Yes, there’s some truth to that, but I wouldn’t think of it as simply “convex = stretch” and “concave = strengthen.” With scoliosis, tight doesn’t necessarily mean strong, and stretched doesn’t necessarily mean weak. A muscle can feel very tight because it’s actually overworking and compensating, while still not being strong or efficient. Generally, we want to create more space and mobility where the body is compressed, improve the rotation and alignment of the rib cage/spine, and then strengthen both sides in that more balanced position. The exact focus really depends on your individual curve and compensations. Hope that helps Christine!
