Abstract

This study investigated the effects of visual feedback (VF) complexity on movement performance to potentially optimize the design of VF-based rehabilitation. We evaluated the effects of VF complexity on performance of the two-legged squat during training with concurrent (real-time) VF and short-term retention with no VF. Four VF cases were employed to train spatial positioning of the thigh segment in unique combinations of complexity (simple, complex) and representation of body-discernibility (abstract, representative). Eighteen able-bodied subjects attempted to minimize the error between individual body segment positions and a target trajectory during concurrent VF and short-term retention tests. Complex-representative VF demonstrated greater potential for training with increased performance consistency in both motion and muscle activity patterns.

视觉反馈复杂度对康复运动任务执行的影响。

摘要

这项研究调查了视觉反馈(VF)复杂性对运动表现的影响,以潜在地优化基于VF的康复设计。我们评估了在同时(实时)VF训练和没有VF的短期保留的训练过程中,VF复杂度对两足下蹲性能的影响。使用四个VF案例以复杂性(简单,复杂)和身体可分辨性表示(抽象,代表性)的独特组合来训练大腿段的空间定位。在同时进行的VF和短期保留测试中,有18名身体强健的受试者试图将各个身体部位的位置和目标轨迹之间的误差减至最小。具有复合体代表性的VF在运动和肌肉活动模式上表现出更高的表现一致性,具有更大的训练潜力。
