title: Vestibulogenic imbalance.
abstract: Vestibular lesions may cause imbalance that long outlasts vertigo. Photographic analysis in five cases showed defects not only of the tilting reactions, which are of labyrinthine origin, but also of certain other postural reactions, notably the counterpoising and protective stepping reactions. All of these reflexes are unconscious and consequently such patients are rendered unstable in several ways simultaneously and may have difficulty describing their symptoms.
