Queckenstedt's test

 [kwek´en-stets″]
when the veins in the neck are compressed on one or both sides there is a rapid rise in the pressure of the cerebrospinal fluid of healthy persons, and this rise quickly disappears when pressure is taken off the neck. But when there is a block in the spinal canal the pressure of the cerebrospinal fluid is affected little or not at all by the maneuver.

Queckenstedt's test

A test used to detect a block in the circulation of CEREBROSPINAL FLUID in the spinal canal. While performing a LUMBAR PUNCTURE and measuring the pressure in the CSF, one of the jugular veins is briefly compressed. The pressure in the CSF should rise if there is no obstruction. (Hans Heinrich Georg Queckenstedt, 1876–1918, German physician).
