title: Efficacy of an Exercise Game Based on Kinect in Improving Physical Performances of Fall Risk Factors in Community-Dwelling Older Adults.
abstract: OBJECTIVE
  The purpose of this study was to demonstrate whether a 12-week program of training with dual-task Tai Chi (DTTC), which is a new concept game we developed using Kinect (Microsoft, Redmond, WA), would be effective in improving physical functions of fall risk factors.
  
  
  METHODS
  This study examined balance, muscle strength, locomotive ability, and dual-task ability in community-dwelling older adults (75.4±6.3 years) before and after 12 weeks of DTTC training (training group [TG]; n=32) or standardized training (control group [CG]; n=41). Primary end points were based on the difference in physical functions between the TG and the CG.
  
  
  RESULTS
  Significant differences were observed between the two groups with significant group×time interaction for the following physical function measures: timed up-and-go (TUG) (P<0.01), one-leg standing (OLS) (P<0.05), and 5 chair stand (5-CS) (P<0.05). There were no significant differences among the other measures: 10-m walking time under standard conditions, manual-task conditions, and cognitive-task conditions, 10-m maximal walking time, and Functional Reach test scores. Thus, the scores of TUG, OLS, and 5-CS in the TG improved significantly with DTTC training compared with the CG.
  
  
  CONCLUSIONS
  The results suggest that the DTTC training is effective in improving balance ability and mobility, which are risk factors for falls.
