I. Introduction
IT is estimated that between 25–35% of people 65 years or older fall each year [1]. Although only a small percentage of those falls cause severe injury, a percentage that increases with age, falls among the elderly are a major health concern. Clinical research has indicated the importance of monitoring gait information for a number of medical applications [2]. Additionally, research has identified specific measures of gait which may be predictive of future falls in older adults [3]–[5]. However, the majority of older adults do not have their gait assessed on a regular basis.
