Execution
- 1Position the patient supine with the test arm forward flexed to approximately 30°.
- 2Place the heel of the hand over the coracoid process.
- 3Push the coracoid posteriorly toward the table to retract the scapula.
- 4Assess tissue stretch, discomfort, and whether the scapula lies flat.
- 5Measure the distance from the table to the posterior border of the acromion in relaxed supine.
Positive outcome
Tightness or muscular stretch over pectoralis minor during posterior movement is positive. Magee also notes that when pectoralis minor length is normal, the distance from the table to the posterior acromion should not exceed 2.54 cm, or 1 inch.
CommentPectoralis minor tightness can contribute to scapular protraction and altered shoulder elevation mechanics, but this is not a diagnostic test for rotator cuff tear. Measurement technique and patient posture can strongly influence results. Use it as an impairment measure and reassessment marker.
