Session Time: 1:15pm-2:45pm
Location: Agora 3 West, Level 3
Objective: To determine: 1.If acoustic speech analysis can be a method of oropharyngeal dysphagia detection. 2.Which acoustic parameters and to what extent correlate with fiberoptic endoscopic examination of swallowing (FEES) findings. 3.Is it possible to assess the level of swallowing impairment with the use of speech analysis.
Background: Oropharyngeal dysphagia can occur even in 90% of patients with Parkinson’s disesase (PD). Swallowing disorders may result in malnutrition or even aspiration pneumonia, a leading cause of death in this population. FEES remains a ‘gold standard’ in dysphagia detection, however its accessibility is still insufficient. So far, little is known about speech and swallowing correlations; few recently published research suggest possible link.
Method: 25 patients with clinical diagnosis of PD (12 females, 13 males) aged 36 to 82 underwent FEES and speech acoustic analysis, both during ‘ON’ phase. They were divided into 3 groups according to the assessed level of oropharyngeal dysphagia. The results of speech analysis, using DiagnoScope software, were compared within the groups and the differences were statistically analyzed.
Results: Obtained results revealed the most significant correlation (p<0,05) with the following acoustic parameters: residual to harmonic (R2H), unharmonic to harmonic (U2H), efficiency factor (EF) and presence of oropharyngeal dysphagia. Post hoc analysis showed possible use of acoustic analysis in evaluation of the level of swallowing impairment (R2H, EF).
Conclusion: Acoustic speech analysis is a promising alternative assessment method of swallowing. In this study, R2H, U2H and EF were statistically significant parameters of dysphagia presence and its advancement. Further study is required.
