The patient number 4 is positioned supine with her head in 30-degrees of anteflexion on a four-inch-thick pillow. The head-rolling maneuver in the supine position is executed. The head is quickly rolled towards the healthy side, and slowly towards the affected ear for 8 times. By the virtue of the generated inertial forces, quick movement is expected to detach the otoconial debris adherent to the cupula on its canal side, and the slow movement is presumed to facilitate the migration of the detached otoconial debris towards the utricle under the effect of gravitational forces.
