Features of postural control in children with severe forms of idiopathic scoliosis

Objective. The study of postural stability in children with severe degrees of idiopathic scoliosis and assessment of body balance disorders after surgical correction of spinal deformity. Material and methods. The study of 18 patients aged 14–17 years with idiopathic scoliosis of the III–IV degree with localization of the main arc according to Lenke I, III, V and VI was conducted. The vertical balance of the body was evaluated using a stabilometric platform MBN "Biomechanica" (LLC "MBN", Moscow) before and 9–10 days after the surgical correction of spinal deformity using transpedicular spinal systems. The results were compared with a stabilometric survey of 18 healthy children. Results. In patients with idiopathic scoliosis before surgery, a decrease in the stability of the vertical balance of the body, manifested by pronounced deviations from the nominal values of the stabilometric parameters, was revealed. The correlation analysis showed a pathologically strong relationship between the length L , the area S and the amplitude of fluctuations of the pressure center A in patients’ statokinesiograms compared to the group of healthy children. In the immediate postoperative period, the postural control system disorders are aggravated in patients. Conclusions. In children with severe idiopathic scoliosis, violations of the postural control system were revealed, which led to the formation of a suboptimal motor stereotype due to dysfunction of sensorimotor integration.
