Surface Electromyography Biofeedback as an Adjuvant to Dysphagia Management: What It Is, What It Is Not, Why You Need It, and How to Get It

Abstract

Purpose: Surface electromyography (sEMG) has been used by speech-language pathologists (SLPs) as a biofeedback tool to enhance the benefits of dysphagia rehabilitation since as early as 1976. Despite being noninvasive and user-friendly, sEMG biofeedback is not widely adopted by clinicians, potentially due to challenges such as insufficient knowledge about its appropriate clinical applications and the burden of acquiring this technology for a busy clinician. This article aims to support SLPs in utilizing sEMG as a simple biofeedback tool for dysphagia management by providing an overview of the physiological and technological underpinnings of sEMG as well as practical guidance on interpreting sEMG signal, optimizing signal quality, and documenting findings at the end of a session. Moreover, the article emphasizes the vital role clinicians have in promoting ongoing innovation in their field by advocating for modern solutions. It provides a framework and examples of how to request technologies in the clinic to foster an environment of continuous improvement in the service provided to patients. Conclusion: This article aims to equip clinicians with the knowledge and skills necessary to utilize sEMG technology effectively and help their patients achieve optimal outcomes in dysphagia management.
