The half-somersault maneuver was devised by Dr. Carol Foster (Foster et al. 2012).
The Figure below shows the right-sided Foster maneuver for treating right-sided posterior canal benign paroxysmal positional vertigo, as illustrated in the original paper by Foster and colleagues (Foster et al. 2012).
Foster and colleagues (Foster et al. 2012) describe the half-somersault maneuver for treating right-sided posterior canal BPPV as follows:
- The patient kneels on all fours, then tilts the head upward and backward.
- The somersault position is assumed (with the torso tilted forward, and the head/neck inclined toward the knees), with the chin tucked as far as possible toward the knees.
- The head is turned about 45 degrees toward the affected (right) side, facing that side’s elbow.
- While maintaining the head 45 degrees rotated toward the affected (right) side (relative to the torso), the head is raised to the level of the shoulders.
- The head is raised to a fully upright position.

The Foster maneuver has been studied in multiple prospective randomized trials:
- Against the Epley maneuver (Foster et al. 2012; Khaftari et al. 2021).
- Against the Brandt-Daroff maneuver (Jaffar et al. 2023).
