Schober maneuver

Schober maneuver

(shō′bĕr)
A test for flexibility of the lumbar spine, used to determine the presence of ankylosing spondylitis (AS) in patients with low back pain.

Patient care

The patient is asked to stand erect and a mark is placed on the skin overlying the second sacral vertebra. A second mark is placed on the skin 10 cm above the first. The patient then is asked to bend forward. A repeat measurement of the distance between the two marks should equal or exceed 15 cm. If it does not, the patient may have an inflexible or “bamboo” spine, characteristic of AS.
