Abstract
IRON, Paris, FranceE-mail address: cvnechel@ulb.ac.beKeywords: Vertigo; Dizziness; Imbalance; Cervical vertebrae; Cervicalgia‘‘Cervical vertigo’’ is rarely truevertigo but there are several experimental andclinical arguments in favour of a possible origin of cervical postural instability.Acorrectperceptionofthebodybalanceduringheadmovementrequiresbothavestibular signal and precise cervical static and dynamic proprioceptiveinformation. This finding alone is sufficient to validate the concept of a feelingof instability of cervical origin, called by some authors ‘‘cervical vertigo’’. Avascular mechanism is very rarely involved in the presence of two functionalvertebral arteries and a normal Willis polygon. The increase in the gain ofcervical-ocularreflexorthepresenceofacervicalnystagmusarenotconvincingarguments for a cervical origin of dizziness. Diagnostic criteria proposed in theliterature require a temporal relationship between neck pain and posturalinstability even during recurrences, and the lack of neck pain excludes thisdiagnosis. Finally, other causes of dizziness should be eliminated.Further readingBrooks JX, Cullen KE.
