Anterior Load and Shift Test
-
Anterior Load and Shift test is used to test for Anterior Instability of the shoulder.
- Have the patient lie supine with the shoulder at 40-60 degrees of abduction and 90 degrees of forward flexion.
- Axially load the humerus and apply anterior/posterior translation forces.
- Compare to the contralateral side.
- Anterior Load and Shift test is Positive when there is increased translation of the humeral head compared to the contralateral side.
- The load and shift test can be used to classify degrees of instability based on distance of humeral head translation:
- 1+: 0 to 1 cm of translation to before glenoid rim.
- 2+: 1 to 2 cm of translation to glenoid rim.
- 3+: more than 2 cm translation or over glenoid rim.
- Sensitivity: 50-55 %
- Specificity: 78-100 %
