Abstract
Methods A 3D Orthoscreen system, designed for postural deformity telediagnostics, using the structural light method, was used for school screening [2,3]. Clouds of dots were acquired for every subject. POTSI, DAPI, kyphosis and lordosis were measured, after marker-less landmarking of anatomical back structures, manually and automatically, for the same subjects. 50 subjects were assessed, 22 male adolescent subjects (average age 15.18 years from 14 to 17) and 28 females (average age 14.55 from 14 to 16) were examined. Their clouds of dots were acquired and saved. Clouds were retrieved and analyzed utilizing 3D Orthoscreen system. An operator (trained professional) retrieved 3D data and analyzed by pointing landmarks manually or automatically. After landmarking, procedure Indices and angular measurements were calculated by the system. MedCalc statistical software (Version 12.1.4.0) was used to calculate Inter-rater correlation for measurements.
Highlights
Posterior Trunk Symmetry (POTSI) and Deformity in the Axial Plane (DAPI) Indices, and sagittal plane curvature measurements, are frequently used to measure deformities
Almost perfect, agreement was found for sagittal plane curvature measurements
Strong, and almost perfect, agreement we found for sagittal plane curvature measurements may coincide with the method of measurement (Debrunner like method)
Summary
The aim of this study was to perform a preliminary assessment, and a reliability test, of the algorithm designed to provide a more reliable way of localizing anatomical back shape landmarks for school screening subjects
