Study Details

Study Description

Brief Summary

Systemic arterial hypertension is a disease characterized by high blood pressure levels. It has a high prevalence, is a precursor of cardiovascular diseases, resulting in high costs to the health system and increased mortality. Transcutaneous electrical nerve stimulation (TENS) is a low-frequency pulsed electrical current widely used for analgesia. Recently, it has been proposed as a non-pharmacological strategy for blood pressure control. The aim of this study is to verify the effect of low-frequency TENS when applied in different anatomical sites on blood pressure, autonomic control and endothelial function in hypertensive patients.

Detailed Description

Systemic arterial hypertension is a disease characterized by high blood pressure levels. It has a high prevalence, is a precursor of cardiovascular diseases, resulting in high costs to the health system and increased mortality. Transcutaneous electrical nerve stimulation (TENS) is a low-frequency pulsed electrical current widely used for analgesia. Recently, it has been proposed as a non-pharmacological strategy for blood pressure control. The aim of this study is to verify the effect of low-frequency TENS when applied in different anatomical sites on blood pressure, autonomic control and endothelial function in hypertensive patients. For this, patients will be randomized into 4 groups: group 1 (cervical stimulation), group 2 (plus cervical stimulation ), group 3 (renal stimulation), group 4 (control). Group 1 will receive TENS in the cervical paravertebral region; group 2 will receive stimulation in the cervical paravertebral region, ear lobe, wrist and ankle. Group 3 will have the anatomical region of the kidneys stimulated. Group 4 will not receive any intervention. All the treated patients will receive 30 minutes of stimulation per session, regardless of group allocation. Ten applications will be carried out over the course of a month.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Cervical stimulation group

TENS will be applied for 30 minutes with a frequency of 5 Hz, pulse width of 200 µs and sufficient intensity to reach the sensory threshold. Ten sessions will be performed over four weeks.

Other: TENS - Cervical stimulation group
TENS will be applied bilaterally through self-adhesive electrodes in the cervicothoracic ganglionic region, located between the C7 and T4 vertebral processes.

Experimental: Plus cervical stimulation group

TENS will be applied for 30 minutes with a frequency of 5 Hz, pulse width of 200 µs and sufficient intensity to reach the sensory threshold. Ten sessions will be performed over four weeks.

Other: TENS - Plus cervical stimulation group
TENS will be applied bilaterally in the cervicothoracic ganglionic region, located between the C7 and T4 vertebral processes, on the earlobe, on the wrists and ankles simultaneously.

Experimental: Renal stimulation group

TENS will be applied for 30 minutes with a frequency of 5 Hz, pulse width of 200 µs and sufficient intensity to reach the sensory threshold. Ten sessions will be performed over four weeks.

Other: TENS - Renal stimulation group
TENS will be applied through self-adhesive electrodes in the abdomen (anatomical region corresponding to the kidneys) and dorsal region at the level of the 10th thoracic vertebra.

No Intervention: Control group

This group will not receive any treatment with electrical stimulation.

Outcome Measures

Primary Outcome Measures

  1. Systolic blood pressure [Baseline and after 4 weeks]

    Systolic blood pressure assessed by ambulatory blood pressure monitoring (ABPM)

  2. Diastolic blood pressure [Baseline and after 4 weeks]

    Systolic blood pressure assessed by ambulatory blood pressure monitoring (ABPM)

Secondary Outcome Measures

  1. Autonomic control [Baseline and after 4 weeks]

    Autonomic control assessed by analysis of heart rate variability by frequency meter
