Multiple motion gaming devices based balance evaluation platform

Abstract

The purpose of this study was to introduce a balance evaluation system using multiple motion gaming devices and verify its reliability and feasibility in the clinical setting. This research collected data from 12 (4 males, 8 females) healthy participants without neurological or musculoskeletal impairment (21.58 ± 1.44 years, 168.25 ± 8.66 cm, 61.67 ± 16.01 kg) and the participants performed balance tests on the Wii Balance Board, in front of the Kinect. The present study analyzed the total path distance of the center of pressure (COP), the area of COP displacement, and the number of postural error while maintaining static position for 20 seconds. Six different conditions consisted of double leg stance (DLS), singledominant leg stance (SDLS), and single-nondominant leg stance (SNLS) with both eyes open (EO) or closed (EC). Correlation analyses and repeated-measures ANOVAs with post-hoc tests were implemented by using SPSS 23 and the statistical significance level was set with α=0.05. The result of analysis related to the reliability of the system is from r=.173 to r=.917. COP (path distance, area) was significantly higher for each stance with EC than with EO, except the COP area between DLS conditions. There were no significant difference between SDLS-EO and SNLS-EO and between SDLS-EC and SNLS-EC. In the future, this system could be a new balance assessment tool in the clinical setting. © 2017 SPIE.
