Statement of the problem. The introduction of new magnetotherapy devices in clinical practice involves the use of previously tested physiotherapeutic techniques. Changes and modernization of the design of the field-forming system and control loops in the developed medical devices leads to a change in the presentation format and the engineering description of magnetotherapy techniques. Such facts require the use of correct approaches to presenting the methods of physiotherapeutic effects of newly created magnetotherapy systems. The selection and justification of the provisions that determine the process of adapting medical techniques for a new model of the magnetotherapy system is based on an analysis of the characteristics of the magnetotherapeutic agents inductors, as well as algorithms for reconfiguring the number and composition of the channels for forming the magnetic field for multichannel and multielement field-forming systems. The methods of magnetotherapy systems of the Multimag and RelaxMag series of the Kasimov Instrument Plant were used as objects of research.

Aim of the work – the development of sound approaches to the description of physiotherapeutic techniques, as well as the implementation of automated software for adapting already proven therapeutic methods for a new model of a magnetotherapy system. Results. Three approaches have been developed to describe physiotherapeutic techniques. The first approach characterizes the technique from the standpoint of functional purpose or a medical criterion for obtaining a positive therapeutic effect. The second approach is based on the description of the configuration of the generated magnetic field or the characteristics of the spatiotemporal distribution of its parameters in the field of influence. The third approach considers the technique as a set of data designed to control the hardware of physiotherapy systems. In this case, a specific hardware and software implementation of a magnetotherapy apparatus with a list of operating modes and a set of adjustable biotropic parameters of the therapeutic effect is considered. Software has been created to control the matrix of intelligent independent inductor cells, informative user interfaces, virtual channels from inductors, which in space form an analog of the so-called Multimag complex – a pseudo-solenoid. To automate the process of forming methods for the RelaxMag system, a software converter was developed. A feature of the program is the ability to scale the amplitude and time parameters of adaptable techniques.

Practical significance. The adaptation of proven therapeutic techniques will allow new magnetotherapeutic agents to use the medical database accumulated over decades, reproduce techniques with an expanded set of biotropic parameters and create new techniques, effectively adjusting them for a particular patient.
