Purpose[edit | edit source]
The Full Can Test is used to assess the function of Supraspinatus muscle and tendon.
Technique[edit | edit source]
The patient can be seated or standed for this test holding the arm in 90°elevation in scapular plane (30° anterior to the frontal plane) with full external rotation. In this position, the thumb should be pointing up.The therapist should stabilize the shoulder while applying an upward force to the arm whilst the patient tries to resist this motion. This test is considered positive if the patient experiences pain or weakness with resistance.[1]
Evidence[edit | edit source]
Kelly et al. reported that the full-can test for assessment of supraspinatus function which had similar electromyographic (EMG) activity compared with the empty-can test, but that it provoked less pain. Their findings showed no significant difference in supraspinatus muscle activation with variation in humeral rotation. There is slightly less activation of the infraspinatus muscle leading to a better isolation of the muscle. [3] It is also suggested that in this testing position, there is less activity of surrounding muscles such as deltoid and subscapularis.[4]
