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.\n\nIn 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).\n\nThe 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.",[57,58,59],"Menstrual Pain","Menstrual Disorders","Muscle Strength",[61,62,63],"Primary Dysmenorrhea","Abdominal Muscle Strengthening","Stabilizer Pressure Biofeedback","NOT_YET_RECRUITING","2025-08-12",{"date":67,"type":68},"2025-08-19","ACTUAL",{"date":70,"type":51},"2025-08-13",{"date":72,"type":51},"2025-09-25",{"name":5,"class":6}]
