Fig. 55.

The Schroth “Side-lying” exercise for major lumbar curves (top) and major thoracic curves (bottom). During this exercise, the patient lies on the lumbar convex side. Light blue arrows represent trunk elongation with cranial and caudal forces. Green half-moons represent areas of expansion of the concavities. Red arrows represent areas of muscle activation, approximating the convexities towards midline, and the direction of the correction to correct the convexities. The dark blue arrow pointing upwards from the right elbow represents the shoulder traction
