Shoulder ER 90 Supine

Setup

Frame Setup Diagram

1: Lie supine, test arm abducted to 90°, elbow flexed 90° and forearm vertical

2: Support humerus/elbow with foam block or towel, ensuring humerus remains in plane of scapula while in 90° abduction

3: Position body and housing, aligning flat sensor pad to level of dorsal aspect of wrist at right angles to forearm.

Cues

1: Test unilaterally

2: Describe humeral rotation axis

3: Set scapular, drawing humeral head, squeeze wrist into pad, maintaining scapular and trunk position

4: Visualise axis through humerus, rotating shoulder to generate this ER torque while keeping elbow still

5: NB: Tester may need to monitor humeral head and or elbow, providing feedback for those with poor control or instability.

6: Build to maximum force over 5 seconds
