We studied reciprocal inhibition by recording the changes in firing probability of single motor units of the tibialis anterior muscle following stimulation of low-threshold afferents in the posterior tibial nerve. In 15 patients with cerebral palsy, the inhibition was as great or greater than normal. We found no evidence that group I afferents produce "reciprocal facilitation" in cerebral palsy.
我们通过记录胫后神经低阈值传入纤维受刺激后胫骨前肌单个运动单位放电概率的变化来研究交互抑制。在15例脑瘫患者中,这种抑制作用与正常人相同或更强。我们没有发现证据表明I类传入纤维在脑瘫中产生“交互易化”。
