Cervical rotation lateral flexion test


Purpose[edit | edit source]

The purpose is to test for the presence of 1st rib hypomobility in patients with brachialgia with or without radicular pain as well as thoracic outlet syndrome. [1][2]

Technique[edit | edit source]

  • The test is performed with the patient in a sitting.
  • The cervical spine is passively and maximally rotated away from the side being tested.
  • While maintaining this position, the spine is gently flexed as far as possible moving the ear toward the chest.
  • A test is considered positive when the lateral flexion movement is blocked.

The reference standard is the presence of rib hypomobility on cineradiography in subjects with brachialgia.


Cervical rotation
Lateral flexion of the cervical spine toward the chest

Evidence[edit | edit source]

Diagnostic accuracy and reliability are concluded as 0.84 and 1.0 Kappa values respectively in a study. [3]

Although it is frequently used to decide whether to perform a thrust manipulation targeting the first rib, it does not help predict who will benefit from upper rib manipulation. [4]
