Wireless Non-Invasive Advanced Control of Microprocessor Prostheses and Orthoses II

In Brief

A clinical study evaluating ASTERISK System and Wired Configuration for Prostheses and Upper Limb Amputation Below Elbow. Completed, enrolled 4 participants across 1 site.

Detailed 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.

Interventions

ASTERISK Systemdevice

This intervention uses an experimental socket fabricated by a certified prosthetist. The electronics within the experimental socket are set up with the ASTERISK system, which sends information collected from the EMG sensors to the prosthetic hand wirelessly rather than the current available method of wired control.

Wired Configurationdevice

This intervention uses the same experimental socket that is used for the ASTERISK intervention. The prosthesis is set-up with wired EMG control, which is the current available method for EMG-controlled prostheses.
