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.
六名排球运动员优势侧的冈下肌出现无力和萎缩。肌电图（EMG）显示神经支配缺失和运动单位丧失，且仅限于冈下肌，冈上肌和其他肩部肌肉保持正常。冈下肌神经病变可能是排球运动员的职业危害。提示肩胛上神经在肩胛冈盂切迹处有损伤。
