[The temporal course of nystagmus reactions after rotational stimulation (modified Veits long rotational method). Part II. Recommendations for the simplification of nystagmus evaluation in the rotational test].
In this study, on the basis of the graphics showing the time course of the nystagmus reactions following rotatory stimuli (Part I), some practical proposals are made on how the nystagmus responses following the rotatory test can be routinely analysed more quickly. The recommendations are oriented to the requirement that the selection of defined 30-second-intervals during the per- and postrotatory phase for the nystagmus analysis should reflect the total reaction in healthy subjects as well as in patients with acute vestibular lesions in a representative manner. It is also shown that reducing the analysis intervals to only 15 seconds or selecting unfavourable segments, can lead to an unacceptable falsification of the results.
