Intramuscular EMG channel performance. Examples of raw EMG and computed WFL recorded while participants move to 18 postures, with and without 70 Hz single contact stimulation via the proximal median (pM) nerve C-FINEs. a Example EMG channel that displayed low noise and clear amplitude modulations during rest and movement phases, regardless of stimulation. b Example EMG channel that showed increased EMG signal power with stimulation throughout all moments in time and at all frequencies. c Example EMG channel that showed increased noise at the stimulation frequency and harmonics through the trial. d Categorization of intramuscular EMG recording performance for each participant
