After Hans Heinrich George Queckenstedt (1876-1918), German physician.]Test to determine whether there is a blockage in the spinal canal or whether cerebrospinal fluid can flow freely.A part of the routine lumbar puncture procedure. It is used to determine whether or not the flow of cerebrospinal fluid is blocked in the spinal canal.A method formerly used to test for spinal narrowing. A lumbar puncture is performed and the pressure of the cerebrospinal fluid measured. An assistant presses on the patient's jugular veins in the neck; this should cause the pressure to rise rapidly, except in the case of spinal stenosis. The test is now superseded by MRI scanning.
