Several studies have compared the tradition knee prescription protocol for young children with limb loss to an "Early Knee" protocol that prescribes a working knee in the first prosthesis. To date, comparison of knee function has been limited to a single number: peak flexion angle. This study compared children in the Early Knee protocol to age-matched controls using Dynamic Time Warping, which quantifies differences in the entire curve in aspects of both amplitude and temporal phasing.

Prosthesis users have difficulty ambulating on uneven terrain. This may be in part, due to limitations of prosthetic feet. Here qualitative results from on ongoing study will be presented to share user experiences with a prosthetic foot with polycentric ankle.

We explored the effect of systematically adjusting the knee flexion resistance of a transfemoral prosthesis on key features of the swing phase of gait. In this presentation we will present and discuss the results of five individuals walking with a prototype knee that permitted adjustment of swing phase flexion damping in isolation of other factors that could influence prosthesis behavior.

A common complaint amongst lower limb prosthetic users is excessive sweating at the residual limb. Silicone liners further increase residual limb temperature and trap the resultant sweat on the skin's surface, leading to possible complications. Perforated liners allow sweat to escape from the surface of the skin, keeping the residual limb dry and maintaining skin health. Improvements were observed in patient-reported outcome measures related to residual limb health and pain levels.
