iPhone measurements correlated well with scoliometer measurements .
2D photography results had a moderate to high correlation with 3D topography results .
Conclusions Overall , strong levels of evidence exist for iPhone and scoliometer measurements , with a high to very high reliability and moderate to very high validity .
Limited evidence exists for aesthetic tools TRACE and AI and 2D photography .
These results indicate there are accurate and reproducible anthropometric measures that are inexpensive and applicable in therapy setting s to assess postural asymmetry ; however , these only exist for measurement in the transverse plane , despite 3D characteristics of AIS .
Abstract Purpose As accurate and reproducible measurements of spinal curvature are crucial in the examination of patients with adolescent idiopathic scoliosis ( AIS ) , this systematic review aims to report on the reliability and validity of a range of inexpensive and easily administered anthropometric methods of postural asymmetry measurement in an AIS population , to inform practice in a clinical setting .
Prediction of Cobb Angle in Idiopathic Adolescent Scoliosis
We did a prospect i ve study of 291 children and adolescents with idiopathic scoliosis to identify possible correlations between clinical ( scoliometer value , age , height ) and radiographic ( Cobb angle , Nash-Moe rotation , Risser iliac apophysis classification ) parameters to predict the curve angle . There was a statistically significant correlation between thoracic , thoracolumbar , and lumbar scoliometer values and the thoracic , thoracolumbar , and lumbar Cobb angles , respectively ( Pearson ’s r-0.685 , 0.572 , and 0.677 , respectively ) . There was a statistically significant correlation between Cobb angle in the thoracic , thoracolumbar , and lumbar spine and the patients ’ age and height . Mathematical formulas that predict the Cobb angle of thoracic , thoracolumbar , and lumbar scoliosis using the scoliometer measurements are reported
