Dependent head posture dizziness syndrome: a case report

Abstract

Dizziness is a symptom frequently encountered in clinical settings and requires a comprehensive differential screening process. The dizziness types commonly referred to rehabilitation are peripheral and central vestibular disorders, vestibular hypofunction, and cervicogenic dizziness. While cervicogenic dizziness continues to present as a diagnosis of exclusion, there is some agreement that cervical mobility is important to maintain vestibular integrity. This case report highlights the importance of cervical mobility in the maintenance of balance and equilibrium. Consequently, its lack thereof, in causing dizziness, is also described. While the relevance of cervical hypomobility to dizziness has been previously described, the possible correlation between cervical hypomobility and dependent postures of the semicircular canals is brought to light. Functional and postural compensations caused by cervical hypomobility which may in turn favor potential otoconia displacement, is described as a speculation. A case study relevant to this speculation is presented. Further research is needed to support and validate this speculation. The importance of restoring functional cervical mobility during routine vestibular rehabilitation is emphasized.
