How to perform (Herdman, S. J., 2007):

​

1. Patient moves quickly from sitting to side-lying position on the affected side.



2.  The patient turns the head so the nose is 45 degrees downward, and maintains this position for 2-3 minutes before returning to sitting.



Evidence:  

​Casani and associates report remission of symptoms in 75% of patients.
