在运动训练和神经康复中，有许多例子表明，通过使用增强的视觉反馈进行练习，可以操纵平均表现。我们的目标不仅仅是影响平均值，而是使用一种称为极限推动的新反馈技术，通过扭曲视觉来影响运动的试验间变异性。限制推动以前是使用机器人的力量，本研究只采用视觉扭曲，模仿限制推动的方法。像机器人力治疗一样，我们的结果显示了受试者如何显着改变他们的运动分布。这种效果甚至比最初使用机器人力量的极限推动实验还要大。这种视觉失真干预不需要机器人进行增强训练。视觉极限推动技术似乎能够选择性地改变表演训练应用中的集中趋势和变异性。
In both movement training and neurorehabilitation, there have been numerous examples of how average performance can be manipulated through practice using enhanced visual feedback. Rather than just influencing the mean, our objective was to use a novel feedback technique called limit-push to influence the trial-to-trial variability of motion by distorting vision. Limit-push was previously done using robotic forces; the present study employed only visual distortions that imitated the limit-push approach. Like the robotic force treatment, our results showed how subjects significantly shifted the distributions of their motions. This effect was even greater than that of the original limit-push experiment that used robotic forces. Such visual distortion interventions do not require a robot for enhanced training. The visual limit-push technique appears to be able to selectively alter both the central tendency and variability in performance training applications.
