Horizontal HSN<\/jats:styled-content> was classified as monophasic or biphasic and paretic or recovery.

Paretic HSN<\/jats:styled-content> with the nystagmus towards the lesioned side was the most common type in VN<\/jats:styled-content> and MD<\/jats:styled-content>; however, recovery HSN<\/jats:styled-content> with the nystagmus towards the intact side could be rarely observed especially in patients with MD<\/jats:styled-content> or compensated VN<\/jats:styled-content>. Vertical nystagmus could be combined with horizontal HSN<\/jats:styled-content>, and upbeat HSN<\/jats:styled-content> was observed in most (83%) of the patients with acute VN<\/jats:styled-content>, but downbeat HSN<\/jats:styled-content> was common in follow\u2010up VN<\/jats:styled-content> (83%), MD<\/jats:styled-content> (97%) and MV<\/jats:styled-content> (85%). Weak perverted HSN<\/jats:styled-content>, which is assumed to be a central nystagmus, was rarely observed in MD<\/jats:styled-content> and MV<\/jats:styled-content> (6\u20139%), but not in VN<\/jats:styled-content>.<\/jats:p><\/jats:sec>Conclusions<\/jats:title>Head\u2010shaking nystagmus (HSN<\/jats:styled-content>) in horizontal plane is a valuable tool in the assessment of vestibular imbalance. Common observation of upbeat HSN<\/jats:styled-content> in acute VN<\/jats:styled-content> and downbeat HSN<\/jats:styled-content> in follow\u2010up VN<\/jats:styled-content>, MD<\/jats:styled-content> and MV<\/jats:styled-content> suggests that vertical components are possibly related to the involvement of vestibular apparatus and compensation.
