Magnetic Therapy Devices May Lack Significant Efficacy
【Takungpao News 2006-1-10】
Magnetic therapy bracelets and knee pads have become increasingly popular health products in recent years, with global annual sales reaching billions of dollars. A recent editorial in the British Medical Journal states that there is currently no scientific evidence to support the pain-relieving effects claimed by manufacturers of magnetic therapy devices, suggesting that users may be wasting their time and money.
In the editorial, American researchers Leonard Finegold and Bruce Flamm noted that many studies attempting to prove the effectiveness of magnetic therapy overlook the primary characteristic of magnets—their attraction or repulsion to metal. The perceived effectiveness of magnetic therapy devices by users may be due to the placebo effect.
According to a Xinhua News Agency report from Beijing on January 10, the article states that, theoretically, even when human tissue is exposed to the magnetic fields generated by MRI machines, these tissues remain unaffected. Therefore, it is unrealistic to claim that the magnetic fields produced by magnetic therapy bracelets have pain-relieving effects. When a magnetic therapy bracelet is brought close to common ferromagnetic surfaces in daily life, users may subconsciously feel a slight pull, which can influence their perception of pain and create an illusion. A previous study published in the British Medical Journal showed that the pain-relieving effects of magnetic therapy bracelets are likely due to the placebo effect rather than actual efficacy. The researchers noted that due to endorsements by famous athletes in advertisements for magnetic therapy devices, many people believe they are truly effective. This may lead to delayed treatment for certain conditions. Advertisements for magnetic therapy devices should inform consumers that their efficacy has not been scientifically proven. They said, "If people are still interested in magnetic therapy, it's best to buy the cheapest option, as that at least reduces the 'pain' in their wallets."
