質量負荷・歩調の異なる階段降段歩行の慣性協調に関する慣性運動度・体幹前屈角の解析

抄録

We investigated the inertial coordination in stair descending with different inertial forces, supposing the situation that a person wears a wearable machine. We observed five healthy adult males walking with varying mass load and cadence, and analyzed their gait and closeness to inertial movement based on a kinetic energy metric. The results illustrated that the inertia harmonization appeared in common before the heel contact of swing leg and the time duration was at most 20 % time of a step in the all subjects and the all mass-load & cadence conditions. Moreover, the trunk anteflexion of 5 deg contributed to the improvement of the inertia harmonization in mid-swing phase and terminal- double-stance phase.
