Background and Purpose: The number of people living with an amputation in the United States is rising at a rate of almost 200,000 cases a year [1]. The incidence of low back pain (LBP) in individuals with lower limb amputation (LLA) has been shown to be much greater than in the general population at 52%- 72% [2-4]. High amputation level, disuse, and abnormal movement patterns associated with prosthetic gait have been theorized to lead to decreased lower back muscle performance, contributing to the high prevalence of LBP in individuals with LLA [5-7]. However, lumbar muscle morphology and performance have not …

Purpose/Hypothesis: A patellar-tendon-bearing (PTB) bar is a common prosthetic design feature used in individuals with trans-tibial amputations. As the patellar tendon in the knee of residual limb is subjected to the perpendicular compressive force not commonly seen in normal tendon loading, it is possible for tendon remodeling and degeneration to occur over time; however, there is limited data to support this idea. The primary purpose of this study was to use ultrasound imaging to compare the morphological differences between tendons of the residual and intact limb in unilateral trans-tibial amputees who utilize a prosthesis with a PTB feature. We hypothesized …
