• Most useful single change: Check your state rules and your insurance before booking directly.
• Commonest mistake: Expecting passive treatment alone to resolve the problem.
• See a doctor if any of the signs under "When to speak to a doctor" below apply to you.

In depth

Physical therapists are licensed health professionals who assess and treat problems with movement and function. In the US, entry-level physical therapists now graduate with a Doctor of Physical Therapy (DPT) degree and must pass a national exam and hold a state license. They work in hospitals, outpatient clinics, schools, sports facilities, nursing homes and patients' homes.

Physical therapy focuses on helping you move better and do what matters to you. The core of most treatment is exercise and education, tailored to your problem, goals and abilities. Hands-on techniques, such as joint mobilization and soft tissue work, and other approaches like heat may be used, but mainly to support active treatment rather than replace it.

Most of the benefit comes from what you do between sessions. Therapists design home exercise programs and teach you how to manage your condition independently. The aim is to give you the skills and confidence to stay active and prevent recurrence, not to keep you coming back indefinitely.

Causes and risk factors

• Back, neck and joint pain
• Recovery after surgery such as joint replacement
• Sports injuries and sprains
• Balance problems and falls
• Neurological conditions such as stroke or Parkinson's disease
• Pelvic floor problems, including after pregnancy

How it is checked

Your first visit usually involves a detailed evaluation. The therapist asks about your symptoms, history, daily activities and goals, then assesses movement, strength, flexibility, balance and function. They also screen for warning signs that need medical attention and will refer you to a doctor if needed.

Based on the evaluation, the therapist explains what they think is going on and agrees a plan with you, including goals, the type of treatment and the expected number of visits. Progress is measured at follow-up sessions, and the plan is adjusted as needed.

Treatment and support options

Exercise therapy

Exercises are chosen to improve strength, mobility, endurance, balance or control, depending on your needs and goals. They start at a level you can manage and are progressed gradually, by adding load, repetitions or difficulty, as you improve. Understanding why each exercise is prescribed, and what it should feel like, helps you do it well, notice progress and stay motivated between sessions.

Education and self-management

Learning about your condition, how pain works, and how to pace activity and manage flares is a key part of treatment. Understanding that pain does not always mean damage can reduce fear of movement, which is one of the main things that keeps people stuck. Your therapist can also advise on sleep, work tasks and returning to sports, so the plan fits your everyday life.

Manual therapy

Hands-on techniques, such as joint mobilization, manipulation and soft tissue work, can ease pain and improve movement in the short term. They are most effective as part of a plan that includes exercise, using the window of reduced pain to move more. If most of your sessions are passive treatment with little exercise, ask your therapist how manual therapy fits into your overall program.

Specialized therapy

Some therapists have advanced training and board certification in areas such as orthopedics, sports, neurology, geriatrics or women's health, including pelvic floor therapy. If you have a specific condition, ask whether a specialist would be helpful.

Prevention

• Do your home exercise program as prescribed
• Continue exercises after symptoms improve to prevent recurrence
• Stay physically active between sessions
• Report changes in symptoms promptly
• Ask for a plan to continue on your own after discharge

Day to day

Fitting exercises into your daily routine makes them easier to keep up. Linking them to existing habits, such as after brushing your teeth, helps. If exercises are too hard, painful or time-consuming, tell your therapist so they can be adjusted.

When you finish physical therapy, you should have a clear plan for continuing on your own. Ask how to progress exercises and what to do if symptoms return. Staying active long term is the best way to maintain your gains.

For specific groups

Medicare beneficiaries

Medicare Part B covers outpatient physical therapy when it is medically necessary and provided by a qualified therapist under a plan of care. The Part B deductible and coinsurance apply. There is no hard yearly cap on visits, but above a certain spending level your therapist must confirm that continued therapy is medically necessary. Medicare Advantage plans may have their own referral and authorization rules.

Children

Pediatric physical therapists help children with developmental delays, sports injuries and conditions affecting movement, such as cerebral palsy. Therapy is often play-based and involves parents in carrying exercises into daily routines. Infants and toddlers with delays may qualify for state early intervention programs, and school-age children with disabilities may receive therapy through their school.

People after surgery

Physical therapy after surgery, such as joint replacement or spinal surgery, helps restore movement, strength and confidence. It often starts in the hospital, sometimes on the day of surgery, and continues at home or in a clinic. Following your surgeon's precautions, attending sessions and doing the home program every day all support a faster, safer recovery.

Questions to ask your doctor

• Would physical therapy help my condition?
• Do I need a referral for insurance coverage?
• What type of physical therapist should I see?
• How many visits should I expect?
• What results should I expect, and by when?
• What should I do if my symptoms do not improve?

More questions, answered

Do I need a referral to see a physical therapist?

All states allow some form of direct access, but rules vary and some limit the number of visits or time without a referral. Your insurance may also require a referral. Check your state rules and plan.

How many sessions will I need?

It depends on your condition, goals and progress. Some problems need only a few visits with a home program, while others require longer treatment. Your therapist will give an estimate and review it as you progress.

Is physical therapy painful?

Some exercises may cause mild discomfort, especially early on, as you ask tissues to do more than they are used to. Treatment should not cause severe pain or pain that lasts long after the session. Mild soreness that settles within a day is common. Tell your therapist if something hurts so they can adjust the exercise, the load or the number of repetitions.

Can physical therapy be done by telehealth?

Yes. Many therapists offer telehealth visits for assessment, exercise instruction and progress checks. It works well for many conditions, though some hands-on assessment may need in-person visits. Check coverage with your insurance.

What is the difference between a physical therapist and a physical therapist assistant?

Physical therapist assistants complete an associate degree and are licensed or certified in most states to provide treatment under the direction and supervision of a physical therapist. The physical therapist carries out the evaluation, sets and updates the plan of care, and decides when you are ready for discharge. You can ask who will be treating you at each visit.

What should I wear to physical therapy?

Wear comfortable clothing that lets you move freely and gives access to the area being treated, such as shorts for a knee problem or a loose top for a shoulder. Supportive athletic shoes are useful for exercise and balance work. Bring your insurance card, a list of medicines, any imaging reports and a note of your main goals.

When to speak to a doctor

Go to the emergency room rather than physical therapy for numbness around the genitals, buttocks or inner thighs, bladder or bowel changes, or weakness in both legs, and call 911 after a serious injury. See your doctor promptly for pain with fever, unexplained weight loss, a history of cancer, or progressive limb weakness.
