Scoliosis is a curvature of the spine. Many people say they have scoliosis when they have a slight curve but scoliosis is usually defined as a lateral or rotational curve over greater than 20 degrees.
Several studies have verified than chiropractors can treat scoliosis effectively with spinal adjustments (manipulation) in conjunction with soft tissue work and exercise.
Most of the studies show a 3 to 15 degree reduction in spinal curves following treatment that lasts between a few weeks to 24 months. 66% of the patients had some reduced pain, increased mobility and or reduction in the curve. All the usual medical treatments do not reduce the curvature except for surgery which has other risks and limitations.
