Background: Swallowing difficulties or dysphagia is the main cause of aspiration pneumonia and death in patients with Parkinson's disease (PD). Although dysphasia occurs in 90% of patients with PD, there is insufficient evidence to support the effectiveness of behavioral speech therapy in this disease. Objectives: This study aimed to investigate the effect of a new telerehabilitation program that was a combination of speech and music therapy on dysphagia in patients with PD. Methods: This study was a 3-arm randomized controlled trial (RCT). Thirty-three subjects with PD (mean age, 58.88 years; 25 men and 8 women with complaints of swallowing problems) were randomly assigned to the combination therapy (including breathing, speech, voice, and singing exercises), conventional speech therapy, and music therapy groups. Each patient participated in 12 telerehabilitation sessions over 4 weeks. Swallowing Disturbance Questionnaire (SDQ) and Dysphagia Handicap Index (DHI), as the outcomes of this study, were evaluated 1 week before the first intervention session, 1 week after the last intervention session, and 3 months after the last evaluation. Results: The results showed a significant improvement in SDQ and all sub-tests (functional, physical, and emotional), as well as the total score of DHI in the combination therapy and conventional speech therapy groups after treatment (P < 0.05). Also, the music therapy group had a significant improvement in the SDQ score, emotional sub-test, and the total score of DHI (P < 0.05). The combination therapy group demonstrated a significant outperform in the SDQ score compared to the other 2 groups, as well as in all sub-tests and the total score of DHI compared to the music therapy group (P < 0.05). The combination therapy group also showed more improvement in all sub-tests, as well as the total score of DHI, compared to the music therapy group (P < 0.05). The results also indicated that the speech therapy group had a more significant effect on the physical sub-test of DHI compared to the music therapy group (P < 0.05). Conclusions: Although swallowing function improved in all 3 groups, this improvement was more in the combination therapy group than in the other groups. Therefore, it can be concluded that combination therapy has the potential to provide additional benefits for swallowing efficiency in this patient group. The results also suggest that the telerehabilitation method is feasible to deliver intensive therapy to individuals with PD to improve swallowing functions.
Objectives: Voice is influenced by personality. However, it is still questionable which acoustic features are influenced by personality traits. This study aimed to investigate the relationship between acoustic characteristics and personality dimensions. Methods: Thirty-three participants with dysphonia and 33 participants without dysphonia were recruited to take part in this cross-sectional study. Personality dimensions were evaluated by the revised NEO personality inventory, and acoustic characteristics by using the Praat software. The tasks included prolongation of the vowel /a/, expression of declarative and interrogative sentences, reading, and connected speech. The acoustic features included fundamental frequency range, jitter, shimmer, harmonic-to-noise ratio, intensity, and duration. SPSS V. 23 was used for statistical analysis. For correlation analysis, the Pearson and Spearman correlation coefficients were employed. Results: In individuals with dysphonia, a significant relationship was observed between personality dimensions and the following acoustic features: A. extraversion and intensity in connected speech (P=0.045) and the reading task (P=0.036); B. openness and shimmer in /a/ vowel prolongation (P=0.003); C. openness and the harmonic-to-noise ratio in /a/ the vowel prolongation task (P=0.017); and D. agreeableness and duration in expressing interrogative sentences (P=0.019). Discussion: In Persian-speaking participants with and without dysphonia, some acoustic characteristics were significantly correlated with the mean score of the personality test (revised NEO personality inventory). It seems that each voice feature is influenced by personality dimensions. This finding indicates that changes in acoustic characteristics of voice due to personality can be evaluated in laboratory and hearing examinations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
