Techniques for evaluating swallowing Flashcards
3 non-imaging techniques
bedside/clinical swallow eval
electromyography (EMG)
electroglottography (EGG)
3 imaging techniques
fees: fiberoptic endoscopic evaluation of swallowing
ultrasound
videofluoroscopy/MBS study
record of muscle activity from electrodes
biofeedback
EMG (electromyography)
reflects amount of current flowing through neck
tracks VF movement
EGG (electroglottography)
uses sounds of swallowing by placing microphone/stethoscope to neck
cervical auscultation
listen for “click” of opening of eustachian tube and “clunk” associated with CP opening for timing of swallow
cervical auscultation
provides info on medical dx/hz, h/o swallowing disorder
provides medical status including respiratory/nutritional status
clinical/bedside swallow eval
provides: oral anatomy respiratory function labial control lingual control palatal function
clinical/bedside swallow eval
provides:
pharyngeal wall contraction
laryngeal control
ability to follow directions
