Method of searching optimal zones for electropulse therapy (variants)

Abstract

The group of inventions relates to medicine (physiotherapy). Electric stimuli which are generated by the following ringing circuit: active electrode—inductive storage unit—passive electrode—interelectrode tissues—active electrode, contain oscillations which are used as a test signal. In one variant of the method the electrodes are successively applied (in another variant—moved uniformly) across the skin area. Every time the electrodes-to-skin contact is detected, the oscillation parameters are recorded after a delay. Moreover, the values of parameters can be averaged. The group of invention provides the use of both combined and disjointed (separated) electrodes. An optimal zone for electropulse therapy is identified by minimal or maximal value of one or more parameters of the aforementioned oscillations and the use of the principle of “small asymmetry”. The group of inventions provides an increase in the accuracy with which zones optimal for electropulse therapy are identified and localized.

AI Technical Summary

Benefits of technology

[0017]The aim to which the proposed invention is directed is to minimize the influence of such unavoidable subjective factors as non-uniformity of the speed of application and force of pressing of the electrodes on the skin on the results of measurement of parameters of free oscillations, which appear during the electropulse stimulation with stimuli generated by the inductive energy storage unit when searching for optimal zones for electropulse therapy by successive electrode applications.

[0018]As a result, the reliability of identification and accuracy of localization of optimal zones for electropulse therapy are increased when parameters of free oscillations are used for their searching.

[0019]The second aim to which the proposed invention is directed is to provide the possibility of searching optimal zones for the electropulse therapy during the labile method of stimulation, when the electrodes are moved uniformly across the entire surface of the chosen skin area.

[0020]The technical result of using the proposed method is the increasing of objectivity and accuracy in identifying the optimal zones for electropulse therapy by reducing the influence of subjective factors, and, also, providing the possibility of such search during labile stimulation.

Problems solved by technology

This method allows the evaluation of the body's reaction to the stimulation with the selected criteria, but does not provide for the search of zones optimal for electropulse therapy, which can be carried out using the same criteria by identifying the skin areas that are most different from those of the surrounding skin.

The drawback of this method is the considerable dependence of the parameters of free oscillations on the speed and force of the electrode pressing to the patient's skin, especially when the electrodes are being applied to the skin.

Their minor deviations may result in significant differences in the measured values of free oscillations parameters and, therefore, an incorrect identification of the body's reaction to the stimulation or the nature of pathology.

Another drawback of this method is the lack of averaging of measured values, which can also lead to a significant error in the evaluation of the body's reaction to the stimulation or the nature of pathology due to the high variability (dynamic properties) of the signal.

In addition, this method does not provide an evaluation of the body's reactions to the stimulation when the electrodes are moved along the skin.

Although this method does not support the searching of the optimal zones for electropulse therapy, it can also be used for these purposes by identifying the skin areas that are most different from the surrounding ones by the measurements of frequency, or amplitude, or damping of oscillations occurring in the aforementioned ringing circuit.

However, due to the lack of delay between the application of electrodes to the skin and the measurement of oscillations parameters, and also because there is no averaging of oscillation parameter values, this method cannot ensure the gage reproducibility in case of deviations in the speed of electrode application or the force of electrode pressing to the patient's skin.

Another drawback of this method is that it allows an evaluation of the electrophysiological state only in static condition, and does not allow it to be carried out when the electrodes are moved along the skin.
