NEURODYNAMIC PREDICTORS OF PRECISE MOTOR RESPONSE

Abstract

Aim: The article aims to identify neurodynamic predictors of precise motor response in non-athletic students. Materials and methods. Based on the percentile analysis of precise responses in 100 students (Response to a moving object test) two groups were formed: with a high (n = 23) and low level of precision (n = 25). A comparative analysis of the main indicators of nervous processes (mobility, strength and balance) was performed. Psychophysiological testing was carried out using the NS-Psychotest (Neurosoft, Ivanovo) equipment and a standard battery of tests such as “Response to a moving object”, “Eye-hand coordination test”, “Tapping test” and “Contact coordinationometry”. Statistical data processing was performed using the SPSS v. 17 with the Mann-Whitney test (U). Results. A distinctive feature of the compared groups is the average value of the response time in the Eye-hand coordination test. Integral indicators of the functional status of the central nervous system are not a criterion that determines motor response precision. The main feature that distinguishes motor responses in persons of the compared groups is the number of delayed responses (p < 0.001) and the sum of their time (p < 0.001). It was found that the high precision of motor responses was determined by the balance between excitation and inhibition against low variability of sensorimotor responses. Conclusion. The “Contact coordinationometry” and “Tapping test” are not specific for the diagnosis of neurodynamic predictors (correlates) of motor response precision but they can be used as additional methods for assessing the current psychophysiological status of a subject.
