T字杖歩行中における両足と杖にかかる荷重に基づく動的安定性(MoS)の評価

抄録

In this paper, the change of dynamic stability (MoS) by two different calculation methods of BoS is compared and investigated. As a result, it was confirmed that the MoS tended to increase with the increase of the cane tip position when the end point of the BoS was the cane tip position where the cane touched the ground, which is the conventional method. On the other hand, when the end point of the BoS was the point where the moments of the three loads applied to the cane, the left foot and the right foot were balanced, the MoS tended to become smaller as the cane tip position was increased.As a result, it was confirmed that the MoS tends to decrease as the cane tip position is increased. This conclusion is consistent with the feeling of actually using the cane, so the proposed method is considered to be appropriate.
