Changes in radiographic parameters. To the left: dark green, significant improvement in Cobb’s angle (curves) and Nash and Moe’s classification (error); light green, insignificant improvement in Nash and Moe’s classification (error) and in rib vertebra angle (line); red, insignificant deterioration in rib vertebra angle (line). To the middle and right: an example of pre- (middle) and post-injection (right) radiographs for patient number 9, where there is a smaller lumbar Cobb’s angle and larger thoracic Cobb’s angle after injection of botulinum toxin A
