Evidence for a point of no return in a motor act has been reported to occur very late in its preparation and even to the point at which the response is executed. We report a qualitative example from electromyographic (EMG) data of an elbow-extension movement from 1 of 12 adults which suggests that the response can be stopped at any time up to its production, from which we conclude that the response is subject to on-line control at all times.
据报道，运动行为中不可逆转点的证据在其准备阶段非常晚才出现，甚至到了反应执行的阶段。我们从12名成年人中的1名进行肘部伸展运动的肌电图（EMG）数据中给出了一个定性示例，这表明在反应产生之前的任何时候都可以停止反应，由此我们得出结论，反应在任何时候都受到在线控制。
