A preliminary study of different training methods and intensity on speech effect in preschool patients with re-paired cleft palate
Objective:To investigate influence of different training methods and intensity on speech effect in pre-school children with repaired cleft palate.Methods:A total of 40 pediatric patients aged 4～6 years old who achieved velo-pharyngeal competence after primary incomplete cleft palate repair from June 2021 to December 2022 in Nanjing Stomatologi-cal Hospital were included in our study.They underwent online or offline(outpatient)speech training after surgery,who were randomly divided into 2 groups:group A(online training group),group B(offline or outpatient training group).Within each group,they were further divided into low-intensity(once per week)and high-intensity training groups(three times per week).All patients underwent a training method of changing the position of articulation using phonological therapy,with a duration of 0.5 hours per session and 12 sessions per course,lasting for 2 sessions.Speech intelligibility(SI)value and compensatory ar-ticulation degree(CA)were evaluated to analyze the speech effects of different training methods.Results:After online group training,the SI increased from 63.25%to 91.55%(P<0.001),CA increased from 4.30 to 5.50(P<0.001).After offline group training,the SI increased from 63.15%to 93.05%(P<0.001),and CA increased from 4.35 to 5.90(P<0.001).The SI of the offline group after training was 93.05%,slightly higher than that of the online group at 91.55%(P=0.041)and the degree of CA was 5.90 higher than that of the online group(5.50)(P=0.095).In high-intensity training group,the SI was 93.75%,while the SI was 90.85%in low-intensity training group(P<0.001).After high-intensity training,the CA was 6.00,while after low-intensity training,the CA was 5.40(P=0.01).Conclusion:There was no significant difference in the improvement of compensatory articulation disorders between the online and offline groups after training,while the offline group had slightly better speech clarity than that of the online group.Increasing training intensity can improve speech performance.
