| Abstract: | ObjectiveTo analyze if there is an influence of the body position and emission number in the results of the maximum phonation times (MPT) of adults without vocal complaints.Materials and methodsThis is an observational, analytical and cross-sectional study. Sixty subjects participated: 30 men and 30 women without vocal complaints. Subjects were instructed to stay in orthostatic or sitting position, according to the collection's order that was selected. The first 30 subjects were evaluated in order number 1 (sitting and orthostatic) and the other 30 subjects were evaluated in order number 2 (orthostatic and sitting), with a 5-minute interval between the emissions in the two positions. The MPT of vowels /a/, /i/, /u/, fricatives /s/ and /z/, and numbers were collected. After this, the subjects were instructed to do the same emissions mentioned above, but in another position (orthostatic or sitting). The values of MPT were statistically analyzed with both the Analysis of Variance (ANOVA) paired measures test to three criteria and the Tukey Test (P < 0.05).ResultsThere was no difference between the MPT obtained in both positions. Males had all MPT higher than females. Regarding the emission number, there were differences for both sexes in the MPT of the vowel /a/ and the number counting.ConclusionIn general, it is concluded that there is no influence of body position in the results of voice temporal measures, but the sex and the number of the emissions influence the result of the MPT. |
