Ulnar neuropathy at the elbow is a common disorder seen in the throwing athlete. The purpose of our study was to determine whether asymptomatic physically active volleyball players and non-actives demonstrate distinct differences in nerve conduction of the ulnar nerve at the elbow. Nerve conduction studies were performed on both arms of 24 male volleyball players and 24 male non-actives. Nerve conduction velocity at the above to below elbow segment of the ulnar motor nerve were slower in the volleyball players compared with controls and their non-dominant arms. There were no statistical differences in latencies and conduction velocity of the ulnar nerve on the forearm, both in volleyball players and in the controls. In the evoked responses of the ulnar nerve, the amplitude was the same as corresponding normal values in both sensory nerve and muscle action potentials. We conclude that abnormal ulnar (motor) nerve conduction at the elbow segment may suggest a subclinical entrapment neuropathy as a result of strenuous elbow movements in volleyball players.
肘部尺神经病变是投掷运动员中常见的一种疾病。我们研究的目的是确定无症状的从事体育活动的排球运动员与不从事体育活动的人在肘部尺神经传导方面是否存在明显差异。对24名男性排球运动员和24名男性非运动员的双臂进行了神经传导研究。与对照组及其非优势手臂相比，排球运动员尺神经在肘部以上至以下节段的神经传导速度较慢。排球运动员和对照组在前臂尺神经的潜伏期和传导速度方面均无统计学差异。在尺神经的诱发反应中，感觉神经动作电位和肌肉动作电位的幅度均与相应的正常值相同。我们得出结论，肘部节段尺（运动）神经传导异常可能提示排球运动员因肘部剧烈运动导致亚临床卡压性神经病变。
