However, this information is about abnormal kyphosis, which is spinal curvature causing a hunchback or slouching posture. This spinal disorder generally affects the thoracic spine and sometimes the cervical spine. Kyphosis can cause back pain, muscle fatigue, and stiffness on the mild side of the spectrum. In severe cases, it can cause chest pain and make breathing difficult.
A spine affected by kyphosis, however, shows evidence of a forward curvature of the back bones (vertebrae) in the upper back area, giving a humpback appearance. The Scoliosis Research Society defines kyphosis as a curvature of the spine measuring 45 degrees or greater on an x-ray.
