EMPTY CAN (SUPRASPINATUS) TEST

​• Test positioning

 

The client stands with both shoulders abducted to 90-degrees, horizontally adducted 30-degrees, and internally rotated so the client's thumbs face the floor.

 

​• Action

 

The therapist resists the client's attempts to actively forward elevate both shoulders.

 

​• Positive finding

 

Involvement of the supraspinatus muscle and/or tendon is suspected with noted weakness and/or a report of pain.

 

​• Special considerations & comments

 

Weakness of the supraspinatus muscle may be a result of suprascapular nerve involvement. 

 

Reported pain may be indicative of tendinitis and/or impingement.
