Primary Outcome Measures :
  1. Change of VAS before and after application of machine [ Time Frame: Immediately before application of machine and 20minutes after application of machine ]
    Measure the change% of VAS between before application of machine (T0) and 20 minutes after application of machine (T20) in every episode of dysmenorrhea during 1 menstrual cycle The mean of change% of VAS is primary outcome measure

Secondary Outcome Measures :
  1. BPI score [ Time Frame: 2nd day of menstrual cycle ]
    Brief Pain Inventory score
