| Abstract | Purpose: The aim of this study was the objective control of the therapeutic effect of weak pulsing magnetic fields (series of periodically repeating square pulses increasing according to an e-function, frequencies of 10, 20, 30, and 200 - 300 Hz) by means of a double-blind study on osteoarthritis of the knee. Measured parameters were the Knee Society score, pain sensation, blood count and cardiocirculatory values. Methods: 36 placebo and 35 verum test persons (all with a knee gap smaller than 3 mm) were exposed daily for 16 minutes over 6 weeks to a low frequency magnetic field (flux densities increasing gradually from 3.4 up to 13.6 [micro]T) encompassing the whole body. The last data collection was made 4 weeks after the end of treatment. Results: Principally, the statistically ensured results exclusively favour the used magnetic field therapy; by far the greatest number of at least significant differences was found at the end of the whole treatment, lasting 6 weeks. In particular, it is striking that all 4 questioned pain scales showed at least significant improvements in favour of the verum collectiveč also the walking distance was increased. As another confirmed fact, even after 4 weeks without therapy the persistence of several functional and analgesic effects could be documented. Conclusions: Predominantly, on the one hand, pain relief in osteoarthritis patients was confirmed by a double-blind trial, on the other hand, increases in mobility could be proven. Furthermore, we describe mainly the modes of action of low frequency magnetic energy and 3 physical concepts that are seen as the connecting link between electromagnetic fields coupled into connective tissue and biochemical repair and growth processes in bones and cartilage.
