The Influence of the Course of Electrostimulation by the Device "VEB-1" on Metabolic Parameters of Practically Healthy Men

Abstract

Introduction. While constructing and creating the generator design for electrotherapy and stimulation of human nerve centers, we based on the following provisions. The influence of impulses of a rectangular shape (range 7-18 Hz) made it possible fix the frequency ranges of each basic nerve node. Low frequency had minimal effects of stimulation on the corresponding nerve node, while high frequency the maximum effect. For the effective excitation of nerve centers, the frequency beat method is used which consists in obtaining oscillations with close frequencies. To obtain the effect of the frequency, beats are generated by impulses of a rectangular shape to two signal channels. The channels differ in frequency which is known to be the beat frequency. For example, for obtaining a beat frequency of 6 Hz, impulses in the first channel were formed at a frequency of 30 Hz, in the second channel at a frequency of 36 Hz. When the first impulse is formed on both channels with a phase shift of 0o, we obtain an absolute zero current in the output. Figure 1 shows a periodic signal generated by frequency beats voltage in two channels to form a common output signal (a). Figure 1 is a graph of the current of the output signal (b). Such effect creates a shock wave through the object at the desired frequency. It also spins an electromagnetic field in the object. The generator has been assembled on the basis of the patent of Ukraine for the utility model 105875 "Portable device for electrotherapy and stimulation" [4]. Its operation is described in [6]. The generator has been assembled on the basis of a two-channel circuit using two frequency synthesizers, amplifiers, each of them generates its own frequency. Figure 2 shows a block diagram of the device indicating the movement of the electric current.
