Effects of balance training incorporating with a kinect-based exergame on mediolateral postural sway in older adults with balance impairment: A pilot study
Abstract
Background: Older adults with balance impairment have reduced lateral balance control in dual task situations. Previous study showed that a virtual reality training intervention such as Kinect-based game exercise can improve balance and cognitive function, however, there has no reports focused on the effect of a Kinect-based game exercise on dual task balance performance. Objectives: To investigate the effect of balance training with additional Kinect-based game exercise intervention on mediolateral postural sway, while performing dual tasks, in older adults with balance impairment. Materials and methods: Ten older adults with balance impairment, were recruited from community. They were divided into two groups; control group received conventional balance training, experimental group received conventional balance training together with Kinect-based game exercise training. Both groups had 4 sessions of exercise, 45 minutes each, and twice a week for 2 weeks. Mediolateral sway data were collected while performing a verbal place naming task at pre- and post-training using Wii Balance Board with MFU static balance test software, under 4 different conditions including semi-tandem standing with eyes closed and eyes open, and feet together with eyes closed and eyes open. All data were compared between groups and within group using Mann Whitney U test and Wilcoxon signed-rank test by STATA software. Results: The results showed no significant decrease in mediolateral postural sway and no increase in number of correct answers in all conditions after training both between groups and within group. Conclusion: Balance training with additional Kinect-based game exercise, for a total of 3 hours, twice a week for 2 weeks has no effect on mediolateral postural sway while performing dual tasks in older adults with balance impairment.
