The effect of wearing the customized insole on the coordination of the right and left wrists measured by wearables during golf swing

Abstract

The purpose of this study was to investigate the effect of the presence or absence of the insole on the intra—limb coordination between right and left wrists measured by IMU wearables. The subjects were one male and one male with foot deformity. The IMU-based wearables (CUBE MOTION, K2155~58, MSIP-CRM-sed-CM-IMUI-T) sampling rate was 800 Hz/s. The customized insole was constructed to raise the inner arch so that the RCSP would be in neutral position. The custom foot corrective insole influenced the proximal wrist movement during the golf swing. It was also effective in correcting the golf performance and as a result increasing the distance and reducing the angle of flight. Therefore, the acceleration-based IMU can conclude that it is a reliable and valid tool for kinematic analysis. This study will contribute to provide a basis for evaluating the validity of kinematic analysis using IMU wearables as well as identifying the effects of customized insole on golf performance. © 2019, Springer Nature Singapore Pte Ltd.
