We performed three maneuvers of the positional test in supine patients: (1) body maneuver , in which patients turned only the body to one side while keeping the head as still as possible; (2) head-only maneuver , in which patients turned only the head to one side while keeping the body still; and (3) head and body maneuver , in which patients turned the head and body together to one side. The nystagmus provocation rates of those three maneuvers among 86 vertiginous patients were 9% in the body maneuver, 16% in the head-only maneuver, and 33% in the head and body maneuver, respectively. We proved that performing the positional test by turning the head and body together is very effective in provoking positional nystagmus
