Frozen Shoulder Treatment: What Physical Therapy Does

What is frozen shoulder, and why does PT help?

Frozen shoulder (adhesive capsulitis) is a condition in which the joint capsule surrounding the shoulder joint becomes inflamed, thickened, and tight, resulting in a shoulder that is painful and progressively loses its ability to move freely. It is classically described as moving through three stages — freezing (painful), frozen (stiff), and thawing (gradual recovery) — over 18–36 months 1Ref 1Ramirez J (2019).Adhesive Capsulitis: Diagnosis and Management.Frozen shoulder natural history (18–36 months self-limiting); corticosteroid injection combined with physiotherapy shows superior short-term outcomes versus exercise alone; surgical options (MUA, arthroscopic capsule release) reserved for refractory cases.

Physical therapy works because the primary driver of lost motion is that tightened capsule — targeted, consistent stretching gradually restores length and flexibility to the tissue. Manual therapy by a skilled PT can address pain, improve circulation to the joint, and help you move your shoulder through ranges that would be too painful to attempt on your own at first.

What does a physical therapy session for frozen shoulder look like?

A PT will assess how far your arm can move in several directions — forward, to the side, behind your back, and across your chest. Treatment commonly includes:

Manual therapy (hands-on work): The PT may use joint mobilizations to gently move the humeral head within the socket, helping to stretch the capsule and reduce pain signals.

Passive and active-assisted stretching: You will be guided through stretches in positions you cannot comfortably reach on your own — cross-body stretch, doorway stretch (arms at 90 degrees against a door frame), and the pendulum exercise (letting gravity gently mobilize the joint).

Strengthening exercises: Once pain and motion allow, exercises rebuild the muscles around the shoulder — rotator cuff and scapular stabilizers — so the restored range of motion is supported and stable. Evidence supports an active, task-oriented rehabilitation program for persistent shoulder conditions 2Ref 2Desmeules F, Roy JS, Lafrance S, Charron M, Dubé MO, Dupuis F, Beneciuk JM, Grimes J, Kim HM, Lamontagne M, McCreesh K, Shanley E, Vukobrat T, Michener LA (2025).Rotator Cuff Tendinopathy Diagnosis, Nonsurgical Medical Care, and Rehabilitation: A Clinical Practice Guideline.Evidence-based CPG recommending active, task-oriented rehabilitation (exercises and education) as the cornerstone treatment for persistent shoulder conditions including adhesive capsulitis-adjacent presentations.

Heat before stretching: Some clinics use heat to warm the tissue and make it more pliable. Evidence for adjunct modalities alone is modest, but they can make stretching more comfortable.

Home program: What you do between sessions matters enormously. Your PT will prescribe a set of exercises — typically performed once or twice daily — and teach you how to progress them safely.

Which exercises are commonly used for frozen shoulder?

The following are exercises frequently prescribed for frozen shoulder. Timing and intensity matter — introduce these with a clinician's guidance:

• Pendulum swings: Stand and lean forward, letting your affected arm hang. Gently swing it in small circles using momentum, not muscle force. This decompresses the joint.
• External rotation with a stick: Hold a cane or broom handle horizontally. Use your unaffected arm to gently push the affected arm outward. Hold briefly and release.
• Shoulder elevation (table slide): Sit at a table and rest your forearm on a smooth surface. Slide your arm forward and upward, letting the table support the weight.
• Cross-body stretch: Gently pull the affected arm across your chest with the other hand. Hold for 30 seconds.
• Sleeper stretch: Lie on your affected side and use the other arm to gently rotate the wrist downward. This targets internal rotation, which is often the most restricted direction.

Pain during these exercises should be mild — a 3 or 4 out of 10. Sharp or escalating pain is a signal to ease off and discuss with your PT.

Is physical therapy alone enough, or are other treatments needed?

For many people, PT combined with a short course of anti-inflammatory medication (discussed with a physician) is the primary treatment. A corticosteroid injection into the joint, given by an orthopedic physician, can reduce inflammation enough to make PT exercises more productive, especially in the painful freezing phase; the combination of injection plus structured exercise has shown superior short-term outcomes in some trials versus exercise alone 1Ref 1Ramirez J (2019).Adhesive Capsulitis: Diagnosis and Management.Frozen shoulder natural history (18–36 months self-limiting); corticosteroid injection combined with physiotherapy shows superior short-term outcomes versus exercise alone; surgical options (MUA, arthroscopic capsule release) reserved for refractory cases.

In cases where PT and injections do not restore motion after many months, a physician may recommend manipulation under anesthesia (MUA) or arthroscopic capsule release. These are considered only after adequate conservative care has been tried.

The right specialist for frozen shoulder is a physical therapist for the exercise and manual therapy component, working alongside an orthopedic physician or sports medicine doctor if injections or surgical options become relevant.

What should I do if I cannot afford multiple PT sessions?

PT is most effective when sessions are regular and the home program is consistent. If visits are limited by cost or access, ask your PT to prioritize teaching you a thorough home program in your first session and schedule follow-ups at longer intervals. Some people do well with an initial evaluation and instruction, then return for a progress check every few weeks rather than multiple visits per week.
