[The choice of the time for the application of a magnetic field based on hemodynamic parameters].

The objective of the present study was to develop a criterion for the choice of the time for the application of an alternating magnetic field (MF) based on the results of the treatment of 25 healthy female volunteers aged between 22 and 26 years on day 7 of the menstrual cycle. The 0-50 Hz magnetic field with magnetic induction (2-10 mT) and modulation depth in the range from 0-100% was applied to the abdominal region for 20 minutes. Characteristics of the magnetic field were chosen on an individual basis taking into consideration the age, sex, height, body weight, basal metabolism, and the type of blood circulation. The efficacy of influence of the magnetic field was estimated from rheographic characteristics. It is concluded that the duration of magnetic field application should be restricted to the time during which the maximum of the differential rheogram increases by not more than 10% of its initial value.

[Characteristics of hemodynamic and skin temperature during application of individually prescribed and corrected magnetotherapeutic regimes (experimental study)].

The objective of this study was to determine functional characteristics of the cardiovascular system and skin temperature believed to adequately reflect its response to the action of an alternating magnetic field (AMF). The estimated parameters included index of cardiovascular regulation and average temperature of the body surface. The time and the skin temperature were determined for each value of regulation index at which AMF action should be terminated. Algorithm for the choice of the AMF treatment regime and its correction depending on body surface temperature and its correlation with the index of cardiovascular regulation.
