Execution:
- Explain to the patient that his symptoms of vertigo might be reproduced and that he might feel nauseaus. Have a bucket at hand in cases it is needed
- Have the patient sit on the treatment bench in long sit with a pillow on the table to make sure that the patient’s neck will come into 20° of extension at step 3
- The examiner rotates the patient’s head 45° towards the side to be tested
- The patient is instructed to keep his eyes open and the examiner takes the patient backwards in a quick movement so that the patient’s neck is still rotated 45° and the neck is brought into 20° extension
- The patient’s eyes are observed for the latency (typically 5-20s), duration and direction of a possible nystagmus. The nystagmus usually fatigues within 60 seconds
Positive Outcome:The patient experiences vertigo with an upbeat nystagmus towards the affected side in case of posterior BPPV
