Sam, an 11-year-old violin player was born without fingers or a thumb on his right hand. In order to learn the basics of violin, he currently uses a custom made prosthetic that allows him to hold a violin bow. However, his current prosthetic does not allow for the bow angle to change relative to his wrist, and thus, he cannot perform many techniques that are important to him furthering his violin skills. Specifically, his prosthetic allows Sam to use only a small percentage of the bow. For this project, a prosthetic was designed for Sam with the goal being to allow Sam to replicate full wrist motion such that he can keep the bow perpendicular to the violin strings and use an increased percentage of the length of the bow. The prosthetic needs to be light and comfortable so that Sam can play for extended periods of time.
