Figure 1

Semont maneuver (A–D): this CRP is initiated with the patient upright and turned 45 degrees in the yaw axis towards the affected side (A). Then the patient is moved 120 degrees backwards in the roll axis on the affected side (B). This position is kept for 30 s. Then the MRC is rotated fast in the roll axis a total of 240 degrees towards the healthy side (C). This position is also kept for 30 s. The CRP is completed when the patient is positioned upright from this position (D). Epley maneuver (E–H): this CRP is initiated with the patient upright and turned 45 degrees in the yaw axis towards the affected side (A). Then the patient is moved 120 degrees backwards in the roll axis (E). This position is kept for 30 s. Then the patient is turned 90 degrees towards the healthy side in the yaw axis (F). This position is kept for 30 s. An additional 90 degree turn towards the healthy side follows and this position is again held for 30 s (G). The CRP is completed when the patient is positioned upright from this position (H). The 360-degree somersault maneuver (I–L): this CRP is initiated with the patient upright and turned 45 degrees in the yaw axis towards the affected side (A). Then the patient is moved 90 degrees backwards in the roll axis on the affected side. This position is kept for 30 s (I). Then the patient is then continuously moved backwards in the pitch axis for an additional 270 degrees (J–L). The CRP is completed when the patient is positioned upright in the starting position and has been rotated a total of 360 degrees backwards (L). The total duration of the 360-degree rotation was approximately 1 minute. Please note that all illustrations show treatments targeted left-sided posterior BPPV and please also note that the initial position with the Epley maneuver and the 360-degree somersault maneuver is not shown but is the same as the starting position with the Semont maneuver (A). Please also note that an upright starting position with the patient facing straight left is a prerequisite for correct repositioning if following the above mentioned instructions.
