Positioning testing nystagmus was present in 2% to 100% of patients during Dix-Hallpike (DH) and in 7.9% to 37.5% of patients during the supine head roll testing (SHRT). Nystagmus direction, when present during DH and SHRT, included horizontal, vertical, and torsional nystagmus. Positional testing nystagmus was present in 0% to 100% of patients during upright positional testing and in 42.1% to 95.5% of patients during supine positional testing. Horizontal, vertical, and torsional nystagmus in upright positional testing and direction-changing nystagmus in supine positional testing were observed. Unilateral weakness was present in 0% to 100% of patients; however, most studies reported a rate of &lt;50% of unilateral weakness in tested patients. During vHIT, both abnormal gain and corrective saccades were observed, with the latter being more common.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion and Relevance<\/jats:title>\n                    <jats:p>VM can present with ocular movement patterns seen in both central nervous system disorders and peripheral vestibular system disorders on vestibular testing.
