The unclear etiologies for scoliotic and kyphotic deformities of the spine are responsible for uncertainty in treatment options. A constant reference to what normal growth and to what the optimal construction of the entire spine should be at the end of growth is lacking.
Newly developed examination of sitting children with testing of muscular tightness is helpful. This examination highlights the different disturbances of growth that keep the spine from developing optimal configuration and thereby optimal function. Prolonged sitting of children exists only 130 years or less.
