RT Journal Article T1 Spine curvature analysis between participants with obesity and normal weight participants: a biplanar electromagnetic device measurement A1 González-Sánchez, Manuel A1 Luo, Jin A1 Lee, Raymond A1 Cuesta-Vargas, Antonio K1 Obesidad - Complicaciones K1 Columna vertebral - Anomalías y malformaciones AB To analyse and compare standing thoracolumbar curves in normal weight participants and participants with obesity, using an electromagnetic device, and to analyse the measurement reliability.Material and methods: Cross-sectional study was carried out. 36 individuals were divided into two groups (normal-weight and participants with obesity) according to their waist circumference. The reference points (T1-T8-L1-L5 and both posterior superior iliac spines) were used to perform a description of thoracolumbar curvature in the sagittal and coronal planes. A transformation from the global coordinate system was performed and thoracolumbar curves were adjusted by fifth-order polynomial equations. The tangents of the first and fifth lumbar vertebrae and the first thoracic vertebra were determined from their derivatives. The reliability of the measurement was assessed according to the internal consistency of the measure and the thoracolumbar curvature angles were compared between groups.Results: Cronbach's alpha values ranged between 0.824 (95% CI: 0.776-0.847) and 0.918 (95% CI: 0.903-0.949). In the coronal plane, no significant differences were found between groups; however, in sagittal plane, significant differences were observed for thoracic kyphosis.Conclusion: There were significant differences in thoracic kyphosis in the sagittal plane between two groups of young adults grouped according to their waist circumference.
