Fig. 1. Example of electromyography recordings of the MS and DA muscles with absolute value processing (A, B) and their power spectrum obtained using the FFT algorithm (C, D). The FFT algorithm converts a time-domain signal into its frequency components. The power spectra (C, D) selectively show the range of 0-10 Hz out of the entire range of 0-500 Hz to examine the low-frequency region. Red arrows indicate data points at 1 Hz corresponding to the chewing rhythm. MS, superficial masseter muscle; DA, anterior belly of the digastric muscle; FFT, fast Fourier transform.
