Adolescent idiopathic scoliosis (AIS) is treated with various forms of conservative care or surgery, depending on the degree of severity. When AIS is detected early, it can be monitored and initially treated with reduced invasiveness to prevent further progression. AIS manifests itself through deformations of the trunk, which are mostly identified as asymmetries in manual clinical examination. Torsobarography is a new pressure-based surface topographic system for posture analysis and evaluates such associated morphologic asymmetries. The aim of this study is to investigate the diagnostic validity of torsobarography by examining correlation of extracted torsobarographic indices with the Cobb angle and its ability to differentiate between different severities of scoliosis: no scoliosis, mild scoliosis, and moderate scoliosis. A total of 87 subjects (51 females and 36 males) were examined with torsobarography. Six torsobarographic indices were calculated for all subjects: torsobarography angle (TBA), sagittal imbalance index (SII), torso asymmetry index (TAI), shoulder asymmetry angle (SAA), waist asymmetry angle (WAA), and pelvis asymmetry Angle (PAA). These indices were correlated with the Cobb angle, and the differences between severities were statistically analyzed. Three out of six indices (TBA, TAI, and WAA) were able to significantly distinguish between mild and moderate scoliosis. Additionally, those indices showed moderate correlation (ρ = 0.37-0.50) with the Cobb angle measurements. The WAA was the only statistically significant index capable of differentiating between no scoliosis and moderate scoliosis. This study is the first to demonstrate that torsobarography can distinguish between different severities of scoliosis and thus identify a scoliotic deformity that requires bracing over monitoring.
青少年特发性脊柱侧凸（AIS）根据严重程度采用各种形式的保守治疗或手术。当早期发现AIS时，可以对其进行监测，并首先采用侵入性较小的治疗方法以防止病情进一步发展。AIS通过躯干变形表现出来，这些变形在手动临床检查中大多表现为不对称。胸廓压力图是一种用于姿势分析的新型基于压力的表面地形系统，可评估此类相关的形态不对称。本研究的目的是通过检查提取的胸廓压力图指标与Cobb角的相关性及其区分不同严重程度脊柱侧凸（无脊柱侧凸、轻度脊柱侧凸和中度脊柱侧凸）的能力，来研究胸廓压力图的诊断有效性。共有87名受试者（51名女性和36名男性）接受了胸廓压力图检查。为所有受试者计算了六个胸廓压力图指标：胸廓压力图角度（TBA）、矢状面失衡指数（SII）、躯干不对称指数（TAI）、肩部不对称角度（SAA）、腰部不对称角度（WAA）和骨盆不对称角度（PAA）。将这些指标与Cobb角进行相关性分析，并对不同严重程度之间的差异进行统计学分析。六个指标中的三个（TBA、TAI和WAA）能够显著区分轻度和中度脊柱侧凸。此外，这些指标与Cobb角测量值显示出中等相关性（ρ = 0.37 - 0.50）。WAA是唯一能够在无脊柱侧凸和中度脊柱侧凸之间进行区分的具有统计学意义的指标。本研究首次表明胸廓压力图可以区分不同严重程度的脊柱侧凸，从而识别出需要支具治疗而非监测的脊柱侧凸畸形。
