About this trial
This randomized controlled trial aims to investigate the effects of abdominal muscle strengthening exercises using a stabilizer pressure biofeedback device on menstrual symptoms and abdominal muscle strength in young women with primary dysmenorrhea. Primary dysmenorrhea, characterized by painful menstrual cramps without underlying pelvic pathology, is common among women of reproductive age and can negatively affect quality of life.
In this study, 58 female participants aged 18-25 with regular menstrual cycles and a Visual Analog Scale (VAS) pain score of ≥4 will be randomly assigned to either an intervention group or a control group. The intervention group will perform abdominal strengthening and stretching exercises guided by a stabilizer pressure biofeedback device, three times per week for 6 weeks (excluding menstruation weeks).
The main outcomes include menstrual symptom severity (assessed by the Menstrual Symptom Scale), pain intensity (VAS), and abdominal muscle strength (measured using the stabilizer pressure biofeedback device). The results will help determine whether targeted abdominal muscle training can reduce menstrual symptoms and improve muscle strength in women with primary dysmenorrhea.

Abdominal Muscle Strengthening Exercises with Stabilizer Pressure Biofeedback
BehavioralA supervised exercise program designed to strengthen abdominal and lumbar muscles, incorporating the use of a stabilizer pressure biofeedback device to enhance activation of deep stabilizing muscles such as the transversus abdominis. The program is delivered three times per week for 6 weeks (excluding menstruation weeks) and includes mobility, stretching, and strengthening exercises.

Trial outcomes
Primary outcomes
1
Menstrual Symptom Severity
Change in menstrual symptom severity as assessed by the Menstrual Symptom Scale (MSS). The MSS consists of 22 items scored on a 5-point Likert scale, with higher scores indicating more severe symptoms.
Time frame
Change from Baseline (Week 0) to Post-intervention (Week 8)2
Pain Intensity
Visual Analog Scale 0-10 cm (0 = no pain, 10 = worst pain). Outcome is mean change from baseline to Week 8.
Time frame
Change from Baseline (Week 0) to Post-intervention (Week 8)3
Abdominal Muscle Activation/Strength (Pressure Biofeedback)
Abdominal muscle activation measured with a Stabilizer Pressure Biofeedback Unit (mmHg). Lower pressure during correct drawing-in reflects better transversus abdominis activation. Outcome is change from baseline to Week 8
Time frame
Change from Baseline (Week 0) to Post-intervention (Week 8)Locations
