Have you seen those advertisements for bracelets that
eliminate pain? These "ionized" bracelets are endorsed by celebrities and
athletes. The makers of ionized bracelets claim that the bracelets work
by balancing the body's energy or "yin and yang" and that imbalances in
yin and yang result in pain. Do these bracelets really work? Researchers
at the Mayo Clinic (Jacksonville, FL) performed some controlled
experiments to find out.
Patients who complained of pain in the neck, shoulders,
elbows, wrists, hands, back, hip, knees, ankles or feet were divided into
two groups. One group of 305 patients wore an ionized wrist bracelet;
another group of 305 patients wore a wrist bracelet that looked just like
the ionized bracelet (placebo). During the experiment, neither the
patients nor the researchers knew who was wearing an ionized bracelet or a
placebo bracelet. At the start of the experiment, the patients were asked
to rate their pain on a scale of 1 to 10, where 1 was "very little pain"
and 10 was "pain as bad as it could be." The patients also rated their
pain over the course of four weeks (on days 1, 3, 7, 14, 21, 28) after
they started to wear their bracelets.
Both groups of patients showed significant reductions in
pain. However, there were no differences in pain reduction between the
ionized bracelet group and the placebo bracelet group at any time. In
other words, wearing a fake bracelet was just as good at reducing pain as
an ionized bracelet! Before the experiment began, 80% of the patients
reported that they believed that ionized bracelets could reduce joint or
muscle pain. Therefore, it is possible that the BELIEF in the "power" of
the bracelet was responsible for the reduction of pain. It would have
been interesting if the researchers included a group of patients who did
not wear any bracelet to see how pain reports change over time.
An ionized bracelet costs between $50 and $110. According to this new
research, it may be best to keep your money in your pocket.
