Transcutaneous Electrical Stimulation and Dysphagia Rehabilitation: A Narrative Review

Abstract EN

Transcutaneous electrical stimulation (TES) was introduced as a modality for dysphagia rehabilitation more than a decade ago.

The underlying premise of this modality is improving the structural movements and enhancing neural activation based on stimulation-induced muscle contractions.

However, divisive evidence exists regarding the effectiveness of this treatment modality.

This manuscript reviews current evidence regarding the effects of transcutaneous electrical stimulation (TES) on clinical and physiological aspects of swallowing function.

Furthermore, this narrative review delineates the knowledge gap in this area and recommends future research roadmap.

This review gives a comprehensive picture regarding current knowledge of TES to practicing speech and language pathologists and interested researchers.

It highlights the need for more robust studies in this area.

It also encourages researchers to focus more on the physiologic studies to understand the physiologic underpinning behind this treatment modality.
