Rotator Cuff Tendinopathy / Subacromial Pain

Load-related rotator cuff pain, often aggravated by elevation and overhead activity; modern management emphasizes active rehabilitation rather than a purely mechanical 'impingement' model.

THE MSK CLINICAL STORY

The shoulder that disliked shelves—but wasn't necessarily trapped

A fictional teaching case. Follow the clues, enjoy the conversation, and make the decisions a thoughtful clinician would make—not an instant diagnosis from a single symptom.

Scene 01 · The patient walks in

A painter reaches overhead all week, then notices a familiar ache lifting a kettle to the top shelf. His friend says, 'Your tendon is being pinched by a bone, forever.' The shoulder deserves a better script.

A little clinic conversation

Patient: 'So there is no room inside my shoulder?' Therapist: 'We don't have to blame a tiny tunnel for every painful reach.'

Scene 02 · Follow the clues

Gradual load-related shoulder pain and painful resisted elevation can fit rotator cuff-related pain. The old one-size-fits-all impingement explanation oversimplifies the problem.

Plot twist · What could fool us?

Painful tests can overlap across shoulder conditions. Trauma with sudden major weakness or marked loss of active elevation changes the referral pathway.

Choose your learning lens

Same clinical case, two ways to understand it. The complete examination and treatment guide is still available below.

In everyday words

Your shoulder tendons may be sensitive to the amount of work they are doing. We'll adjust aggravating loads and build capacity gradually rather than permanently ban overhead tasks.

Scene 03 · The rehabilitation journey

Settle painful overload → progressive resisted cuff and scapular work → overhead strength and confidence appropriate to the job.

Structures Involved

  • Supraspinatus/infraspinatus/subscapularis tendons
  • Subacromial bursa may coexist
  • Scapular and thoracic contributors

Mechanism / Why It Happens

  • Repeated overhead load
  • Sudden increase in training/work volume
  • Reduced tendon capacity
  • Age-related tendon change with load sensitivity

Classification / Grades

  • Noncalcific tendinopathy
  • Calcific tendinopathy
  • Partial-thickness cuff tear may exist on same continuum

Symptoms

  • Anterolateral shoulder pain
  • Painful overhead reach
  • Night pain in some patients
  • Pain with resisted shoulder loading

Clinical Signs

  • Painful arc
  • Pain/weakness with resisted abduction or external rotation
  • Scapular movement impairment in some patients
  • ROM often relatively preserved

Red Flags & Referral Clues

  • Acute traumatic pseudoparalysis
  • Suspected fracture/dislocation
  • Progressive neurologic deficit
  • Systemic symptoms/infection
  • Unexplained severe night pain or malignancy concerns

Diagnostic Examination

How to perform the tests — step by step

Each test includes patient setup, therapist position, hand placement, exact performance, positive finding and clinical interpretation.

Painful Arc

Assess pain during loaded/elevated shoulder range.

Patient position

Standing or sitting.

Therapist position

Observes from front/side.

Hand placement

None required.

How to perform

  1. 1Ask the patient to actively abduct/elevate the arm through full available range.
  2. 2Note the angle and location of pain.
  3. 3Observe for scapular substitution.

Positive sign

Concordant shoulder pain during a mid-range arc, commonly around 60–120°.

Interpretation

Supports subacromial/rotator-cuff-related pain but is not specific alone.

Hawkins-Kennedy

Provocative test for subacromial/rotator-cuff-related shoulder pain.

Patient position

Sitting or standing; shoulder and elbow at about 90° flexion.

Therapist position

Beside/in front of the patient.

Hand placement

Support elbow with one hand and control wrist/forearm with the other.

How to perform

  1. 1Bring shoulder to 90° flexion.
  2. 2Maintain elbow at 90°.
  3. 3Gently internally rotate the shoulder.
  4. 4Ask whether familiar shoulder pain is reproduced.

Positive sign

Concordant anterolateral shoulder pain.

Interpretation

Supports rotator-cuff/subacromial pain as part of a clinical cluster.

Jobe / Empty Can

Assess supraspinatus-related pain/strength.

Patient position

Standing or sitting; arms elevated in scapular plane around 90°.

Therapist position

In front of patient.

Hand placement

Resistance over distal forearms.

How to perform

  1. 1Position arms in scapular plane.
  2. 2Apply downward resistance while patient maintains elevation.
  3. 3Compare pain and strength sides.

Positive sign

Pain and/or clear weakness.

Interpretation

Supports supraspinatus/rotator cuff involvement; marked weakness after trauma warrants tear assessment.

Differential Diagnosis

  • Full-thickness rotator cuff tear
  • Adhesive capsulitis
  • Cervical radiculopathy
  • Glenohumeral OA
  • Anterior instability
  • AC joint pain

Investigations / Imaging

  • Imaging is not routinely required for uncomplicated initial presentation.
  • Ultrasound/MRI may be considered for traumatic weakness, failed rehabilitation, suspected major tear or surgical planning.

Complete Rehabilitation Plan

From protection to full function

Phase 1 — Load Modification & Pain-Controlled Activation

Reduce irritability without unnecessary rest.

What to do

  • Education and temporary modification of provocative overhead volume
  • Begin cuff/scapular motor-control work
  • Maintain comfortable ROM

Exercise dosage

  • Isometric ER/abduction: 3–5 x 20–45 s at tolerable effort
  • Scapular control: 2–3 x 10–15
  • Comfortable elevation ROM: 1–3 x 10

Progress when

  • Daily tasks less irritable
  • Able to load cuff without prolonged flare

Phase 2 — Resistance & Capacity

Increase rotator cuff and scapular strength/endurance.

What to do

  • Progressive ER/IR resistance
  • Scaption/elevation loading
  • Row/press variants
  • Thoracic/scapular integration

Exercise dosage

  • Resistance exercises: 3–4 x 6–15, 2–4 sessions/week
  • Progress load when technique is good and symptoms settle by next day

Progress when

  • Improved strength
  • Reduced painful arc
  • Overhead function improving

Phase 3 — Overhead / Sport-Specific Return

Restore high-load and repetitive overhead capacity.

What to do

  • Overhead pressing/throwing progression
  • Plyometric/rapid cuff work where relevant
  • Work/sport load planning

Exercise dosage

  • 2–3 higher-load sessions/week
  • Throwing/overhead volume increased gradually with recovery monitoring

Progress when

  • Near-full ROM
  • Strong cuff/scapular function
  • Target work/sport volume tolerated

Manual Therapy — Role & Application

  • Glenohumeral, scapular, cervical or thoracic manual therapy may be used for short-term pain relief or mobility restriction.
  • Soft-tissue techniques may be adjunctive.
  • Manual therapy should be paired with active rehabilitation.

Modalities — Use / Avoid

  • Therapeutic ultrasound is not recommended for calcific or noncalcific rotator cuff tendinopathy in the 2025 CPG.
  • Shockwave may be considered for calcific tendinopathy, but not routinely for noncalcific tendinopathy.
  • Taping may provide short-term pain reduction when added to exercise.

Return / Discharge Criteria

  • Functional pain controlled
  • Near-full task-specific ROM
  • Adequate cuff/scapular strength/endurance
  • Overhead workload tolerated
  • Sport-specific progression completed

Common Clinical Mistakes

  • Calling every shoulder pain 'impingement' without differential screening
  • Complete rest
  • Using ultrasound as primary treatment
  • Skipping progressive cuff loading

Clinical Pearls

  • Exercise is first-line.
  • Manual therapy can help short-term symptoms but does not replace load-capacity rehabilitation.
