One of the prospective and newest treatment methods of modern electrostimulation is treatment using rhythmic (impulse, trapezoidal, exponential) currents. Indicators of such rhythmic currents should be determined in such a way that they correspond to the physiological rhythm of the biological system in action. For this purpose, the article looks at the design of the stimulation device on the NE555 digital timer in order to stimulate biologically active points. As a result of the stability of the microcircuit, hard pulses are obtained, so it is recommended to use it in the design of the impact device on biologically active points. By means of frequency modulation, two working frequencies were determined in the stimulation device: low frequency range (< 10 Hz), high frequency range (> 50 Hz).
