Slideshow Project DOI: /JRRD JSP Aim – Compare biomechanics of ramp and stair descent and ascent for participants using C-Leg and Power Knee (PK). Relevance – Adding active power to prosthetic knee unit may improve function and reduce overuse injuries in persons with transfemoral amputation (TFA). – Servicemembers with TFA are often young and motivated to perform at high functional levels.

Slideshow Project DOI: /JRRD JSP Methods We collected temporal-spatial and kinetic data as subjects equipped with retroreflective markers ascended and descended instrumented staircase and 12 ramp at their comfortable pace.

Assessment of transfemoral amputees using C-Leg and Power Knee for ascending and descending inclines and steps. J Rehabil Res Dev. 2012;49(6):831–42. Slideshow Project DOI: /JRRD JSP Results Knee power generated by nondisabled limb during stair ascent was significantly greater for C-Leg than PK. Knee power generated by prosthetic knee unit was significantly greater with PK. Although PK reduced power required from nondisabled knee during stair climbing, it did not appear superior to C-Leg for other tasks.

Slideshow Project DOI: /JRRD JSP Conclusions Adding power to prosthetic knee may reduce wear on nondisabled limb. However, certain limitations still require improvement.
