摘要

在视觉遮挡的等距任务中，指尖力的减少被称为无意漂移。在这项研究中，无意漂移研究了两种情况，有和没有“后记”。我们将尾声定义为试验后的视觉反馈，即在下一次试验开始之前显示刚刚结束的试验的结果。在这项研究中，招募了14名健康的参与者，并指示他们在15%的最大自愿收缩时产生与目标线匹配的指尖力量。结果显示，在后患条件下无意漂移显著减少。这种减少可能是由于强直性拉伸反射的阈值λ的位移不同，这是中央控制器可以设置的假设控制变量。

Role of Post-Trial Visual Feedback on Unintentional Force Drift During Isometric Finger Force Production Tasks.

A reduction in fingertip forces during a visually occluded isometric task is called unintentional drift. In this study, unintentional drift was studied for two conditions, with and without "epilogue." We define epilogue as the posttrial visual feedback in which the outcome of the just-concluded trial is shown before the start of the next trial. For this study, 14 healthy participants were recruited and were instructed to produce fingertip forces to match a target line at 15% maximum voluntary contraction. The results showed a significant reduction in unintentional drift in the epilogue condition. This reduction is probably due to the difference in the shift in λ, the threshold of the tonic stretch reflex, the hypothetical control variable that the central controller can set.

期刊介绍： Motor Control (MC), a peer-reviewed journal, provides a multidisciplinary examination of human movement across the lifespan. To keep you abreast of current developments in the field of motor control, it offers timely coverage of important topics, including issues related to motor disorders. This international journal publishes many types of research papers, from clinical experimental to modeling and theoretical studies. These papers come from such varied disciplines as biomechanics, kinesiology, neurophysiology, neuroscience, psychology, physical medicine, and rehabilitation. Motor Control, the official journal of the International Society of Motor Control, is designed to provide a multidisciplinary forum for the exchange of scientific information on the control of human movement across the lifespan, including issues related to motor disorders. Motor Control encourages submission of papers from a variety of disciplines including, but not limited to, biomechanics, kinesiology, neurophysiology, neuroscience, psychology, physical medicine, and rehabilitation. This peer-reviewed journal publishes a wide variety of types of research papers including clinical experimental, modeling, and theoretical studies. To be considered for publication, papers should clearly demonstrate a contribution to the understanding of control of movement. In addition to publishing research papers, Motor Control publishes review articles, quick communications, commentaries, target articles, and book reviews. When warranted, an entire issue may be devoted to a specific topic within the area of motor control.
