Is exercise a safe and effective treatment for primary dysmenorrhea?
Low-intensity exercise, such as stretching or core strengthening, and high-intensity exercise, such as Zumba or aerobic training, improve menstrual pain intensity compared with no exercise (standardized mean difference [SMD] = −1.86; 95% CI, −2.06 to −1.66; nine randomized controlled trials [RCTs]; n = 632).1 (Strength of Recommendation [SOR]: B, based on inconsistent or limited-quality patient-oriented evidence.) It is unclear whether any one type of exercise is superior to another at improving overall menstrual symptoms, mental quality of life, or physical quality of life. (SOR: B, based on inconsistent or limited-quality patient-oriented evidence.) The evidence is insufficient to draw any conclusions about adverse effects. Also, there is not enough evidence to determine the benefit or harm of exercise compared with nonsteroidal anti-inflammatory drugs (NSAIDs) or oral contraceptives. (SOR: B, based on inconsistent or limited-quality patient-oriented evidence.)
Primary dysmenorrhea is defined as menstrual pain without known pelvic pathology. It is the most commonly reported menstrual symptom among young women, occurring in about 71% of those younger than 25 years, typically beginning six to 12 months following menarche.1,2 Allopathic treatment options include NSAIDs, none of which have been shown to be superior to another. Combined hormonal, implantable, injectable, or hormone-releasing intrauterine contraceptives are also effective options. Exercise has long been recommended as a low-risk adjunct, and this review evaluated the effectiveness of exercise for treating primary dysmenorrhea.3
This Cochrane review included 12 trials with 854 patients in the subjective review and 10 trials with 754 women in the meta-analysis; participants had regular menses and a diagnosis of primary dysmenorrhea.1 Women 18 to 43 years of age (mean age = 25 years)
