Cervical vertigo diagnosed by posturography? Preliminary report.

Posturographic recording with the patient's head in retroflexion has been proposed as a reliable test for diagnosing cervical vertigo. The clinical experience suggests that a positive result in this test-condition could be accepted as suggestive for cervical involvement, when other data corroborate it, but that it is not per se pathognomonic. In fact, this test is negative in most cases with other cervical indications, whereas it has been found positive, in cases with no cervical indications. A positive test, however, is significantly more frequent in "cervical" cases. On the other hand, otolithic influence upon the test-performance has also to be taken into account.
