Volitional control of the upper esophageal sphincter with high‐resolution manometry driven biofeedback

摘要

IntroductionDysfunction of the upper esophageal sphincter (UES) is associated with swallow dysfunction and globus pharyngeus. Although volitional augmentation of the UES has been previously documented, the ability of individuals to control UES pressure with high‐resolution manometry (HRM) driven biofeedback has not been assessed.
