Biomechanical Evaluation of a Novel, Compliant Low Profile Prosthetic Foot

Biomechanical Evaluation of a Novel, Compliant Low Profile Prosthetic Foot

The investigators have developed a novel layered low-profile prosthetic foot that is able to provide enhanced compliance without sacrificing strength for individuals with transtibial amputation who have long residual limbs. It is hypothesized that the proposed prosthesis will offer similar benefits to these individuals as comparable higher profile prostheses offer users with shorter residual limbs. The primary goal of this Phase I proposal is to assess the degree to which the proposed prosthesis can provide benefits to prosthesis users in this population, along with characterizing the degree to which the novel prosthesis emulates its taller counterparts.

Inclusion Criteria:

1. 18-89 years old
2. unilateral transtibial amputation
3. daily use of a low profile foot
4. cognitive ability to understand and willingness to provide informed consent and follow the study protocol

Exclusion Criteria:

1. unable to perform walking for 2 minutes without an assistive device
2. other health conditions which may prevent them from participating in the study
