INTRODUCTION The feasibility of intensive physical exercise in the rehabilitation of elderly institutionalised patients can be reduced by fatigue or lack of interest. Low-volume exercise interventions with similar training effects might be an alternative. The aim of this randomised controlled trial was to investigate the feasibility of Whole Body Vibration (WBV) in institutionalised elderly, and its impact on functional capacity and muscle performance. METHODS Twenty-four nursing home residents (mean age 77.5 years SD=11.0; 15 female, 9 male) were randomised to 6 weeks static WBV exercise (WBV+, N=13) or static exercise only (control, N=11). Outcome measures were exercise compliance, timed up-and-go, Tinetti-test, chair sit-and-reach, back scratch, handgrip strength and linear isokinetic leg extension. RESULTS At baseline, WBV+ and control groups were similar for all outcome variables. Twenty-one participants completed the program and attended respectively 96% and 86% of the exercise sessions for the WBV+ and control groups. Training-induced changes on timed up-and-go and Tinetti scores were better for WBV+ compared to control (p=0.029 for timed up-and-go and p=0.002 for Tinetti-score respectively). No other significant differences in change between both groups were observed. CONCLUSIONS Six weeks static WBV exercise is feasible, and is beneficial for balance and mobility in institutionalised elderly. The supplementary benefit of WBV on muscle performance compared to classic exercise remains to be explored further.
