Jackson’s compression test

Purpose: To identify the presence of cervical radiculopathy among patients with upper quadrant pain.

Patient Position: Sitting upright.

Examiner Position: Beside or behind the patient.

Procedure: Ask the patient to turn/rotate the head to the unaffected side. Carefully apply axial compression vertically downwards through the head. Repeat the same on the affected side.

Outcome: The test is positive if the patient has radiating pain down the arm on the corresponding dermatome ipsilaterally. The findings should be used to confirm cervical radiculopathy/nerve compression, in conjunction with other neurologic/manual tests.
