Visual feedback of vocal intensity in the treatment of hysterical aphonia.
This case report describes the successful though temporary removal of a hysterical aphonic symptom in a 49-year-old male patient by using visual feedback of changes in vocal intensity. Following symptom removal the patient experienced considerable emotional distress due to a number of factors. His aphonia returned and has proven resistant to subsequent intervention. At a 1-year follow-up his condition was found to be unchanged. The case is discussed in relation to the common controversy over the wisdom of symptomatic treatment for hysterical reactions, and a practical means of resolving the disagreement is considered.
