Estimulação elétrica nervosa transcutânea (TENS) alivia a dismenorreia primária: estudo clínico, controlado e randomizado

Resumo (EN)

Objective – To evaluate the influence of TENS on primary dysmenorrhea. Methods – The study comprised two groups: TENS (GT) with 14 women (average age 21.57 ± 2.9 years old) and Control Group (CG) with 7 women (average age 24 ± 3.15 years old). Women were at the beginning of the menstrual cycle, between 1 and 3 days of dysmenorrhea. The GT was submitted to conventional TENS mode, 40 minutes, 120 Hz, 100 μs and amplitude at sensorial level with the channels parallel to the lumbar sacral spine (L5-S3). The GC followed the same parameters as the GT, but the intensity was increased in channels that were not positioned in the patient. To collect data related to pain was used Visual Analogue Scale (VAS). Results – The GT showed a statistically significant difference (p >0.0001) between intensity of pain before and after application of TENS, the evaluation of the EVA. In GC there was no significant difference (p> 0.05) between the intensity of pain before and after application of TENS. Conclusion – The application of TENS has decreased the primary dysmenorrhea.
