Self-Acupressure for Primary Dysmenorrhea and Premenstrual Symptoms

Official title

Effects of Self-Acupressure on Primary Dysmenorrhea and Premenstrual Symptoms in Women Aged 18-30: A Randomized, Sham-Controlled, 6-Month Trial

Overview

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.

Detailed description

Primary dysmenorrhea and premenstrual syndrome are highly prevalent conditions among women of reproductive age and are associated with substantial impairment in quality of life, academic or work performance, and daily functioning. Although pharmacological treatments such as nonsteroidal anti-inflammatory drugs and hormonal contraceptives are commonly used, they may be ineffective, contraindicated, or undesirable for some individuals. Therefore, non-pharmacological, low-cost, and self-administered approaches are of clinical interest.

This study is a randomized, parallel-group, sham-controlled clinical trial designed to investigate the effectiveness of a self-acupressure protocol on menstrual pain and premenstrual symptoms. Eligible participants are women aged 18-30 years with regular menstrual cycles and clinically significant primary dysmenorrhea and premenstrual symptoms. Participants are randomized in a 1:1 ratio to either a verum self-acupressure group or a sham self-acupressure group.

The verum intervention consists of self-administered acupressure applied to predefined acupoints (SP6, CV4, ST36, and LV3), while the sham intervention uses non-acupoint locations near the same anatomical regions. Both interventions are matched in terms of training, session duration, frequency, and pressure intensity. Participants are instructed to perform acupressure daily during the premenstrual phase and on the first days of menstruation across approximately five to six consecutive menstrual cycles.

Outcome assessments are conducted at baseline and at the end of the six-month follow-up period. The primary outcome is the change in menstrual pain severity measured by a visual analog scale. Secondary outcomes include changes in premenstrual symptom severity scores, analgesic consumption, and menstruation-related school or work absenteeism. Adherence and participant-reported feasibility are also recorded. The study is conducted under minimal-risk conditions, and all participants provide written informed consent prior to enrollment.

Interventions

• Other Self-Acupressure
  Participants 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.
• Other Sham Self-Acupressure
  Participants 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.

Primary outcome measures

• Change in menstrual pain severity [Time frame: Baseline and end of 6 months (approximately 5-6 menstrual cycles)]

Secondary outcome measures (3)

• Change in premenstrual symptom severity [Time frame: Baseline and end of 6 months]
• Analgesic use during menstruation [Time frame: Assessed throughout the 6-month follow-up period]
• Menstruation-related absenteeism [Time frame: Assessed throughout the 6-month follow-up period]
