Effects of the Direction of the Curve in Adolescent Idiopathic Scoliosis on Postural Balance during Sitting

چکیده
Improper postural alignment and trunk stability caused by idiopathic scoliosis may affect postural balance pattern during sitting. In this study, we conducted pressure data analysis for evaluation of postural balance in patients with idiopathic scoliosis by using pressure sensor system. Subjects were divided into three groups: a control group, scoliosis with left convex side of the curve group, and scoliosis with right convex side of the curve group. Subjects were instructed to sit on pressure sensor system which was located on the unstable board for 30 seconds. Pressure distribution data were subdivided into two regions of masks and analyzed for maximum force, peak pressure, and contact area. There were significant differences in pressure distribution pattern between scoliosis patients groups according to the direction of the curve during sitting. From these results, it was concluded that idiopathic scoliosis cause postural asymmetry during sitting. Furthermore, pressure sensor system can be utilized to detect asymmetrical balance and postural change of patients with idiopathic scoliosis for individuals.

Effect of a Long-Term Corrective Exercises With Using Brace on Cobb Angle and Postural Control of a Girl With Adolescence Idiopathic Scoliosis
Purpose: Scoliosis is a three-dimensional deformity of the spine in which the resulting imbalance accompanied by the changes in muscle and nervous components can harm the postural control. Various treatments have been suggested so far to correct scoliosis, in which using corrective exercises along with brace are essential to limit the growing curvature, improve spine stability and postural cont...

Abnormal lateral curvature of the spine may affect postural balance pattern in static and dynamic condition. Previous studies demonstrated asymmetrical balance patterns of adolescent patients with idiopathic scoliosis during sitting and walking. However, pressure distribution data have been rarely used to analyze asymmetrical postural pattern of scoliotic patients. In this study, pressure data ...

BACKGROUND The spinal curvature in patients with Adolescent Idiopathic Scoliosis (AIS) causes an asymmetry of upper body postural alignment, which might affect postural balance. However, the currently available studies on balance in AIS patients are not consistent. Furthermore, it is not known whether potential deficits are similar between patients with single and double curves. Finally, the ef...
