Load and Shift Test is a shoulder examination used to assess anterior and posterior instability.
- Patient seated with arm in dependent position.
- Examiner applies pressure over humerus to “load” the GH joint while stabilizing shoulder, examiner then moves the shoulder anterior, posterior & anterior.
Positive Excessive translation (should be <25% anteriorly or <50% posteriorly) → Shoulder instability.
Positive Local Pain → rotator cuff ligament/tendon damage.
A palpable click or clunk may be noted as the humerus subluxates in & out of the glenoid fossa.
