Oral vs. pharyngeal dysphagia: surface electromyography randomized study

Abstract: Background: A clear differential diagnosis between oral and pharyngeal dysphagia remains an unsolved problem. Disorders of the oral cavity are frequently overlooked when dysphagia/ odybophagia complaints are assessed. Surface electromyographic (sEMG) studies were performed on randomly assigned patients with oral and pharyngeal pathology to evaluate their dysphagia complaints for the sake of differential diagnosis.Methods: Parameters evaluated during swallowing for patients after dental surgery (1: n = 62), ora… Show more

“…We believe that such choice of the epoch duration is one of the reasons that our recognition rate is substantially higher than per epoch accuracy of 70% reported in [23] where the authors used a 0.25s epoch which cannot cover a complete swallow. Although our study excluded dysphagic subjects, we may anticipate that recognition of longer-than-normal dysphagic swallows [36] may benefit from a longer epoch.…”

“…sEMG signals were recorded using multiple channels of the VikingQuest Systems (VikingQuest EMG and Master Software V8.1 or newer, 2005; Nicolet VIASYS Healthcare, Madison, WI). The inter-electrical distance of the electrodes was not less than 10 mm, [ 11 , 19 , 21 ] and placed by a senior experienced physician.…”

“…Vaiman and colleagues, a team heavily involved in sEMG research, use another option: the Sys/3 4-channel computer-based EMG system from NeuroDyne Medical [7]. Although this system is likely more cost-effective than the aforementioned options, it remains complicated such that the typical SLP may not be able to set up this equipment easily and without the aid of qualified personnel.…”
