Abstract

Background. Bioelectrical impulses, also known as brain wave rhythms, have been known for years to correspond with mental activities. Thus an electroencephalogram can produce concrete information regarding both the physiological status (alertness, sleepiness) and emotional status (tension, relaxation) of the subject, since these states are associated with particular bioelectrical patterns. The purpose of our study was to examine the effects on low-frequency magnetic fields on the amplitudes of bioelectrical activity in the cerebral hemispheres, as registered by EEG. Material and methods. EEGs were performed on 92 women, 21-23 years of age, in the Clinical Psychology and Psychophysiology Laboratory at the Maria Grzegorzewska Academy of Special Education in Warsaw. The subjects received low-frequency magnetic field stimulation or a placebo while performing cognitive tasks. All the subjects were examined 6 times to determine the behavior of alpha, beta, SMR, theta, and delta waves after magnetic stimulation. The results were recorded on-line from the F3 -C3 (left hemisphere) and F4-C4 (right hemisphere) leads. Results. Statistical analysis shows that low-frequency magnetic fields, regardless of hemisphere, have a positive effect on the amplitudes of the tested brain waves. Conclusions. In comparison to the right hemisphere, the low-frequency magnetic fields generated by the Viofor JPS device much more markedly improve the functionality of the left hemisphere, known as the „logical” hemisphere.

Romualda Mucha, Aleksander Sieroń – Follow-up of inflammatory and erosive lesions of glans penis during magnetic and LED light therapy – a case study. Fizjoterapia Polska 2010; 10(2); 165-169

Abstract
Introduction. The aim of the study was to assess the therapeutic effects of low induction magnetic field, R red light and infrared LED light on inflammatory and erosive lesions of skin and glans penis. The subject was a 50-year-old patient with a five-year history of balanoposthitis.Material and methods. The authors followed up and assessed inflammatory and erosive lesions of the skin of the penis and glans penis in a patient with recurring balanoposthitis. The patient underwent two 3-week sessions of treatment by active emission of a low induction magnetic field, red light and infrared LED light, called magnetic field and LED light therapy. The sessions were separated by a one-week break.Results. The evolution of inflammatory and erosive lesions of the penis and glans penis in response to magnetic field and LED light therapy indicates an anti-inflammatory effect of low induction magnetic field and LED light. Satisfactory results were obtained in the form of shallowing or complete closure of the erosions as well as regression of pain and itch.Conclusions. Treatment with low induction magnetic field, red light and infrared LED light, called magnetic field and LED light therapy, may be applied in the treatment of inflammatory and erosive lesions of the penis and glans penis.

Katarzyna Juścińska, Wojciech Garczyński, Ignacy Kłonowski, Tomasz Kowalik, Magdalena Gębska – Changes in mobility of the lumbar spine under the influence of a series of low-frequency magnetotherapy procedures – randomized single-blind study. Fizjoterapia Polska 2018; 18(3); 64-77

 

Abstract
Introduction. In the literature, we find many works emphasizing the great role of physical therapy in treatment of spinal disorders. Low-frequency magnetic field therapy is mainly used as one of many elements of complex rehabilitation.
Aim of the study. The aim of the study was to evaluate the effect of a series of low-frequency magnetotherapy procedures on the limitation of mobility of the lumbar spine, as well as to determine whether the value of BMI and the age of patients affect the obtained result of the mobility range.
Material and methods. 40 people aged 30 to 71 were examined. The mobility was measured on the first and last day of the therapy using a modified fingertip-to-floor test. It was a randomized, single-blind study. Low-frequency magnetotherapy was applied in group A and simulation of the procedure in group B. Statistical analysis was conducted in the Statistica 12 programme.
Results. Differences in results obtained before and after the series of procedures in particular groups of patients were statistically insignificant (p=NS).
Conclusion. Low-frequency magnetotherapy does not affect the mobility range of the lumbar spine. The value of the body mass index has a slight influence on the range of movements, and also there is no relation between the age of the participants in the study and the range of mobility of a given section of the spine.
