Suprascapular neuropathy in volleyball players

Abstract

We examined ninety-six top-level volleyball players from eight teams that competed during the 1985 European Championships, and twelve players were found to have asymptomatic isolated paralysis of the infraspinatus of the dominant side. Three players were studied with electromyography and Cybex-II isokinetic dynamometry. The results revealed denervation of the infraspinatus and approximately a 22 per cent loss of strength of the affected arm during external rotation. These findings were attributed to repeated stress due to stretching of the nerve during cocking of the arm and follow-through when the athlete was serving.
