Abstract
OBJECTIVE To verify whether the dimensions of different segments of the oropharyngeal cavity have different proportions between Parkinson's disease patients and vocally healthy subjects and investigate whether the measurements of these subjects' oropharyngeal geometry associate with their acoustic measurements of voice. METHOD Quantitative, descriptive, cross-sectional, and retrospective study with secondary data, approved by the Human Research Ethics Committee under no. 4.325.029. We used vocal samples and data from the oropharyngeal geometry of 40 subjects - 20 with Parkinson's disease stages I to III and 20 who formed the control group, matched for sex and age. Each group had 10 males and 10 females, mean age of 61 years (±6.0). Formant (F1, F2, and F3) and cepstral measures of the sustained vowel /ε/ were extracted and arranged in the database to determine their values using Praat software. The data were descriptively analyzed, with statistics generated with R software. The proportion of oropharyngeal geometry measurements was arranged by mean values and coefficients of variation. Pearson's linear correlation test was applied to relate voice parameters to oropharyngeal geometry, considering P < 0.05, and linear regression test, to justify F2. RESULTS The Parkinson's disease group showed a linear relationship between oral cavity length and F1 in males (P = 0.04) and between glottal area and F2 in females (P = 0.00); linear relationships were established according to age in both groups, and a regression model for F2 was estimated (R2 = 0.61). There was no difference between pathological and healthy voices; there was a difference in the proportional relationship of oropharyngeal geometry between the groups. CONCLUSION The proportional relationship of oropharyngeal geometry differs between the Parkinson's disease group and the control group, as well as the relationship between oropharyngeal geometry and formant and cepstral values of voice according to the subjects' sex and age.

Effect of Resonance Tube Technique on Oropharyngeal Geometry and Voice in Individuals with Parkinson's Disease. J Voice 2020; 35:807.e25-807.e32. [PMID: 32201236 DOI: 10.1016/j.jvoice.2020.01.025] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2019] [Revised: 01/17/2020] [Accepted: 01/23/2020] [Indexed: 10/24/2022]
Abstract
OBJECTIVE To verify the immediate effect of the flexible resonance tube vocal technique on the oropharyngeal geometry and vocal acoustic parameters of individuals with Parkinson's disease (PD) and to study the correlation between oropharyngeal geometry and the intensity and fundamental frequency (f0) parameters of the voice. METHODS Forty individuals participated-20 with PD and 20 healthy individuals, with a mean age of 60.95 (± 5.69) years. There were 10 men and 10 women in each group. All underwent pharyngometric analysis of the vocal tract and voice acoustics parameters before and after use of the vocal technique with a flexible resonance tube. RESULTS After the technique, there was a reduction in pharyngeal cavity volume only in females in the healthy group, a reduction in shimmer values in females in both groups and males in PD group and an improvement in noise parameters in females in the PD group. There was a negative correlation between vocal tract volume and intensity, between f0 and vocal tract volume, between f0 and oropharyngeal junction area, between f0 and oral cavity volume as well as a positive correlation between oral cavity length and f0. CONCLUSION The vocal technique with the flexible resonance tube applied to individuals with PD improved the subjects' voice quality in the perceptual and acoustic voice parameters. Regarding the oropharyngeal geometry, it was possible to observe its correlation with the parameters of vocal intensity and frequency in the studied population.
