Reducing falls risk with Kinect based falls prevention EXERGAMES: a 12 week twocentre, cluster RCT of community-dwelling older adults living in sheltered housing

Abstract

Introduction: Falls are the leading cause of fatal and non-fatal unintentional injuries in older people. Despite overwhelming evidence for strength/balance training, adherence to both group and home-exercise programmes is often poor1. A novel approach is the use of home-based, strength and balance video-games (EXERGAMES) but data from randomized controlled trials are limited2. The aim of this study was to test whether a 12 week EXERGAMES home-based intervention, co-developed with older adults and therapists, can improve the risk of falling [by Berg Balance Scale (BBS)] in older adults living in sheltered housing.

Methods: We conducted a two-site (Manchester/Glasgow) cluster RCT. Twelve sheltered housing facilities were randomised (1:1) to either a 12wk standard care plus 3 times/ week EXERGAMES physiotherapist one-to-one intervention (n=56) or standard care (control group n=50). Standard care involved the provision of a home exercise booklet (standard approach for those unable/unwilling to attend group exercise programmes in the community). Results: A total of 106 older adults (83F, 23M) with a mean age of 77.8y (SD 10.2; range 55-101y), were recruited for the study. A total of 91 (86%) participants completed all study visits. Over 12 weeks the EXERGAMES intervention had a significant positive impact on BBS [p=0.003; mean (SD), 44.6 (10.7) (EXERGAMES) vs. 37.6 (14.9) (Control)]. The mean change of BBS from baseline was 2.9 (8.5) for the EXERGAMES and -2.8 (6.5) for the control group. The estimated increase in BBS score due to EXERGAMES was 6.2 (95% CI 2.4 to 9.9) which is greater than the minimal detectable change for the scale of 4.93.

Conclusions: Balance, and thus risk of falling, can be improved through a 12wk physiotherapy led EXERGAMES programme. This type of home based intervention could be considered as an effective alternative to traditional falls prevention exercise regimes to support outcomes for patients.
