Unterberger

Unterberger's test, also known as Unterberger's stepping test or Fukuda stepping test, is a clinical test used in neurology to detect a vestibular system dysfunction. The test was first described by the Austrian neurologist Franz Unterberger in 1938.

Procedure

The Unterberger's test is performed by asking the patient to march in place with their eyes closed for about 30 seconds. A positive test is indicated by the patient rotating to one side, which suggests a lesion in the vestibular apparatus on the opposite side.

Clinical significance

Unterberger's test is used to assess the function of the vestibular system, which is responsible for maintaining balance and spatial orientation. It can help in diagnosing conditions such as vestibular neuritis, labyrinthitis, and Meniere's disease. However, it is not a definitive test and should be used in conjunction with other clinical assessments.

Limitations

The test has some limitations. It is not specific for vestibular disorders and can be influenced by other factors such as proprioception and vision. It also has a high false-positive rate, meaning that it can indicate a problem when there isn't one.
