valsalva maneuver for vertigo
An example of dizziness induced by inner ear pressure changes might be dizziness associated with the Valsalva maneuver. This is a straining maneuver that increases pressure in the spinal fluid and inner ear perilymph space. Superior canal dehiscence is the main cause of Valsalva induced dizziness. An example of dizziness induced by middle ear pressure fluctuation is alternobaric vertigo -- such as occurs in people who can clear one ear, but not the other.(Tjernstrom 1974; Tjernstrom 1974; Tjernstrom 1974; Klingmann, Knauth et al.
