About this trial
This randomized, sham-controlled trial aims to evaluate the effects of self-administered acupressure on menstrual pain severity and premenstrual symptoms in women aged 18-30 years with primary dysmenorrhea. Participants will be randomly assigned to either a self-acupressure intervention group or a sham self-acupressure control group. The intervention will be applied during the premenstrual and menstrual periods over approximately six months. The primary outcome is the change in menstrual pain severity, and secondary outcomes include changes in premenstrual symptom severity, analgesic use, and menstruation-related activity limitation.

Treatments tested in this trial
Self-Acupressure
Other interventionParticipants receive structured training in self-administered acupressure at predefined acupoints (SP6, CV4, ST36, and LV3). Training is provided face-to-face at baseline. Participants are instructed to apply acupressure using moderate, comfortable, non-painful pressure during the premenstrual phase and the first days of menstruation across approximately six consecutive menstrual cycles.
Sham Self-Acupressure
Other interventionParticipants receive structured training in sham self-acupressure matched to the experimental intervention in terms of training format, session duration, frequency, and pressure intensity. Sham acupressure is applied at non-acupoint locations adjacent to the same anatomical regions as the experimental points, using moderate, comfortable, non-painful pressure during the premenstrual phase and the first days of menstruation across approximately six menstrual cycles.
Treatment groups
Trial outcomes
Primary outcomes
Change in menstrual pain severity
Change in menstrual pain severity measured using a visual analog scale (VAS, 0-10), where higher scores indicate more severe pain. The primary outcome is defined as the change in mean VAS score from baseline to the end of the 6-month follow-up period.
Secondary outcomes
Change in premenstrual symptom severity
Change in premenstrual symptom severity assessed using a validated premenstrual symptom scale. Higher scores indicate greater symptom severity. Change is defined as the difference between baseline and end-of-study scores.
Analgesic use during menstruation
Use of analgesic medication during menstruation, recorded as the number of days and/or doses of analgesic intake per menstrual cycle.
Menstruation-related absenteeism
Number of school or work days missed due to menstrual pain or premenstrual symptoms, self-reported by participants.
Other outcomes
Intervention adherence
Adherence to the self-acupressure protocol, calculated as the percentage of completed sessions out of the total prescribed sessions based on participant logs.
Participant satisfaction with the intervention
Participant-reported satisfaction with the intervention assessed using a single-item numeric rating scale ranging from 0 to 10, where higher scores indicate greater satisfaction.
