Effect of transcutaneous electric nerve stimulation (TENS) on hormones profile in subjects with primary dysmenorrhoea - a preliminary study

Abstract

((5.27) and 56.81ng/ml ((31.86) to post treatment values of 27.33µg/dl ((5.13) and 53.23ng/ml ((37.63) respectively. However, these differences were not statistically significant (P>0.05). Pain intensity was significantly reduced comparing pre and post treatment VAS scores (P = 0.001). Conclusion:The probable mechanism by which TENS effected alterations in cortisol and prolactin levels and pain reduction in subjects with PD might be through the opioid-modulating analgesia system, which releases B-endorphins and other endogenous opiates in response to pain. This is because there is a close relationship between B-endorphin, cortisol and neurons, which secrete dopamine into the hypothalamic-pituitary-portal system.
