Ultrasonographic Evaluation of Abdominal Muscle Thickness Symmetry and Correlation With Pulmonary Function

Study Overview
=================
Brief Summary
-----------------
We aimed in this study: To compare the ultrasonographic measurements of the abdominal muscles thickness symmetry in patients with adolescent idiopathic scoliosis (AIS) and adolescent healthy individuals To investigate the effect of measured thickness and symmetry on pulmonary function test.

Detailed Description
-----------------
This cross-sectional,case-control clinical study included 40 patients diagnosed with AIS and 40 age and gender -matched healthy individuals. AIS group was evaluated for localization of curvature and degree of curvature. Ultrasonographic measurements and were performed of bilaterally abdominal muscle thickness in both groups. Spirometry evaluation was performed in both groups. Intragroup and intergroup data were compared.
