Effectiveness of Chewing Technique on the Phonation of Female Speech-Language Pathology Students: A Pilot Study.

摘要: Summary Objectives The purpose of this study was to determine how use the vocal facilitating technique, chewing, affected phonation speech-language pathology (SLP) students. Study Design A pretest-posttest randomized control group design used. Methods Twenty-seven healthy female SLP students were randomly assigned into either an experimental or a group. practiced chewing exercises across 18 weeks, whereas received no techniques. Both groups completed pre- and post- objective voice assessment measures (aerodynamic measurement, acoustic analysis, range profile, Dysphonia Severity Index). Differences between post-data compared using independent sample t test. Results Compared group, resulted in significant decrease jitter noise-to-harmonic ratio (NHR), increase fundamental frequency ( f o ), expansion Index (DSI). Shimmer maximum time (MPT) not significantly different groups. Conclusions results pilot suggest that may improve
