The head is slowly turned 90° toward the side where nystagmus is induced less intensely. Then the head is rotated 180° rapidly toward the opposite side. This article reports three cases of the ageotropic form of HC-BPPV that were cured by rapid head rotation. The three cases demonstrated that rapid head rotation was an effective maneuver to treat cupulolithiasis on the utricle side. It is recommended that rapid head rotation can be used for therapeutic diagnosis: If nystagmus subsides immediately after this maneuver, the diagnosis is cupulolithias is on utricle side. If nystagmus changes into the geotropic form, the diagnosis is cupulolithiasis on canal side or canalolithiasis in the anterior arm of horizontal semicircular canal. A repositioning maneuver for geotropic form can then be applied to treat these patients.

逆地眼振型水平半规管良性阵发位置性眩晕的3种耳石可能位置如下：水平半规管前臂的管耳石、管侧的顶帽沉石(canal side cupulo-lithias1s)与囊侧的顶帽沉石，本文报告3例以快速转头治疗逆地眼振型水平半规管良性阵发位置性眩晕成功的病例，显示快速转头法对囊侧的顶帽沉石具迅速有效的治疗效果，对於逆地眼振型水平半规管良性阵发位置性眩晕的治疗，作者建议先以快速转头作治疗性诊断，若病人马上复原，诊断为囊侧的顶帽沉石；若眼振转为向地型，则诊断为水平半规管前臂的管耳石或管侧的顶帽沉石，进一步再以向地型的耳石复位法治疗病人。
