Abstract
It has been acknowledged that for many patients with spastic dysphonia, reflexive phonation remains essentially free of the spasticity that characterizes this disorder. The purpose of this paper is to document the extent to which various phonatory tasks change the patient's voice. We retrospectively reviewed 37 patients with spastic dysphonia evaluated at the Center for Communication Disorders of Lenox Hill Hospital, New York, between 1977 and 1981. The patients' responses to various phonatory tasks were observed. These tasks were grouped into the following ten categories: noncommunicative vocalization, primitive communication, speech superimposed on noncommunicative phonation, communicative phonation with varied mode of vocal fold vibration, normal communicative phonation with unusual pitch, normal communicative phonation with unusual emphasis, normal communicative phonation with normal laryngeal adjustments, use of the vocal folds in an artistic manner, speech in which normal auditory feedback was eliminated, and speaking with whisper which was not associated with vocal fold vibration. The results are summarized as follows: 1) whispered speech always resulted in an improvement of the symptom, in most cases markedly; 2) there was a tendency for a task that was more effective in reducing spasticity to be reduced in communicative function; 3) there was a tendency for a task that was more effective in reducing the spasticity to deviate more from the normal mode of phonation; and 4) there were some patients in whom an improvement occurred with elimination of auditory feedback.
