Primary dysmenorrhea (PD) is characterised by cramping pain in the lower abdomen that occurs just before or during menstruation in women. This pain can be relieved by NSAIDS or oral cantraceptives. Unfortunately, these agents are often associated with adverse events. In this research, Hai-Yan Ba et al introduce new transcutaneous electrical nerve stimulation (TENS) therapy to provide pain relief for patients with PD.

To assess the safety and efficacy of transcutaneous electrical nerve stimulation (TENS) treatment for alleviating pain among females with primary dysmenorrhea (PD).

A total of 134 participants with PD were selected anjd categorised into sham and intervention group. Patients of sham received sham TENS and intervention group obtained TENS. Numeric Rating Scale (NRS) was used to measure the primary endpoint and the number of ibuprofen tablets taken, the World Health Organization quality of life (WHOQOL)-BREF score, adverse events, and the duration of relief from dysmenorrheal pain was taken as the secondary endpoints. 

One hundred twenty-two patients accomplished the analysis.  TENS showed a more substantial impact in pain relief about the NRS (P < .01), the number of Ibuprofen tablets taken, and duration of relief from dysmenorrheal pain as compared to the sham TENS. Although, no notable differences in the quality of life was noticed between the groups. The adverse effects profiles were also alike within the groups.

TENS was effective and safe in alleviating pain among the patients with PD.
