Pattern Recognition Prosthetic Control
Completed · Not applicable
Conditions studied: Prosthesis User, Congenital Amputation of Upper Limb, Amputation; Traumatic, Limb
In brief
This study investigates whether simultaneous electromyographic (EMG)-based pattern recognition control of an upper limb prostheses increases wear time among users. In contrast to conventional, seamless sequential pattern recognition style of control which only allows a single prosthetic hand or arm function at a time, simultaneous control allows for more than one at the same time. Participants will wear their prosthesis as they would normally at home using each control style for an 8-week period with an intermittent 1-week washout period (17 weeks total). Prosthetic usage will be monitored; including, how often participants wear their device and how many times they move each degree of freedom independently or simultaneously. The primary hypothesis is that prosthetic users will prefer simultaneous control over conventional control which will result in wearing their device more often. The secondary hypothesis is that simultaneous control will result in more efficient prosthesis control which will make it easier for participants to perform activities of daily living. The results of this study will help identify important factors related to prosthetic users' preferences while freely wearing their device within their own daily-life environment.
