Ultrasonographic evaluation of abdominal muscle thickness symmetry in adolescent idiopathic scoliosis: a case-controlled study.

Background: To date, there are limited studies evaluating abdominal muscle symmetry in adolescent idiopathic scoliosis (AIS) patients and these studies in the literature do not evaluate the rectus abdominis (RA) muscle in AIS patients.

Aim: To evaluate the symmetry of the thickness of the abdominal muscles while standing and supine position in AIS patients.

Design: A case control study.
