Asprella Single Maneuver

就是一个简单的躺下动作，不管是外半规管还是后半规管BPPV，都可能诱发眩晕/眼震，所以其判读比较复杂，优点是减少诊断试验次数，减轻诊断过程诱发的眩晕不适。

操作步骤
Asprella Single Maneuver performed to diagnose both LSC and PSC BPPV: a brisk change from seated to supine position, under videonystagmoscopic control.

When a rotatory nystagmus is evoked the head is turned 45° to the right if the nystagmus is counterclockwise and to the left if it is clockwise; therefore, the bed head is lowered rapidly so that the patient goes to the Dix-Hallpike position.
If the nystagmus persists or becomes more intense, then the diagnosis of the PSC-BPPV is confirmed and Epley manoeuvre is performed.
Should a horizontal nystagmus occur, LSC-BPPV will be diagnosed: e.g. a right nystagmus may indicate either a left geotropic form or a right apogeotropic form. In fact, in the supine position, the LSC is on a vertical plane and, therefore, due to the brisk deceleration caused by the manoeuvre, the otoliths are pushed downwards; if they are in the posterior arm, they float towards the utricle, but if they are in the anterior arm, they float towards the ampulla
