Isometric Shoulder External Rotation
Isometric contraction of the shoulder external rotators (infraspinatus and teres minor) without joint movement. The first stage of rehabilitation in reactive rotator-cuff tendinopathy — reduces pain through central analgesic mechanisms without loading the inflamed tendon.
How to perform
- Starting position. Stand next to a wall, with the elbow on the affected side flexed to 90° and tucked against the trunk.
- Step 2. Place a rolled towel between the elbow and the trunk to keep the arm aligned.
- Step 3. With an open hand and a neutral wrist, press the back of the hand against the wall as if performing external rotation — but without allowing the movement.
- Step 4. Apply about 70% of maximum force and hold for 30–45 seconds, breathing normally.
- Return. Gradually release the contraction, rest for 1 minute, and repeat. There should be no pain during the contraction — if there is, reduce the intensity.
When not to perform
- Complete rotator-cuff rupture
- Post-operative shoulder in the first 6 weeks
- Anterior glenohumeral instability
- Uncontrolled arterial hypertension (isometrics raise intrathoracic pressure)
- Recent fracture of the humeral head
- Recent shoulder dislocation

Side-Lying Shoulder Wiper
A wide windshield-wiper-like sweeping motion of the shoulder in side-lying, covering the range of internal and external rotation in a controlled manner. Isolates the subscapularis and the posterior cuff simultaneously — useful for recovering range and coordination after immobilization.

Side-Lying Eccentric External Rotation
Eccentric variant of side-lying external rotation with a dumbbell. The focus is on the controlled lowering phase — essential in rotator-cuff tendinopathy rehabilitation, when the patient already tolerates dynamic load but needs to remodel the tendon with prolonged loading.

Banded External Rotation
A functional variant of external rotation, performed standing with elastic resistance. Excellent for progression and maintenance in chronic rotator-cuff tendinopathy.
