It is typically quantified using the standardized Cobb angle method.

The Cobb angle is the preferred method of measuring kyphosis.

Cobb angle is a common measure to classify scoliosis.

For patients with two curves, Cobb angles are followed for both curves.

John Robert Cobb, known for the Cobb angle, also practiced at HSS for some time.

Independently of the Cobb angle, the affected vertebra and the age, idiopathic scoliotic people have a larger rachis flexion range of motion and a narrower hips extension range of motion than non-scoliotic people.

The standard method for assessing the curvature quantitatively is measurement of the Cobb angle, which is the angle between two lines, drawn perpendicular to the upper endplate of the uppermost vertebrae involved and the lower endplate of the lowest vertebrae involved.

To obtain an accurate and consistent assessment of the severity of spinal deformity, so as to avoid unnecessary surgery, Cobb developed the simple and reliable method for measuring the angle of curvature which has now come to be known as the Cobb Angle.
