Can Sensory Feedback Training Improve the Biomechanical and Metabolic Effects of Using Passive or Powered Lower Limb Prostheses During Walking for Veterans With Transtibial Amputations?

VA Office of Research and Development·observational·Posted Jun 5, 2019·Updated Jul 15, 2025

In Brief

An observational study evaluating Passive-elastic prosthetic foot and Powered ankle-foot prosthesis for Amputation. Completed, enrolled 12 participants across 1 site.

Detailed Summary

Previous studies suggest that Veterans with below the knee amputation using passive-elastic or powered prostheses have impaired physical function, which could increase the risk of osteoarthritis, leg/back pain, and diabetes/obesity. Utilization of rehabilitation strategies/techniques such as real-time visual feedback training could restore physical function, increase physical activity, and reduce injury risk. The investigators will systematically determine the effects of using real-time visual feedback training of peak propulsive (push-off) force during walking while Veterans with below the knee amputations use a passive-elastic and battery-powered prosthesis. Similar to previous studies of non-amputee older (\>65 years) and post-stroke adults, use of real-time visual feedback training of propulsive force will likely improve walking function in Veterans with amputations. Such training presents a promising rehabilitation strategy that could reduce comorbidities, while improving quality of life, comfort, and physical function, and advancing rehabilitation research and prosthetic development.

Interventions

Passive-elastic prosthetic footdevice

The investigators will measure the biomechanics (motion, forces, and muscle activity) and metabolic rates while subjects walk using their own passive-elastic prosthesis with and without visual feedback of peak propulsive force targets.

Powered ankle-foot prosthesisdevice

The investigators will measure the biomechanics (motion, forces, and muscle activity) and metabolic rates while subjects walk using a battery-powered ankle-foot prosthesis with and without visual feedback of peak propulsive force targets.
