Clinical Roadmap: Adhesive Capsulitis

Adhesive Capsulitis

Thinking Clinically · A guide for PT students and new grads

The patient is a middle-aged adult with months of gradually worsening shoulder pain and stiffness, and trouble putting on a shirt, reaching behind the back, and sleeping on that side. A painful shoulder is common. A painful shoulder that has genuinely stopped moving, actively and passively, is a much smaller category. This roadmap shows how to recognize, confirm, differentiate, and treat adhesive capsulitis, and how to match treatment to how irritable the shoulder is right now.

1

Recognize It

• Most commonly a middle-aged adult. Risk factors include diabetes, thyroid disease, age 40 to 65, female sex, and a prior episode in the other shoulder
• Gradual onset of pain and stiffness, often with no clear injury. Pain may dominate early, with stiffness taking over later
• Both AROM and PROM restricted, with external rotation often disproportionately limited, followed by abduction, flexion, and internal rotation
• Night pain and trouble sleeping on the involved side, with increasing trouble reaching overhead, behind the back, and away from the body
• Neurological findings typically absent, and no single traumatic event required
• Ask first: is passive ROM truly restricted, in a pattern that looks like a globally stiff joint? A painful shoulder with near-full PROM points elsewhere

2

Confirm It

• History: gradual onset, no memorable injury, and deep aching pain that gives way to stiffness. Functional triggers like putting on a shirt or bra, washing hair, and reaching into a back pocket track how restricted the joint is.
• The 2013 guideline description: gradual, progressive pain with night pain and pain at end range, and painful, restricted active and passive ROM in elevation and rotation, present for at least 1 month and plateaued or worsening.
• Classification: ROM loss of more than 25% in at least 2 planes, and passive external rotation loss of more than 50% compared with the uninvolved shoulder.
• PROM is the key exam finding: restriction in multiple planes, external rotation commonly the most limited, and a firm, capsular end-feel that is painful or guarded depending on irritability.
• AROM and PROM restricted together points to the joint. AROM much worse than PROM points to a force-production problem or pain inhibition.
• Special tests are secondary, and no validated cluster exists. A stiff, irritable shoulder makes many tests painful. Build the pattern.
• Reconsider the diagnosis if PROM is essentially normal, radiographs show glenohumeral arthritis, rotation increases rather than decreases as the arm moves from 45° to 90° of abduction, subscapularis palpation reproduces the pain, or neural tension testing reproduces the symptoms.

Differentiate It

Condition	More likely if
Rotator cuff-related shoulder pain	PROM relatively preserved, pain greater than stiffness, and resisted cuff testing reproduces symptoms
Rotator cuff tear	Substantial weakness, AROM much worse than PROM, positive lag signs, or traumatic onset
Glenohumeral OA	Joint-line pain, crepitus, mechanically aggravated symptoms, and degenerative change on radiographs
Cervical radiculopathy	Neck pain, symptoms radiating distally, numbness or tingling, myotomal weakness or reflex change
Non-musculoskeletal causes	Systemic or constitutional symptoms, severe unremitting pain, or pain that doesn’t behave mechanically

Don’t Miss This

• Neck pain, symptoms radiating past the elbow, numbness or tingling, or dermatomal, myotomal, or reflex change points toward the neck.
• Systemic symptoms, unremitting non-mechanical pain, fever, redness, or swelling need medical evaluation, not routine rehab.

Treat It

• Start with education. The joint is irritated and stiff, not weak or fragile, and recovery is measured in months. Cover the natural course, activity modification without stopping movement, and matching stretch intensity to irritability. Avoid saying the capsule must be “broken loose.” More pain does not mean more progress.
• Classify irritability first, and reclassify every visit. Irritability is how much stress the tissue tolerates today. The key finding is the relationship between pain and active and passive movement.

Irritability	What You See	Treatment Emphasis
High	Pain over 7/10, constant night or rest pain, high disability, pain before end range, AROM much less than PROM	Activity modification, heat or electrical stimulation for pain, grade I to II mobilization in pain-free ranges, pain-free PROM and AAROM
Moderate	Pain 4 to 6/10, intermittent night pain, pain at end range, AROM close to PROM	Moderate mobilization and gentle-to-moderate stretching into tissue resistance without post-treatment soreness; integrate new motion with reaching
Low	Pain under 4/10, no night pain, minimal disability, pain only with overpressure at end range	End-range grade III/IV mobilization, progressive sustained stretching, and higher-level functional and recreational movement

• Manual therapy is an adjunct.
  Use gentle oscillations and lower grades early, and keep it when it brings an immediate gain in ROM or comfort. Scale it back if the patient becomes dependent on passive treatment. Heat or TENS can help comfort but shouldn’t be the main strategy.
• Phase 1 (high irritability): pendulums, table slides, supported flexion, gentle external rotation, and submaximal isometrics, in short, frequent, low-intensity sessions.
• Phase 2 (moderate): wall slides, active-assisted elevation, wand external rotation, light resisted rotation, and scapular strengthening. Progress from assisted to active to end-range control.
• Phase 3 (low): progressive rotator cuff strengthening, scaption, rows, overhead pressing, and functional lifting. Progress from ROM to control to resistance to function.
• Track more than a ROM number.
  Use the SPADI, DASH, or ASES with pain, AROM, and PROM, and progress by sleep, tolerance, and function.
• Coordinate with the physician.
  The 2013 guideline rates the evidence as strong that corticosteroid injection plus stretching beats stretching alone at 4 to 6 weeks, and a 2026 meta-analysis found greater short-term ROM and function gains with injection plus PT, though not for pain. Manipulation under anesthesia is a weak-evidence option for patients who plateau.
• Set expectations.
  Recovery often takes many months and sometimes longer than a year. Most patients improve with conservative care, though some keep mild residual limits. Diabetes and high irritability are linked to a slower course.
• Know when to reconsider:
  ROM declining despite appropriate care, clearly worsening symptoms, new neurological findings or significant weakness, new trauma, or non-mechanical or systemic symptoms.

Key Takeaway

When the shoulder is painful and globally stiff, don’t let a positive special test pull you away from the passive ROM exam. Multi-plane active and passive restriction, disproportionate external rotation loss, and a fitting history matter more than any single test, and the dose should follow irritability.
