简要总结
The purpose of this study is to perform a biomechanical study of a prototype prosthetic foot and evaluate if it provides a physiological generation of power at the ankle in transtibial amputees. The prosthetic foot is a prototype system that generates power via actuators (i.e. robotic system).
详细描述
Subjects will be studied during level-ground walking. A camera-based motion capture system will be used to study the biomechanics of motion and evaluate if the pattern of ankle power generation by the prosthetic foot is physiological. In addition, the metabolic cost of ambulation will be monitored during walking at constant speed over a period of several minutes. The data will allow us to assess if the prosthetic foot leads to a decreased metabolic cost of ambulation compared to passive prosthetic feet.
