Do I need a referral to see a physical therapist?

Most U.S. states allow direct access — you can self-refer for an evaluation. Insurance coverage rules vary, so check whether your plan requires a physician referral for reimbursement.

How long does physical therapy take to work?

Most people feel meaningful change within 4–6 visits. A full course of care typically runs 6–12 weeks depending on the condition, severity, and your goals.

Is physical therapy covered by insurance?

Yes — Medicare, Medicaid, and most commercial plans cover medically necessary PT. Coverage rules around visit caps, copays, and prior authorization differ by plan.

Will physical therapy hurt?

PT shouldn't make pain worse. Some discomfort during loading exercises is normal, but a good therapist will keep treatment within a tolerable range and progress as you recover.

What should I wear to my first PT appointment?

Loose, comfortable clothing you can move in — athletic wear, shorts for lower-body injuries, a tank or t-shirt for shoulder or neck issues.

What's the difference between a physical therapist and a chiropractor?

PTs treat the full musculoskeletal and neuromuscular system across the lifespan with exercise, manual therapy, and movement retraining. Chiropractors focus primarily on spinal manipulation. Many people benefit from both, depending on the condition.

Overview

What physical therapists do, in plain language

Physical therapy (PT) is a licensed health profession focused on diagnosing and treating movement disorders. PTs help people recover from injury and surgery, manage chronic pain, regain strength after a hospital stay, and improve mobility as they age.

Care is hands-on and active: a typical visit combines a movement assessment, manual therapy, and a personalized exercise plan you'll progress between sessions. Most plans run 6–12 weeks, with the goal of returning you to the activities you care about — work, sport, parenting, independent living.

Modern PT is evidence-based. Therapists draw on biomechanics, pain science, and rehabilitation research to tailor care to your specific goals, not a one-size-fits-all protocol.
