An analysis of dynamic gait stability between young and elderly population using zero moment point method

A stability of the elderly population is considered as a major factor for fall risk assessment. A dynamic stability of the elderly population has not been extensively studied compared to a static one due to a technical difficulty. In this study, the zero moment point method (ZMP) is used for analysing a stability of the elderly. We found that the dynamic instability of the elderly is associated with medial-lateral movement rather than anterior-posterior one.
