Walking Exercise Sustainability Through Telehealth for Veterans With Lower-limb Amputation

Despite recent advances in physical rehabilitation, Veterans with lower-limb amputation have poor long-term outcomes, including severely limited functional capacity and high levels of disability. Such poor outcomes are compounded by a lack of exercise participation over time, even with use of lower-limb prostheses. There is a clear need to advance current rehabilitation strategies to better promote sustained exercise following lower-limb amputation. To address this need, the study will determine the potential of a walking exercise self-management program to achieve sustained exercise participation. The 18-month intervention is focused on helping Veterans reduce habitual sedentary behavior through a remote exercise behavior-change intervention that includes multiple clinical disciplines, individualized exercise self-management training, and peer support. This innovative approach shifts the conventional rehabilitation paradigm to specifically target life-long exercise sustainability and remove an underlying cause of disability for Veterans with lower-limb amputation.

Evaluation of a New Articulated Prosthetic Foot: Comfort, Safety and Biomechanics in Individuals With a Lower-Limb Amputation

This clinical investigation aims to evaluate a new articulated prosthetic foot during daily-life activities.

Motorized Prostheses for Lower-limb Amputees

The investigators will assess biomechanical and functional mobility outcomes in individuals with unilateral, above-knee amputations using different knee/ankle configurations of a lightweight powered prosthesis and different volitional controllers in individuals with unilateral, above-knee amputations.
