The exposure of the joints to ultrasound and sinusoidal modulated currents in combination with radon baths proved highly effective in slowly progressive juvenile rheumatoid arthritis of the first degree of activity.

Sociological study showed that 67.5% of respondents assessed their health status as satisfactory, 22.7% as poor, and 9.8% as good or quite satisfactory. Men are three times more often satisfied with their health status than women, and women almost three times more often consider their health poor. The characteristics of good health decreased almost twofold (1.9) over the last decade, this value for women is 2.8 times, while the values indicating deterioration of health status notably increased. In general, poor health is 1.7 times more frequent, judging from respondents' estimations. Self-assessment of the health status depends on respondent's age, education, and social status. The respondents consider that medical care should be free of charge and available. Only 4.7% of respondents admit paid care as regards additional specialized service, 92.7% of respondents wish to be free to select their doctor.

Thymus area was exposed to laser radiation in 180 Wistar male rats. Intact animals experienced a stress response to a single laser procedure (a rise in the levels of hydrocortisone, a fall in those of insulin, triiodothyronine and thyroxine). Longer exposure to laser radiation caused a break of the hydrocortisone mechanism. Similar effects were seen in the course exposure. The immune system was unchanged. In adjuvant arthritis laser radiation induced similar hormonal shifts and additional suppression of immunity. In 82 children with active juvenile rheumatoid arthritis laser therapy produced an insignificant effect, while in adults with moderate rheumatoid arthritis the response was good.

138 children with juvenile rheumatoid arthritis were exposed to EHF treatment. Three regimens of the microwave therapy were tested. The best results were achieved at the exposure of the thymic acupuncture points and most affected joint. Combination of microwave therapy with radon or effervescent sulfurated hydrogen baths is also recommended.

Children suffering from juvenile rheumatoid arthritis (JRA)(n-132) were exposed to low-frequency variable magnetic field. Therapeutic response registered consisted of analgetic and anti-inflammatory effects most pronounced in 14-19 mT regimen. The addition of radon baths to the above exposure resulted in higher effectiveness of the treatment due to involvement of pathogenetic JRA mechanisms.
