Changes in the functional status in children with cerebral palsy when performing cyclic movements

Aim. The article aims at improving functional activity in children with cerebral palsy based on the features of adaptation to cyclic motions. Materials and methods. 23 children with cerebral palsy aged from 2 to 14 years participated in the study regardless of the form of disease. Functional shifts were assessed under the effect of cyclic load on the cardiovascular system. The following methods were used for the study: heart rate variability analysis based on the changes in total power spectrum (TPw, mc2), relative values of heart rate spectrum characteristics (HF%, LF%, VLF%), and the Stress Index (SI). Results. It was established that long-term hyponesia affected negatively hemodynamics in children with cerebral palsy and contributed to a decrease in adaptation mechanisms. The initial functional status of children with cerebral palsy was characterized by low values of adaptation reserves, aerobic power, and recovery potential. Adaptive capabilities in children when growing up from 3 to 12 years decrease to asthenization. Conclusion. Motor performance is the most effective factor influencing improvement of functional capabilities in children with cerebral capabilities. The movements of the cyclic type contribute to an increase in excitability and muscle lability, as well as to the development of general endurance.
