Effects of glossopharyngeal breathing on speech and respiration in multiple sclerosis: a case report

Abstract

This case report describes the effects of glossopharyngeal breathing on respiration and speech in a patient with tetraplegia due to multiple sclerosis. Glossopharyngeal breathing is a technique where air is insufflated with the glossopharyngeal muscles, to increase vital capacity. Results from follow-up assessments up to 20 months after intervention showed that (1) the patient’s speech and respiratory function with glossopharyngeal breathing improved over time, (2) the patient’s respiratory function without glossopharyngeal breathing deteriorated over time (possibly because of a severe cold), and (3) at each assessment, the patient’s speech and respiratory function was better with glossopharyngeal breathing than without it.
