How to Tell the Difference: Key Symptoms
Distinct clinical differences between the two conditions:
- Frozen Shoulder (Adhesive Capsulitis): Loss of BOTH active and passive motion. Even when a doctor tries to lift your arm, the joint is physically blocked due to capsular tightness.
- Rotator Cuff Tear: Passive motion is usually preserved! You cannot lift your arm yourself (active weakness), but when a doctor lifts your arm for you, it moves with less restriction, though painful.
- Pain Timing: Frozen shoulder typically presents with agonizing night pain when lying on the affected side during its initial 'freezing' phase.
Diagnostic Evaluation & Shoulder Imaging
Physical examination includes specific tendon impingement tests (Neer's, Hawkins-Kennedy, Empty Can test) and capsular pattern checks. Shoulder MRI or ultrasound is ordered to assess whether a rotator cuff tendon has a partial or full-thickness tear.
Treatment & Rehabilitation Guidelines
Frozen shoulder is managed with intra-articular capsular steroid/hydrodilatation injections and stretching. Rotator cuff tears respond to subacromial injections, physical therapy, or keyhole arthroscopic repair for complete tears.
