H-reflex latency (H-RL) and H/M ratio were measured in normal children and children with paralytic poliomyelitis of 1-3 years of age. The H-RL was considerably increased in both the involved and uninvolved limbs of the patients, whereas the H/M ratio did not differ. The Mmax value in the involved limb was very low, and therefore, a corrected H/M ratio was calculated for that side only. The corrected H/M ratio was significantly less than the H/M ratio observed in the uninvolved and control limbs. The distal motor latency was also increased in the involved side.
在1 - 3岁的正常儿童和小儿麻痹症患儿中测量Hoffmann反射潜伏期（H - RL）和H/M比值。患者受累肢体和未受累肢体的H - RL均显著增加，而H/M比值无差异。受累肢体的最大肌肉反应（Mmax）值非常低，因此仅针对该侧计算校正后的H/M比值。校正后的H/M比值显著低于未受累肢体和对照肢体的H/M比值。受累侧的远端运动潜伏期也增加。
