Comparison of Pattern Recognition Control and Direct Control in TMR

Completed · Not applicable

Conditions studied: Amputation, Amputation; Traumatic, Arm, Upper

In brief

Targeted Muscle Reinnervation increases the control signals available for commercial arm systems. A new type of control, pattern recognition, has been developed into a form that allows use with commercially available arm system. The goal of this project is a home trial, in which people who have had TMR will try the new controls and the new arm to find out if they are better than what is currently available. Home trials will also allow us to see what needs to be done to make our inventions work even better.

Who can join

Age: 18 and older, up to 95. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• A upper limb amputation at the transhumeral or shoulder-disarticulation level
• Successful TMR surgery
• Previous success at operating a myoelectric prosthesis using surface EMG signals from reinnervated muscles (not necessarily current prosthesis usage, although current prosthesis users may be more likely to use their trial prostheses).

You may not qualify if…

• Significant new injury that would prevent use of a prosthesis: The ability to consistently wear a prosthesis and perform activities of daily living and specific performance tasks is necessary to evaluate the relative benefits of the interventions.
• Cognitive impairment sufficient to adversely affect understanding of or compliance with study requirements, ability to communicate experiences, or ability to give informed consent: The ability to understand and comply with requirements of the study is essential in order for the study to generate useable, reliable data. The ability to obtain relevant user feedback through questionnaires and informal discussion adds significant value to this study. Of note, all TMR patients to date have normal cognitive function and we are not aware of any new brain injuries that would preclude participation
• Significant other co morbidity: Any other medical issues or injuries that would preclude completion of the study, use of the prostheses, or that would otherwise prevent acquisition of useable data by researchers.
