ABSTRACT

Objective To explore the effect of Omaha system combined with voice training in the treatment of patients with functional vocal dyspraxia caused by incomplete glottic closure. Methods From January 2017 to December 2017,eighty-eight patients with vocal dystonia due to glottic insufficiency who were treated in the Second Hospital of Shaoxing were randomly divided into control group and observation group by random number table method, with 44 cases in each group.The control group was treated with voice training.The observation group was given Omaha system measures on the basis of treatment in the control group.After 8 weeks,the therapeutic effects,GRBAS index scores,VHI scores,changes in acoustic parameters,and laryngoscope scores were compared between the two groups. Results After treatment,the total effective rate of the observation group (90.91% ) was significantly higher than that of the control group(59.09% ) (χ2 =9.317,P<0.05).After treatment,the scores of total deafness,roughness and other indicators were significantly reduced in both two groups,and the scores of GRBAS in the observation group were significantly lower than those in the control group(t=8.674,P<0.001;t=2.169,P=0.032;t=2.489,P=0.014;t=32.832,P<0.001;t=9.381,P<0.001).After treatment,the index scores and total VHI scores of both two groups were significantly decreased,and the scores of the observation group were significantly lower than those of the control group(t=2.222,P =0.028;t =3.144,P =0.002;t =2.003,P =0.048;t =5.763,P <0.001). After treatment,the maximum phonation time(MPT),basic frequency( Jitter),and lowest sound intensity( I-Low) were significantly reduced in the two groups, which in the observation group were significantly lower than those in the control group( t =4.037,P <0.001;t =4.789,P <0.001; t =4.717,P <0.001). The highest basic frequency (F0-High) and DSI index significantly increased in both two groups,which in the observation group were signifi-cantly higher than those in the control group(t=4.497,P<0.001;t=4.794,P<0.001).Conclusion The combi-nation of Omaha system measures and voice training can significantly improve functional vocal disturbances caused by glottic insufficiency,significantly improve the quality of patients＇voices,improve glottic closure,and contribute to the recovery of patients＇voices.It is worthy of promotion in clinical practice.
