Are there scientific controversies associated with using magnets for pain?
Yes, there are many controversies. Examples include:
- The mechanism(s)
by which magnets might relieve pain have not been conclusively identified
- Pain relief while
using a magnet may be due to reasons other than the magnet. For example,
there could be a placebo effect or the relief could come from whatever
holds the magnet in place, such as a warm bandage or a cushioned insole.22,24
- Opinions differ
among manufacturers, health care providers who use magnetic therapy,
and others about which types of magnets (strength, polarity, length
of use, and other factors) should be used and how they should be used
in studies to give the most definitive answers.
- Actual magnet strengths
can vary (sometimes widely) from the strengths claimed by manufacturers.
This can affect scientists' ability to reproduce the findings of other
scientists and consumers' ability to know what strength magnet they
are actually using.26,31,32
