Hi Physiotooting
I have a couple of articles for you. One I will email you for your personal use as it has restricted copyright. One is a evidence-based guideline our management of idiopathicscoliosis and one is a recent systematic review. Both are quite positive about specific exercise
While this evidence won't give you the details of exercise you may want to have, it will help you tease out what works and point you in the right direction of exactly what has been found to be effective - I suggest you then go an look up what the researchers did in the relevant studies.
