Summary
The goal of this proposed project is to evaluate the effectiveness of our novel wireless electrode system, which the investigators refer to as the Asterisk system, on transradial prosthesis users. There are numerous benefits to the upper limb prosthesis community being able to utilize wireless electrodes. These benefits include allowing for the use of a prosthetics liner to assist with fit and comfort, easier implementation of electromyography (EMG) controlled (also referred to as myoelectric control) prosthesis for individuals with osseointegration, and additional EMG electrode location options if the muscle activity captured within the prosthetic socket does not provide reliable prosthesis control. The investigators intend to use this data to develop the Asterisk wireless electrode system into a commercial product. The findings will also be shared with the research community to help drive the design of future devices.
