title: "White coat effect" induced by therapist's presence during speech therapy for stroke rehabilitation: a single case study.
abstract: The excessive pressor response triggered in patients by an alerting reaction to a doctor's presence has been termed the "white coat effect." A 68-year-old man with verbal apraxia after multiple lacunar infarctions was referred to the hospital for speech rehabilitation. He experienced difficulty in talking with the speech therapist during therapy sessions but not when talking with his friends or family. Because the therapist's presence was stressful to the patient, it was considered that his anxiety might produce an excessive increase in blood pressure. Blood pressure monitoring was performed during 2 separate days of speech therapies consisting of two sessions each. In one session, therapy was directed by the therapist; in the other, therapy was self-directed. The therapist-directed approach substantially increased both systolic and diastolic blood pressures, whereas the self-directed therapy slightly increased only systolic pressure. It was concluded that the excessive pressor response seen in this patient during therapist-directed speech therapy resulted from the white coat effect induced by the therapist's presence.
