Regenerative Peripheral Nerve Interfaces for Advanced Control of Upper Extremity Prosthetic Devices.

The quest to find the ideal prosthetic device interface that enables intuitive control has motivated several recent innovations. Although current prosthetic device control strategies have advanced the field of neuroprosthetic control, they are limited in their ability to generate reliable, stable, and specific signals to replicate the complex movements of the upper extremity. The regenerative peripheral nerve interface (RPNI) is a promising solution to enhance prosthetic device control. This article describes the development of RPNIs and summarizes its successful use in the control of advanced prosthetic devices in patients with upper extremity amputations.
