Body Level/Scoliosis meter for adolescent idiopathic scoliosis postural assessment in three anatomical planes.METHODS This is an observational reliability and concurrent validity study of adolescent referrals to the Orthopaedic department for scoliosis screening at KarolinskaUniversity Hospital, Stockholm, Sweden between MarchMay 2012. A total of 31 adolescents with idiopathic scoliosis(13.6 ± 0.6 years old) of mild-moderate curvatures(25°± 12°) were consecutively recruited. Measurement of cervical, thoracic and lumbar curvatures, pelvic and shoulder tilt, and axial thoracic rotation(ATR) were performed by two trained physiotherapists in one day. The intraclass correlation coefficient(ICC) was used to determine the inter-examiner reliability(ICC2,1) and the intra-rater reliability(ICC3,3) of the Baseline~? Body Level/Scoliosis meter. Spearman's correlation analyses were used to estimate concurrent validity between the Baseline~? Body Level/Scoliosis meter and Gold Standard Cobb angles from radiographs and the Orthopaedic Systems Inc. Scoliometer.RESULTS There was excellent reliability between examiners for thoracic kyphosis(ICC2,1 = 0.94), ATR(ICC2,1 = 0.92) and lumbar lordosis(ICC2,1 = 0.79). There was adequate reliability between examiners for cervical lordosis(ICC2,1 = 0.51), however poor reliability for pelvic and shoulder tilt. Both devices were reproducible in the measurement of ATR when repeated by one examiner(ICC3,3 0.98-1.00). The device had a good correlation with the Scoliometer(rho = 0.78). When compared with Cobb angle from radiographs, there was a moderate correlation for ATR(rho = 0.627).CONCLUSION The Baseline~? Body Level/Scoliosis meter provides reliable transverse and sagittal cervical, thoracic and lumbar measurements and valid transverse plan measurements of mild-moderate scoliosis deformity.展开更多

Awareness of valid and reliable patient history taking,physical examination and clinical testing is important for diagnostic accuracy. Stratified care which targets treatment to patient subgroups based on key characteristics is reliant upon accurate diagnostics. Models of stratified care that can potentially improve treatment effects include prognostic risk profiling for persistent LBP, likely response to specific treatment based on clinical prediction models or suspected underlying causal mechanisms. The focus of this editorial is to highlight current research status and future directions for LBP diagnostics and stratified care.展开更多
