Prosthetic Hands & Arms that “Belong” Dustin Tyler and colleagues provide the first long-term evidence that the under-the-skin wires and nerve electrodes for a neuroprosthetic hand can last after being subjected to real-world use by two adult male amputees. Both men had surgeries in which three electrodes were implanted around their remaining nerves and connected to a prosthetic hand. Following surgery, the recipients were able to perform everyday tasks for over a year (including strenuous outdoor activities such as chopping wood) without problems, demonstrating the long-term durability of the prosthetic interface. In addition, the researchers also developed a way to improve sensory perception in the prosthetic hands. After stimulation, the patients reported feeling like they were grasping objects with their own hand, rather than feeling like they were using an external tool.
