Insole-Shaped Pneumatic Feedback for Directional Weight-Shifting Guidance

In this publication, researchers developed an innovative insole-shaped pneumatic feedback device to provide directional weight-shifting guidance. To evaluate the device's efficacy, Moticon OpenGo sensor insoles were deployed at a 50Hz sampling rate to capture plantar pressure data directly from the participants' feet. The Moticon sensor insoles were instrumental in measuring precise objective variables, specifically the center of pressure (CoP) displacement and circular direction before and after feedback delivery. These measurements directly influenced the study's conclusions by providing the empirical validation necessary to prove that the pneumatic device successfully induced targeted CoP displacements, demonstrating particular effectiveness in forward and backward directions.
