Abstract

Individuals with chronic ankle instability (CAI) have deficits in postural control. Previous studies assessing postural control have been limited by minimal environmental perturbation. Little is known about adding dynamic environments using virtual reality (VR) during static postural control in individuals with CAI. PURPOSE: To identify the effects of VR-based assessment on static postural control among individuals with CAI, copers, and healthy controls. METHODS: A total of 60 participants, including 20 individuals with CAI, 20 copers, and 20 healthy controls, performed 3 trials of a single-leg stance for 10 seconds with eyes open (EO), closed (EC), and VR. During the single-leg stances, participants were instructed to stand as still as possible on a force plate (1000Hz, AMTI, Watertown, MA) with hands crossed on the chest, holding the opposite leg at approximately 45° of knee flexion and 20° of hip flexion. First investigator provided participants with VR gear (Facebook Technologies LLC, Menlo Park, CA, USA) with a Samsung S8 phone (Samsung Electronics, Suwon, South Korea) and explained how the VR functioned. Second, the investigator provided all participants with a cue to commence the single-leg stance upon commencement of the VR video. The VR video was remotely controlled via a computer to show 360° landscape video. Static postural control was analyzed by two-way ANOVA (3 groups x 3 visual conditions) for group x condition interaction. RESULTS: : Individuals with CAI showed less static postural control in the COP ML range and area under VR than copers and healthy controls. Copers showed better static postural control in the COP ML range and in the area under VR and EC than individuals with CAI and healthy controls. Both VR and EC resulted in worse static postural control than EO across the three groups. However, there were no differences between VR and EC during static postural control across the three groups. CONCLUSION: Individuals with CAI demonstrated less static postural control under VR than copers and healthy controls, whereas copers exhibited better postural stability under VR than individuals with CAI and healthy controls. Therefore, VR may offer a new assessment to evaluate postural control and better understand neural processing in individuals with CAI and copers.
