|Summary / Zusammenfassung||The general purpose of this study is to investigate whether chronic mechanical neck pain patients with or without subjective dizziness demonstrate evidence of vestibular dysfunction compared to patients with confirmed vestibular disease. In particular, signal changes related to threshold, latencies and amplitude for sound or click evoked VEMP tests will be analyzed using the Extraocular VEMP for saccule function and modified SCM for utricle function (Todd et al, 2008; Vanspauwen et al, 2006). The HIT will be used to assess the VOR for the presence or absence of catch-up saccades as a measure of semicircular canal function (Weber et al, 2008). The specific study questions are as follows:
Do chronic mechanical neck pain patients with subjective dizziness demonstrate abnor-malities of vestibular function as measured by the modified SCM VEMP (saccule), Ex-traocular VEMP (utricle) and HIT (semicircular canal) tests compared to patients with known vestibular disease?
Do chronic mechanical neck pain patients without subjective dizziness demonstrate ab-normalities of vestibular function as measured by the modified SCM VEMP (saccule) Ex-traocular VEMP (utricle) and HIT (semicircular canal) tests compared to patients with known vestibular disease?
Three groups of 20 participants each will be recruited to the study. All VEMP testing will be done at the University Hospital Zürich, Department of Neurology.
