Improving gait characteristics in older adults: The effects of Biodex Balance System SD™ and wobble board balance training

Abstract

Mobility, the ability to walk safely and independently, is an important component of everyday life that is dependent on adequate balance control (Shumway-Cook et al., 2002). Age-related declines in balance control lead to avoidance of activity, which ultimately further degrades the balance control system (Shumway-Cook & Woollacott, 2010). Exercise has been deemed the most important factor in improving balance in older adults (NIH, 2008). Training paradigms have been developed to improve balance control in older adults. It is important to compare training programs to determine their relative efficacy on improving gait. The overall objective of this study was to examine if balance training while standing would lead to improved gait. A second objective of the study was to determine the relative efficacy of training with a traditional wobble board versus the Biodex Balance System SD™. During wobble board training, the participant attempts to maintain balance while standing on an unstable platform. The Biodex provides visual feedback regarding the participants’ movements during weight-shifting tasks on an unstable platform. The intervention groups (wobble board, n=9; Biodex, n=9) trained three times per week for six weeks, while non-exercise control older adults (n=19) maintained their regular activities for six weeks. The variability of steady state gait improved with Biodex training, but did not improve with wobble board training. Improvements in gait speed during obstacle crossing were similar for both Biodex and wobble board training. These findings indicate that gait can be improved without specifically training gait. Overall, Biodex training was found to be superior to wobble board training for improving gait parameters.
