Evaluation of psychomotor integration parameters with KID-3 device for prenozological diagnostics of motor disorders in the late ontogenesis

Abstract

Psychomotor coordination parameters (speed, accuracy and smooth motion, the latent period of simple
sensorimotor reaction to the light stimulus) in the late ontogenesis studied in a sample of 636 healthy subjects (men
and women) aged 22 to 90 years. As a comparison group adolescents and young people aged 16-20 years were
used. It was shown that from 22 to 90 years there is an increase in the share of people experiencingminor difficulties
in coordinating the work of the perceived visual and motor systems, as well as voluntary attention. At the same time
the share of people with smoother movements and a faster response to light stimulus than in adolescence is increasing,
suggesting incomplete maturation of functional neurophysiological data systems to 20 years. The negative
trend was revealed in precision movements: an increase in the proportion of subjects with a slight decrease in
the accuracy of movement after 35 years, and with a significant decrease in this indicator since 45 years In the age
of 70 years and older only 2 options assessment by mistake movements were recorded — normal and substantial
above normal. It is proposed to use a method of estimating the parameters of instrumental psychomotor integration
with KID-3 device for the early preclinical diagnostics of age-dependent extrapyramidal disorders.
