A test done during a lumbar pincture in which pressure is applied to the jugular veins to see if the cerebrospinal fluid is flowing correctly [Described 1916. 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 The test is now superseded by MRI scanning.
