Abstract

The excitability curve of the H reflex conditioned by stimulation of a mixed nerve was studied in eight Parkinsonism patients, before and after L-dopa therapy. There was no significant variation between the two curves. However, there was a reduction of the normal early inhibition of the H reflex conditioned by exteroceptive stimulation. This indicates the presence of alterations in the organisation of the reflex pathways at a spinal level in this disease.

摘要

在八名帕金森病患者中,研究了左旋多巴治疗前后由混合神经刺激所诱发的H反射的兴奋性曲线。两条曲线之间无显著差异。然而,由外感受性刺激所诱发的H反射的正常早期抑制作用减弱。这表明在该疾病中脊髓水平的反射通路组织存在改变。
