The autonomic nervous system plays an important role in regulating the physiological processes of the human organism under both normal and pathological conditions. Among the techniques used for its assessment, heart rate variability (HRV) has emerged as a simple and non-invasive measure of autonomic impulses, representing one of the most promising quantitative markers of autonomic balance, to assess ANS modulation. HR variations or variability can be measured in time and frequency domains, with specific protocols for each domain. Manual cervical vertebral therapy promotes increased range of motion in the manipulated segment and acts on neurophysiological mechanisms of pain reduction promoting adjustments in spine hypomobility that may be one of the factors that cause an increase in parasympathetic and or sympathetic tone may lead to modulation of cardiac ANS promoting hemodynamic effects on heart rate. Regardless of the type of manual vertebral therapy technique, it is observed that when acting on the cervicothoracic region, both the sympathetic and parasympathetic portion of the ANS are affected causing changes according to the technique and body region activated, certainly, future research is necessary to evaluate , in a greater number of subjects, the influence of the sympathetic and parasympathetic systems on cervical vertebral manipulation techniques.
