In this study, the exercise program was designed based on considerations of postural balance and lower-limb muscle strength as factors for fall prevention. In particular, postural balance is closely correlated with fall risk. Here, static balance was assessed using AP postural sway velocity, ML postural sway velocity, and velocity moment as measured using a force platform. Postural sway is known to be greater in elderly individuals than in young adults and has been demonstrated to be greater in elderly individuals who have experienced a fall than in those who have not (Tinetti 2003; Lajoie 2004).
