Measurement of motion range to improve of body balance and its training contents

Abstract

Wrong lifestyle habits can be a major factor for reduced balance ability that may cause difficulties in performing daily activities due to musculoskeletal disorders, gait abnormality, a fall, and other problems. This study assessed range of motion (ROM) using Inertial Measurement Unit (IMU) sensors placed at the waist or upper and lower limbs by measuring the maximum rotation angle of the body to the directions of the sagittal, coronal and transverse planes in real time. Directions with a low body balance are identified using ROM data and based on the analysis results, training content is recommended to improve reduced balance ability in corresponding directions. Furthermore, this content is designed to offer intensive balance training toward a specific direction by providing selection modes of balance training in the desired directions. Motivation for training can be enhanced by comparing changes in measurements assessed before and after balance training. The results of this study are expected to aid improving reduced physical activities in elderly individuals with reduced muscle strength, body balance and walking ability using the content tailored to measure changes in range of motion and improve balance ability.
