About this trial
Primary dysmenorrhea is a highly prevalent condition among young women and is associated with significant pain, reduced quality of life, and academic absenteeism. Although non-steroidal anti-inflammatory drugs are commonly used, many women seek non-pharmacological alternatives due to limited effectiveness or adverse effects. Emerging evidence suggests that altered pelvic neurodynamics may contribute to dysmenorrheic pain.
This randomized controlled trial aims to evaluate the effectiveness of external pelvic nerve mobilization in reducing menstrual pain and associated symptoms among university women with primary dysmenorrhea. Participants aged 18-30 years will be randomly allocated to receive either external pelvic nerve mobilization or a sham manual therapy intervention across three consecutive menstrual cycles. Outcomes will include pain intensity, menstrual distress, quality of life, pelvic tenderness, analgesic consumption, and academic absenteeism.

Treatments tested in this trial
External Pelvic Nerve Mobilization
Other interventionParticipants will receive a standardized, protocol-driven external neurodynamic mobilization intervention specifically designed to target the lumbosacral plexus and pudendal nerve pathways. Unlike general pelvic manual therapy or routine neural mobilization techniques typically used in musculoskeletal physiotherapy, this intervention incorporates: A predefined sequence of graded neurodynamic maneuvers developed exclusively for this study, combining individually titrated sliders and tensioners based on the participant's symptom irritability and neurodynamic response. Non-internal, purely external application, ensuring a consistent, reproducible method across participants while avoiding variability associated with internal pelvic techniques used in other women's health studies
Sham Mobilization
Other interventionParticipants will receive non-therapeutic light manual contact over the lumbosacral and pelvic regions without neural gliding, joint movement, or tissue mobilization. Session duration and therapist interaction will match the intervention group.
Treatment groups
Trial outcomes
Primary outcomes
Menstrual pain intensity
Menstrual pain intensity will be assessed using a 10-cm Visual Analog Scale (VAS). Participants will rate their average menstrual pain on a scale ranging from 0 to 10, where 0 = no pain and 10 = worst imaginable pain. Higher scores indicate greater pain intensity.
Secondary outcomes
Analgesic consumption
Analgesic consumption will be measured as the total number of analgesic doses consumed for menstrual pain management. Participants will record the type and number of doses taken during menstruation. Higher values indicate greater medication use.
Academic absenteeism
Academic absenteeism will be assessed as the total number of hours missed from academic activities due to menstrual pain, as self-reported by participants. Higher values indicate greater absenteeism.
DAILY RECORD OF SEVERITY OF PROBLEMS
Menstrual-related symptoms will be assessed using the Daily Record of Severity of Problems (DRSP) questionnaire. The DRSP evaluates physical, emotional, and behavioral symptoms on a 6-point Likert scale (1 = not at all to 6 = extreme), with higher scores indicating greater symptom severity.
