ABSTRACT
@#Objective To investigate phonological characteristics and rehabilitation training approaches of bilabial consonant articula-tion disorders in patients after repaired cleft palate. Methods From January, 2012 to January, 2016, 51 patients with velopharyngeal incom-petence (VPI) and 57 patients with velopharyngeal competence (VPC) after cleft palate repaire were enrolled. Their phonological character-istics of bilabial consonants articulation disorders were analyzed. They accepted specific rehabilitation training. The correlation between bila-bial consonants articulation disorders and age was analyzed. Results/b/ showed mainly weak pressure in both VPI and VPC patients,/p/showed mainly weak pressure in VPI patients,/p/was mainly substituted by/b/in VPC patients. 46 cases were cured and 2 cases improved in VPI patients after 1-6 weeks of rehabilitation, and the overall cure rate was 90.20%(46/51), and was respectively 100%(13/13), 93.74%(15/16), 77.27%(17/22) in those with mild, moderate and severe disorder. 53 cases were cured and 4 cases improved in VPC patients after 1-5 weeks of rehabilitation, the overall cure rate was 92.98%(53/57), and was respectively 100%(17/17), 90.48%(19/21), 89.47%(17/19) in those with mild, moderate and severe disorder. The number of incorrect words negatively correlated with age in VPC patient (r=-1.000, P<0.001). Conclusion Bilabial consonant articulation disorders occurs mainly on/b/and/p/in patients repaired cleft palate,/b/shows main-ly weak pressure,/p/shows mainly weak pressure and substitution. Specific speech rehabilitation training is significantly effective.
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
<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). The number of erroneous words was negatively correlated with age (r=-0.691, P=0.000). The result of simple linear regression analysis showed that the determination coefficient was 0.472.</p><p><b>CONCLUSIONS</b>The articulation disorder of velar mainly shows replacement, varies with the vowels. The targeted rehabilitation training hereby established is significantly effective. Age plays an important role in the outcome of velar.</p>

OBJECTIVE: The purpose of this study is to determine clinical and phonological characteristics of the patients with specific language impairment (SLI). METHOD: Subjects were 24 SLI patients without known mental retardation, cerebral palsy, epilepsy, hearing loss or structural brain lesion and 23 normal children. Developmental history, oropharyngeal abnormality, and brainstem auditory evoked potentials were obtained in SLI patients. Receptive language age and quotient were assessed by Peabody picture vocabulary test. Phonetic characteristics of subjects were analysed using Visi-Pitch(R) and computerized speech laboratory. RESULTS: In perceptual evaluation, 32.3% of SLI patients showed incomplete articulation pattern. The patterns of incomplete articulation were substitution, distortion, nasalization, and addition. The receptive language of SLI patients (0.89 +/- 0.28) was significantly lower than control group (1.16 +/- 0.18). In Visi-Pitch(R) analysis, diadochokinetic rate and maximal phonation time were decreased in SLI patients. The total duration of three syllables in SLI patients were significantly prolonged, especially for bilabial heavily asperated and glottalized consonants and alveolar and velar slightly asperated, heavily asperated, and glottalized consonants. CONCLUSION: The patients with SLI showed characteristic defect in articulation as well as expressive and receptive language delayment. This articulatory defect may be resulted from disturbance of central programming and coordination of articulation. The objective and quantitative analysis of Phonological characteristics using computerized speech system in SLI patients can contribute to diagnose and evaluate the treatment outcome for the patients.
