How accurate is the Spurling maneuver for detection of cervical radiculopathy?
Metadata[+] Show full item record
The Spurling maneuver has a sensitivity ranging from 26% to 92% and a specificity ranging from 95% to 100%, when computed tomography (CT) myelogram, magnetic resonance imaging (MRI), or surgery are used as reference standards. Consequently, the Spurling maneuver is better for ruling in cervical pathology than ruling it out. (SOR B, based on 4 diagnostic studies with heterogeneous results.)
