Abstract：
UNASSIGNED: (1) Compare the cross-sectional thickness (CST) and shear wave speed (SWS) of paraspinal muscles (PSM) in adolescent idiopathic scoliosis (AIS) with and without curve progression; (2) investigate the relationship between CST/SWS and radiographic characteristics in AIS with curve progression; (3) compare the CST/SWS between AIS and non-scoliosis controls.
UNASSIGNED: This cross-sectional study analyzed the CST and SWS of PSM in 48 AIS with mild to moderate curvature and 24 non-scoliosis participants. Participants with scoliosis greater than 45° of Cobb angles were excluded. The Change of Cobb angles within the last 6-months was retrieved to allocate AIS into progression and non-progression groups. The SWS and CST of multifidus; longissimus and iliocostalis of the major curve were measured using B-mode ultrasound image with an elastography mode. Discrepancies of the SWS (SWS-ratio: SWS on the convex side divided by SWS on the concave side) and CST (CST-ratio: CST on the convex side divided by CST on the concave side) at the upper/lower end and apical vertebrae were studied.
UNASSIGNED: A higher SWS at the apical vertebrae on the concave side of the major curve (multifidus: 3.9 ± 1.0 m/s vs. 3.1 ± 0.6 m/s; p < 0.01, longissimus: 3.3 ± 1.0 m/s vs. 3.0 ± 0.9 m/s; p < 0.01, iliocostalis: 2.8 ± 1.0 m/s vs. 2.5 ± 0.8 m/s; p < 0.01) was observed in AIS with curve progression. A lower SWS-ratio at apical vertebrae was detected with a greater vertebral rotation in participants with curve progression (multifidus [grade II]: 0.7 ± 0.1 vs. grade I: 0.9 ± 0.2; p = 0.03, longissimus [grade II]: 0.8 ± 0.2 vs. grade I: 1.1 ± 0.2; p < 0.01). CST was not different among the progressive, non-progressive AIS and non-scoliosis controls.
UNASSIGNED: Increased SWS of PSM without change of CST was observed on the concave side of the major curve in participants with progressive AIS.

摘要：
■（1）比较有和没有曲线进展的青少年特发性脊柱侧凸（AIS）的椎旁肌（PSM）的横截面厚度（CST）和剪切波速度（SWS）；（2）研究CST/SWS与AIS中影像学特征之间的关系以及进展曲线；（3）比较AIS与非脊柱侧凸对照之间的CST/SWS。
■这项横断面研究分析了48名具有轻度至中度曲率的AIS和24名非脊柱侧凸参与者中PSM的CST和SWS。排除脊柱侧凸大于45°Cobb角的参与者。检索最近6个月内Cobb角的变化以将AIS分配到进展组和非进展组。多裂的SWS和CST；使用具有弹性成像模式的B模式超声图像测量主要曲线的最长肌和liocostalis。SWS（SWS比率：凸侧的SWS除以凹侧的SWS）和CST（CST比率：凸侧的CST除以凹侧的CST）的差异研究了顶端和顶端椎骨。
■在主曲线凹侧的根尖椎骨处出现较高的SWS（多裂：3.9±1.0m/s与3.1±0.6m/s；p<0.01，长肌：3.3±1.0m/svs.3.0±0.9m/s；p<0.01，髂骨：2.8±1.0m/svs.在具有曲线进展的AIS中观察到2.5±0.8m/s；p<0.01）。在曲线进展的参与者中，发现根尖椎骨的SWS比率较低，椎骨旋转较大（多裂[II级]：0.7±0.1vs.I级：0.9±0.2；p=0.03，长肌[II级]：0.8±0.2vs.一级：1.1±0.2；p<0.01)。CST在进步派中没有什么不同，非进行性AIS和非脊柱侧凸对照。
■在进行性AIS的参与者的主要曲线的凹侧观察到PSM的SWS增加而没有CST的变化。
