A good physical therapist and/or good chiropractor will be your best aid. There are 2 types of scoliosis: structural and functional. Structural is the one that you can not change. However, functional you can, but it’s not simple. Luckily, this is the most common type of scoliosis as well. The key is to relax the tight muscles on the concave side. You can do this manually via massage techniques and through stretching. Then you want to focus on core stabilizing exercises (i.e. planks, balance exercises). If you do these exercises after you inhibit the tight muscles then the muscles on the convex side will have the opportunity to fire as much or more than the muscles on the concave side.
