Positions and limbs used for each isometric strength test
| Direction | Position(s)* | ‘Test’/surgical limb | Opposite limb |
| Abduction | Neutral (0° of abduction) | X | |
| Horizontal (90° of abduction) | X | X | |
| Flexion | Neutral (0° of flexion) | X | X |
| Internal/external rotation | Horizontal with elbow flexed (45° of abduction; 0° of external rotation; 90° of elbow flexion) | X | |
| Horizontal and rotated with elbow flexed (90° of abduction and external rotation†; 900 of elbow flexion) | X | X |
*A straight arm (ie, 0° of elbow flexion) will be used across all tests, unless noted otherwise.
†The maximal external rotation angle achievable if less than 900.
