ABSTRACT
Objective@#Analyzing the characteristics of consonant errors in children with functional dysarthria in different age groups and the effect of speech training provides a reference for clinical treatment. @*Methods @#This study followed medical ethics, and informed consent has been obtained from patients. Speech data from 388 patients with functional dysarthria were retrospectively studied. They were divided into two groups at the age of 6, namely, the preschool group (4-6 years old) of 226 patients and the school age group (6-13 years old, including 6 years old) of 162 patients. The characteristics of consonant pronunciation errors from four aspects were analyzed: average number of errors, pronunciation location, pronunciation method, and error type. One-on-one speech training was conducted, with a training frequency of once a week and once for 30 minutes. The training method was carried out in the order of phoneme training, syllable training, vocabulary training, sentence training, and short text and conversation training. The effects of speech training in the two groups were compared. @*Results@#Analysis by pronunciation location: both age groups had the highest frequency of errors in tongue tip posterior sounds; the school age group had the lowest error frequency for labiodental consonants, and the preschool group had the lowest error frequency for bilabial consonants. According to the analysis of pronunciation mode, both age groups had the highest error frequency of aspirated affricate and the lowest error frequency of nasal sound. Analysis by error type: both age groups are mainly characterized by substitution and omission. Compared with the preschool group, most consonants of patients in the school group tend to improve in terms of pronunciation location, pronunciation mode, and error types. Compared with the preschool group, the two types of errors-palatalization and lateralization-increased in frequency in the school group, but the trend of increased lateralization was not statistically significant. After 6.7 and 5.5 sessions of speech training, the pronunciation of the preschool group and the school-age group significantly improved; the cure rate of the school-age group was 84.9% (118/139), and that of the preschool group was 77.1% (91/118). There was no statistically significant difference in the cure rate between the two groups.@*Conclusion@# Functional dysarthria may improve with age, but it may not completely self-heal. Children of different age groups can achieve good treatment results through scientific and reasonable speech training.
ABSTRACT
Objective:To observe the effect of speech training based on mirror neuron theory on children with functional articulation disorder (FAD).Methods:Fifty children with FAD were randomly divided into a training group and a control group, each of 25. Both groups received 30 minutes of conventional speech training 5 times a week for 24 weeks, while the training group was additionally given 20 minutes of speech training based on mirror neuron theory simultaneously. Before and after the intervention, both groups were evaluated using the articulation speech ability assessment scale and the oral motor ability assessment scale.Results:Before the treatment, there were no significant differences between the 2 groups in any of the measurements. After the treatment, significant improvement was observed in all of the measurements for both groups, but at that point the training group′s articulation, motor ability of the lower jaw, tongue and lips were all significantly superior to the control group′s averages.Conclusions:Speech training based on mirror neuron theory can significantly improve the articulation, intelligibility and oral motor functioning of children with functional articulation disorder.
ABSTRACT

ABSTRACT
Objective To study the phonological characteristics and rehabilitation training methods of abnor-mal blade-alveolar consonants in children with functional articulation disorders(FAD).Methods A total of 150 children of 4 to 25 years old with blade-alveolar consonant articulation disorders were selected from 194 children di-agnosed with FAD as the research objects.The phonological characteristics of abnormal blade-alveolar consonants were analysed;30 children of 4 to 17 years old accepted speech therapy,exhaling training and functional treatment of blade-alveolar consonants (/d/,/t/,/n/,/l/).Patients were given speech assessments in the first and last training by using computer speech lab.Results The occurrence rate of abnormal blade-alveolar consonant was 77.32%(150/194);the error rate of/l/was 82.0% which was the highest;/d/was mainly substituted by/j/,and/t/was mainly substituted by/q/,/d/.Both/l/and/n/mainly showed omission.Males accounted for 82.35%(98/119) and females accounted for 80.65%(25/31)among substitution cases.Males accounted for 80.67%(96/119)and fe-males for 90.32%(28/31)among omission cases.The number of incorrect words decreased to (6.30±2.72)after speech training from(50.60±9.04)before speech training was established.The differences were statistically signifi-cant(Z= -4.875,P<0.05).The number of erroneous words was negatively correlated with age (r= -0.736,P<0.01).Conclusion Blade-alveolar consonant articulation disorders occur mainly on/d/,/t/,/l/,and the main erro-neous articulation patterns are substitution and omission.The training scheme and training methods established in this study are significantly effective.
ABSTRACT
@#Objective To explore the phonological characteristics of lateral misarticulation in children with functional articulation disor-ders and the rehabilitation approaches for them. Methods From June, 2013 to December, 2014, 44 children with lateral misarticulation were assessed and the phonological characteristics of lateral misarticulation were analyzed. They accepted targeted rehabilitation training. The cor-relation was analyzed between lateral misarticulation and age as well as severity of disorder. Results The frequency of lateral misarticulation was the most in Blade-palatals (75.00%), and then the dentals (65.91%), lingua-palatals (56.82%) and blade-alveolar consonant (20.45%). Thirty-eight cases were cured and 4 cases improved after 1 to 5 courses of rehabilitation. The overall cure rate was 86.36%(38/44), and it was 100%(11/11), 86.67%(13/15), 77.78%(14/18) in those with mild, moderate and severe disorder, respectively. There was no significant correlation between lateral misarticulation and age (r=0.100, P=0.752) as well as severity (r=0.257, P=0.092). Conclusion Lateral misarticu-lation in children with functional articulation disorders mainly occurs on blade-palatals, dentals and lingua-palatals. The targeted speech re-habilitation training is beneficial.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the phonological characteristics and rehabilitation training of abnormal velar in patients with functional articulation disorders (FAD).</p><p><b>METHODS</b>Eighty-seven patients with FAD were observed of the phonological characteristics of velar. Seventy-two patients with abnormal velar accepted speech training. The correlation and simple linear regression analysis were carried out on abnormal velar articulation and age.</p><p><b>RESULTS</b>The articulation disorder of /g/ mainly showed replacement by /d/, /b/ or omission. /k/ mainly showed replacement by /d/, /t/, /g/, /p/, /b/. /h/ mainly showed replacement by /g/, /f/, /p/, /b/ or omission. The common erroneous articulation forms of /g/, /k/, /h/ were fronting of tongue and replacement by bilabial consonants. When velar combined with vowels contained /a/ and /e/, the main error was fronting of tongue. When velar combined with vowels contained /u/, the errors trended to be replacement by bilabial consonants. After 3 to 10 times of speech training, the number of erroneous words decreased to (6.24±2.61) from (40.28±6.08) before the speech training was established, the difference was statistically significant (Z=-7.379, P=0.000).

@#Objective To explore the clinical characteristics and rehabilitation training of abnormal lateral consonant, namely/l/, of pa-tients with functional articulation disorders (FAD). Methods 107 patients with FAD were observed of the clinical characteristics of/l/. 30 pa-tients with/l/articulation disorder accepted speech training. The correlation and simple linear regression analysis were carried out on/l/ar-ticulation disorders and age. Results The articulation disorder of/l/ mainly showed replacement for/n/,/y/,/r/,/d/ or omission. When/l/combined with vowels contained/i/and/ü/, the main error was omission. When/l/combined with vowels contained/a/,/o/,/e/or/u/, the er-rors trended to be replacement rather than omission. After speech training, the patients made less mistakes about/l/(P<0.001). The frequen-cy of/l/articulation disorders was negatively correlated with age (r=-0.840). The result of simple linear regression analysis showed that the determination coefficient was 0.422. Conclusion The/l/articulation disorder mainly shows replacement or omission, varied with the vow-els. The targeted rehabilitation training may be helpful. Age plays an important role in the outcome of/l/articulation disorder.
