The examiner stands level with the subject’s arm. He places one hand on the opposite shoulder and the other hand against the outer and distal aspect of the forearm, which he supports.

Common mistakes

The subject tends to execute the test wrongly either by bringing the shoulder into abduction or by extending the elbow, especially when weakness is present.

Anatomical structures tested:

Muscle function:

  1. Important external rotators:
    • Infraspinatus
    • Teres minor
  2. Less important external rotators:
    • Spinal part of deltoid.

Common pathological situations:

  • Pain occurs in infraspinatus tendinitis but may also be present in subdeltoid bursitis.
  • Weakness indicates a total rupture of the infraspinatus tendon or a neurological condition, e.g. C5 nerve root palsy, suprascapular nerve palsy, neuralgic amyotrophy. Bilateral weakness is suggestive of myopathy.
  • Painful weakness is the result of a partial rupture of the infraspinatus tendon.
