Boettcher CE, Ginn KA and Cathers I (2009): The 'empty can' and 'full can' tests do not selectively activate supraspinatus. Journal of Science and Medicine in Sport 12: 435-439. (Abstract prepared by Angela Cadogan) Background: Based on previous electromyographic (EMG) studies the 'Empty Can' (EC) and 'Full Can' (FC) tests have been promoted as being able to isolate activity to supraspinatus. On this basis, the FC and EC tests have been reported as being diagnostic of supraspinatus dysfunction. However, there is evidence to suggest that these positions do not selectively activate supraspinatus, bringing into question the anatomic validity of these tests. This has implications for their use both as a diagnostic tool and as isolated strengthening exercises.
