Trial Outcomes & Findings for Validation of Point Partial User Needs With Partial Finger Amputees (NCT NCT05012657)

NCT ID: NCT05012657

Last Updated: 2024-11-08

Results Overview

User wears Point Partial(s) for a full day (Pass/Fail). This validation method was used to confirm the following user need of the Point Partial has been met: Point Partial shall be comfortable for a full day's use. A simple pass/fail result was recorded for each user need for each participant. An overall passing rate above 80% across all user needs and participants is considered a success. Each participant attended a single-day experimental session. A day-use prosthetic socket was fabricated and Point Partials were mounted to the socket. Then, each participant attempted the validation test.
