empty can test

(redirected from Supraspinatus Test)
A clinical test used to identify injury/pathology of the supraspinatus and said to isolate supraspinatus muscle activity from that of other rotator cuff muscles

empty can test

An orthopedic test of the shoulder, used to determine the integrity of the supraspinatus muscle. With the patient sitting or standing, the shoulder is fully internally rotated, abducted to 90 degrees, and placed in 30 degrees of forward flexion, as if emptying a beverage can. The patient then attempts to maintain this position against resistance. Inability to hold this position, or pain while holding it, suggests pathology of the supraspinatus muscle.

The empty can test, also known as the supraspinatus test or Jobe test (resisted shoulder abduction in internal rotation), demonstrated diagnostic accuracy only once in 21 evaluations across six studies (Holtby and Razmjou 2004, Itoi et al 1999, Itoi et al 2006, Kim et al 2006, Leroux et al 1995, Park et al 2005).
