Table 2 The mean and standard deviation (mean ± SD) of the difference in Cobb angles is shown separately for the two groups for various curves in two planes for comparison at the start of treatment with and without brace T0 OB-IB and after one year of brace treatment and the progression (Prog) rate after one year(T0 OB -T1)

From: A new brace treatment similar for adolescent scoliosis and kyphosis based on restoration of thoracolumbar lordosis. Radiological and subjective clinical results after at least one year of treatment
