Focal muscle vibrations improve swallowing in persistent dysphagia after traumatic brain injury: A case report.

Dysphagia is a common complication following traumatic brain injury (TBI), and it is related to an increased risk of malnutrition, pneumonia, and poor prognosis. In this article, we present a case of TBI with persistent dysphagia treated with focal muscle vibration. A 100 Hz and 50 Hz vibratory stimuli were applied over the suprahyoid muscles and tongue (30 min twice a day; five days a week; for a total of four weeks) in addition to the conventional therapy to quickly recover swallowing and avoid the possibility of permanent deficits.
