Lee Ch et al, 2011 [multicenter randomized double-blind placebo-controlled trial; n = 104; female; from 15 to 45 years old] aimed to determine the efficacy and safety of a sericite emitting far infrared rays in the management of primary dysmenorrhea. The study was conducted over 7 menstrual cycles. The first 2 cycles served as a baseline period. Participants in the experimental group were treated with a sericite belt whereas the control group was given a placebo belt. Both groups also used a hot pack. The authors observed that severity of dysmenorrhea gradually decreased during the treatment period in both groups, with major improvements observed in the third treatment cycle. During the follow-up period, the decreased VAS score was maintained in the experimental group, whereas the VAS score gradually returned to baseline in the control group, which resulted in significant difference between the groups. The number of patients who took analgesics decreased in both groups, but the differences were not statistically significant. No serious adverse events related to wearing the sericite belt occurred. They concluded that a far infrared-emitting sericite belt with a hot pack might be used as an effective and safe non-pharmacologic treatment option for women with primary dysmenorrhea, with a prolonged effect after treatment.
