Current study has shown that use of magnetic insoles in shoes do not relieve the foot pain. Reporting in the current issue of Mayo Clinic Proceedings, the researchers from Mayo Clinic felt that static magnets may not be effective in relieving pains.
Searchers for the study had said adults with foot pain are likely to initiate self-treatment with magnets based on personal recommendations or belief systems, often without a specific diagnosis or prescription.
An interesting result in the study relates to "the placebo effect." Patients in studies who are given the placebo or false treatment often report improvement in their conditions when they believe they are receiving a treatment designed to provide relief.
Otherwise, the fact that magnetic and nonmagnetic insoles provided nearly identical pain relief suggests that it may have been simply the cushioning that was effective and not the magnets. In the past decade, the use of magnets for pain relief has increased substantially. Despite little scientific evidence (and lack of Food and Drug Administration approval for pain relief), many people have used magnets to relieve their pain, spending approximately $5 billion worldwide on magnetic pain-relieving devices.
