VA Center of Excellence for Limb Loss Prevention and Prosthetic Engineering

Our research center provides broad based investigators the opportunity to conduct basic and clinical research and disseminate their findings in an effort to impact the quality of life and functional status of veteran amputees and veterans who are at risk for amputation. The two general areas of research are Limb Loss Prevention and Prosthetic Engineering.


Limb Loss Prevention

Veterans with peripheral vascular disease and/or diabetes have a greater risk of lower extremity amputation. Amputations usually result in functional decline, reduced independence, and increased health care costs. The most common cause of amputation is mechanical skin injury of the foot. Our research enhances our understanding of the relationship between foot structure and foot function and explores how diabetes mellitus alters the biomechanics of the foot.

Prosthetic Engineering

Our research identifies interventions and treatments that enable lower limb amputees to best achieve their vocational and recreational objectives. We employ a combination of theoretical, laboratory, and field studies to demonstrate the efficacy of current clinical practices, explore new-to-market interventions, and develop next generation devices intended to enhance the quality of life and functional status of lower limb amputees.
