To access the supraspinatus tendon effectively, what arm positioning is recommended?

To access the supraspinatus tendon effectively, internally rotating, extending, and abducting the humerus is the recommended arm positioning. This position facilitates the proper alignment of the shoulder joint and enhances the visibility and accessibility of the supraspinatus tendon, which is located at the top of the shoulder, specifically within the rotator cuff.

When the arm is abducted and extended, this positioning allows for greater clearance as the tendon is positioned just below the acromion, making it easier for a practitioner to palpate and assess the tendon during a treatment session. Internally rotating the humerus places the tendon in a more accessible orientation, also assisting in alleviating any potential impingements that might occur from other structures in the shoulder.

This combination of movements effectively creates space in the subacromial area, where the supraspinatus tendon is frequently assessed and treated in therapeutic settings.
