Tests and diagnosis
By Mayo Clinic staffYour doctor will record a history of your condition and conduct a physical exam. The exam may include the following:
- Forward bend test. Your doctor asks you to bend forward from the waist while he or she views the spine from the side. With kyphosis, the rounding of the upper back may become more obvious in this position. In postural kyphosis, the deformity corrects itself when you lie on your back.
- Neurological functions test. Although neurological changes accompanying kyphosis are rare, your doctor may check for them by looking for weakness, changes in sensation or paralysis below the site of the kyphosis.
- Spinal imaging tests. Your doctor may take an X-ray to confirm the kyphosis, determine the degree of curvature and detect any deformity of the vertebrae, which helps identify the type of kyphosis. For example, the appearance of wedge-shaped vertebrae or other features on X-ray differentiates between postural kyphosis and Scheuermann's kyphosis. In older adults, X-rays may show arthritic changes in the spine, which can contribute to an increase in pain. If your doctor suspects a tumor or infection, he or she may request an MRI of your spine.
- Pulmonary function tests. Your doctor may also use breathing tests to assess any breathing difficulty caused by the kyphosis.
