The objective of this study is to evaluate the efficacy of the Point Powered system as compared to the patient's standard-of-care treatment. This study will be a single subject crossover design where one group of 10 adult partial hand amputees will be evaluated on several metrics on their existing prosthetic treatment (Treatment 1) and the Point Powered system (Treatment 2) over a period of three months using standard two-site myoelectric control. Metrics include: in-clinic functional measures, subjective assessments, bilateral hand use, and prosthesis wear time.
