Clinical and electrophysiological assessment of recovery of function are reported on 20 patients with median or ulnar nerve sections up to 53 months after surgical repair. Maximum improvement of sensory function was apparent by both methods of assessment at 15 months after suture, and thereafter conduction velocities in sensory fibres averaged 80% of normal in median nerves and 70% of normal in ulnar nerves. Similarly, the mean amplitude of the sensory action potential at the wrist remained depressed at 15% of control values. The clinical recovery of motor function pursued a similar time course with, however, some evidence to indicate a continuing improvement in the neurophysiological maturation of the motor nerve fibres up to 47 months after repair. The results are discussed in relation to previous electrophysiological studies on animals.
报告了20例正中神经或尺神经切断术后接受手术修复长达53个月的患者功能恢复的临床和电生理评估情况。缝合后15个月，两种评估方法均显示感觉功能有最大程度的改善，此后正中神经感觉纤维的传导速度平均为正常的80%，尺神经为正常的70%。同样，腕部感觉动作电位的平均波幅仍维持在对照值的15%。运动功能的临床恢复遵循类似的时间进程，不过有证据表明，直至修复后47个月运动神经纤维的神经生理成熟仍在持续改善。结合先前对动物的电生理研究对结果进行了讨论。
