Literature described Hueter-Volkmann theory regarding disc and vertebral wedging and muscular imbalance for the progression of adolescent idiopathic scoliosis. However many authors reported spontaneous resolution of curves also without any reason for that and the rate of resolution reported is almost 25 . Purpose of this study was to question the role of paraspinal muscle tuning balancing mechanism especially in patients with idiopathic scoliosis with early mild curve for spontaneous regression or progression as well as changing pattern of curves. Methods An observational study of serial radiograms in 169 idiopathic scoliosis children with minimum follow-up one year was carried. All children with Cobb angle 25 and who were diagnosed for the first time were selected. As a sign of immaturity at the time of diagnosis all children had Risser sign 0. No treatment was given to entire study group. Children were divided in three groups at final follow-up Group A B and C as children with regression no change and progression of their curves respectively. Additionally changes in the pattern of curve were also noted. Results Average age was years at first visit and years at final follow-up with an average follow-up of 21 months. 55 169 70 169 and 26 44 169 children exhibited regression no change and progression in their curves respectively. of children 78 169 showed changing pattern of their curves during the
