Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This prospective clinical trial evaluates the effects of a non-pharmacological intervention combining muscle energy technique (MET) and myofascial chain (MFC)-based pelvic stabilization training in women with primary dysmenorrhea (PD). The study aims to determine whether this combined approach can improve pelvic alignment, reduce menstrual pain, and enhance static balance. Participants are assigned to either an experimental group receiving MET + MFC-based training or a control group receiving conventional physiotherapy. Outcomes include radiographic pelvic parameters, pain intensity, and balance performance.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Primary dysmenorrhea (PD) is a common gynecological condition characterized by cyclic lower abdominal pain without an identifiable organic cause. Biomechanical factors such as pelvic misalignment and myofascial imbalance are increasingly recognized as contributing to the persistence and severity of PD.

This prospective non-randomized controlled trial investigates whether a combined intervention of muscle energy technique (MET) and myofascial chain (MFC)-based pelvic stabilization training can improve pelvic structure and reduce clinical symptoms in women with PD. Participants are women aged 18-45 years with moderate-to-severe PD and radiographic evidence of pelvic misalignment. They are assigned to one of two groups:

Experimental group: MET plus MFC-based core stabilization exercises. Control group: Interferential current therapy and deep friction massage. Interventions are administered three times per week for four weeks. The primary outcomes include changes in pelvic sagittal parameters (pelvic tilt, sacral slope, pelvic incidence), pelvic symmetry, menstrual pain (measured by VAS), and static balance (eyes-closed single-leg stance). Assessments are conducted at baseline, 4 weeks, and 12 weeks post-intervention.

The study aims to explore whether biomechanical correction of pelvic alignment contributes to pain modulation and functional improvement in women with PD, providing a basis for non-pharmacological rehabilitation strategies.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Combined MET and MFC-Based Pelvic Stabilization

Participants receive Muscle Energy Technique (MET) for iliac dysfunction and sacral torsion, plus myofascial chain-based pelvic stabilization training (curl-ups, planks, anti-rotation). 3 sessions/week, 50 minutes/session, for 4 weeks.

Group Type EXPERIMENTAL

Combined MET and MFC-Based Pelvic Stabilization Training

Intervention Type BEHAVIORAL

This intervention consisted of a combination of Muscle Energy Technique (MET) for iliac and sacral dysfunctions (20 minutes per session) and myofascial chain-based pelvic stabilization training (including curl-ups, planks, and anti-rotation exercises; 30 minutes per session), targeting pelvic alignment and neuromuscular control. Sessions were conducted 3 times per week, 50 minutes per session, for 4 consecutive weeks.

Interferential current therapy (ICT) and Deep Friction Massage (DFM)

Participants receive medium- and low-frequency electrotherapy and deep friction massage targeting the lumbar (lower back), sacroiliac, and iliac crest regions. 3 sessions/week, 50 minutes/session, for 4 weeks.

Group Type ACTIVE_COMPARATOR

Interferential current therapy (ICT)

Intervention Type DEVICE

Interferential current therapy (ICT) was applied to the lumbar (lower back), sacroiliac, and iliac crest regions, 3 sessions per week, 20 minutes per session, for 4 weeks.

Deep Friction Massage (DFM)

Intervention Type BEHAVIORAL

Deep friction massage was administered to the lumbar, sacroiliac, and iliac crest regions for 30 minutes per session, 3 sessions per week, for 4 weeks.
