Background: Patients with idiopathic scoliosis are exposed to approximately 25 radiographic examinations of their spine throughout the clinical follow-up using the Cobb angle. Several non-invasive and radiation-free methods have been proposed to measure scoliotic deformities, including the scoliometer.
Objectives: To measure the intra- and interrater reliability of the scoliometer measurements, to assess the correlation of the values obtained by the scoliometer measurements with the Cobb angles obtained by radiography, and to assess the sensitivity and specificity of the scoliometer measurements for the different diagnostic criteria for the referral of idiopathic scoliosis.
Background: Although photogrammetry is a widespread technique in the health field, despite of the methodological efforts distortions in the angular readings of the images are common.
Objective: To measure the error of angular measurements in photo images with different digital resolutions in an object with pre-determined angles.
Methods: We used a rubber ball with 52 cm in circumference.
Background: the scoliometer was developed to analyze the axial rotation of the trunk in patients with idiopathic scoliosis. However, there is controversy regarding the reliability of the measures obtained with this device.
Objectives: to test the intra-rater and inter-rater reliability of the scoliometer in patients with scoliosis.
Background: An important parameter in cross-cultural adaptations, and concurrent validity are the relationships between the performance of an instrument of interest and the performance of a similar instrument with known validity.
Objective: To determine the concurrent validity of the Brazilian version of the revised questionnaire of the Scoliosis Research Society (Br-SRS-22r) and the Brazilian version of the Short-Form-36 questionnaire (SF-36).
Methods: Fifty-four patients with idiopathic scoliosis were selected.
