简要总结
A pilot study comparing the emPOWER Ankle System to standard carbon fiber prosthetic feet, in active seniors.
详细描述
The primary objective of this study is to characterize the increase in the distance subjects can walk during a six (6) minute period while wearing the emPOWER Ankle compared to a passive lower-extremity prosthesis.

结局指标
主要结局
Number of Participants With Improvement, No Change, or Worsening in Performance in the Six Minute Walk Test (6MWT)
时间窗: 3 months with the emPOWER ankle
