Multiple positional nystagmus suggests multiple canal involvement in benign paroxysmal vertigo.

Conclusion: Video-oculography demonstrates a higher occurrence of atypical positional nystagmus in patients with benign paroxysmal positional vertigo (BPPV). This includes anterior and horizontal canal variants and multiple positional nystagmus, suggesting combined lesions affecting several canals.

Objective: To analyse the video-oculographic findings of positional tests in patients with BPPV.
