Measurement and analysis of torsional eye movements are available in the VisualEyes™ software. These measurements provide an assessment of the vertical semicircular canals, otoliths, and their centra…
This video tutorial provides some tips, tricks, suggestions and ideas for how and when to apply masking noise to the bone conduction ABR. You can read the full transcript below. Introduction This vid…

In June 2023, with the support of the William Demant Foundation, Dr. Daniel Romero and audiology students from Vanderbilt University Medical Center (VUMC) embarked on a mission trip to Kraków, Poland…
The idea of a rotational chair was first introduced by Robert Bárány in 1907 and has been used for a variety of different clinical needs since that time. However, newer vestibular tests, such as the…

The ‘wideband’ part of the name Wideband Absorbance (WBA) refers to the stimulus, which is a click i.e. a broadband sound. The ‘absorbance’ part of the name refers to how effectively the energy from…
It is relatively simple to track horizontal and vertical eye movements using videonystagmography (VNG) because they can be directly deduced from the position of the pupil. However, torsional movement…
This video gives an overview of the auditory Middle Latency Response (MLR), including a description of the MLR, the electrode montage and stimuli used, how to prepare the patient, as well as a breakd…
