Authors of the published study randomly assigned 305 participants to wear an ionized bracelet for 28 days and another 305 participants to wear a placebo bracelet for the same duration.
The study volunteers were men and women 18 and older who had self-reported musculoskeletal pain at the beginning of the study. Neither the researchers nor the participants knew which volunteers wore an ionized bracelet and which wore a placebo bracelet. Bracelets were worn according to the manufacturer's recommendations. Both types of bracelets were identical and were supplied by the manufacturer, QT, Inc.
Participants self-reported their pain for each location where they felt it with a score of 1 to 10 before wearing a bracelet. They self-reported their pain again after wearing a bracelet for one day, three days, seven days, 14 days, 21 days and 28 days. Researchers were interested in both the change in the self-reported pain score for the location of greatest pain and the change in the sum of the pain scores for all self-reported painful locations.
Both groups reported significant improvement in pain. However, researchers found no difference in the amount of self-reported pain relief between the group wearing the ionized bracelets and the group wearing the placebo bracelets. The study authors conclude that the equivalent, subjective improvement in pain scores calls into question the true benefit of using an ionized bracelet.
Principal investigator Dr. Robert Bratton, from the Department of Family Medicine, says the study was important because so many patients are interested in alternative medicine. "We need to look at what our patients are doing for their various problems,
