Cobb angle changes after standardized chiropractic intervention in 12 females with adolescent idiopathic scoliosis with double major curve types: a retrospective review of patient records

Background Scoliosis is a 3-dimensional spinal deformity measured in two dimensions. [1] and is the leading orthopedic problem seen in school-aged children, affecting approximately 2-4% of children 10 to 16 years of age. First introduced in 1948, the Cobb angle is the current standard for measuring the severity of scoliosis. As stated by Gstoettner et al. in 2007, “It is an objective measure and is generally used to make decisions about the progression of a curve, as well as the need and success of treatment. Measurements of the Cobb angle bare an intraand interobserver variability of approximately 4° to 8°. The definition of end vertebrae introduces the main source of error.”[2]
