| Outline of Final Research Achievements |
We investigated how individuals with unilateral transfemoral amputation (TFA) can perform step-over-step stair descent and ramp descent using a stance-yielding prosthetic knee that helps the prosthetic knee flex gradually during weight bearing. The results indicated that, during step-over-step stair descent, those with TFA put the posterior 1/3 of their prosthetic foot on the tread to descend the stairs faster than step-to-step one. We should keep in mind that the contralateral limb is subject to excessive loading in turn. For ramp descent, we observed that individuals with TFA could make the most of the functionality of stance-yielding knees by making a smaller step and walking slowly. These findings would be helpful for teaching these locomotive activities for those with TFA and evaluating the performance during rehabilitation process.
