title: Suprascapular neuropathy restricted to the infraspinatus muscle in volleyball players.
abstract: Six volleyball players developed weakness and atrophy of the infraspinatus muscle on the dominant side. Electromyography (EMG) disclosed denervation and motor unit loss restricted to the infraspinatus muscle, the supraspinatus and other shoulder muscles remaining normal. Infraspinatus neuropathy may occur as a professional hazard in volleyball players. A lesion of the suprascapular nerve at the spinoglenoid notch is implied.
