Abstract Details

2022, Master of Sciences, Case Western Reserve University, Biomedical Engineering.
The composite flat interface nerve electrode (C-FINE) can be used to functionally activate paralyzed muscles. We evaluated the recruitment properties of 16 contact C-FINEs implanted around the nerves of the right upper extremity of a tetraplegic human participant using pulse width (PW) modulated recruitment curves. Muscle activation was quantified using the electromyographic (EMG) response to twitch activation. Selectivity was defined as the maximum percent activation of a muscle before any other muscle reached a 20% activation threshold. We found that it was possible to selectively activate 24/25 muscles, but that selectivity values ranged widely. We were able to successfully create functional stimulation patterns from the acquired recruitment information. We found cuff-wide trends in activation thresholds that indicate the location of each nerve in its cuff. Due to the differences in activation threshold across each cuff, future characterization work should intelligently vary both PA and PW in order to increase efficiency.
