Objective: To validate the acoustic analysis as an auxiliary method in the evaluation of swallowing in patients with Parkinson’s disease.To validate the acoustic analysis as an auxiliary method in the evaluation of swallowing in patients with Parkinson’s disease.
Background: This is a diagnostic accuracy study of Doppler sonar associated with DeglutiSom® Software (Sonar Doppler / DeglutiSom®).
Method: Quantitative, transversal and double blind study. Patients were referred by the Department of Neurology and screened at the Movement Disorders Outpatient Clinic of the UFPR Hospital de Clínicas. A total of 248 patients were evaluated, and 91 volunteers with a diagnosis of Parkinson’s disease, with a mean age of 64.9 years (SD 7.7) years, 53.8% were male and 46.2% were male. women. In all, the mean duration of the disease was 12.6 years (SD 3.8) years. As the study was outlined.
Results: In agreement of the findings of the investigator and the judges with the results of the videofluoroscopy, the degree of agreement of the evaluators with the investigator is of 90.1%, being 4,4% the degree of partial agreement and 5.5% of discordance. Sensitivity resulted in (90%) and specificity in (90%). In the indicators for analysis of the validity of the method for screening dysphagia is high with sensitivity of 0.97 (97%) and specificity 0.91 (91%), predictive value (+) is 0.97 (97%) and value predictive value (-) of 0.91 (91%), with a method accuracy of 0.96 (96%). In the validity indicator of the aspiration screening method, the values are also high, with sensitivity of 0.90 (90%), specificity of 0.90 (90%), predictive value (+) of 0.82 (82%), predictive value (-) of 0.95 (95%) and accuracy of 0.90 (90%).
Conclusion: With the results obtained, we conclude that the method presents appreciable results in the screening of oropharyngeal dysphagia and acoustic signals of laryngotracheal aspiration.
