Test-retest standard error of measurements for full-torso surface topography parameters in healthy teenagers

Test-retest standard error of measurements for full-torso surface topography parameters in healthy teenagers

Methods Twenty-two healthy volunteers between 10-17 years old, with a body mass index of 19.1 ± 3.3 kg/m2, scoliometer measure of 3.6° ± 2.5°, and without pain were included. Four Minolta 910 Laser Scanners and a standard positioning frame were used to record ST scans. One evaluator positioned all subjects, marked 11 reference points, and scanned. Immediately after, reference points were erased...

Test-retest standard error of measurements for full-torso surface topography parameters obtained with the arms at 30 and 90 degrees of elevation in healthy teenagers

Introduction The objective of this study was to report full-torso surface topography (ST) parameters and to determine test-retest standard error of measurement (SEM) in adolescents without spinal deformities. ST is used to quantify the external deformity of the torso due to scoliosis. A normative ST database is being developed to help interpret the ST parameters used to describe scoliosis. Test...

Differences in measures of full-torso surface topography among healthy teenagers are independent of growth indicators

Introduction Surface topography (ST) has been proposed to monitor changes in spinal and rib cage deformity in adolescent with idiopathic scoliosis. The changes in ST parameters used to monitor scoliosis should be related to scoliosis progression and not to changes in torso shape occurring with growth. The objective was to determine the correlation between growth indicators and full-torso surfac...

Test-retest validity of acoustic pharyngometry measurements.

BACKGROUND Acoustic reflectometry is a relatively new technique that quantifies upper airway obstruction. The oropharyngeal airway is geometrically complex and variable; therefore establishing a standard operating protocol and understanding the possible sources of artifacts are of great importance in obtaining reliable results. This work aims at assessing the repeatability of pharyngeal cross-s...
