The parameters of the motor and the central responses of the thenar muscles to stimulation of the median nerve in 28 healthy subjects and 85 neurological patients were examined. It was shown that the infracervical alpha-motoneurons responded only to antidromic stimulation (the F-wave was registered). In cerebral pareses monosynaptic transmission from the 1a afferents becomes possible (the central response is similar to the H-reflex): this points to a disturbance of the segmented inhibition. In processes involving the anterior corticospinal tract the F-wave is depressed down to its complete disappearance, i.e. the motoneurons lose their capacity to respond to antidromic stimulation.
对28名健康受试者和85名神经疾病患者的运动参数以及正中神经刺激时鱼际肌的中枢反应进行了检查。结果显示，颈下α运动神经元仅对逆行刺激有反应（记录到F波）。在大脑性麻痹中，来自Ia传入纤维的单突触传递成为可能（中枢反应类似于H反射）：这表明节段性抑制受到干扰。在前皮质脊髓束受累的过程中，F波降低直至完全消失，即运动神经元失去对逆行刺激的反应能力。
