Primary dysmenorrhea is a common condition that significantly affects young women's quality of life. Traditional Chinese Medicine (TCM) acupoint interventions are widely used for symptom relief; however, standardized fixed-acupoint approaches often overlook individual meridian status variations.
This pilot study aims to evaluate the feasibility, preliminary efficacy, and physiological responses of an individualized meridian-guided intervention for primary dysmenorrhea in females aged 18-30. Utilizing non-invasive skin electrical resistance measurements (AETOSCAN) to assess baseline meridian energy status, eligible dysmenorrhea participants will be randomized into two parallel arms: an individualized meridian-guided intervention group and a standardized fixed-acupoint group. Interventions will be administered twice weekly over a 4-week cycle. The primary outcomes focus on changes in pain severity (VAS), menstrual distress scores (MDQ), and objective meridian electrical characteristics.
20 female participants with a history of primary dysmenorrhea symptoms.
20 healthy female controls without significant dysmenorrhea symptoms.
Age Range: Females aged 18-30 years.
Menstrual Regularity: Regular menstrual cycles, defined as a cycle duration of 21-35 days.
History of major gynecological disorders.
Confirmed diagnosis of structural or organic gynecological conditions, including endometriosis, uterine fibroids, or polycystic ovary syndrome (PCOS).
Long-term use of medications that affect the menstrual cycle.
Currently undergoing hormonal therapy or long-term administration of analgesics.

Change in Dysmenorrhea Pain Severity via Visual Analog Scale (VAS)
The Visual Analog Scale (VAS) is a 0-100 mm continuous scale used to measure subjective menstrual pain severity (0 = no pain, 100 = worst imaginable pain). Higher scores indicate greater pain intensity. Time Frame: Baseline (Pre-treatment), Mid-treatment (Week 2 of intervention), and Post-treatment (Week 4, immediately following intervention completion).
Change in Menstrual Distress Symptoms via Moos Menstrual Distress Questionnaire (MDQ Form C)
The MDQ Form C consists of 46 items across 8 subscales assessed on a 5-point Likert scale (0 = no symptom to 4 = severe symptom). Total scores range from 0 to 184, with higher scores reflecting greater menstrual distress.
Change in Meridian Electrical Resistance Profiles
Objective skin electrical resistance (in microamperes, µA) measured across twelve primary meridian Yuan-Source points using the AETOSCAN system to assess systemic physiological energy shifts.
