Abstract	Idiopathic scoliosis (IS) is characterized by three-dimensional (3D) deformity of the spine and rib cage which can increase during growth. The morphologic changes of the trunk result in posture asymmetries. Correction of posture is an important goal of physiotherapy interventions among persons with IS to prevent scoliosis progression, to reduce morphologic deformities and their impact on quality of life. Currently, there are no tools that globally quantify changes in posture that may be attributable to scoliosis progression or to treatment effectiveness, that are usable in a clinical setting. The objective of this thesis was thus to develop and validate a new clinical quantitative posture assessment tool among persons with IS. More specifically, this project aims to determine reliability and concurrent validity of posture indices (PI) of this new tool and to verify their capacity to detect changes between standing and sitting positions. We conducted a literature review and selected 34 PI representing frontal and sagittal alignment of the different body segments. We constructed a software-based quantitative posture assessment tool to calculate different PI (angular and linear measurements). The software has a user-friendly graphical interface and allows calculation of PI from a set of markers selected interactively on digital photographs. For the reliability and validity studies, standing posture of 70 participants aged 10 to 20 years old with IS (Cobb angle: 15o to 60o) was assessed on two occasions by two physiotherapists. Markers placed on several bony landmarks as well as natural reference points (eyes, ear lobe, etc.) were used to measure the PI from photographs with the 2D tool and to calculate 3D PI obtained from trunk reconstructions with a surface topography system. Frontal and sagittal Cobb angles and trunk list were also calculated on radiographs. The generalizability theory was used to estimate the reliability and standard error of measurement (SEM) of PI of the 2D tool. Pearson correlation coefficients served to estimate concurrent validity of the 2D trunk PI with corresponding 3D PI and with those obtained from radiographs. Fifty participants were assessed for the comparative study
