Full Can Test
|
This test assesses for supraspinatus pathology.
|
Patient is seated or standing with arm raised in the scapular plane to 30-45 degrees (some authors suggest 90 degreed[1]) with shoulder externally rotated. The therapist applies a downward force just proximal to the patient’s wrist while the patient resists. Test is positive if it elicits pain and/or weakness.

Empty Can/ Supraspinatus Test
|
A positive test indicates a tear to the supraspinatus tendon or muscle and can also indicate a neuropathy of the suprascapular nerve.
|
The patient actively abducts the arm to 90 degrees with the thumbs up which makes the full can position. The examiner then provides downward pressure on the arm to test the patient’s strength. The patient then elevates the arms to 90 degrees and horizontally adducts 30 degrees to the scapular plane with thumbs down to the empty can position. The examiner provides downward pressure to test the patient’s strength in this position. A positive test for rotator cuff tear is more weakness in the empty can, patient complaint of pain, or both.
