Innovative surgery for improving lower limb prosthetics and reducing pain in amputees

A Novel Approach to Lower Extremity Residual Limb Revision to Augment Volitional Motor Control, Restore Proprioception and Reverse Limb Atrophy

NA · Brigham and Women's Hospital · NCT04063592

This study is testing a new type of surgery for amputees to see if it can help reduce pain and improve movement by using special devices in their residual limb.

What this trial studies

This study focuses on a novel surgical revision technique for patients with lower extremity amputations, aiming to enhance motor control and sensory feedback through the incorporation of biological actuators in the residual limb. The research will evaluate the effectiveness of this approach in alleviating phantom limb pain, restoring proprioception, and regenerating muscle mass. Specific aims include developing a standardized surgical technique, assessing the functionality of the actuators, and creating a tailored rehabilitation strategy for post-operative care.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18-65 who have undergone above or below knee amputation and experience significant pain or discomfort from their residual limb.

Not a fit: Patients who are not in good health to undergo surgery, have impaired wound healing, or suffer from extensive peripheral neuropathies may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve the quality of life for amputees by reducing pain and enhancing the functionality of prosthetic limbs.

How similar studies have performed: While this approach is innovative, similar studies have shown promise in enhancing prosthetic control and reducing phantom pain, suggesting potential for success.
