Efficacy of Speech-Language Pathology Interventions for Globus Pharyngeus: A Scoping Review.

Objective: This scoping review aims to provide an overview of the literature investigating the efficacy of speech-language pathology (SLP) interventions in the treatment of globus pharyngeus (GP), identify gaps in knowledge, and guide future research.

Study Design: Scoping review.

Methods: Search terms were selected for five databases (PubMed, Embase, Web of Science, CINAHL, and Google Scholar). Inclusion criteria were broad and focused on any SLP intervention used to treat GP. Title and abstract and then full-text screening were performed.

Results: Of 420 unique abstracts identified, five studies met inclusion criteria. SLP interventions included explanation, education on normal swallow, laryngopharyngeal tension reduction exercises, "voice" exercises, neck/shoulder exercises, general relaxation, postural advice, diaphragmatic breathing, manual therapy, swallowing exercises, laryngeal hygiene, throat clearing suppression, stress management, and reassurance. All included studies reported statistically significant improvement in GP following SLP intervention based on the various outcome measures reported.

Conclusions: This scoping review yields very little high-quality evidence supporting the efficacy of SLP interventions in the treatment of GP. Further prospective studies with systematic investigations and the use of validated outcome measures are needed to study the efficacy of SLP interventions as either adjuvant or stand-alone treatment for GP.
