Abstract The study investigated the effects of pallidotomy on speech intelligibility and motor speech function in patients with Parkinson disease. The speech intelligibility of a group of 12 subjects was assessed prepallidotomy and three months postpallidotomy. Results revealed a significant reduction in sentence intelligibility postpallidotomy for the 12 subjects. A subgroup of four subjects underwent a battery of physiological assessments to evaluate respiratory, laryngeal, velopharyngeal, and tongue function pre- and postpallidotomy. Physiological changes in motor speech function evident postpallidotomy were either negative or nonexistent in the majority of speech subsystems, with improvements noted in some components of the speech mechanism. High inter- and intrasubject variability was apparent across the four subjects. Results are discussed in relation to the possible role of the globus pallidus in motor speech control.
