بررسی اثر دستکاری سیستم دهلیزی در تعادل دینامیکی بیماران ایدیوپاتیک اسکولیوسیز تحت ورزش درمانی در مقایسه با بیماران بدون رژیم درمانی و افراد سالم

The mechanism of the neuromuscular system’s disorders in Adolescent Idiopathic Scoliosis (AIS) are not well known. The objectives of this study were to assess the dynamic balance of the AIS patients and the influence of exercise therapy on patients' dynamic balance.           Eleven teenager scoliotic subjects after three months exercise therapy, nine similar patients without therapy and 13 healthy age matched subjects as control group were studied. Using dynamic stability platform, the deviation of COG of subjects in different positions, including up right standing, standing with head flexion and standing with head hyper extension were measured.  The tests were repeated in both lose and stable condition of the foot platform.           Results showed that the stability of the foot platform resulted in COG's deviation by 1.13± 0.08 in all subjects. Dynamic balance of scoliotic patients without treatment was similar to that of the normal subjects. While, exercised patients had less COG deviation than the other groups. The change in head position increased the COG deviation by 2.5 times in control and non-exercised patients and 1.5 times in exercised patients.            The dynamic balance in scoliosis was not affected. Exercise improved    the dynamic balance in scoliotic subjects. Exercise therapy is recommended to improve the proprioceptives function.
