The period saw the establishment, for instance, of procedures such as pneumoventriculography (1918) or pneumoencephalography (1919), myelography with iodine oil (1922), cerebral angiography (1927) and electroencephalography (1929) . Prior to this, in 1916, and thus exactly 100 years ago, Hans Queckenstedt (1876–1918) had described the obstruction test which would later be named after him. With the help of this examination method, it was henceforth possible to detect spinal cord compression lesions based on changes in cerebrospinal fluid (CSF) pressure.
The procedure involves a hand being placed flat on the neck, bringing about a temporary compression of the jugular veins. The resulting venous congestion leads to an increase in intracranial CSF pressure, which transfers to the spinal canal. A positive Queckenstedt test means that...
