ANALYSIS OF TRANSIENT PHASE OF BALANCE RECOVERY RESPONSE IN HUMAN LOCOMOTION

Takahiro Kagawa, Yoji Uno

Abstract

In this study, we analyzed the transient phase of reactive responses for balance recovery while walking. A cyclic EMG pattern during steady-state walking is regarded as a closed orbit in the state space of EMG signals. Since a disturbance induces a different pattern of EMG from the orbital EMG pattern, the distance between the orbit and the reactive EMG after disturbance is quantified by nearest neighbor distance. In addition, we evaluated the time series of the phase of the minimum distance which would reflect the modulation of locomotor rhythm for balance control.
