OTHER QUOTES FROM THE PAPER:
The incidence rate of changing pattern was noted 46.1%. The possible reason for these changing patterns could be better explained by the tuning/ balancing mechanism of paraspinal muscles which try to balance the spine, and result into spontaneous regression or stabilization of curve.
The other theory proposed for progression of scoliosis is paraspinal muscle imbalance by several authors. Ford et
al [17] suggested that underlying cause of the adolescent idiopathic scoliosis might be the imbalance in the deep
muscles at the apex of the curve. They supported the hypothesis of Fidler and Jowett [35] who suggested that
increased tonic activity of the deep medial paraspinal muscles, such as multifidus, on one side of the spine
and a consequent effect on vertebral growth could be of importance in the aetiology of idiopathic scoliosis.
We did not find any relationship between side of curve or number of curve and regression, stabilization or progression of curve; however,
boys had higher chances of regression than girls. Additionally, our results proved that there should be possibly other factors responsible, especially in skeletally immature children that might have impact on fate of curve.
Since muscles cause movements and maintain tonus, they can be considered to produce skeletal deformities in situations of imbalance [37]. In other words, situations of imbalance of the back muscles may be the only causal factor for scoliosis.
While Weiss showed decrease in muscular imbalance between convex and concave side with physical rehabilitation program that ultimately reduced the Cobb angle in their subjects [23].
