Background. Earlier we reported that in children with spastic forms of cerebral palsy (SFCP) after two-week course of rehabilitation by Kozyavkin© method the hand function tests changed ambiguously and such a variety of changes is due to differently directed changes in the background activity of the nerve centers. Aime: to identify the peculiarities of changes in the parameters of EEG, HRV and GDV in children with favorable and unfavorable changes in the parameters of the functions of the hands. Material and research methods. The object of observations were 14 children (6 girls and 8 boys) aged 8÷15 years with SFCP. State motor development at GMFCS was on II÷IV level. Functional status of the hand with MACS was at II÷III level. The estimation of hand function carried out by Dynamometry (D), Box and Block Test (BB) and Nine Hole Peg Test (NHP). We registered also components of muscular tone by device “NeuroFlexor” (Aggero MedTech AB, Sweden), HRV and EEG parameters simultaneosly by hardware-software complex “Cardiolab+VSR” and “NeuroCom Standard” respectively (KhAI Medica, Kharkiv, Ukraine) as well as GDV parameters by “GDV Chamber” (“Biotechprogress”, St-Pb, RF). Results. The method of cluster analysis retrospectively highlighted two distinct groups-clusters. In 9 children, rehabilitation led to favorable changes in the parameters of the function of the hands, while in 3 children they turned out to be unfavorable. The method of discriminant analysis revealed that unfavorable changes are accompanied by a decrease in the asymmetry of the θ- and δ-rhythms, the spectral power density (SPD) of β-rhythm in loci F8 and Fp1, instead, it increases in loci O1 and T3, leading to left-sided lateralization of the β-rhythm. At the same time, the SPD of the α-rhythm in locus O1 and the θ-rhythm in locus F4 rises as well as its Deviation. These changes in the EEG are accompanied by a reduction in vagalis and an increase in sympathetic tones. Among the GDVs parameters, an increase in the area of the GD Image in the frontal projection, coupled with a decrease in its Entropy in the frontal and left projections, was found. Instead, favorable changes in the parameters of the hand function are accompanied by opposite changes in the listed EEGs, HRVs and GDVs parameters or their absence. Conclusion. Among 14 observed children with spastic forms of cerebral palsy caused by Kozyavkin© method changes in functional tests of hand are favorable in 11. Adverse changes in 3 children are accompanied by characteristic changes in a number of EEGs, HRVs and GDVs parameters, which in the long run will be corrected by electrostimulation of the corresponding nervous structures.

Set the level of neural development, psycho-physiological functions in highly skilled volleyball players. Defined technical and tactical preparedness highly skilled volleyball players in the competitive period of the annual cycle of training. The study involved six masters of sport and 8 candidates for the master of sports. That the quality of play activities and the successful execution of technical elements depend on functional mobility, strength and reactivity of nerve processes, associative thinking, memory and attention. The results, which may have a prognostic value. It is shown that the neurodynamic functions are genetically determined. It is recommended to use them for the initial recruitment and selection stages for sports improvement. The necessity influence the types of thinking, memory and attention in the training process of volleyball players.

EFFECT OF SPINE BIOMECHANICAL CORRECTION KOZYAVKIN’s METHOD (INRS) ON COMPONENTS OF MUSCLE TONE IN CHILDREN WITH SPASTIC FORM OF CEREBRAL PALSY AND ITS POSSIBLE PREDICTION VI KOZYAVKIN, NV KOZYAVKINA, OV KOZYAVKINA, МS GORDIYEVYCH, VI LYSOVYCH, ТB VOLOSHYN, ІL POPOVYCH, W ZUKOW International Clinic of Rehabilitation, Truskavets’, Ukraine center@reha.lviv.ua Faculty of Physical Education, Health and Tourism, Kazimierz Wielki University, Bydgoszcz, Poland w.zukow@ukw.edu.pl Abstract A clinical-physiological observations in 29 children aged 7÷16 years with spastic forms of cerebral palsy. State of Gross Motor Function was 1÷4 levels at GMFCS, the functional state of the hand (usually the left ) was 1÷4 levels at MACS, hand spasticity estimated in the range 0÷2 on a scale Åshworth (ASS). Neural component of muscle tone (N), registered device Neuroflexor, was in the range 0,48÷18,08, elastic component (E) ranging -1,80÷4,36, and its viscous component (V) ranging -0,80÷0,73. We found a strong correlation between N and ASS (r=0,74), GMFCS (r=0,66), MACS (r=0,66), whereas the correlation of these parameters E on the verge of significance (r=0,36; 0,32, 0,34), and V all with their not related (r=0,14; 0,00; -0,15). After 10-15 min after the first spine biomechanical correction Kozyavkin’ method N in 17 children decreased from 7,6±1,1 by 3,4±0,7 (p
