OBJECTIVE: Dysmenorrhea is one of the most common problems for women, especially during their reproductive age. Various studies have examined the effects of vitamins D and E and ginger supplements. This study aimed to investigate the individual effects of each of these supplements on dysmenorrhea. METHODS: This single-blind clinical trial was conducted in 2016 on students aged 18 to 25 years who complained of mild to severe dysmenorrhea. The participants were randomly assigned into 4 groups: vitamin D, vitamin E, ginger, and placebo. The effects of the supplements on the severity of dysmenorrhea were evaluated in 2 successive cycles using the visual analog scale (VAS) and a questionnaire. RESULTS: Initially, 240 female students were enrolled in the study; thereafter, 40 students were excluded from the study owing to follow-up loss. The average VAS score for dysmenorrhea in the entire study population was 7.13±0.80 before the intervention; the mean VAS score after the first and second months of supplement use was 5.37±1.51 and 4.93±1.48, respectively. The highest reduction in pain severity was observed in the ginger group (F=74.54, P<0.001). CONCLUSION: Vitamin D, vitamin E, and ginger significantly reduced the severity of dysmenorrhea, with ginger having the most significant effect followed by vitamin D and vitamin E. Given the low risk of these supplements, more studies must be conducted on their use as opposed to analgesics.

Objective: To examine the effect of acupuncture-like transcutaneous electrical nerve stimulation (ACUTENS) on labor pain in nulliparous women. Methods: This randomized clinical trial was conducted at Razi Hospital in Qazvin, Iran between January and July 2018. After the screening process, 144 out of 184 pregnant women were selected by convenience sampling and assigned to an intervention group or a control group by the block randomization method. The intervention group received ACUTENS at Hegu (LI4), Shenmen (HT7), Sanyinjiao (SP6), and Neimadian (Extra) during various stages of delivery in addition to routine labor care at the delivery room. For the control group, the same routine labor care was performed alone. The severity of pain was assessed in the two groups using the visual analog scale (VAS). The data were analyzed using R software (ver. 4.0.2) and repeated measurement analysis of variance. Results: ACUTENS reduced the mean score of pain intensity in the first stage of labor in the intervention group more than that in the control group (P<0.001). Also, the mean scores of pain intensity in the second stage of labor, episiotomy, and one hour after delivery in the intervention group were significantly lower than those in the control group (P<0.001). Conclusion: ACUTENS at Hegu (LI4), Shenmen (HT7), Sanyinjiao (SP6), and Neimadian (Extra) can decrease the intensity of labor pain in nulliparous women. It can be used as a non-pharmacological method for reducing pain in and after labor.
