Session Title: Parkinson’s Disease: Clinical Trials, Pharmacology And Treatment
Session Time: 1:15pm-2:45pm
Location: Exhibit Hall C
Objective: Dysphagia occur frequently in Parkinson’s disease. It include usually some problems to pharyngeal phase.
Background: The aim of this study was to compare the importance of ultrasonography in the evaluation of swallowing functions in Parkinson’s disease (PD) patients with dysphagia by using ultrasonographic, endoscopic and electrophysiological methods
Methods: A fourteen female dysphagic PD patient s who had a medically stable condition for at least 2 years, without disorders known to cause dysphagia such as stroke, brain injury or thyroidectomy, or without severe cognitive impairment, and 13 age- and sex-matched healthy volunteers without metabolic, endocrine disease or swallowing complaints were included in the study.
Bedside evaluation tests (bedside neurological examination, dysphagia evaluation scale and total swallow score), eating assessment tool-10 (eat-10) and fiberoptic endoscopic evaluation (penetration aspiration scale) were used to assess swallowing functions in patient group. In both the patient and the control group, electrophysiological methods were used to determine the durations of oral , pharyngeal and total swallowing phases and the ultrasonographic evaluations were used to measure resting thickness of massater, temporalis, orbicularis oris, tongue, geniohyoid and anterior digastric muscles, and contractile thickness of masseter muscles and hyoid-thyroid distance of movement .
Electrophysiological and ultrasonographic evaluation parameters of both groups were compared.
Results: At the end of the study; mild-moderate dysphagia was detected in 10 patients (57.1%) endoscopically. Electrophysiologically, in the patient group, there was a significant prolongation of the oral and the total swallowing phases compared to the control group. Significant decrease in the thickness of the oral phase and the anterior digastric muscles, and significant increase in hyoid thyroid distance during swallowing were found by ultrasonographic evaluations in the patient group (p <0.05).
Conclusions: Oral phase involvement in patients with Parkinson’s disease may cause dysphagia, and endoscopic evaluation of the pharyngeal phase may not be sufficient to detect this. Ultrasonographic evaluationas a simple and non-invasive method can be used as an adjunctive method to detect dysphagia in PD patients.
