Translating High-Resolution Manometry From Research to Clinical Practice

Abstract

Purpose High-resolution manometry (HRM) is a developing evaluation and treatment modality within the scope of speech-language pathology clinical practice. HRM offers pressure measurement over time that can capture details of pharyngeal and upper esophageal sphincter function unattainable with current dysphagia imaging modalities. As the technology is being adapted from esophageal application to use in the pharynx, understanding the strengths and limitations of HRM is paramount to building valid models for clinical use. Conclusion This review of HRM translation from research to clinical practice aims to introduce the speech-language pathologist to this novel evaluation and treatment apparatus.

Using high resolution manometry impedance to diagnose upper esophageal sphincter and pharyngeal motor disorders

“…Deglutitive disorders lead to dysphagia symptoms in a wide range of pathologies 1 that impair relaxation and opening of the upper esophageal sphincter at the pharyngo‐esophageal junction (UES disorder) or weaken the contractility of all or part of the pharyngo‐esophageal segment musculature (propulsive disorder). The diagnosis of deglutitive disorders requires clinical swallow assessment for which high‐resolution manometry impedance (P‐HRM‐I), a catheter‐based diagnostic, is emerging in clinical gastroenterology, otolaryngology, and speech pathology practice 2–7 …”

“…The diagnosis of deglutitive disorders requires clinical swallow assessment for which high-resolution manometry impedance (P-HRM-I), a catheter-based diagnostic, is emerging in clinical gastroenterology, otolaryngology, and speech pathology practice. [2][3][4][5][6][7] Current recommendations on P-HRM-I assessments of oropharyngeal swallowing include guidance on deriving eight physiological measures that define pharyngeal contractile vigor as well as UES pressure relaxation and opening. 8 These parameters have already been helpful for characterizing the physiological and potential rehabilitative effects of swallowing exercise, 9,10 sensory stimulation, 11 and novel surgical interventions.…”
