Abstract
Current study was conducted to determine effect of pulsed electromagnetic field (PEMF) versus transcutaneous electrical Nerve stimulation (TENS) on menstrual distress of primary dysmenorrhea. Forty female diagnosed as primary dysmenorrhea with normal menstrual cycle (certified gynecologist) their ages 18_24years, 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 5April to 30 September 2021. The females were divided equally and randomly allocated within two groups of 20 per each; study group (G1) received PEMF of 50HZ and 60gauss at lumbosacral region (L4-S3) for 3 sessions per cycle for 3 consecutive cycles, each was 30minute, while female in a comfortable modified side lying with small paddings across curves, While control group (G2) 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 bilaterally 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 questionnaire (MSQ) and measurement of concentration of prostaglandins level pre and post treatment of both groups. Obtained result has revealed a statistically significant decrease in prostaglandins values, Walidd score and menstrual symptom questionnaire in both groups, as well study group (G1) revealed a statistically significant improvement at all measures than control group (G2) (p<0,001).
Conclusion: Based on the obtained study results, it’s concluded that both PEMF and TENS were effective modalities, but PEMF os more effective than TENS in treating primary dysmenorrhea
