The present study aims to verify the analgesic potential of a new methodological proposal for application for transcutaneous electrical nerve stimulation (TENS interactive) using patients with primary dysmenorrhoea and compare it with placebo in a randomized double blind study with convenience sample.
The denouement will be the intensity of pain from visual analogue scale.

In the active group there was only one application with interactive TENS (n = 42) with the final parameters of frequency between 90 and 150pps and pulse duration between 300 and 400μs and intensity level of tolerance, lasting 35 minutes.
In the placebo group, there was a simulated single application, following the same procedures as the active TENS group, also for 35 minutes.
measure the pain threshold, used to Visual Analogue Scale (VAS)before and after application
To assess pain intensity, will be used to Visual Analogue Scale (VAS), Assessments with EVA are performed before and after treatment of interactive TENS (proposed method). All selected volunteers were subjected to an application of TENS (active or sham) in a single menstrual cycle.
Time frame: participants will be monitored for 24 hours
duration of analgesia after application
check the duration of analgesia after application of interactive TENS (proposed method)
Time frame: 1 week
