The purpose of this study is to evaluate the effects of myo-electric training tools on prosthesis functional outcomes.

Participants will undergo informed consent and schedule an initial site visit. A logging device will be used to track activity of prosthetic arm usage while in everyday use at home. After a baseline period, participants will schedule a second visit to be introduced to the training technology.

The study will span up to 7 months with participants training at home for 15-60 minutes, 3-5 times a day. Every 3-6 weeks, investigators will schedule a study event and sit visit to conduct functional outcome tasks and measurements.
