Drs. Kuhn and Belafsky have completed research that suggests that volitional control of the UES is possible with biofeedback. Patients with a high resolution manometry catheter in their pharynx who were placed in front of a biofeedback monitor were able to significantly increase and decrease their baseline UES pressure by 86 and 23 percent respectively. This work may have significant implications in the treatment of oropharyngeal dysphagia, gastroesophageal and laryngopharyngeal reflux, and globus pharyngeus.
