Orthotics and Prosthetics User Survey - Satisfaction With Device (OPUS-SD)Primary· At the end of each 1 month condition
The Orthotics and Prosthetics User's Survey (OPUS) is a self-report questionnaire consisting of five modules. The version of the OPUS which will be administered consists of 9 questions in 1 category (satisfaction with device). Questions are asked and scored on a scale from 0-4 (0=strongly disagree, 1=disagree, 2=neither agree nor disagree, 3=agree, and 4=strongly agree), with a higher value indicating a better outcome. There is an additional response for "Don't know / Not Applicable", which if chosen, is not included in the scoring.
This survey will be given at the end of each study condition

Sponsor's own description
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.
