The goal of this project is to understand the factors that affect skin temperature (e.g., tissue above amputation site, and opposite foot) in people with amputation and diabetes. This project will also test the effects of 'shock-absorbing' prosthesis on skin temperature responses.
The overall goal of this project is to understand the factors that affect impaired temperature control in individuals with a leg amputation for areas vulnerable to damage, such as the tissue above the amputation site and the opposite intact foot. Abnormal tissue temperature is associated with risks for tissue damage, such as ulcers and pressure sores, especially in people with diabetes. In this study, we aim to study the effects of biomechanics and vascular physiology on tissue temperature responses. We will also determine the effectiveness of prosthetic shock-absorbing components in protectin…
Inclusion Criteria: * Individuals with a unilateral transtibial amputation, divided into two groups (with and without diabetes) * Participants must classify as Medicare class K2 or higher (who can traverse low-level environmental barriers such as curbs, stairs or uneven surfaces). * Participants must have undergone amputation at least 6 months prior. * They must have the ability to walk for at least 10 continuous minutes without undue fatigue. Exclusion Criteria: * Neurological impairment that may affect walking function, such as stroke, severe traumatic brain injury, Parkinson's disease, a…
the intervention will test the difference between rigid and shock-absorbing pylons, while the same prosthetic foot is applied in each condition.
