Effect of Lee-Silverman voice treatment on electroglottography parameters and speech function in Parkinson's disease patients with dysarthria
Objective To explore the effect of Lee-Silverman voice treatment (LSVT) on language re-habilitation of dysarthria in Parkinson's disease (PD).Methods A total of 84 patients with PD dysarthria ad-mitted to our hospital from February 2019 to February 2022 were selected as the research objects.According to the random number table method,they were divided into observation group and control group,with 42 cases in each group.The control group received routine speech rehabilitation training,and the observation group re-ceived LSVT for four weeks.The scores of Western Aphasia Battery (WAB) and Aphasia Quotient (AQ) be-fore and after intervention were compared between the two groups,and the differences of electroglottographic parameters such as jitter,F0,shimmer,normalized noise energy (NNE) and harmonic noise ratio (HNR) were compared between the two groups.Results Before intervention,there was no significant difference in WAB scores (listening comprehension,repetition,spontaneous speech,naming) and AQ scores between the two groups (P>0.05).After intervention,the above scores of the two groups were significantly improved,and the observation group was higher than the control group,the difference was statistically significant (P<0.05). Before intervention,the jitter,F0,shimmer,NNE,HNR of vowels "a""i""u" in the two groups were not sta-tistically significant (P>0.05).After intervention,the above-mentioned electroglottic parameters of the two groups were significantly improved.The jitter and NNE of vowels "a""i""u" in the observation group were lower than those in the control group,and the HNR was higher than that in the control group,the differences were statistically significant (P<0.05).Conclusion LSVT can improve the electroglottographic parameters and speech function of patients with PD dysarthria,and the language rehabilitation effect of PD dysarthria is obvious.
