Responses evoked by an electrical stimulus to the median nerve in a small muscle of the human hand during a voluntary contraction have been examined. Two of these responses have been shown to be evoked through reflex pathways. The first, with a mean afferent conduction velocity of 64 m/s and estimated central delay of about 0.8 ms, is identified as an H reflex. The second response, which has an undefined central pathway, has a mean afferent conduction velocity of 43 m/s and an estimated central delay of about 17 ms.
对人手中一块小肌肉在自主收缩期间由正中神经电刺激诱发的反应进行了研究。已表明这些反应中有两种是通过反射通路诱发的。第一种反应，平均传入传导速度为64米/秒，估计中枢延迟约为0.8毫秒，被确定为H反射。第二种反应，其中枢通路不明确，平均传入传导速度为43米/秒，估计中枢延迟约为17毫秒。
