A positive Spurling's sign is when the pain arising in the neck radiates in the direction of the corresponding dermatome ipsilaterally.
Patients with a positive Spurling's sign can present with a variety of symptoms, including pain, numbness and weakness.
The results of this test can guide a clinician when considering further imaging and necessary steps needed to make a proper diagnosis.
The study results showed the Spurling test was 30% sensitive, and 93% specific for finding cervical radiculopathy diagnosed by electrodiagnostic examination.
The conclusions drawn from this study demonstrate clinical utility of the Spurling test to confirm cervical radiculopathy rather than for screening purposes.
