Hypertension is considered a serious public health problem. The imbalance in autonomic nervous system (ANS) activity is one of the main triggers in the development and maintenance of hypertension. The non-pharmacological management of this disease is an important resource, especially in refractory hypertensive patients or in hypertensive crises, where the pharmacological treatment does not present an efficient response. It is known that transcutaneous electrical nerve stimulation (TENS) is capable of modifying the autonomic balance, however, the effects of Interferential electrical stimulation (IES) on this system in normotensive and hypertensive volunteers are not yet known. These electrotherapeutic resources may be a non-pharmacological tool supporting the management of hypertension. The objective of this research is to study the effects of different TENS and IC parameters on cardiovascular variables of normotensive volunteers and hypertensive patients.
