METHOD FOR PRE-NOSOLOGY DIAGNOSIS OF THE STATE OF THE HUMAN AUTONOMIC NERVOUS SYSTEM Russian patent published in 2022 - IPC A61B5/24 A61B5/291 H01L41/04 

FIELD: medicine.

SUBSTANCE: invention relates to medicine and can be used for pre-nosology diagnosis of the state of the human autonomic nervous system. Two piezoelectric sensors of mechanical microvibrations are applied on the left and right in the area of parietotemporal leads. One frame of microvibrations with a duration of 163 seconds is recorded in the 0.13 to 27 Hz frequency band. The frequency harmonics for each hemisphere of the brain are subjected to spectral analysis. Spectral harmonics in the 2 to 16 Hz frequency band are isolated for the left hemisphere, summed, and averaged by amplitude. Spectral harmonics in the 0.17 to 1.54 Hz frequency band are isolated for the right hemisphere, summed, and averaged by amplitude. The autonomic index (AI) is obtained, being the ratio of the average sum of harmonics of the left hemisphere and the average sum of harmonics of the right hemisphere. At the AI value of 1.0 to 2.5, normotonia is determined. The AI value of 0.9 to 0.5 corresponds to minor, and less than 0.5 - pronounced vagotonia. The AI value of 2.5 to 4.5 corresponds to minor, and more than 4.5 - pronounced sympathicotonia.

EFFECT: method ensures timely, informative, and accurate assessment of the state of the human autonomic nervous system.
