Evaluation of function, performance, and preference as transfemoral amputees transition from mechanical to microprocessor control of the prosthetic knee. Objective To evaluate differences in function, performance, and preference between mechanical and microprocessor prosthetic knee control technologies. Design A-B-A-B reversal design. Setting Home, community, and laboratory environments. Participants Twenty-one unilateral, transfemoral amputees. Intervention Mechanical control prosthetic knee versus microprocessor control prosthetic knee (Otto Bock C-Leg). Main Outcome Measures Stair rating, hill rating and time, obstacle course time, divided attention task accuracy and time, Amputee Mobility Predictor score, step activity, Prosthesis Evaluation Questionnaire score, Medical Outcomes Study 36-Item Short-Form Health Survey score, self-reported frequency of stumbles and falls, and self-reported concentration required for ambulation. Results Stair descent score, hill descent time, and hill sound-side step length showed significant ( P P P Conclusions The study population showed improved performance when negotiating stairs and hills, reduced frequency of stumbling and falling, and a preference for the microprocessor control C-Leg as compared with the mechanical control prosthetic knee. |
