Videomanofluorometric Study in Amyotrophic Lateral Sclerosis

Abstract

Patients with ALS gradually face the danger of aspiration as decreases of oropharyngeal and hypopharyngeal swallowing pressure progress. Upper esophageal sphincter spasm occurs in some patients with ALS, and it is an important cause of aspiration. Both videofluoroscopic and manometric evaluation are necessary to assess these conditions, and they are quite useful for follow-up of swallowing function in patients with ALS.
