In 143 normal subjects latencies of H-reflexes of the flexor carpi radialis muscle were well correlated with arm lengths. In 32 patients with injury to cervical roots C5 to C8 it was shown that latencies were only abnormal in lesions of roots C6 or C7. It is suggested that in most instances root C6 or C7 and, probably both roots in some cases are involved in the reflex pathway. Repeat electrophysiological examinations after surgery provided valuable data about the various types of nerve root recovery.
在143名正常受试者中，桡侧腕屈肌H反射的潜伏期与手臂长度密切相关。在32例颈5至颈8神经根损伤患者中，发现只有颈6或颈7神经根损伤时潜伏期才会异常。提示在大多数情况下，颈6或颈7神经根，在某些情况下可能是两根神经根均参与了反射通路。术后重复进行电生理检查提供了有关各种类型神经根恢复的有价值数据。
