Purpose: To determine if applying direct compression to brachial plexus causes radiating symptoms, suggesting mechanically elicitable cervical spine lesions.
Patient position: Sitting upright or lying supine.
Examiner position: Standing behind while the patient is sitting; Standing on the head side while the patient is lying supine.
Procedure: Apply compression directly on the brachial plexus using the fingers or thumb.
Outcome: The test is positive if pain or other neural symptoms radiate into the upper extremity ipsilaterally. The test is negative if there are no radiating symptoms.
