Treatment with the TRV-chair. Potentiated Epley's maneuver (a-h) and the dynamic barbecue roll maneuver (i-l). (a) Patient positioned in the TRV-chair with VNG Goggles in place (vision denied). (b) The patient is placed upright and turned 45 degrees to the left in the yaw axis as part of the initial position for a left Dix-Hallpike test. (c) The patient is moved backwards into a position corresponding to the left Dix-Hallpike test position. (d-g) The patient is continuously rotated 45 degree towards the healthy ear following treatment in every position. (c-g) Please note that 10 shocks were applied in every of these five positions to add kinetic energy during repositioning. (h) The patient is reverted to the upright position. (i) Starting position of the dynamic barbecue roll maneuver for treatment of right horizontal cupulolithiasis. (j-l) The patient is rotated 360 degrees ten times towards the healthy ear with a combination of accelerations and decelerations in the roll axis (in this case treatment of right sided lateral cupulolithiasis).
