Abstract: | Purpose] The objective of the study was to evaluate the symmetry of the thickness of the
abdominal muscles at rest and while standing in patients with adolescent idiopathic
scoliosis. Subjects and Methods] An ultrasound assessment was performed of the
side-to-side differences of the external oblique (EO), internal oblique (IO), and
transversus abdominalis (TrA) muscles in the supine and standing positions in adolescent
idiopathic scoliosis (AIS) and control groups. Results] In the AIS group, 64.3% of the
patients had left scoliosis with a mean Cobb angle of 10.7°, and 35.7% of the patients had
right scoliosis with a mean Cobb angle of 10°. In the supine position, the thickness
asymmetry of the TrA was greater in the AIS compared with the control group by an average
of 14% (95% CI 3.9–24.2). Conclusion] Among the abdominal muscles examined, patients with
AIS exhibited more asymmetry only for the TrA. In the standing position, the TrA was as
symmetric in the patients as in the control group. Mild scoliosis has no impact on the
symmetry of the thickness of the OE and OI in the supine and standing positions. The
direction of curvature had no effect on the symmetry of the abdominal muscles studied.Key words: Adolescent, Idiopathic scoliosis |
