Adjusting to life after an amputation often includes adjusting your eating habits. If your goals include improving your health, healing, and returning to your active lifestyle, then nutrition plays an important role in getting you there. Check out HPRC’s Performance Strategies for “Healthy eating for amputees,” which has tips on how to eat healthy and balanced after an amputation.
In 2013, the Research Institute of Chicago (RIC) presented the first mind-controlled bionic leg, thanks to support from the U.S. Army Medical Research and Material Command's (USAMRMC) Telemedicine and Advanced Technology Research Center (TATRC). Until now, this technology was only available for prosthetic arms. These brainy bionic legs are still being studied and perfected, but it’s hoped that they will be available in the next few years. This life-changing technology will be able to help the more than 1,600 service members who have returned from Iraq and Afghanistan with amputations. Bionic limbs will make the transition to active duty or civilian life smoother for wounded warriors.
In one case study, a civilian who lost his lower leg in a motorcycle accident underwent a procedure called “Targeted Muscle Re-innervation”. This procedure redirects nerves that originally went to muscles in the amputated limb to still-healthy muscles in the limb above the amputation. As these healthy muscles contract, they generate signals that are detected by sensors within the prosthetic and analyzed by a specially-designed computer chip and program The program rapidly decodes the type of movement the individual is preparing to do, such as bending the knee, and then sends those commands to the leg. This allows the person to walk up and down ramps and stairs and transition between activities without stopping. The user also can move (reposition) the bionic leg just by thinking about it, which is not possible with current motorized prosthetics.
The bionic leg is also showing a decreased rate of falling and quicker response time. Stay tuned for availability of this groundbreaking technology.
