To estimate the criterion validity of sagittal thoracolumbar spine measurement using a surface topography method in a clinical population against the gold standard and to estimate concurrent validity against two non-radiographic clinical tools.
In this cross-sectional validity study, thoracolumbar curvature was measured in adults with spinal conditions recruited from a specialist orthopaedic hospital. A surface topography method using a Kinect sensor was compared to three other measurement methods: spinal radiograph (gold standard), flexicurve and digital inclinometer. Correlation coefficients and agreement between the measurement tools were analysed.
Twenty-nine participants (79% female) were included in criterion validity analyses and 38 (76% female) in concurrent validity analyses. The surface topography method was moderately correlated with the radiograph (r = .70, p < .001) in the thoracic spine, yet there was no significant correlation with the radiograph in the lumbar spine (r = .32, p = .89). The surface topography method was highly correlated with the flexicurve (r = .91, p < .001) and digital inclinometer (r = .82, p < .001) in the thoracic spine, and highly correlated with the flexicurve (r = .74, p < .001) and digital inclinometer (r = .74, p < .001) in the lumbar spine.
The surface topography method showed moderate correlation and agreement in thoracic spine with the radiograph (criterion validity) and high correlation with the flexicurve and digital inclinometer (concurrent validity). Compared with other non-radiographic tools, this surface topography method displayed similar criterion validity for kyphosis curvature measurement.
使用表面地形测量法在临床人群中评估矢状位胸腰椎测量的标准效度，并评估与两种非影像学临床工具的同时效度。
在这项横断面有效性研究中，从一家骨科专科医院招募了患有脊柱疾病的成年人，对其胸腰椎曲率进行了测量。使用 Kinect 传感器的表面地形测量法与其他三种测量方法（金标准脊柱 X 光片、Flexicurve 和数字倾角计）进行了比较。分析了测量工具之间的相关系数和一致性。
在标准效度分析中，29 名参与者（79%为女性）被纳入，在同时效度分析中，38 名参与者（76%为女性）被纳入。表面地形测量法与 X 光片在胸椎中度相关（r=0.70，p<0.001），但在腰椎无显著相关性（r=0.32，p=0.89）。表面地形测量法与 Flexicurve（r=0.91，p<0.001）和数字倾角计（r=0.82，p<0.001）在胸椎高度相关，与 Flexicurve（r=0.74，p<0.001）和数字倾角计（r=0.74，p<0.001）在腰椎高度相关。
表面地形测量法在与 X 光片（标准效度）的胸椎具有中度相关性和一致性，与 Flexicurve 和数字倾角计（同时效度）具有高度相关性。与其他非影像学工具相比，这种表面地形测量法在测量后凸曲度方面具有相似的标准效度。
