I’m not sure if this pose is made for scoliosis, but it flexes and stretches your back. Maybe it’ll be of a little help to you. You kneel on all fours, arch your back downward (your stomach should curve towards the ground) while your head stretches to the sky and elongates upward. Breath in for the “cow”, and breathing out, arch your back upwards while dropping your head to the floor. Do the second part, the “cat”, while breathing out. Be careful not to take this to extremes, and consult someone before you try this out just in case it hurts your back and causes something worse. Good luck!
