Abstract: An electrophysiological signal measurement system, an electrophysiological signal adjustment method and an electrode assembly are provided. The electrophysiological signal measurement system includes an electrode assembly, a variation adjustment device and a signal processing device. The electrode assembly receives an electrophysiological signal, a first electrical characteristic value and a second electrical characteristic value. The variation adjustment device includes a comparison unit and a searching unit. The comparison unit receives the first electrical characteristic value and the second electrical characteristic value, and determines whether a difference between the first electrical characteristic value and the second electrical characteristic value is greater than a threshold. When the difference between the first electrical characteristic value and the second electrical characteristic value is greater than the threshold value, the searching unit searches for several amplitude calibration ratios corresponding to several frequencies. The signal processing device calibrates the electrophysiological signal according to the amplitude calibration ratios.
