee, and found that her hamstring (back of the thigh) muscles were extremely tight and her quadriceps (front of the thigh) muscles were weak. Martha’s knee was tender to the touch, and mildly swollen 2 to 3 inches below the knee joint on the inner side of the leg, where the pes anserine bursa is located.

Martha's physical therapist explained that her pes anserine bursa was irritated and swollen. He applied ice and electrical stimulation to the area for 20 minutes. He also applied some tape to gently support Martha's hamstring muscles and alleviate the swelling and pain. He showed her how to stretch her hamstring muscles at home, and how to apply ice every few hours. He recommended that she not attend her Zumba class until her symptoms cleared up.

When Martha returned for her next visit, her physical therapist taught her some exercises to improve the strength of the muscles of her legs and “core,” and to improve her balance. Martha and her physical therapist worked together consistently over the next few weeks. Her treatment program, both in the clinic and at home, as well as her return to activity, were carefully adjusted to help ensure her safe and effective recovery.

Martha received physical therapy treatments for 6 weeks, at which time she felt almost 100% pain free—and much stronger. Martha returned to the gym to perform the exercises and stretches she learned in physical therapy as well as a modified fitness program. By the fourth week, she was able to participate in half of the Zumba class and by the fifth week, to finish the full class.

Martha has continued to do the stretches and exercises she learned from her physical therapist, and is proud to report to her friends and family that she is now pain free—and losing weight!

What Kind of Physical Therapist Do I Need?

All physical therapists are prepared through education and experience to treat pes anserine bursitis. However, you may want to consider:

  • A physical therapist who is experienced in treating people with orthopedic injuries. Some physical therapists have a practice with an orthopedic focus.

  • A physical therapist who is a board-certified clinical specialist or who has completed a residency or fellowship in orthopedic or sports physical therapy. This physical therapist has advanced knowledge, experience, and skills that may apply to your condition.

You can find physical therapists who have these and other credentials by using Find a PT, the online tool built by the American Physical Therapy Association to help you search for physical therapists with specific clinical expertise in your geographic area.

Osteoporosis

What is Osteoporosis?

Osteoporosis is a bone disease characterized by low bone density (thickness of the bone), decreased bone strength, and a change in the bone structure, which can lead to an increased risk of fracture. The normal bone structure becomes thinned out and porous with poor nutrition, aging, or when osteoporosis develops, lessening the ability of the bone to withstand the typical forces that are applied in everyday living. Fractures from low bone density and osteoporosis can be serious, causing pain and affecting quality of life.

Bone is living tissue. Normally, one type of cell removes bone and another type of cell adds bone in a balanced, ongoing process. In osteoporosis, bones weaken when not enough new bone is formed and/or too much bone is lost. This imbalance commonly begins in women during the first 5 years of menopause. However, it can also occur in men and in children, often due to diseases that affect bone development, such as celiac disease, inflammatory bowel disease, rheumatoid arthritis, spina bifida, cystic fibrosis, or kidney disease. Some medicines, such as steroids, may increase the risk of developing osteoporosis. Athletes who are underweight during the time of peak bone development are also susceptible.

There are many factors that can cause a person to be at risk for developing osteoporosis. It is important to know your risks so that you can be diagnosed and proactive in your treatment.

Risk Factors for Osteoporosis

Noncontrollable risks

  • Female gender

  • Small frame

  • Advanced age

  • Hormone levels

  • Genetics

  • Predisposing medical conditions

Controllable risks

  • Cigarette smoking

  • Excessive alcohol intake

  • Inactive lifestyle

  • Excessive caffeine intake

  • Lack of weight-bearing exercise

  • Drugs (eg, steroids, heparin)

  • Poor health

  • Low weight

  • Calcium-poor diet

  • Low vitamin D levels

 


How Does it Feel?

Osteoporosis is a disease that can be "silent." There may be no outward symptoms until a fracture occurs. If you are middle-aged or older, you may notice a loss of height or the appearance of a humpback. You may also begin to experience pain between your shoulder blades or above the crest of the pelvis.

People with low bone density may experience fractures in everyday situations that would not occur in persons with healthy bones, such as breaking a hip or a wrist with a fall from a standing height, breaking a rib when opening a window or when receiving a hug, or breaking an ankle after stepping off a curb. These are called fragility fractures and are a red flag for bone disease. Spinal compression fractures, particularly those in the upper back or thoracic spine (area between the neck and the lower back), are the most common fractures, followed by hip and wrist fractures.


How Is It Diagnosed?

If you are seeing a physical therapist for back pain or other rehabilitation issues, the therapist will review your medical, family, medication, exercise, dietary, and hormonal history, conduct a complete physical examination, and determine your risk factors for osteoporosis. The assessment may lead the physical therapist to recommend further testing.

Osteoporosis is best diagnosed through a quick and painless specialized X-ray called the DXA, which measures bone density. The results are reported using T-scores and Z-scores.

  • The T-score compares your score to that of healthy 30-year-old adults. If you have a T-score of -1 or less, you have a greater risk of having a fracture.

  • If the T-score is -2.5 or less you will receive the diagnosis of osteoporosis.

  • The Z-score compares your bone mineral density to those of the same sex, weight, and age. It is used for those whose bone mass has not yet peaked, premenopausal women, and men older than 50.

Other methods of measuring bone density include X-ray, ultrasound, and CT scan. 


How Can a Physical Therapist Help?

Your physical therapist can develop a specific program based on your individual needs to help improve your overall bone health, keep your bones healthy, and help you avoid fracture. Your physical therapist may teach you:

  • Specific exercises to build bone or decrease the amount of bone loss

  • Proper posture to protect your spine from fracture

  • Proper alignment during activities of daily living

  • How to improve your balance so as to reduce your risk of falling

  • How to adjust your environment to protect your bone health

Healthy bone is built and maintained through a healthy lifestyle. Your physical therapist will teach you specific exercises to meet your particular needs.

The exercise component for bone building or slowing bone loss is very specific and similar for all ages. Bone grows when it is sufficiently and properly stressed, just as muscle grows when challenged by more than usual weight. Two types of exercise are optimal for bone health: weight-bearing and resistance.

It is best for a physical therapist to provide your individual bone-building prescription to ensure that you are neither overexercising nor underexercising. Typically, exercises are performed 2 to 3 times a week as part of an overall fitness program.

Weight-bearing exercises

  • Dancing

  • Jogging (if your bone density is higher than -3.0)

  • Racquet sports

  • Heel drops

  • Stomping

Resistance exercises

  • Weight lifting in proper spine and lower-extremity alignment

  • Use of exercise bands

  • Gravity resistance (eg, push-ups, prone trunk extension with cushion to protect lowest ribs, single-leg heel raises, squats, lunges, sustained standing yoga poses in neutral spine position)

  • Exercises that reduce or stabilize kyphosis (hunchback)

  • Balance exercises

If you are diagnosed with osteoporosis or low bone density, your physical therapist will work with you to:

  • Build bone or lessen the amount of bone loss at areas most vulnerable to fracture through exercise—hip, spine, shoulder, arms.

  • Improve your dynamic balance to avoid falls.

  • Improve your posture.

  • Adjust your work and living environments to limit risk.

  • Help you avoid exercises and movements that may contribute to spinal fracture, including any type of sit-up or crunch, and excessive spinal or hip twisting.

Conservative treatment of a fracture includes bed rest and appropriate pain treatment. Your physical therapist will work with you to:

  • Decrease your pain through positioning and other pain-relieving modalities. Individualized physical therapist regimens can help reduce pain without the need for medications, such as opioids.

  • Provide appropriate external devices, such as bracing, to promote healing and improve posture.

  • Decrease your risk of a fall, strengthen your muscles, and improve your postural alignment.

  • Avoid exercises that involve too much forward or side bending or twisting.

  • Avoid water or endurance exercises, as they have been shown to negatively affect bone density.

If your pain lasts longer than 6 weeks following a spinal fracture, you can discuss surgical options, such as vertebroplasty or kyphoplasty, with your physical therapist, primary care physician, and surgeon.

Children and adolescents. Physical therapists can educate families and youth groups on proper exercise and posture, and about the need to move daily to build bone strength and prevent bone loss. Children with health issues such as spina bifida, diabetes, Crohn's disease, and cerebral palsy are at a greater risk for bone disease and can particularly benefit from the guidance of a physical therapist. Proper physical conditioning is crucial for children and adolescents: the majority of bone is built during adolescence and peaks by the third decade of life.

Middle-aged and older adults. As people age, they may begin to notice postural, balance, and strength changes. Physical therapists work with middle-aged and older adults to:

  • Develop individualized exercise programs to promote bone growth or lessen bone loss

  • Improve dynamic balance to avoid falls

  • Improve posture

  • Improve the strength of back muscles

  • Improve hip strength and mobility


Can this Injury or Condition be Prevented?

Osteoporosis can be prevented by building adequate bone density through childhood, adolescence, and early adulthood. Building strong bones requires an adequate intake of calcium and vitamin D, and regular exercise.

There are steps to take to improve bone health at any age. An active lifestyle that includes resistance and weight-bearing exercise is important to maintain healthy bone. It is also important to avoid habits that promote bone loss, such as smoking, excessive alcohol consumption, and an inadequate intake of calcium in your diet. Maintaining good body mechanics and posture also contribute to good bone health. We have no control over the genetic tendencies we have inherited, but we can choose to manage osteoporosis through proper medication, diet, and appropriate exercise.

As with any health issue, an overall healthy lifestyle is important for staying well.


Real Life Experiences

Anna is a 69-year-old retired legal secretary. She has enjoyed her early years of retirement, taking long walks in beautiful settings across the United States. Two years into her retirement, however, she began having knee pain during some of her walks, which gradually grew worse. Last year, she had a total knee replacement due to arthritis. She now walks with a cane because of chronic knee and ankle pain, and has experienced a loss of balance. She also has developed a rounded upper back, and low back pain. She seeks the help of a physical therapist.

Anna's physical therapist performs an assessment that includes a medical review for osteoporosis risk factors and for other health issues. He evaluates her range of motion and strength, testing her arms, legs, and trunk—especially her upper back. He tests the flexibility of her spine and her balance, her walking ability, and her risk of falling. Anna's walking style is uneven and she leans heavily on her cane. A DXA scan reveals that Anna has lost bone density in her spine and both hips. A vertebral fracture assessment X-ray shows that she has painless compression fractures of her spine. Her physical therapist diagnoses osteoporosis of the spine.

Anna first works with her physical therapist to improve her posture and knee function through flexibility and strengthening exercises, so she can walk more normally while working on her balance to lower her fall risk. She tells him her main goal is to be able to take walks in the park again.

Anna’s physical therapist teaches her safe trunk movement to avoid spinal fracture. Anna agrees to wear a dynamic trunk brace 2 hours a day to help make her posture more upright. She practices weight-bearing exercises with considerations for her arthritis, and learns resistive strengthening exercises for her spine and hip. Anna's physical therapist designs a gentle home-exercise program for her as well.

By her last visit, the flexibility and strength of Anna’s trunk and legs and her tolerance of physical activity have improved. The quality of her walking and dynamic balance are measurably improved, and her risk of falling has decreased. Anna feels much more confident about managing her condition.

Just this past week, Anna joined a therapeutic senior walking group that meets at the local botanic garden twice a week. She is thrilled to be enjoying gentle walks in nature again, and looks forward to coordinating other activities with her new group of friends!

This story was based on a real-life case. Your case may be different. Your physical therapist will tailor a treatment program to your specific case.


What Kind of Physical Therapist Do I Need?

All physical therapists are prepared through education and experience to treat those with osteoporosis. However, if you have a diagnosis of osteoporosis or low bone density, you may want to consider:

  • A physical therapist who is a board-certified clinical specialist or who completed a residency or fellowship in orthopedic physical therapy or geriatric physical therapy. This physical therapist has advanced knowledge, experience, and skills that may apply to your condition.

  • A physical therapist who specializes in the treatment of osteoporosis.

You can find physical therapists with these and other credentials by using Find a PT, the online tool by the American Physical Therapy Association that can help you search for physical therapists with specific clinical expertise in your geographic area.

General tips when you're looking for a physical therapist (or any other health care provider):

  • Get recommendations from family and friends or from other health care providers.

  • When you contact a physical therapy clinic for an appointment, ask about the physical therapists' experience in helping people who have osteoporosis.

Osteoarthritis of the Knee

Osteoarthritis of the knee (knee OA) is the inflammation and wearing away of the cartilage on the bones that form the knee joint (osteo=bone, arthro=joint, itis=inflammation). The diagnosis of knee OA is based on 2 primary findings: radiographic evidence of changes in bone health (through medical images such as X-ray and magnetic resonance imaging [MRI]), and an individual’s symptoms (how you feel). Approximately 14 million people in the United States have symptomatic knee OA. Although more common in older adults, 2 million of the 14 million people with symptomatic knee OA were younger than 45 when diagnosed, and more than half were younger than 65.

What is Osteoarthritis of Knee?

Knee osteoarthritis (knee OA) is a progressive disease caused by inflammation and degeneration of the knee joint that worsens over time. It affects the entire joint, including bone, cartilage, ligaments, and muscles. Its progression is influenced by age, body mass index (BMI), bone structure, genetics, muscular strength, and activity level. Knee OA also may develop as a secondary condition following a traumatic knee injury. Depending on the stage of the disease and whether there are associated injuries or conditions, knee OA can be managed with physical therapy. More severe or advanced cases may require surgery.


How Does it Feel?

Individuals who develop knee OA may experience a wide range of symptoms and limitations based on the progression of the disease. Pain occurs when the cartilage covering the bones of the knee joint wears down. Areas where the cartilage is worn down or damaged exposes the underlying bone. The exposure of the bone allows increased stress and compression to the cartilage, and at times bone-on-bone contact during movement, which can cause pain. Because the knee is a weight-bearing joint, your activity level, and the type and duration of your activities usually have a direct impact on your symptoms. Symptoms may be worse with weight-bearing activity, such as walking while carrying a heavy object.

Symptoms of knee OA may include:

  • Worsening pain during or following activity, particularly with walking, climbing, or descending stairs, or moving from a sitting to standing position

  • Pain or stiffness after sitting with the knee bent or straight for a prolonged period of time

  • A feeling of popping, cracking, or grinding when moving the knee

  • Swelling following activity

  • Tenderness to touch along the knee joint

Typically these symptoms do not occur suddenly or all at once, but instead develop gradually over time. Sometimes individuals do not recognize they have osteoarthritis because they cannot remember a specific time or injury that caused their symptoms. If you have had worsening knee pain for several months that is not responding to rest or a change in activity, it is best to seek the advice of a medical provider.


How Is It Diagnosed?

Knee OA is diagnosed by 2 primary processes. The first is based on your report of your symptoms and a clinical examination. Your physical therapist will ask you questions about your medical history and activity. The therapist will perform a physical exam to measure your knee's movement (range of motion), strength, mobility, and flexibility. You might also be asked to perform various movements to see if they increase or decrease the pain you are experiencing.

The second tool used to diagnose knee OA is diagnostic imaging. Your physical therapist may refer you to a physician, who will order X-rays of the knee in a variety of positions to check for damage to the bone and cartilage of your knee joint. If more severe joint damage is suspected, an MRI may be ordered to look more closely at the overall status of the joint and surrounding tissues. Blood tests also may be ordered to help rule out other conditions that can cause symptoms similar to knee OA.


How Can a Physical Therapist Help?

Once you have received a diagnosis of knee OA, your physical therapist will design an individualized treatment program specific to the exact nature of your condition and your goals. Your treatment program may include:

Range-of-motion exercises. Abnormal motion of the knee joint can lead to a worsening of OA symptoms when there is additional stress on the joint. Your physical therapist will assess your knee’s range of motion compared with expected normal motion and the motion of the knee on your uninvolved leg. Your range-of-motion exercises will focus on improving your ability to bend and straighten your knee, as well as improve your flexibility to allow for increased motion.

Muscle strengthening. Strengthening the muscles around your knee will be an essential part of your rehabilitation program. Individuals with knee OA who adhere to strengthening programs have been shown to have less pain and an improved overall quality of life. There are several factors that influence the health of a joint: the quality of the cartilage that lines the bones, the tissue within and around the joints, and the associated muscles. Due to the wear and tear on cartilage associated with knee OA, maintaining strength in the muscles near the joint is crucial to preserve joint health. For example, as the muscles along the front and back of your thigh (quadriceps and hamstrings) cross the knee joint, they help control the motion and forces that are applied to the bones.

Strengthening the hip and core muscles also can help balance the amount of force on the knee joint, particularly during walking or running. The “core” refers to the muscles of the abdomen, low back, and pelvis. A strong core will increase stability throughout your body as you move your arms and legs. Your physical therapist will assess these different muscle groups, compare the strength in each limb, and prescribe specific exercises to target your areas of weakness.

Manual therapy. Physical therapists are trained in manual (hands-on) therapy. Your physical therapist will gently move your muscles and joints to improve their motion, flexibility, and strength. These techniques can target areas that are difficult to treat on your own. The addition of manual therapy techniques to exercise plans has been shown to decrease pain and increase function in people with knee OA.

Bracing. Compressive sleeves placed around the knee may help reduce pain and swelling. Devices such as realignment and off-loading braces are used to modify the forces placed on the knee. These braces can help "unload" certain areas of your knee and move contact to less painful areas of the joint during weight-bearing activities. Depending on your symptoms and impairments, your physical therapist will help determine which brace may be best for you.

Activity recommendations. Physical therapists are trained to understand how to prescribe exercises to individuals with injuries or pain. Since knee OA is a progressive disease, it is important to develop a specific plan to perform enough activity to address the problem, while avoiding excessive stress on the knee joint. Activity must be prescribed and monitored based on the type, frequency, duration, and intensity of your condition, with adequate time allotted for rest and recovery. Research has shown that individuals with knee OA who walked more steps per day were less likely to develop functional problems in the future. Your physical therapist will consider the stage and extent of your knee OA and prescribe an individualized exercise program to address your needs and maximize the function of your knee.

Modalities. Your physical therapist may recommend therapeutic modalities, such as ice and heat, to aid in pain management.

If Surgery Is Required

The meniscus (the shock absorber of the knee) may be involved in some cases of knee OA. In the past, surgery (arthroscopy) to repair or remove parts or all of this cartilage was common. Current research, however, has shown that—in a group of patients who were deemed surgical candidates for knee OA with involvement of the meniscus—60% to 70% of those who first participated in a physical therapy program did not go on to have surgery. One year later, those results were unchanged. This study suggests that physical therapy may be an effective alternative for people with knee OA, who would prefer to avoid surgery.

Sometimes, however, surgical intervention, such as arthroscopy or a total knee replacement, may be recommended. There are many factors to consider when determining the appropriate surgical treatment, including the nature of your condition, your age, activity level, and overall health. Your physical therapist will refer you to an orthopedic surgeon to discuss your surgical options.

Should you choose to have surgery, your physical therapist can assist you prior to and following your surgery. The treatment you require following surgery will depend on a variety of factors such as the type of surgery performed, your level of function, and fitness prior to surgery. Contrary to popular belief, surgery is not the easy choice; you will still require treatment following your surgery to maximize your level of function.


Can this Injury or Condition be Prevented?

Many conditions, including knee OA, can be prevented with the right fitness and exercise program. Physical therapists are experts in movement. Some ways that a physical therapist can help you prevent knee OA include:

  • Developing an appropriate exercise program. Inactivity is a significant contributor to many problems that affect individuals, including knee OA. Strengthening the muscles around the knee, as well as surrounding joints, can help decrease stress to the knee joint. Exercises to improve flexibility can help you maintain motion in the knee joint, which helps keep the cartilage healthy. Your physical therapist can design an individualized treatment program to boost your strength and flexibility, based on your specific condition.

  • Weight loss. Excessive weight can increase stress to the knee joint, which in turn can contribute to the wearing away of the protective cartilage, leading to knee OA. Your physical therapist can assess your weight, perform testing to determine your fitness level, establish an exercise program, and recommend lifestyle changes. The therapist also may refer you to another health care provider, such as a dietician, for further guidance.

  • Activity modification. Individuals often move or perform activities in a way that is unhealthy or inefficient, or that places excessive stress on the body, including the knee joint. Your physical therapist can teach you better ways to move in order to ease stress on your body and your knees.

  • Taking a “whole body” approach to movement. Lack of strength, mobility, and flexibility in surrounding areas of the body such as the ankle, hip, and spine also can affect the knee. Taking these body regions into consideration is important to help prevent knee OA. Your physical therapist will work with you to help ensure your whole body is moving correctly, as you perform your daily activities.


Real Life Experiences

Luke is a 50-year-old businessman who has just moved his family to the city so he can start a new job. For the last 2 months, Luke has been working hard to fix up his family’s new home, carrying heavy boxes and moving furniture up and down stairs. He also has worked late into the night installing appliances.

After starting his new job last week, sitting through numerous orientation sessions and meetings, Luke notices that his right knee is really hurting. He is used to occasional knee discomfort, but this is the worst it has felt in a long time. During his junior year at college, Luke suffered a significant knee injury while playing basketball, which required surgery.

These days, Luke coaches his son’s Little League team, exercises several times each week, and plays pickup basketball with his friends. But occasionally, particularly after long road trips, his knee pain flares up, and he has to resort to medication, icing, and rest. These bouts are starting to occur more regularly. Luke decides it's time to seek a consultation with a physical therapist.

During Luke’s first appointment, his physical therapist asks him questions regarding his medical history, prior injuries, current symptoms and complaints, and goals for physical therapy. She examines his knee motion, strength, balance, and walking mechanics. She also uses special tests and measures to determine the nature of Luke’s pain, ruling out any other possible conditions.

Based on her findings, Luke's physical therapist determines that his current knee pain is a result of posttraumatic osteoarthritis. She diagnoses knee OA. She explains that his history of significant knee injury in college put him at risk of developing knee OA at a young age. The recent increased demand on his knee joint during his move is likely responsible for the current flare-up of pain and swelling.

Over the next 6 weeks, Luke works with his physical therapist to decrease his joint pain and improve his knee motion and full-body flexibility. She uses manual therapy techniques to improve the mobility of his knee joint. She prescribes a progressive exercise program to strengthen the muscles of his hip, knee, and core. She tailors this program so that Luke can complete it daily, based on the equipment available at his office gym facility.

Six weeks later, Luke is able to climb and descend stairs, squat, and jog without pain. He can sit through a full day of meetings without noticing stiffness or swelling in his knee. On his last day of therapy, Luke’s physical therapist provides him with a detailed home-exercise program and suggestions for maintaining the improvements he has made. With the summer approaching, he's preparing to coach his son's baseball tournaments—and take his family to the beach!

This story was based on a real-life case. Your case may be different. Your physical therapist will tailor a treatment program to your specific case.


What Kind of Physical Therapist Do I Need?

All physical therapists are prepared through education and clinical experience to treat a variety of conditions or injuries. You may want to consider:

  • A physical therapist who is experienced in treating people with knee osteoarthritis and after knee replacement surgery. Some physical therapists have a practice with an orthopedic focus.

  • A physical therapist who is a board-certified orthopedic clinical specialist. This physical therapist will have advanced knowledge, experience, and skills that may apply to your condition.

You can find physical therapists who have these and other credentials by using Find a PT, the online tool built by the American Physical Therapy Association to help you search for physical therapists with specific clinical expertise in your geographic area.

General tips when you're looking for a physical therapist (or any other health care provider):

  • Get recommendations from family and friends or from other health care providers.

  • When you contact a physical therapy clinic for an appointment, ask about the physical therapists' experience in helping people with arthritis.

  • During your first visit with the physical therapist, be prepared to describe your symptoms in as much detail as possible, and report activities that make your symptoms worse.

Greater Trochanteric Bursitis

Greater trochanteric bursitis (GTB) is an irritation of the bursa, a fluid-filled sac that sits on top of the greater trochanter, a bony prominence on the outside of the hip bone (femur). The bursa acts as a cushion to decrease friction between the outside of the hip bone and muscles attaching to the bone; bursitis results when the bursa on the outside of the hip bone becomes irritated. Greater trochanteric pain syndrome is the term used when the condition also includes irritation to the tendons of the gluteal muscles that sit beneath the bursa. 

Most often, GTB is the result of repetitive friction to the bursa due to a combination of muscle weakness and tightness affecting the outside of the hip. The condition is most often treated with physical therapy to restore normal function.

GTB may result from a combination of several different variables, including:

  • Gluteal muscle weakness

  • Iliotibial (IT) band (a thick band of tissue that runs along the outside of the leg from the pelvis to the knee) tightness

  • Hip muscle tightness

  • Abnormal hip or knee structure

  • Abnormal hip or knee mechanics (movement)

  • Improper movement technique with repetitive activities

  • Change in an exercise routine or sport activity

  • Improper footwear


images-1.jpeg


How Does it Feel?

People with GTB may experience:

  • Tenderness to touch on the outside of the hip

  • Pain that can vary from sharp to dull, and can radiate to the buttock, groin, thigh, or knee

  • Pain that is intermittent and symptomatic for a prolonged period

  • Pain when lying on the involved side

  • Pain and stiffness with prolonged sitting, walking (worst with the first few steps), negotiating stairs, or squatting

  • Pain that may increase during prolonged activity


How Is It Diagnosed?

The goals of the initial examination are to assess the degree of the injury, and determine the cause and contributing factors to it. GTB is a condition that develops as a consequence of repetitive irritation in the hip; it seldom results from a single injury. Your physical therapist will begin by gathering information about your condition, including your health history and your current symptoms. Your therapist will then examine your hip and thigh region to determine the presence of GTB. Your physical therapist may ask you questions about:

  • Your health history

  • Your current symptoms and how they may affect your typical day

  • The location and intensity of your pain, and how it may vary during the day

  • How the pain affects your activity level, and what you do to reduce the pain

  • How any injury may have occurred prior to your symptoms developing

  • How you have sought treatment, such as seeing other health care practitioners or having imaging or other tests done

Your physical examination will focus on the region of your symptoms, but also include other areas that may have been affected as your body has adjusted to pain. Your physical therapist may watch you walk, step onto a stair, squat, or balance on one leg. Following the interview and physical examination, your physical therapist will assess the results and develop an individualized treatment program to address your specific condition and goals. 

Imaging techniques, such as X-ray or MRI, are typically not needed to diagnose GTB.


How Can a Physical Therapist Help?

You and your physical therapist will work together to develop a plan to help achieve your specific goals. To do so, your physical therapist will select treatment strategies in any or all of the following areas:

  • Patient education. Your physical therapist will work with you to identify and change any external factors causing your pain, such as the type and amount of exercises you perform, your athletic activities, or your footwear. Your therapist will recommend improvements in your daily activities, and develop a personalized exercise program to help ensure a pain-free return to your desired activity level.

  • Pain management. Your physical therapist will design a program to address your pain that includes applying ice to the affected area as well as a trial of heat, such as a hot shower or heating pad. The exercises discussed below also can have a pain-reducing component. Your physical therapist also may recommend decreasing some activities that cause pain. Physical therapists are experts in prescribing pain-management techniques that reduce or eliminate the need for medication.

  • Range-of-motion exercise. Your low back, hip, or knee joint may be moving improperly, causing increased tension at the greater trochanter. Your physical therapist may teach you self-stretching techniques to decrease tension and help restore normal motion in the back, hip, and knee.

  • Manual therapy. Your physical therapist may apply “hands-on” treatments to gently move your muscles and joints, most likely in your low back, hip, or thigh. These techniques help improve motion and strength, and often address areas that are difficult to treat on your own.

  • Muscle strength. Muscle weaknesses or imbalances can result in excessive strain at the greater trochanter. Based on your specific condition, your physical therapist will design a safe, individualized, progressive resistance program for you, likely including your core (midsection) and lower extremity. You may begin by performing strengthening exercises lying on a table or at home on the bed or floor (eg, lifting your leg up while lying in different positions). You then may advance to exercises in a standing position (eg, standing squats). Your physical therapist will choose what exercises are right for you based on your age and physical condition.

  • Functional training. Once your pain, strength, and motion improve you will need to safely transition back into more demanding activities. To minimize the tension on the hip and your risk of repeated injury, it is important to teach your body safe, controlled movements. Based on your own unique movement assessment and goals, your physical therapist will create a series of activities to help you learn how to use and move your body correctly and safely.

Physical therapy promotes recovery from GTB by addressing issues, such as pain in the body structure, that is under stress from any lack of strength, flexibility, or body control. Your physical therapist may also recommend a period of relative rest, then help you slowly resume activities and carefully guide your progression. When GTB remains untreated, however, your pain will persist and result in long-term difficulty performing your desired activities.


Can this Injury or Condition be Prevented?

GTB may be the result of changes in the body’s shape, such as one leg being longer or shorter on the involved side. This condition can occur from an injury to the lower extremity or subtle differences that occur in the body’s growth and development.

Maintaining appropriate lower-extremity mobility and muscle strength, and paying particular attention to your exercise routine—especially changes in an exercise activity, the volume of exercises performed, and your footwear—are the best methods for preventing GTB.

Your physical therapist will help guide you through a process that will progressively reintegrate more demanding activities into your routine without overstraining your hip. Keep in mind that returning to activities too soon after injury can cause the condition to be more difficult to fix, and often leads to persistent pain.


Real Life Experiences

Karen is a 47-year-old teacher who is training for her first 5K road race. She runs 3 to 4 days each week, then walks the other days. Over the past 2 weeks, she has begun to experience pain in the outside of her right hip. Her pain is worse while running and lying on her right side; she experiences hip pain and stiffness when taking her first steps in the morning and walking up stairs, and also notes a dull ache with prolonged sitting and standing. She typically performs stretches for 5 minutes before her runs. Karen had not run consistently before she began training for the 5K.

Karen is concerned about the sharp hip pain she feels when running and her inability to complete her training due to pain. She is worried about her ability to perform daily activities and train for her upcoming race. She decides to seek the help of a physical therapist.

Karen's physical therapist takes a full history of her condition. Karen describes her typical daily running routine, including distance, pace, and running surface; her stretching routine; and her footwear. Her physical therapist then assesses Karen’s motion, strength, balance, movement, and running mechanics. He skillfully palpates (gently presses on) the front, side, and back of her hip to determine the precise location of her pain. Based on these findings, he diagnoses greater trochanteric bursitis.

Karen and her physical therapist work together to establish short- and long-term goals and identify immediate treatment priorities, including icing and stretching to decrease her pain, as well as gentle hip-strengthening exercises. They also discuss temporary alternative methods for Karen to maintain her fitness without continuing to aggravate her injury and prolong her recovery, such as swimming or biking. She is also prescribed a home-exercise program consisting of a series of activities to perform daily to help speed her recovery.

Together, they outline a 4-week rehabilitation program. Karen sees her physical therapist 1 to 2 times each week. He assesses her progress, performs manual therapy techniques, and advances her exercise program as appropriate. He advises her as to when she can begin to carefully resume running, and establishes a day-by-day plan to help her safely build back up to her desired mileage. Karen performs an independent daily exercise routine at home, including stretching and strengthening activities, which her physical therapist modifies as she regains strength and movement.

After 4 weeks of patient work, Karen no longer experiences pain or stiffness in her hip, and resumes her desired training program in preparation for her upcoming 5K race.

On the day of the race, Karen runs pain free and crosses the finish line in a personal best time!


What Kind of Physical Therapist Do I Need?

All physical therapists are prepared through education and experience to treat greater trochanteric bursitis. However, you may want to consider:

  • A physical therapist who is experienced in treating people with greater trochanteric bursitis. Some physical therapists have a practice with an orthopedic or musculoskeletal focus.

  • A physical therapist who is a board-certified clinical specialist or who completed a residency or fellowship in orthopedic or sports physical therapy. This physical therapist has advanced knowledge, experience, and skills that may apply to your condition.

You can find physical therapists who have these and other credentials by using Find a PT, the online tool built by the American Physical Therapy Association to help you search for physical therapists with specific clinical expertise in your geographic area.

General tips when you're looking for a physical therapist (or any other health care provider):

  • Get recommendations from family and friends or from other health care providers.

  • When you contact a physical therapy clinic for an appointment, ask about the physical therapists' experience in helping people who have greater trochanteric bursitis.

  • During your first visit with the physical therapist, be prepared to describe your symptoms in as much detail as possible, and describe what makes your symptoms worse.
