Optimizing Gait Rehabilitation for Veterans With Non-Traumatic Lower Limb Amputation
VA Office of Research and Development
Summary
The population of older Veterans with non-traumatic lower limb amputation is growing. Following lower limb amputation, asymmetrical movements persist during walking and likely contribute to disabling sequelae including secondary pain conditions, poor gait efficiency, impaired physical function, and compromised skin integrity of the residual limb. This study seeks to address chronic gait asymmetry by evaluating the efficacy of two error-manipulation gait training programs to improve gait symmetry for Veterans with non-traumatic lower limb amputation. Additional this study will evaluate the potential of error-manipulation training programs to improve secondary measures of disability and residual limb skin health. Ultimately, this study aims to improve conventional prosthetic rehabilitation for Veterans with non-traumatic amputation through gait training programs based in motor learning principles, resulting in improved gait symmetry and lower incidence of long-term disability after non-traumatic lower limb amputation.
Description
The focus of this study is to improve walking symmetry in order to optimize walking ability and reduce disability for Veterans with non-traumatic lower limb amputation (LLA). Over 80% of current LLAs are non-traumatic, resulting from complications of pathologies, such as diabetes mellitus and peripheral artery disease. Despite current declines in total amputation rate among Veterans, the population with non-traumatic LLA is growing. For example, from 2000 to 2004 the relative amputation rate decreased by 34%. However, due to an increase in the number of Veterans with diabetes during the same p…
