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 .
Objective parallel-forms reliability assessment of 3 dimension real time body posture screening tests
Background Screening tests play a significant role in rapid and reliable assessment of normal individual development in the entire population of children and adolescents . Body posture screening tests carried out at schools reveal that 50 - 60 % of children and adolescents demonstrate body posture abnormalities , with 10 % of this group at risk for progressive spinal deformities . This necessitates the search for effective and economically feasible forms of screening diagnosis . The aim of this study was to assess the reliability of clinical evaluation of body posture compared to objective assessment with the Zebris CMS-10 system ( Zebris Medical GmbH ) . Methods The study enrolled 13 - 15-year-old pupils attending a junior secondary school ( mean age 14.2 years ) . The study group consisted of 138 participants , including 71 girls and 67 boys , who underwent a clinical evaluation of the body posture and an examination with the Zebris CMS 10 system .  Results Statistically significant discrepancies between the clinical and objective evaluation were noted with regard to lumbar lordosis in boys ( n = 67 ) and thoracic kyphosis in girls ( n = 71 ) . No statistically significant differences in both groups were noted for pelvic rotation and trunk position in the frontal plane . Conclusions 1 . The finding of significant discrepancies between the results of assessment in the sagittal plane obtained in the clinical examination and Zebris CMS-10-based assessment suggests that clinical evaluation should be used to provide a general estimation of accentuation or reduction of spinal curvatures in the sagittal plane.2 . The clinical evaluation of posture is reliable with regard to assessment in the frontal plane.3 . The Zebris CMS-10 system makes the clinical examination significantly more objective with regard to assessment of the physiological curvatures and may be used to make screening tests more objective with regard to detecting postural defects
