Development of a non-actuated wearable device to prevent knee buckling

Wearable devices are required not only for assisting the gait motion of the elderly but also for improving the gait stability. Thus, a non-actuated wearable device was developed in this study. The device intended to prevent knee buckling by supporting knee using string placed along with body surface. In order to arrange the force pattern, a string length adjustment mechanism was developed. The experimental result suggested that this wearable device could successfully generate knee extension torque which mitigated knee buckling.
