They understood the changes in function as well as the altered contour of the back. Structural weakness frequently has been found associated with functional changes in scoliosis.2 Curvatures have been found to arise as the result of inadequate functional capacity of the structures. This functional insufficiency is sometimes referred to as a decompensation.3 The primary rôle in the development of a decompensation of adolescent scoliosis is played by
