Abstract

Falls among the elderly are quickly becoming an enormous concern in every society given the projected increase in the 65-plus age group. Elderly falls can be mainly attributed to decreased lower extremity strength and reducing the potential for elderly falls requires regular exercise. Therefore the purpose of this study was to investigate whether a 24-week walking exercise would reduce elderly fall risk factors. Twenty-two community-dwelling female elderly were randomized to either a control(CG, n=11) or experimental group(EG, n=11). The EG performed a walking exercise(3 times/week, 1 hour/visit) for 24 weeks. Laboratory kinematics during stepping over(SOG), stepping up(SUG), and stepping down(SDG) an obstacle was assessed at weeks 0 and 24. Significant obstacle traverse such as maximum vertical heel clearance(MVHC), toe and heel clearance(TC & HC), vertical descending velocity(VDV), and limb flexion resulted in an improved crossing strategy in EG. These findings provide evidence of significant reduced fall risk factors of community-living older adults associated with a systematic walking program.
