简要总结
The purpose of this descriptive and exploratory pilot study is to investigate: (1) sagittal plane hip kinematics and kinetics and (2) metabolic consumption/cost, for bilateral transfemoral walking with passive prostheses versus powered prostheses. The pilot study will collect data from three subjects with bilateral transfemoral amputations. Differences in kinetics, kinematics, and oxygen consumption/cost when comparing passive and powered components may indicate benefits for clinical application of powered devices for persons with lower limb amputation.
