Queckenstedt's maneuver
Queckenstedt's maneuver is an outdated clinical test, formerly used for diagnosing spinal stenosis. The test is performed by placing the patient in the lateral decubitus position, thereafter the clinician performs a lumbar puncture. The opening pressure is measured. Then, the clinician's assistant compresses both jugular veins, which leads to a rise in the intracranial pressure. Given normal anatomy, the intracranial pressure will be reflected as a rapidly rising pressure measured from the lumbar needle, within 10-12 seconds. If there is a stenosis in the spine, there will be a damped, delayed response in the lumbar pressure, thus a positive Queckenstedt's maneuver. Nowadays this test has been made mostly superfluous by superior imaging modalities like MRI and CAT.[1]
The test is named after Hans Heinrich Georg Queckenstedt who described it in 1916.[2]
