The aim of this work was to test the Echelon foot efficiency to offer enhanced safety, comfort and function over a wide range of walking surfaces, inclines and stairs, thereby improving the quality of life for amputees.

Ten individuals with a unilateral trans- tibial amputation will participate in two test sessions- one while using their own prosthetic foot, the other while using the Echelon foot.

Further study details as provided by Dr. Itzhak Siev-Ner, Sheba Medical Center:

Primary Outcome Measures:
  • While using the Echelon foot the amputees will present lower internal mechanical strain in the soft tissue of the stump while standing on a 10 degrees platform. [ Time Frame: Beginning of the trial and one month after ]

Secondary Outcome Measures:
  • Using the Echelon foot the Kinematic of level ground walking and climbing up and down stairs will be closer to normal curves. [ Time Frame: At the beginning of the trial and one month later ]

Enrollment: 10
