The aim of this investigation was to re-establish the nature of the involvement of the peripheral nervous system after lesions of the central nervous system. An examination of 120 patients with spastic hemiparesis after stroke was performed. The motor conduction velocities, M-response latencies and amplitudes, as well as F-wave latencies were evaluated in median, ulnar, peroneal and tibial nerves. The minimal latency of soleus H-reflex was obtained. Our results revealed normal motor conduction velocities, and distal M-response and H-reflex latencies on the involved side. However the amplitudes of the M-responses were decreased and the latencies of the F-waves prolonged on the spastic side. In conclusion primary axonal degeneration with secondary segmental demyelination, involving predominantly proximal parts of the peripheral nerves, occurs after central nervous system injury.
本研究的目的是重新确定中枢神经系统损伤后周围神经系统受累的性质。对120例中风后痉挛性偏瘫患者进行了检查。评估了正中神经、尺神经、腓总神经和胫神经的运动传导速度、M波反应潜伏期和波幅以及F波潜伏期。获得了比目鱼肌H反射的最短潜伏期。我们的结果显示，患侧运动传导速度、远端M波反应和H反射潜伏期正常。然而，痉挛侧M波反应的波幅降低，F波潜伏期延长。总之，中枢神经系统损伤后会发生原发性轴索变性伴继发性节段性脱髓鞘，主要累及周围神经的近端部分。
