A new simulation model was created with a transfemoral prosthesis including a
residual limb muscle model during the swing phase. The optimal knee joint
friction value was calculated to minimize muscle metabolic energy expenditure.
Using this model to examine how an amputee could walk as fast as possible, the
minimum swing duration was calculated. The obtained optimal joint friction value
was close to the value the subject preferred when walking normally. The
calculated minimum swing duration was close to the time the subject could
achieve. The method of dynamic optimization with a musculoskeletal model used in
this study indicated the possibility of obtaining optimal mechanical properties
suited to each amputee's capability of mastering control of his/her residual
limb.
