The Bárány Society position on 'Cervical Dizziness'

Area of Science:

• Neurology
• Otolaryngology
• Vestibular Science

Background:

• Cervical Dizziness, or Cervical Vertigo, is a debated condition.
• The Bárány Society Classification OverSight Committee (COSC) reviewed existing literature.
• Expert consensus is crucial for defining such conditions.

Purpose of the Study:

• To evaluate the evidence supporting a link between neck pathology and vertigo.
• To clarify the relationship between neck pain and vestibular symptoms.
• To guide future research on Cervical Dizziness.

Main Methods:

• Expert review of published literature.
• Analysis of proposed mechanistic links between cervical structures and vertigo.
• Consideration of confounding factors in research design.

Main Results:

• Limited evidence supports a direct mechanistic link between neck pathology and vertigo.
• Migraine, including vestibular migraine, is the most frequent cause of co-occurring neck pain and vestibular symptoms.
• Head movements aggravate most vestibular conditions, potentially linking neck muscle tension to reduced mobility.

Conclusions:

• The Bárány Society COSC currently finds insufficient evidence to establish Cervical Dizziness as a distinct entity.
• Further high-quality, placebo-controlled research is required to explore potential links, particularly regarding neck proprioception.
• Preliminary diagnostic criteria for clinical use are not yet proposed, pending further evidence.
