Fig. 56.

The Schroth prone exercise. The leg of the lumbar convex side (left leg) is abducted and the pelvis is supported and elevated by a footstool. The lower abdomen is supported by a roll, as is the right shoulder, to facilitate trunk stabilization during the exercise. Blue arrows on the shoulders represent bilateral shoulder traction. Turquoise arrows represent trunk elongation with cranial elongation and caudal traction forces. Red arrows represent areas of muscle activation around the convexities towards the midline. Green half-moons represent areas of expansion of the concavities
