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

چکیده
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 surface topography parameters in healthy teenagers.

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...
متن کاملTest-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...
متن کاملAsymmetry Assessment Using Surface Topography in Healthy Adolescents
The ability to assess geometric asymmetry in the torsos of individuals is important for detecting Adolescent Idiopathic Scoliosis (AIS). A markerless technique using Surface Topography (ST) has been introduced as a non-invasive alternative to standard diagnostic radiographs. The technique has been used to identify asymmetry patterns associated with AIS. However, the presence and nature of asymm...
متن کاملThe effect of massage on body mass index and head circumference of healthy neonates
Background: Several methods have been proposed to improve growth in neonates, including touch and massage therapy, however, there are conflicting results about the effect of massage. Therefore, this study was conducted with the aim of determining the effect of massage therapy on body mass and head circumference indicators of healthy infants and also according to gender. Methods: In this random...
متن کاملMultimodal image registration of the scoliotic torso for surgical planning
BACKGROUND This paper presents a method that registers MRIs acquired in prone position, with surface topography (TP) and X-ray reconstructions acquired in standing position, in order to obtain a 3D representation of a human torso incorporating the external surface, bone structures, and soft tissues. METHODS TP and X-ray data are registered using landmarks. Bone structures are used to register...
