Different feedback modes such as auditory, visual and haptic have been used in the past for gait retraining or learning movement patterns. The primary goal of this study was to investigate whether real time auditory feedback would be effective in children learning novel, dance-based movement patterns. For this purpose, a prototype wearable sensor was developed to provide auditory feedback whenever a child touches their heel to the ground.
To test the effectiveness of the auditory feedback in learning new patterns, typically developing children were taught simple Indian dance protocols consisting of four counts of foot-work which involved alternating heel-toe movements. The effect of wearing the sensor was assessed by the maximum vertical force with which the subjects struck their foot on the plate.
Auditory feedback reduced the learning time and increased the number of correct movement patterns for trial duration of 2 min. The prototype device did not alter the maximum force with which the subject placed the foot on the ground.
Real time auditory feedback can be reliably used to learn novel movement patterns.
过去曾使用不同的反馈模式，如听觉、视觉和触觉，来进行步态再训练或学习运动模式。本研究的主要目的是研究实时听觉反馈是否能有效帮助儿童学习新颖的、基于舞蹈的运动模式。为此，开发了一种原型可穿戴传感器，以便在儿童触地时通过听觉反馈。
为了测试听觉反馈在学习新图案方面的有效性，让正常发育的儿童学习由四个节拍组成的简单印度舞蹈方案，其中涉及交替脚跟到脚趾的动作。通过受试者脚撞击板的最大垂直力来评估佩戴传感器的效果。
听觉反馈减少了学习时间，并增加了正确运动模式的数量，试验持续时间为 2 分钟。原型设备并未改变受试者将脚放在地面上的最大力。
实时听觉反馈可用于可靠地学习新的运动模式。
