Effects of Various Smart Device on Postural Control

Abstract

The purpose of this study was examine the effects of performing dual task while using a smart device (smart watch, smart phone, and smart pad) on static and dynamic postural stability.Methods/Statistical analysis: Thirty-six subjects were asked to stand on a force plate and then instructed to perform a balance task while talking on the mobile phone, balance task while sending text massage, and balance task while playing game. We used the BioResue to measure postural sway for static postural stability and Y-balance test was used to measure dynamic postural stability. A one- way ANOVA with repeated measures was used. Findings: In static postural stability, smart watch was significantly decreased than smart phone and smart pad during game task and conversation task. In dynamic stability, smart watch was significantly decreased than smart pad and smart during game task. Improvements/Applications: This finding suggest that performing dual task using smart watch decreased static and dynamic stability compare with smart pad and smart phone. Therefore, it requires more attention to maintain static and dynamic balance while using smart watch.
