Abstract
Objective. To study peculiarities of the functional state of neuromuscular system in children with grade I–II scoliosis depending on plasticity of neurodynamic processes in the central nervous system (CNS).
Material and Methods. Patients with right-sided lumbar grade I-II scoliosis aged from 15 to 18 years were examined. Functional state of cerebral cortex was evaluated by EEG of fronto- occipital lead, and that of the lumbar spine muscles — by EMG of m. erectum spinae. The effort, morphofunctional reorganization of motor units, differential diagnosis of primary muscular diseases, and dysfunction of motoneurons or their axons were determined.
Results. Groups of patients with low, moderate, and high plasticity of central mechanisms of self-regulation of functions were isolated. Findings of EMG study showed that maximum muscular effort is reached in patients with high plasticity of neurodynamic processes. The frequency of the examined muscle response varies within a small range, irrespective of the CNS plasticity.
Conclusion. High plasticity of neurodynamic processes is associated with greater number of motor units involved into motor activity, higher density of muscle fibers, greater number of phasic motor units, and lesser number of motoneurons and greater number of muscle fibers within each motor unit.
