The stepping test: A step back in history
Nervous System Diseases
The stepping test is a valuable part of the neurological examination that is used to localize labyrinthine pathology. The test is known by two eponyms: the "Fukuda Test" in the United States and Asia and the "Unterberger Test" in Europe. Some controversy exists as to which name is correct. Siegfried Unterberger was an Austrian otolaryngologist who initially described the test in 1939. It was modified in 1959 by Tadashi Fukuda, a Japanese otolaryngologist, who introduced a method to better quantify the test results. Thus, the test should be called the "Unterberger Test," unless Fukuda's methods for measurement are used.
