The Functional Neurometry: An Advanced Method of Mapping and Biofeedback Training of the Autonomic Nervous System Functions (Preprint)

Abstract

BACKGROUND Functional Neurometry makes Biofeedback tools already demonstrated in the literature, such as: galvanic skin response, cardiac coherence and variability, thermoregulatory and respiratory interact with each other. OBJECTIVE The aim of this study was to report the historical and methodological aspects of the Functional Neurometry protocols. METHODS A review was made in the MEDLINE / PubMed electronic indexing database and in the Web of Science. RESULTS This method intends to synchronize the frequencies of various organs linked to the autonomic nervous system (ANS) to control anxiety. Assessment and training are organized into categories. The categories of the assessment protocol are: 1st) Anxiety Control; 2nd) Physiological Response; 3rd) Baroreflex Index; 4th) hemodynamics; and 5th) Brain Neurometry and the training protocol categories are: I) Sound Anxiety Control; II) Visual Anxiety Control; III) Emotional Variability; IV) Respiratory Amplitude and Frequency; V) Progressive Muscle Relaxation; VI) Functional Physiological Response; VII) Respiratory Functional Capacity; VIII) Heart Rate Variability and IV) Cardiac Coherence. CONCLUSIONS Functional neurometry mainly enables ANS balance.

“…ANS signals are measured by capturing low frequencies, separating them into sympathetic by means of vasoconstrictions, representing the recording of the effect of the perception of external stimuli by the frequencies 0.01 to 0.04 Hz and of the perception of internal stimuli by frequencies 0.04 to 0.20Hz, and also of the parasympathetic through vasodilation, expressed by frequencies 0.20 to 0.50 Hz. 11 The specifications of each category of the DSO analysis organized by author Nelson Alves Pereira Júnior, mentioned in the second paragraph of the introduction to this study, involving the form of capture and analysis of biological signals by each sensor regulated in algorithms organized by the Fourier Transform, are recorded in the study by Ribas et al 2 All patients were evaluated at the Instituto do Cérebro de Pernambuco (ICerPE). Before evaluation by Functional Neurometry, the following measurements were taken: weight [Kg], height [m], waist circumference [cm] and body mass index.…”

“…Baroreflex pulses can be counted in Functional Neurometry in a statistical percentage called the baroreflex index by the author and this calculation only provides assurance that functional oxygen reached the vasomotor centres in sufficient quantities, when it counts 90% or more. 2 This functioning with active and constant movement of these mechanoreceptors also seems to indicate that there is a good flow in the blood displacement also called hemodynamic at the level of blood microcirculation. 1 In the process of investigating the functioning of oxygen transport, the category entitled physiological response stands out, which also attests to the functionality of the sympathetic and parasympathetic systems made possible through the thermoregulation sensor located in the annular proximal phalanx.…”

“…1 The author organized his Functional Neurometry method in an assessment established in 3 (three) positions (dorsal position; standing up and standing) and named the categories of this initial investigative protocol: Anxiety control; baroreflex index; Hemodynamic; Physiological response and brain neurometry. 2 In the first category, entitled anxiety control, the non-cognitive response (not voluntarily controlled in a rational way) is measured, that is, the ANS response. 3 The author uses galvanic skin response sensors (dermal conductance).…”

“…4 These sensors apply a very small and imperceptible electrical voltage to the skin, specifically, on the volar surface of the index and middle fingers, where there are numerous sweat glands, allowing you to measure the impedance of the electrical current in microohm units. 2 Another relevant category of this initial psychophysiological assessment concerns the functioning of baroceptors. 5 The more the baroceptors are activated, the more functional oxygen is transported to the mitochondria, 1 especially in the places where the mitochondria are more agglomerated, which are: brain, muscles and ganglia.…”
