Interventions

  • Caloric Vestibular Stimulation — OTHER
    Cold water creates a convection current in the semicircular canal of the vestibular apparatus, leading to brief (\<3 min) and typically well tolerated sense of rotational movement. Similar stimulation is routinely used in standard vestibular diagnostic testing.

Study Details

This study investigates whether caloric vestibular stimulation can modulate a measure of insight in obsessive-compulsive spectrum disorders.

Arms

  • Experimental: right cold caloric vestibular stimulation
    OCRD participants in this arm will receive an approx 60 second infusion of distilled cold(4)c water in their right external ear canal, with before and after measures of OCRD symptom severity and insight.
  • Experimental: left cold caloric vestibular stimulation
    OCRD participants in this arm will receive an approx 60 second infusion of distilled cold(4)c water in their left external ear canal, with before and after measures of OCRD symptom severity and insight.

Primary Outcome Measure

change in clinical insight as measured by the Brown Assessment of Beliefs (BABS). [ Time Frame: 1 hour ]
