In this article, we will discuss the Cervical Rotation Lateral Flexion Test. So, let’s get started.
Cervical Rotation Lateral Flexion Test
Aim: To assess the contribution of first rib hypomobility to brachial plexus pain.
Test Position: Sitting.
Procedure: Rotate the head away from the painful side to end range. While maintaining end range rotation, attempt to laterally flex as far as possible on the tested side. If unable to laterally flex the head, the test is considered positive.
Importance: On turning your head away from the affected side, you’ll unable to laterally flex your head to the affected side in case of an elevated/hypomobile first rib. This is due to the first rib blocking the transverse process of C7. It is an important test to see the contributions of first rib hypomobility to pain associated with the neck and upper extremity, such as some cases of Thoracic Outlet Syndrome.
