Resisted internal rotation

Positioning.

The subject stands with the upper arm against the body and the elbow flexed to a right angle. The forearm is held in the sagittal
plane, so keeping the shoulder in a neutral position. The examiner stands level with the subject’s arm. He places one hand on the opposite shoulder and the other hand against the inner and distal aspect of the forearm.

Procedure.

Resist the subject’s attempt to pull her hand towards her.

Common mistakes:

• The shoulder is allowed to abduct.
• Movement is allowed at the shoulder

Common pathological situations:

• Pain is the result of a lesion of the subscapularis, pectoralis major or latissimus dorsi tendons or muscles, and more rarely of the teres major.
• Isolated weakness occurs in total rupture of the subscapularis tendon.
