Medial knee loading responses to prosthetic foot stiffness during various ambulatory activities.

Individuals with unilateral transtibial amputation are often at elevated risk of knee osteoarthritis in the intact limb, which has been associated with increased medial compartment loading. Prosthetic foot stiffness has been shown to influence this mechanical loading, yet it remains unclear whether such effects persist...

A Synthetic Digital Anatomy Approach to Determine the Effects of Tissue Composition and Alignment on Transfemoral Residual Limb Mechanics

The soft tissue envelope within the residual limb influences prosthetic fit, function, and user comfort. The purpose of this study was to examine the influence of residual limb tissue composition and skeletal alignment on its mechanical properties during axial loading. We hypothesized that deviations in the adipose and...

Mobile Machine Learning Predictions of Bilateral Ground Reaction Forces During Variable Speed Walking and Prosthesis Use

Emerging methods, particularly in machine learning, are working to make completely untethered, mobile biomechanical analysis a feasible reality. Traditional instrumented gait labs remain as the gold standard, though moving beyond the physical constraints of these spaces provides several benefits. The two primary use ca...
