Rumination Swallowing in Limb-Girdle Muscular Dystrophy.

Patients with limb-girdle muscular dystrophy (LGMD) may develop swallowing disorders as the disease progresses. We detected a novel swallowing pattern in patients with LGMD, characterized by unique findings such as a rumination-like behavior, where food reaches the vallecula and piriform sinuses and then is regurgitated back into the oral cavity, re-chewed, and swallowed again. We termed this swallowing pattern "rumination swallowing." In this report, we describe a case of rumination swallowing, as observed through a videofluoroscopic (VF) examination, in a 56-year-old patient with LGMD.
