This case study evaluates a novel kneeless prosthesis with powered length actuation (lengthening for push-off and shortening for toe clearance), which was hypothesized to result in greater stability, easier toe clearance, and assisted-forward progression, toward improving compensatory mechanisms of prosthesis users. Two persons with unilateral transfemoral amputation walked with both their habitual devices and the length-actuated prosthesis. Quantitative metrics of knee stability (thigh velocity and hip flexion/extension moment), mobility (ankle power, pelvis obliquity, hip abduction, toe clearance) and qualitative rankings were collected for both devices. Stability-related results showed increased confidence in the length-actuated prosthesis' knee buckling avoidance with decreased prosthetic-side early stance hip extension and swing hip flexion angle/velocity. Mobility-related metrics showed decreased confidence in the length-actuated prosthesis' toe clearance with increased frontal plane compensations and push-off ankle power (vaulting). Although both participants were encouraging of the overall concept, the user with higher mobility and a microprocessor knee preferred his own device, whereas the user with lower mobility and a passive knee preferred the length-actuated prosthesis. Both users had increased confidence (and decreased compensations) in knee stability during stance but continued to have compensations during swing to ease toe clearance.
