Effect of acupressure at the Sanyinjiao point on primary dysmenorrhea: A randomized controlled trial

ObjectiveWe conducted this study to assess the effect of acupressure at the Sanyinjiao point on primary dysmenorrhea.MethodsEighty-six students participated in the study. All participants met the inclusion criteria. The study group received acupressure at Sanyinjiao point, while the control received sham acupressure. The severity of dysmenorrhea was assessed at the following time periods: prior to the intervention, 30 min, 1, 2 and 3 h following the intervention. Data were analyzed using SPSS.ResultsThe acupressure caused decline in the severity of dysmenorrhea immediately after intervention in both groups during their first menstrual cycle, although, there difference was not significant (p > 0.05). In addition, during the same cycle, the severity of the dysmenorrhea decreased more in study group rather than control group at 30 min, 1, 2 and 3 h after intervention (p < 0.05). During the second menstrual cycle, acupressure made dysmenorrhea reduced in both study and control groups; however, the decline was more salient among participants of the study group at all stages after the intervention (p < 0.05).ConclusionsAcupressure at Sanyinjiao point can be an effective, feasible, cost-effective intervention for improving primary dysmenorrhea.
