Use of Low-frequency Magnetic Fields in the Hybrid Treatment of COVID-19 Patients

Study aim: The purpose of this study was to evaluate the efficacy of low-frequency magnetic field in the hybrid treatment of COVID-19 patients, i.e., including magnetostimulation in the standard treatment. Material and methods: The study was conducted on patients aged 39 to 80 years, of both sexes affected by COVID-19. The study subjects were recruited at the Covid Unit of the Military Medical Academy University Teaching Hospital - Central Veterans' Hospital in Lodz. The study group (13 patients) included patients hospitalized due to PCR (polymerase chain reaction)-confirmed SARS (severe acute respiratory syndrome) -Cov-2 infection, who were treated with magnetostimulation in addition to a standard therapy. The control group (10 patients) included patients receiving a comprehensive treatment without magnetostimulation. The patients hospitalized due to PCR-confirmed SARS - Cov - 2 infection were qualified for the study. Patients with absolute contraindications to magnetic field application and patients with limited verbal - logical contact were excluded from the study. In the study groups, the patients were subjected to magnetic field - magnetostimulation with the use of apparatus Viofor JPS System (mata). 14 treatments were performed, 7 times a week. Treatment parameters: 12 minutes M2P2 program, with increasing intensity from 1 to 8. The authors applied magnetic field with a frequency of 180 - 190 Hz, pulse packet frequencies between 12.5 and 29 Hz, packet groups 2.8 - 7.6 Hz, series 0.08 - 0.3 Hz, with magnetic induction B= 3.2 µT (on average) and B = 40 µT at a pulse peak. In laboratory tests, the following levels were assessed in the patients: interleukin 6 (IL -6), leukocytes (WBC), monocytes (MONO), platelets (PLT), CRP and d-dimers. The patients' blood was taken twice: on admission to the department and after a series of treatments with magnetostimulation. Approximately 6 ml of blood was collected at one time (3 tubes). Medical records of the patients and scientific reports collected from the University Library and medical databases, e.g. PubMed, were analyzed and discussed.
