The study found no significant difference between devices based on their effects on pain, stiffness and physical function.“Although they are generally harmless, people with osteoarthritis should be particularly careful to spend large sums of money for magnetic therapy. Disused magnets removed from the speakers are much cheaper, but you must believe they can work.”
The test was conducted by Stewart Richmond, a researcher at the Department of Health Sciences at the University of York, said. “This is the first randomized controlled trial to show that copper bracelets are ineffective to alleviate arthritis pain”
The trial involved 45 people aged 50 or over, who were all diagnosed with osteoarthritis. Each participant was four devices in random order in a period of 16 weeks – two bands with different levels of magnetism, a strap and demagnetize a copper bracelet.
The researchers conducted the first randomized placebo against the use of copper bracelets and magnetic bracelets at a time for the management of pain in osteoarthritis – the most common form of the state.
Magnetic therapy is a rapidly growing company with worldwide sales of therapeutic devices incorporating permanent magnets, with a value of $ 4 billion.
The devices are used worldwide to help manage chronic pain associated with musculoskeletal disorders. The results of this trial conflict with those of previous studies, showing that magnetic bracelets and copper have been ineffective in managing pain, stiffness and physical function in osteoarthritis. The research was published in the latest issue of the journal Complementary Therapies in Medicine.
The study also involved researchers from the University of Hull, Durham, and the NHS.
