Spine deformity during adolescent idiopathic scoliosis can induce a rib-cage deformity. This bone deformity can have direct consequences on the chest-wall muscles, including intercostal muscles, leading to respiratory impairments in individuals with severe cases. The aim of this study was to determine whether shear-wave elastography can be used to measure intercostal-muscle shear-wave speed (SWS) in healthy children and those with adolescent idiopathic scoliosis (AIS). Nineteen healthy participants and 16 with AIS took part. SWS measurements were taken by three operators, twice each. Average SWS was 2.3 ± 0.4 m/s, and inter-operator reproducibility was 0.2 m/s. SWS was significantly higher during apnea than in normal breathing (p < 0.01) in both groups. No significant difference was observed between groups in apnea or in normal breathing. Characterization of the intercostal muscles by ultrasound elastography is therefore feasible and reliable for children and adolescents with and without scoliosis.
脊柱畸形在青少年特发性脊柱侧凸中可引起胸廓畸形。这种骨骼畸形可能直接影响到胸壁肌肉，包括肋间肌，导致严重病例的个体出现呼吸功能障碍。本研究旨在确定剪切波弹性成像是否可用于测量健康儿童和青少年特发性脊柱侧凸（AIS）患者的肋间肌剪切波速度（SWS）。19 名健康参与者和 16 名 AIS 患者参与了研究。由三名操作人员进行 SWS 测量，每人测量两次。平均 SWS 为 2.3±0.4 m/s，操作者间可重复性为 0.2 m/s。两组患者在屏气时的 SWS 均显著高于正常呼吸时（p<0.01）。两组在屏气或正常呼吸时均无显著差异。因此，超声弹性成像可用于对有和无脊柱侧凸的儿童和青少年的肋间肌进行特征描述，且具有可行性和可靠性。
