Where is the Supraspinatus?
Symptoms of a Supraspinatus Tear
The supraspinatus muscle is the most often damaged rotator of all 4 cuff muscles.
The supraspinatus plays a key role in the proper function of the shoulder especially on the top.
Many rotator cuff muscles can be a source of pain for many reasons such as inflammation, muscle degeneration or muscle tears.
Fraying of the supraspinatus tendon surface, partial thic
kness tears, and full thickness supraspinatus tears are all quite common.
The drop arm test is done by raising the arm to the side (abducted out 90 degrees) which is horizontally aligned with the shoulders. The arm must be lowered slowly and with control. Pain can indicate supraspinatus damage.
