It is important to test an individual’s strength as a part of a thorough initial evaluation. Re-testing at three to four weeks intervals is ideal to determine their progress from treatment from the prescribed exercises.

This video involves strength testing for shoulder external rotation utilizing a hand-held dynamometer (HHD). The muscles being tested are infraspinatus and teres minor.

She is performing a “make” test, which means achieving maximal isometric effort against resistance.

The standard way of assessing strength for shoulder external rotation is in supine. This video also includes an alternative version of testing in prone.

✅ Body Position: Sitting or prone
✅ Stabilization: Inner aspect of the distal humerus
✅ Test Position: Elbow flexion to 90° with external rotation of the humerus
✅ Position of HHD: Proximal to the styloid process
✅ Pressure: In direction of shoulder internal rotation

Objective testing with a HDD is essential to determine the effectiveness of your treatment (exercise) intervention.
