The Functional Neurometry of Nelson Alves Pereira Júnior: An Advanced Method of Mapping and Biofeedback Training of the Autonomic Nervous System Functions

Introduction: 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. Method: 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. Conclusion: Functional neurometry mainly allows the balance of the ANS, making it a protective filter of the central nervous system.
