Potential At-Home Therapy for Veterans with Limb Loss
By Katherine Bach and Brad Isaacson, PhD, MBA
Researchers from the Uniformed Services University (USU) and Walter Reed National Military Medical Center (WRNMMC) showcased the Rehabilitation Lower-Limb Orthopedic Analysis Device (ReLOAD) system, a device that amputees can use for at home therapy, at the first annual ACCelerate Creativity and Innovation Festival.
The event, which celebrates the nexus of science, engineering, arts, and design in an effort to showcase new interdisciplinary technologies developed to address global challenges, was held at the Smithsonian Institute National Museum of American History in Washington, DC, and sponsored by Virginia Tech’s Institute for Creativity, Arts, and Technology and the Smithsonian Museum’s Lemelson Center for the Study of Invention and Innovation.

The ReLOAD system employs a mobile array of wearable sensors that individuals with amputation, including wounded warriors and veterans can utilize for “at home” therapy. The system connects to an iPad and captures kinematic motion data during walking and then uses this data to provide real-time auditory feedback to the user in the form of music warping and voice commands in order to improve the user’s gait and walking patterns.

It is estimated that more than 2 million Americans currently live with limb loss, including numerous wounded warriors and veterans. According to Pasquina, “One of the most critical elements of recovery after lower limb amputation is the ability to successfully use a prosthesis (artificial limb) to promote independent mobility.”
Reduced mobility and improper gait mechanisms can lead to increased health problems such as cardiovascular disease, osteoarthritis, chronic pain, and reduced quality of life. Decreased access to consistent outpatient care complicates the rehabilitation of individuals with limb loss, especially those with reduced mobility. “The MDORP study [the parent study of the ReLOAD system],” he says, “aims to improve rehabilitation and health by providing state-of-the-science home therapy.”
