Occupational vestibular disorders carry a high medico legal and economic burden. The occupational medicine physician must rely on rapid, non-invasive, economical and reproducible screening tests. This article compares the simplified caloric test of Veits (CTV) with the skull vibration-induced nystagmus test (SVINT) in 87 workers. The end points were reproducibility, tolerance and duration of the examination. The mean duration of the CTV was 15 minutes whereas that of SVINT was one minute. In 69 subjects there were autonomic side-effects to CTV whereas SVINT was much better tolerated. The authors conclude that the SVINT should be included in the screening of subjects during occupational medical check-ups. It is a rapid, robust and reliable test as it is not influenced by compensation.
