Motoneuron pool excitability of the hemiplegic patients assessed by new methord H-reflex and M-response

用H反射和M反应相结合的新方法，即测定H反射与M反应的发育斜率之比(Hslp/Mslp)，比较偏瘫患者痉挛侧和健侧运动神经元池的兴奋性。此外，根据Brunnstrom分级，恢复阶段之间也有关系，这表明脑损伤后的痉挛程度与双侧痉挛的运动神经元池兴奋性有关。HSLP/MSLP较传统的运动神经元兴奋性指标具有更好的预测价值。此外，HSLP/MSLP也很好地对应于Brunnstrom阶段。这些结果表明，HSLP/MSLP在评估运动神经元池的兴奋性方面具有较好的实用性，这是康复临床领域中一个长期存在且仍未澄清的问题。

The excitability of the motoneuron pools of both the spastic side and normal side of hemiplegic patients was compared using a new method employing H-reflexes and M-responses, i.e., by determination of the ratio of the developmental slope of the H-reflex to that of the M-response(Hslp/Mslp). Also, a relationship was found between the recovery stages, as assessed by the Brunnstrom stage, which shows the degree of the spasticity after brain lesion and the motoneuron pool excitability of both spastic sides. Hslp/Mslp was found to have better predictive value than the conventional indicators of motoneuron pool excitability. Further, Hslp/Mslp also corresponded well to the Brunnstrom stage. These results suggest the superior usefulness of Hslp/Mslp for evaluation of the motoneuron pool excitability, which is a long-standing and still unclarified problem in the clinical field of rehabilitation.
