Seven normal subjects were instructed to adduct the arm as fast as possible. On some trials the movement was prevented mechanically. For each movement or attempted movement, the EMG response in the antagonist muscle was measured. On trials in which no movement occurred, the respones were significantly smaller than those obtained during free, ballistic movement. The results demonstrate the role of proprioceptive influences on the contraction of the antagonist muscle.
七名正常受试者被要求尽快内收手臂。在一些试验中,动作被机械阻止。对于每次动作或尝试的动作,测量拮抗肌的肌电图反应。在没有动作发生的试验中,反应明显小于自由弹道式动作时获得的反应。结果证明了本体感受对拮抗肌收缩的影响作用。
