Does Magnetic Therapy really work or is just a placebo effect?
In 2006, the WHO (World Health Organisation) issued a 350-page report summarising the known effects and mechanisms of interaction of static magnetic fields on animals, humans, and individual cellular processes. The report details comprehensive recommendations for continued high-priority research into the physical and behavioural effects of magnetic fields.
With complete conviction they concluded that the success of magnetic therapy was not due to a placebo efect.
The primary contributing factor to placebo effect in magnetic field studies is poor study design.
It's often incredibly easy for participants to realise whether they have a real or fake magnet. This makes it difficult to apply conventional medicine's double-blind research method when studying magnetic therapy.
In addition, some studies use magnetic fields that are too weak to have any significant biological effect. Others mistakenly have external factors that also influence results.
Today, a more thorough approach tends to be used. Researchers have an increased understanding of the importance of magnetic field strength, exposure time, polarity, and placement - leading to more accuarte findings.
The major evidence that refutes a placebo effect comes from studies conducted with animals, and lab experiments on cells and tissue samples. With this type of research, there is no evidence of a placebo effect.
For example when treating horse injuries with magnetic therpay the horse does not "know" they are being treated, and cannot expect a certain outcome. And differences in cellular and biological activity can therefore be accurately measured.
Static magnetic field research has recorded specific changes in capillary blood vessel dilation and microcirculation, bone mineral density, muscle twitch, and nerve transmission - to name but a few!
