歩行パラメータと歩行安定性指標間の関係性に対する統計的年代間比較

抄録

Margin of stability (MoS), which is a dynamic gait stability index, are computed in the anterior and mediolateral directions. However, how the relationships between the mediolateral and anterior MoSs vary depending on ages has not been well investigated. The inter-age comparison reveals age-specific walking characteristics and their effects on stability. We used the multiple indicators, multiple causes model in order to investigate the effects of gait parameters on the MoSs, then discussed their differences between healthy participants over 60 years old and those in their 20s. The MoSs in two different directions were mostly independent for the young adults; however, they interfered with each other for the elderly.
