In its longstanding role as a world leader in prosthetics research, VA's research program supports a broad portfolio related to amputations and prosthetics. In addition to continually developing improved materials and designs for prostheses, VA investigators are working to identify the best match for Veterans' prosthetic needs by collecting information such as how various prosthetic devices are used and how satisfied users are with each type.
Among those receiving prosthetics-related care in the VA system are many of the estimated 6 percent of wounded service members returning from Iraq who have lost a limb, and many other Veterans whose amputations were necessitated by diabetes, peripheral vascular disease, and other disorders. The total number of Veterans accessing VA health care for prosthetics, sensory aids, and related services has increased by more than 70 percent since 2000.
VA researchers constantly strive to improve the construction of prostheses, using leading edge technologies such as robotics, tissue engineering, and nanotechnology to create lighter limbs that closely mimic their natural counterparts. The integration of body, mind, and machine is a major guiding principle as VA specialists design and build artificial limbs that look, feel, and respond like natural arms and legs.
Important areas of VA research on amputation and artificial limbs include:
More than 40,000 Veterans, and a total of more than 250,000 Americans, have serious spinal cord injuries and disorders that may interfere with brain signals that control muscle movement. Many others have become blind from the loss of "photoreceptors" in the eye. For Veterans with these and some other types of functional loss due to disease or injury, VA investigators hope to restore function with electrical currents delivered through means of a "neural prosthesis." undergo amputation.
Important areas of VA research in neural prostheses include:
To ensure that no time is lost translating VA's groundbreaking research into life-improving advances in care, the VA Research and Development program relies on extensive collaboration among basic science researchers, clinician investigators, and rehabilitation specialists. VA has for the last several years conducted a series of "State of the Science—Research to Clinical Practice" workshops in cooperation with the Department of Defense and Walter Reed Army Medical Center on topics such as prosthetics, spinal cord injury, and wheelchair technology. Upcoming workshops are announced at www.herlpitt.org.
To stay up to date on the latest in prosthetics and rehabilitation care, read VA's international, peer-reviewed Journal of Rehabilitation Research and Development (JRRD). For more than 40 years, this leading research journal has published current information in the field of rehabilitation medicine and technology, including original studies, topic reviews, and commentaries related to amputation, prosthetics, and many other topics. For more information, go to www.rehab.research.va.gov.
VA has an integrated delivery system to apply the latest technologies in prosthetics and related devices for their intended benefit: to maximally restore a Veteran's quality of life.
In a single recent year, for example, VA specialists provided about 150 Veterans with a "C-Leg," a sophisticated computerized leg that allows people with amputations above the knee to walk in a more natural way.
At Walter Reed Army Medical Center, VA's vocational rehabilitation and employment program has provided voice-recognition computers so OEF/OIF Veterans who have lost a hand can effectively use computers without having full typing capability.
The goal of VA prosthetic care providers goes far beyond teaching a patient with an amputation to walk or use an artificial arm.
Support for independent living can even extend to home improvements and adaptive equipment for the cars of Veterans with amputations or other service-connected disabilities. Long-term care and support from VA care teams have been shown to help some patients continue to improve their functioning months or even years after their injuries.
