The most effective repositioning treatment for posterior canal BPPV is the therapist-performed Epley combined with home-practiced Epley maneuvers. Devices such as the DizzyFIX can help users conduct the Epley maneuver at home, and are available for the treatment of BPPV. Lempert maneuver or Roll maneuver
For the lateral (horizontal) canal, resulting in horizontal nystagmus, the Lempert maneuver has been used for productive results. It is unusual for the lateral canal to respond to the canalith repositioning procedure used for the posterior canal BPPV. Treatment is therefore geared toward moving the canalith from the lateral canal into the vestibule.The roll maneuver or its variations are used, and involve rolling the person 360 degrees in a series of steps to reposition the particles. This maneuver is generally performed by a trained clinician who begins seated at the head of the examination table with the person supine There are four stages, each a minute apart, and at the third position the horizontal canal is oriented in a vertical position with the persons neck flexed and on forearm and elbows. When all four stages are completed, the head roll test is repeated, and if negative, treatment ceases. Deep head hanging maneuver
For the superior ( also called anterior ) semicircular canal, resulting in vertical nystagmus, the Deep head hanging maneuver is used. The patient lays down on their back on a bed with their head overhanging the bed. In the first step the head is turned as backward (hanging) as possible.
