Regulatory Clearance of the Glide Control Strategy for Upper Limb Prostheses

Study Summary

The investigators will test the following hypothesis: Use of Glide results in improved functional performance, satisfaction, and usage metrics as compared to use of a standard Direct Control (DC) prosthesis. This study will compare the use of Glide \[Experimental\] prosthesis with a DC \[Standard\] prosthesis in a clinical setting and in unsupervised daily activity. We will follow a multiple baseline design, specifically an AB design. Each of the subjects will use the Experimental and Standard systems over a total of 24-weeks. The A phase is the baseline phase where the DC prosthesis will be used, and the B phase will be the treatment phase where the Glide prosthesis will be used. Participants will undergo an A phase of either 10-weeks, 12-weeks, or 14-weeks duration, with the remaining 14-, 12-, or 10-weeks of the study being dedicated to the B phase.

Primary Outcome

CAPROQ is a validated patient reported outcome measure that captures key facets of rehabilitation for adults with UL absence or loss: perceived function, satisfaction, and pain. CAPROQ includes a total of 28 questions spread across three sub-scales: 8 satisfaction, 10 perceived functioning, and 10 pain subcategory questions. Responses to all questions are given on a 10-point, Likert-type scale. Higher scores therefore indicate higher levels of overall satisfaction. A singular total CAPROQ score
