Evaluating the Therapeutic Application of Neuromodulation in the Human Swallowing System

Abstract

In the last two decades, the focus of neurogenic dysphagia management has moved from passive compensatory strategies to evidence-based rehabilitative approaches. Advances in technology have enabled the development of novel treatment approaches such as neuromodulation techniques, which target the promotion of neurological reorganization for functional recovery of swallowing. Given the rapid pace of development in the field, this review aims to summarize the current findings on the effects of neuromodulation techniques on the human swallowing system and evaluate their therapeutic potential for neurogenic dysphagia. Implications for future clinical research and practical considerations for using neuromodulation in clinical practice will also be discussed.

Dysphagia and dementia: a ‘double dilemma’

“…Reflexive swallow behaviors, including the highly coordinated sequence of pharyngeal constriction, airway closure and opening of the upper esophagus, are critical. Damage to both cortical and subcortical areas can impact normal swallowing in multiple ways [1,2].…”
