Ooo...ask me...ask me


scoliosis and riding is a bit of a pet subject of mine at the moment.
Ditto everything LMS said
Generally, if you were riding at the time that you discovered your curvature, then riding is unlikely to straighten your back. However, using riding to keep the back muscles stronger can help to slow the progression of the curve.
Riding should help to increase and maintain the flexibility of your back, meaning that any procedures undertaken later would have a greater chance of significantly reducing your curve.
If you get sore muscles due to the uneven strain on the different sides of your back, riding can help normalise the muscle tone and so relieve back pain.
And general points (shouldn't be relevant to you, but may be to others reading)
If you have had surgery and have lots of the vertebrae fused (particularly if they are in the lumbar region) then you should only ride in walk...especially if you also have instrumentation. This is due to both the reduced flexibility of your spine making it harder to absorb any upwards movement, and the fact that a fall could damage your back or instrumentation.
If someone has significant rotation as well as lateral curvature it could affect their pulmonary system, and so would be less able to cope with cardiovascular exertion.
Infantile scoliosis is fairly likely to correct naturally. However, if you teach someone with juvenile or adolescent scoliosis then you need to be careful because the curves can advance fast during growing periods...they may need their riding assessed at regular intervals to make sure that the right things are being done.
I'll shut up now

could go on for a looooong time about this
