Recovery of dynamic balance following external posture disturbance in children with idiopathic scoliosis
Journal Title: Ortopedia Traumatologia Rehabilitacja - Year 2006, Vol 8, Issue 3
Abstract
Background. The aim of this study was to attempt the implementation of the method of mathematical modelling for motor properties estimation in children with idiopathic scoliosis on the process of keeping the balance in a standing position in the presence of mild disturbances.Material and methods. 42 children with idiopathic scoliosis (13-18 yr) and 40 healthy children were included into the study. Stabilography method was used to estimate body balance and the COP time series were recorded for subsequent analysis. Motor parameters of the evaluated individuals were determined based on the coefficient values of equation assessed through mathematics model.Results. The analysis of obtained calculated results showed that there are significant differences in meandered reaction induced by balance disturbation in a standing posture in evaluated patients. In scoliosis group there was a bigger loss of balance than in healthy children.The speed of loosing of balance after its deviation was slower and was dependent on the magnitude of the curvature angle. The bigger the angle values of the curvature the slower is the process of balance loss and at a lower speed and acceleration. And the time required for regaining the posture is prolonged.Conclusions. Standing posture of children with lateral curvature of the spine is more susceptible to balance disturbances and is characterised by worse stability. The reaction of nervous system to balance disturbances in scoliosis is visibly delayed and is characterised by lower impulsiveness.
