Abstract Background: Dysmenorrhea known as painful periods or menstrual cramps, the pain is commonly felt in the lower abdomen or pelvic, Backache, diarrhea, and nausea are some of the other symptoms . Symptoms usually last three days or less. Aim of Study: This study was conducted to determine effect of pulsed electro magnetic field versus Transcutaneous electrical nerve stimulation on menstrual distress of primary dysmenorrhea. Patients and Methods: Forty female diagnosed as primary dysmenorrhea with normal menstrual cycle (certified gyne-cologist) their ages 18-24 years, their body mass index (BMI) less than 29kg/m2 with no medical or psychological problems, were selected randomly from Alexandria General Hospital (Obstetrics and Gynaecology Department), from 5 April to 30 September 2021. The females were divided equally and randomly allocated within two groups of 20 per each; study (G1) group received PEMF of 50HZ and 60gauss at lumbosac-ral region (L4-S3) for 3 sessions per cycle for 3 consecutive cycles, each was 30 minute, while female in a comfortable modified side lying with small paddings across curves, While control (G2) group received TENS using 100Hz with pulse width 95 microseconds, with intensity produced a comfortable perceptible paraesthesia without muscular contraction along 30minutes while female in supine and electrodes were bilat-erally placed ~5cm laterally to midline at umbilical level, study protocol applied twice per day for first two days of menses, along two successive menses. Primary dysmenorrhea was evaluated by Walidd score, Menstrual symptom question-naire (MSQ) and measurement concentration of prostaglandins level pre and post treatment of both groups. Results: Obtained result has revealed a statistically sig-nificant decrease in prostaglandins values, Walidd score and menstrual symptom questionnaire in both groups, but study (G1) group revealed a statistically significant improvement at all measures than control (G2) group (p<0,001).
Conclusion: Based on the obtained study results, it's concluded that both PEMF and TENS were effective modal-ities, but PEMF was more effective than TENS in treating primary dysmenorrhea.
