Modulation of the human soleus H-reflex (Sol, H-R) was studied during voluntary teeth clenching in 11 healthy adult volunteers, to investigate the possible correlation of motor functions between the jaw and body.The following results were obtained ;(1) Sol. H-R was facilitated during the maximum voluntary teeth clenching. The facilitation exceeded that during the maximum voluntary efforts in the other parts of the body, i. e., Jendrassik maneuver and bilateral fists clenching.(2) The amount of the Sol. H-R facilitation increased with the amplitude of masseter EMG activity,(3) Facilitation of the Sol. H-R in association with teeth clenching started ca. 60ms before the-onset of masseter EMG activity, reached its peak ca. ]100ms after the onset and thereafter decreased to a certain plateau level in accordance with the masseter EMG activity level.(4) Facilitation of the So] : H-R during teeth clenching was decreased when the masseter EM(3 activity was reflexively inhibited by electrical stimulation of the lower lip, though the facilitation was still retained.It was concluded that]) the excitability of the Sol. H-R is remarkably elevated during teeth clenching. 2) there is a positive correlation between the amount of the facilitation of the Sol. H-Rand the teeth clenching force level, and 3) the facilitation is due to both the descending influence from the higher brain and the afferent inputs from the oral structures.It is assumed that the oral motor activity exerts a strong influence on the body motor function in general,

本文研究了11名健康成年志愿者咬牙时人体比目鱼肌H-反射(SOL，H-R)的调制，以探讨颌骨和身体运动功能的可能相关性。在最大程度自愿咬合的过程中，H-R被促进。这种促进作用超过了身体其他部位的最大自愿努力，即Jendrassik动作和握拳。(2)SOL量。H-R易化性随咬肌肌电活动幅度的增加而增加，(3)SOL易化性。与咬合有关的H-R在咬肌肌电活动开始前约60ms开始，起病后约100ms达到高峰，之后根据咬肌肌电活动水平降至某一平台水平。(4)咬合时SO]：H-R的易化性在咬合肌EM时降低(电刺激下嘴唇反射性地抑制了H-R活动，但易化性仍保持不变。咬合时H-R显著升高。(2)SOL易化量与SOL易化量呈正相关。H-Rand和牙齿咬合力水平，3)易化是由于来自高级大脑的下行影响和来自口腔结构的传入输入。假设口腔运动活动总体上对身体运动功能产生强烈的影响，
