Ott sign

The Ott sign or Ott measure is a function test for the mobility of the thoracic spine . On the standing patient, a skin mark is applied over the spinous process of the seventh cervical vertebra (CU 7) and 30 cm further down ( caudal ). The changes in the measuring distance during movements (flexion) are recorded: 3–4 cm are normal. In diseases with stiffening of the spine (e.g. ankylosing spondylitis (Bechterew's disease)), mobility is reduced and the changes are smaller.

The sign was described by Victor Rudolf Ott (1914–1986).
