Comparison of the quality of EMG signal from the tibialis anterior muscle group captured using biostamp and conventional equipment (needle electrodes and standard recording electronics) during stimulation of the common peroneal nerve. a Average current thresholds determined using biostamp and conventional equipment in response to stimulation of the peroneal nerve (n = 10 patients). b Bland–Alman analysis of biostamp and conventional equipment (needle, n = 55 subjects) showing data sets falling within +0.18 mA (upper limit: UL) and −0.15 mA (lower limit: LL). c, d EMG signals captured using biostamp and conventional equipment, respectively, for different stimulation currents with patient 1. e Signal-to-noise ratio (SNR) of EMG signals shown in c and d. f–h show similar data for patient 2. For parts c, d, f, and g, EMG amplitudes (y-axis) correspond to normalized values
