Effect of dynamic thoracolumbar orthosis on Scheuermann's kyphosis angle

this study was aimed at assessing the effect of a new thoracolumbar orthosis on patients with Scheuermann's kyphosis referred to Iran medical university of Tehran in collaboration with a clinic of technical ortopedea in Isfahan. This new version of orthosis had a dynamic system as compared to previous ones which enabled the spine to extend. a questionnaire along with a radiographic picture of spine were used for evaluating the efficacy of this kind of orthosis. Measurement of the Cobb angles was also performed in 3 stages. mean difference correction of Cobb angle for dynamic thoracolumbar orthosis was 29.5% and mean difference correction of Cobb angle for Milwaukee was 35.5%. Difference of Cobb angle was measured by Cobb angle before application orthosis and by second month of its usage. results showed that not only was the new dynamic thoracolumbar orthosis effective in orthosis correction and improved Cobb angle at 2 months follow-up but also it was well accepted by the user thanks to its beautiful structure.
