简要总结
The purpose of this research is to validate the e-MIP design and function by testing the ability of e-MIP to harvest energy and return a sufficient amount of energy to assist the user during gait. The investigators will also evaluate whether prosthetic users are able to wear and use the e-MIP device long-term.
