The PraxiFala Battery: A diagnostic accuracy study.

PURPOSE: To present the sensitivity and specificity and establish cutoff points (receiver operating characteristic [ROC] curve) for the PraxiFala Battery. METHOD: The sample included 308 Brazilian-speaking children aged 3;0-7;11. Twenty-one children had motor speech disorders (MSD), 58 children had phonological disorder (PD), and 229 had typical speech (TS) development. Participants were administered the PraxiFala Battery, which contains verbal (word and sentence production), nonverbal (orofacial praxis), and diadochokinetic tasks. The sensitivity and specificity of items in each task were then calculated using ROC curves. RESULT: Total scores on the verbal (word production), nonverbal (orofacial praxis), and diadochokinetic tasks had good sensitivity and specificity. The only scores with poor sensitivity and specificity in differentiating between TS, PD, and MSD were consistency and prosody in the verbal tasks (sentence production), and item /ta/ in the diadochokinetic task. Area under the ROC curve (AUC) values were greater than 0.7 for most items in the comparison between TS vs. MSD and PD vs. MSD. AUC values were poor or fair among children with TS and PD, suggesting that this instrument may not be accurate in identifying these groups. CONCLUSION: The verbal, nonverbal, and diadochokinetic tasks in the PraxiFala Battery had good sensitivity and specificity.

Performance in the accuracy task in children with Childhood Apraxia of Speech after an integrated intervention of literacy and motor skills.

Difficult in literacy skills are often seen in children with Childhood Apraxia of Speech (CAS). This occurs because oral language has direct relationship with reading and writing learning. The purpose of this study was to evaluate the performance in the accuracy task of an integrated phonoarticulatory awareness, motor skills and literacy intervention of three children with CAS. Three boys between 5;3 and 5;8 years of age, with CAS, were offered 2 hours per week of therapy sessions based on literacy and motor skills. The children were assessed before and after therapy and at a maintenance assessment 1 month after the treatment ceased. The children improved on the accuracy task considering their deficits level. Improvement was maintained at the maintenance assessment. Therapy based on literacy considering phonoarticulatory awareness and motor skills can help children with CAS, but the severity of the children's communication problems must be taken into consideration.

RESUMO Dificuldade nas habilidades de alfabetização são frequentemente observadas em crianças com Apraxia da Fala na Infância (AFI). Isso ocorre porque a linguagem oral tem relação direta com a aprendizagem da leitura e da escrita. O objetivo deste estudo foi avaliar o desempenho na tarefa de acurácia de uma intervenção integrada de consciência fonoarticulatória, habilidades motoras e letramento de três crianças com AFI. Três meninos com idade entre 5:3 e 5:8 anos, com AFI, receberam 2 horas semanais de sessões de terapia baseadas na alfabetização e habilidades motoras. As crianças foram avaliadas antes e após a terapia e em uma avaliação de manutenção 1 mês após o término do tratamento. As crianças melhoraram na tarefa de precisão, considerando o nível de seus déficits. A melhora foi mantida na avaliação de manutenção. A terapia baseada na alfabetização, considerando a consciência fonológica e as habilidades motoras, pode ajudar as crianças com AFI, mas a gravidade dos problemas de comunicação das crianças deve ser levada em consideração.

Dynamic Evaluation of Motor Speech Skill: Adaptation for Brazilian Portuguese.

PURPOSE: To describe the adaptation of verbal tasks (words) in the Dynamic Evaluation of Motor Speech Skills - DEMSS (Strand et al., 2013; Strand & McCauley, 2019) for subsequent inclusion in an analogous instrument in Brazilian Portuguese (BP). METHODS: The adaptation process consisted of six steps. Step 1: Three professionals carried out the translation and back-translation of the test's instructions and background content. Step 2: Two speech-language pathologists (SLP) with expertise in speech-language selected new stimuli for the instrument to make it appropriate for BP. Step 3: Seven expert judges determined the adequacy of test stimuli. Step 4: Eight non-expert judges, children with typical speech development, indicated whether the stimulus words were part of their vocabulary. Step 5: the instrument was administered in 20 children with typical speech development (pilot sample). The results of steps 3, 4 and 5 were examined using Content Validity Ratio. Step 6: Administration of the BP version of the DEMSS in one case of Childhood Apraxia Speech (CAS). RESULTS: 269 words were selected by the expert SLP (Step 2). These words were submitted to evaluation for expert judges (Step 3) and 96 of them were considered adequate. These items were then submitted to the child judges (Step 4) to evaluate their knowledge and use of the words, and in the pilot sample (Step 5) to evaluate the production accuracy of a larger group of children. A total of 44 words were selected after analysis of the results of Steps 4 and 5. In Step 6 the patient completed the final version of the BP version of the DEMSS to determine the feasibility of its use in young children with CAS. CONCLUSION: The translation, back-translation and evaluations by nativespeaking expert judges during the cross-cultural adaptation process and the application in one children with CAS demonstrate the content validity of the adapted instrument. Then, the BP version of the DEMSS has adequate content validity for the assessment of motor speech skills.

Phonological Assessment Instrument (INFONO): A pilot study. / Instrumento de Avaliação Fonológica (INFONO): estudo piloto.

PURPOSE: To analyze the recognizability and effectiveness of items in the Phonological Assessment Tool (Instrumento de Avaliação Fonológica - INFONO) at eliciting target words, as well as to evaluate the internal consistency of the instrument and compare performance between genders, school types and typical vs. atypical phonological development. METHOD: Participants were 48 children (n=26 with typical phonological development and n=22 with atypical development) categorized by age (6 age groups ranging from 3 years and 8 years 11 months), type of school (public vs. private) and gender (male vs. female). Data were collected by the spontaneous naming task of the INFONO. Recognition rates, scores, recognition difficulties and internal consistency were examined in 116 items. Performance in a final set of 84 items was also compared between genders, school types and typical/atypical phonological development. RESULTS: Most target words achieved high recognition rates were considered suitable for use in the INFONO. Some images had to be redesigned to facilitate the spontaneous production of target words, while other items were excluded from the instrument altogether. The instrument demonstrated excellent internal consistency. There were no statistically significant differences between genders and school types, though differences were observed between typically and atypically developing children. CONCLUSION: The images in the INFONO were successfully recognized by participants and were effective at eliciting the target words. The final set of items contained the minimum number of target words which would allow for an assessment of all phonemes in Brazilian Portuguese in different word and syllable positions, and these items presented excellent internal consistency.

Instrumento de Avaliação Fonológica (INFONO): estudo piloto / Phonological Assessment Instrument (INFONO): A pilot study

RESUMO Objetivo: Analisar a adequação dos itens propostos para o Instrumento de Avaliação Fonológica (INFONO) quanto ao reconhecimento e à produção da palavra-alvo, bem como analisar a consistência interna dos itens selecionados e comparar entre as variáveis sexo, tipo de escola e desenvolvimento fonológico (típico e atípico). Método: Participaram 48 crianças (n=26 com desenvolvimento fonológico típico e n=22 com desenvolvimento fonológico atípico) categorizadas por: idade (seis faixas etárias de 3 a 8 anos e 11 meses); tipo de escola (pública e privada), e sexo (feminino e masculino). Utilizou-se o INFONO por nomeação espontânea para a coleta dos dados da fala. Analisou-se o percentual de reconhecimento e produção dos itens (n=116), as dificuldades de reconhecimento destes, a consistência interna para o total de itens, e o desempenho das crianças (n=84), considerando as variáveis sexo, tipo de escola e desenvolvimento fonológico. Resultados: A maioria dos itens apresentou um percentual de reconhecimento alto, sendo estes considerados adequados para compor o INFONO. Algumas imagens precisaram ser reelaboradas para facilitar a produção espontânea do alvo e outras foram excluídas do instrumento. O instrumento demonstrou excelente consistência interna dos itens. Não houve diferença estatisticamente significante entre as variáveis sexo e tipo de escola, mas sim quanto ao desenvolvimento fonológico. Conclusão: O INFONO permitiu a correta identificação das imagens e a produção do alvo desejado. Ainda, obteve-se uma quantidade mínima de itens que possibilitam a avaliação de todos os fonemas do Português Brasileiro em diferentes posições na sílaba e na palavra, e esses itens apresentaram excelente consistência interna.

Analysis of the components of Frequency-Following Response in phonological disorders.

INTRODUCTION: When identifying the auditory performance of children with phonological disorders, researchers assume that this population has normal peripheral hearing. However, responses at more central levels might be atypical. OBJECTIVE: To investigate the effect of phonological disorders on Frequency-Following Responses (FFRs) in the time domain. METHODS: Participants were 60 subjects, aged 5 to 8:11 years, divided into two groups: a control group, composed of 30 subjects with normal language skills; and a study group composed of 30 subjects diagnosed with Phonological Disorder (PD). All subjects were tested for Frequency-Following Responses. RESULTS: In the group of children with PD there was an increase in the latency of all FFR components, with a significant statistical difference for components V (p = 0.015); A (<0.001); C (0.022); F (<0.001); and O (0.001). There was also a reduction in the Slope measure in the group with PD (p = 0.004). CONCLUSION: The FFR responses are altered in children with PD. This suggests that children with PD present a disorganization in the neural coding of complex sounds. This could compromise specially the development of linguistic/phonological abilities, which can reflect in daily communication.

Evidence of validity and reliability of a phonological assessment tool. / Evidências de validade e fidedignidade de um instrumento de avaliação fonológica.

PURPOSE: To present evidence of the validity and reliability of a phonological assessment tool developed to assess the phonological inventory of Brazilian Portuguese. METHODS: The study included 866 children aged between 3 and 8:11 years, divided into three groups: typical, control and clinical. Participants were evaluated using a phonological assessment software, which prompted the spontaneous naming of a series of images. The children's responses were audio recorded and transcribed at the time of the assessment, by the software itself. The Cronbach's alpha coefficient was used to evaluate the internal consistency of the instrument for reliability and validity purposes. Criterion validity was examined by comparing the performance of different groups using Student's t-test for independent samples. Intra- and inter-rater agreement were investigated using Kendall's tau. Results were considered significant at p ≤ 0.05. RESULTS: The present study provided evidence of validity and reliability (internal consistency) for this phonological assessment tool, confirming the reliability of its items and demonstrating excellent agreement rates between examiners regarding its scoring (intra- and inter-rater reliability). The criterion validity assessment demonstrated that the control group outperformed the clinical group across all phonemes, showing that test scores were successful in identifying children with speech sound disorders (phonological disorders). CONCLUSION: The present findings provide strong evidence of the validity and reliability of this phonological assessment tool.

OBJETIVO: Apresentar evidências de validade e fidedignidade de um instrumento de avaliação fonológica (INFONO) desenvolvido para avaliar os fonemas do Português Brasileiro. MÉTODO: Participaram do estudo 866 crianças com idades entre 3 e 8:11 anos, divididas em grupos: típico, controle e clínico. Os participantes foram avaliados pelo INFONO por nomeação espontânea. A produção da criança foi gravada e transcrita no momento da avaliação, no próprio software. Para análise de validade e fidedignidade, foram analisadas a consistência interna a partir da técnica Alpha de Cronbach. Para a validade de critério, comparou-se o desempenho entre os grupos através do teste t de Student para amostras independentes. A fidedignidade foi analisada pela concordância intra e interavaliadores por meio do Teste de Kendall. Considerou-se significância quando p ≤0,05. RESULTADOS: O INFONO apresentou evidências de validade e fidedignidade (consistência interna), indicando uma confiabilidade satisfatória dos itens, bem como excelente concordância entre os avaliadores em relação aos escores do teste (confiabilidade intra e interavaliador). Em relação à validade de critério, o desempenho do grupo clínico para todos os fonemas foi inferior ao grupo controle, mostrando que os escores são sensíveis para identificar crianças com desvio fonológico. CONCLUSÃO: O INFONO apresentou fortes evidências de validade e fidedignidade.

Purpose To compare performance between children with typical speech acquisition, phonological disorders, and childhood apraxia of speech for the variables overall articulatory accuracy and consistency of the Dynamic Evaluation of Motor Speech Skill - Brazilian Portuguese version (DEMSS-BR). Methods Study participants were 18 children of both genders aged 4 years and 6 months to 5 years and 8 months. The sample was divided into three groups: six children with typical speech acquisition (TSA), six children with phonological disorder (PD), and six individuals with childhood apraxia of speech (CAS). All participants were submitted to the DEMSS-BR and had their subscores of speech accuracy and consistency measured. Performance comparison between the groups was statistically evaluated using the Mann-Whitney U Test. Results Participants in the group with CAS presented poorer performance for the variables overall articulatory accuracy and consistency compared with those of participants in the other two groups. Conclusion The group of children with childhood apraxia of speech presented poorer performance on the DEMSS-BR compared with those of the groups with typical speech acquisition and phonological disorders. The study demonstrated that the DEMSS-BR assists with differential diagnosis of children with speech sound disorders.

Prevalence of phonological disorders and phonological processes in typical and atypical phonological development. / Ocorrência do desvio fonológico e de processos fonológicos em aquisição fonológica típica e atípica.

PURPOSE: To determine the occurrence of phonological disorders by age, gender and school type, and analyze the phonological processes observed in typical and atypical phonological development across different age groups. METHODS: The sample consisted of 866 children aged between 3:0 and 8:11 years, recruited from public and private schools in the city of Santa Maria/RS. A phonological evaluation was performed to analyze the operative phonological processes. RESULTS: 15.26% (n = 132) of the sample presented atypical phonological acquisition (phonological disorders). Phonological impairments were more frequent in public school students across all age groups. Phonological alterations were most frequent between ages 4 -to 6, and more prevalent in males than females in all but the youngest age group. The most common phonological processes in typical phonological acquisition were: cluster reduction; nonlateral liquid deletion in coda; nonlateral liquid substitution in onset; semivocalization of lateral liquids in coda; and unstressed syllable deletion. In children with phonological disorders, the most common phonological processes were: lateral and nonlateral liquid substitution in onset position; nonlateral liquid deletion; fronting of fricatives in onset position; unstressed syllable deletion; semivocalization of nonlateral liquid in coda; and nonlateral liquid deletion in coda position. CONCLUSION: Phonological processes were highly prevalent in the present sample, and occurred more often in boys than in girls. Information regarding the type and frequency of phonological processes in both typical phonological acquisition and phonological disorders may contribute to early diagnosis and increase the efficiency of treatment planning.

Factors Influencing Consonant Acquisition in Brazilian Portuguese-Speaking Children.

Purpose: We sought to provide valid and reliable data on the acquisition of consonant sounds in speakers of Brazilian Portuguese. Method: The sample comprised 733 typically developing monolingual speakers of Brazilian Portuguese (ages 3;0-8;11 [years;months]). The presence of surface speech error patterns, the revised percentage consonants correct, and the age of sound acquisition were evaluated using phonological assessment software. The normative values for these variables were reported using means and standard deviations. Results: Age had a significant impact on phoneme production. Increasing age was generally associated with an increase in correct phoneme production, a reduction in error patterns, and an increase in scores on revised percentage consonants correct. Phonological error patterns persisted for a longer time in consonants and consonant clusters acquired later in development. The 2 youngest age groups differed from the remainder of the sample on the frequency of the following phonological patterns: cluster reduction, liquid gliding, fricative deletion-coda, and weak-syllable deletion. Performance was similar between groups starting at 5;0 years old. Conclusion: This study confirmed that nasal and stop consonants are acquired first, followed by fricatives and, finally, liquids. We suggest that future studies replicate our investigation in larger samples and younger age groups.

Ocorrência do desvio fonológico e de processos fonológicos em aquisição fonológica típica e atípica / Prevalence of phonological disorders and phonological processes in typical and atypical phonological development

RESUMO Objetivo Determinar a ocorrência de desvio fonológico quanto à idade, gênero e tipo de escola, além de verificar e analisar os processos fonológicos em casos de aquisição fonológica típica e atípica em diferentes faixas etárias. Método Participaram 866 crianças com idades entre 3:0 e 8:11, matriculadas em escolas públicas e privadas de Santa Maria-RS. Realizou-se avaliação fonológica para analisar os processos fonológicos operantes. Resultados 15,26% (n = 132) das crianças avaliadas apresentavam aquisição fonológica atípica (desvio fonológico). As escolas públicas tiveram maior ocorrência de desvio fonológico para todas as idades pesquisadas. Houve maior ocorrência de desvio fonológico nas idades de 4 anos, 5 anos e 6 anos. O gênero masculino teve maior ocorrência que o feminino, com exceção na idade de 3 anos. Na aquisição fonológica típica, os processos que mais ocorreram foram: redução do encontro consonantal, apagamento de líquida não lateral em coda, substituição de líquida não lateral em onset, semivocalização de líquida não lateral em coda e apagamento de sílaba átona. No desvio fonológico, foram: substituição de líquida lateral e não lateral em onset, apagamento de líquida não lateral, anteriorização de fricativa em onset, apagamento de sílaba átona, semivocalização de líquida não lateral em coda e apagamento de líquida não lateral em coda. Conclusão A média da ocorrência foi considerada alta e mais frequente nos meninos. É importante saber a ocorrência e conhecer os processos fonológicos operantes na fala das crianças, pois estes podem auxiliar no diagnóstico precoce das alterações fonológicas, bem como na elaboração do planejamento terapêutico.

Tools for the assessment of childhood apraxia of speech.

PURPOSE: This study systematically reviews the literature on the main tools used to evaluate childhood apraxia of speech (CAS). RESEARCH STRATEGY: The search strategy includes Scopus, PubMed, and Embase databases. SELECTION CRITERIA: Empirical studies that used tools for assessing CAS were selected. DATA ANALYSIS: Articles were selected by two independent researchers. RESULTS: The search retrieved 695 articles, out of which 12 were included in the study. Five tools were identified: Verbal Motor Production Assessment for Children, Dynamic Evaluation of Motor Speech Skill, The Orofacial Praxis Test, Kaufman Speech Praxis Test for Children, and Madison Speech Assessment Protocol. There are few instruments available for CAS assessment and most of them are intended to assess praxis and/or orofacial movements, sequences of orofacial movements, articulation of syllables and phonemes, spontaneous speech, and prosody. CONCLUSION: There are some tests for assessment and diagnosis of CAS. However, few studies on this topic have been conducted at the national level, as well as protocols to assess and assist in an accurate diagnosis.

Orofacial Praxis Abilities in Children with Speech Disorders

Introduction Phonological development occurs in a gradual manner until the age of 7 years. The phonological system is constructed in a similar way for all children, despite presenting some variations in terms of age, paths taken, or repair strategies used. Objective To compare the orofacial praxis abilities of children with typical phonological development (DFT), children with phonetic-phonological impairment (DFoFe), and children with phonological impairment (DF), using two tests to assess the orofacial praxis abilities. Methods The sample consisted of 82 subjects between 4 and 8 years of age who attended public schools (from preschool to the second year of secondary school) in the city of SantaMaria, Brazil. Of these, 29 were diagnosed with DFT, 29 with DF, and 24 with DFoFe; much of this sample wasmale. Two tests of praxis abilities and assessment of the stomatognathic system were administered. Statistical analysis was performed using the chi-square test, with a significance level of 5%. Results Generally children with DFoFe underperformed in tests of praxis when compared with subjects with DF and DFT. Conclusion The results showed that children with DFoFe have more difficulty in orofacial praxis abilities than subjects in the other groups studied. This result could be expected, because subjects with DFoFe show changes in both phonetic and phonological levels of speech.(AU)

OBJETIVO: verificar, bem como relacionar entre si, o desempenho de crianças com Desvio Fonológico e com Desenvolvimento Fonológico Típico na avaliação do Sistema Estomatognático e em testes de habilidades práxicas orofaciais avaliando suas habilidades práxicas orofaciais. MÉTODOS: amostra constituiu-se de 50 sujeitos, com idades entre quatro e oito anos, com Desvio Fonológico e com Desenvolvimento Fonológico Típico. Avaliou-se a fonologia por meio do instrumento Avaliação Fonológica da Criança e a gravidade do desvio por meio do Percentual de Consoantes Corretas. Posteriormente, aplicou-se a Avaliação do sistema estomatongático e o The Orofacial Praxis Test, para avaliar as habilidades práxicas orofaciais. Os dados foram tabulados e submetidos a tratamento estatístico, considerando-se p<0,05. RESULTADOS: com relação ao sistema estomatongático, observou-se diferença estatística entre os grupos apenas nas tarefas de assobio, contração e vibração de lábios e de língua, apresentando desempenho inferior as crianças com Desvio Fonológico. O mesmo foi observado quanto à postura de língua na sucção. As médias obtidas nas tarefas de habilidades práxicas orofaciais realizadas após Imitação foram melhores que após Solicitação Verbal, para todas as idades. Ainda, as crianças com menor idade apresentaram mais alterações que as crianças maiores, da mesma forma que as crianças com Desvio Fonológico apresentaram mais dificuldades que aquelas sem alterações de fala. CONCLUSÃO: as crianças com Desvio Fonológico apresentaram mais alterações do sistema estomatognático e das habilidades práxicas orofaciais que aquelas com Desenvolvimento Fonológico Típico, havendo melhora no desempenho com o avanço da idade e encontrando-se estas alterações relacionadas com as alterações de fala. .

PURPOSE: to verify and correlate between each other, the performance of the children with Phonological Disorder and with Typical Phonological Development in the evaluation of the Stomatognathic System and in tests being evaluated yours orofacial praxis abilities. METHODS: the sample consisted of 50 children, of both genders, with ages between four and eight years, with Phonological Disorder and with Typical Phonological Development. It was realized the phonological evaluation through the instrument of the Phonological Evaluation of Children. Then, it has applied the Protocol of the Stomatognathic System and the protocol The Orofacial Praxis Test to evaluate the orofacial praxis abilities. The data had been tabulated and submitted the statistical treatment, considering p<0,05. RESULTS: with regard to Stomatognathic System, statistics difference between the groups was observed only whistles in it, contraction and vibration of lips and vibration of tongue, with lower performance of the children with Phonological Disorder. The same was observed to posture of tongue in the suction. The averages gotten in the praxis abilities tasks carried through after Imitation had been better that after Verbal Request, for all the ages. Still, the children with lower age had more alterations that the biggest, and also the children with Phonological Disorder had more difficulties that the children without speech alterations. CONCLUSION: the children with Phonological Disorder present more alterations of Stomatognathic System and the praxis abilities that those with Typical Phonological Development, with improvement of the same with the advance of the age and been relationship with the speech alterations. .

Relação entre os fonemas linguodentais e habilidades de mobilidade de língua / Relationship between linguodental phonemes and mobility of tongue / Relación entre fonemas linguodentales y habilidades de movilidad de la lengua

Introdução: o objetivo deste trabalho foi relacionar a produção dos fonemas linguodentais (/t/, /d/, /n/e /l/) e as habilidades de mobilidade de língua em 125 crianças de ambos os sexos e com idades entre 4:0 e 8:11. Método: a pesquisa foi realizada com base nos protocolos pertencentes a um banco de dados. Os pais e/ou responsáveis pelos sujeitos autorizaram a participação destes assinando o Termo de Consentimento Livre e Esclarecido. Tais sujeitos apresentavam diagnóstico prévio de desvio fonológico (DF) e alterações no sistema estomatognático (SEG), os resultados coletados foram do período pré-tratamento. A avaliação do sistema fonológico foi realizada através do instrumento Avaliação Fonológica da Criança (AFC) e a gravidade analisada através do cálculo do Percentual de Consoantes Corretas-Revisado (PCC-R). Assim, a amostra foi dividida em quatro grupos de segmentos (/t/, /d/, /n/ e /l/) subdivididos em três subgrupos: fonema adquirido, parcialmente adquirido e ausentes. Na avaliação do SEG foi verificado, entre diversos aspectos, as alterações de mobilidade de língua relevantes para este trabalho. A análise estatística foi realizada através do teste Mann-Whitney (teste U) no programa Statística 9.1 (significância estatística de 5%). Resultados: observou-se a inexistência de relação estatística entre os fonemas linguodentais e as habilidades de mobilidade de língua. Conclusão: este achado sugere que a produção dos fonemas /t/,/d/, /n/ e /l/ não está relacionada com as habilidades de movimento de língua.AU(AU)

Introduction: This research aimed at relating the production of linguodental phonemes (/t/, /d/, /n/ e /l/) to the abilities concerning the mobility of the tongue in 125 children, male and female, aged 4:0 to 8:11. Method: The research was based on protocols from a specific database. Parents and/or guardians responsible for the subjects have authorized their participation by signing free and clarified consent terms. The subjects presented diagnosis of phonological disorder (PD) and alteration only in the stomatognathic system (SS). The results are related to the period before treatment. The evaluation of the phonological system has been made through the means of Phonological Evaluation of Children (FEC) and the gravity was analyzed through the percentage of consonants correct ? Revised (PCC-R). Being so, the sample was divided into four main groups of segments (/t/, /d/, /n/ e /l/) subdivided in three groups: acquired, partially acquired and absent phoneme. In SS evaluation, alterations in the mobility of the tongue were verified, among many other aspects. A statistical analysis has been done through Mann-Whitney U test using Statística 9.0 program (5% in statistical significance). Results: it was possible to verify the nonexistence of statistical relation between the production of linguodental phonemes and the abilities concerning mobility of the tongue. Conclusion: these findings suggest that the production of the phonemes /t/, /d/, /n/ e /l/ and such abilities are not related.(AU)(AU)

Introducción: El objetivo de este trabajo fue relacionar la producción de fonemas linguodentales (/ t /, / d /, / n / y / l /) y habilidades de movilidad de la lengua, en 125 niños de ambos sexos con edades entre 4:0 y 08:11. Método: El estudio se realizo con base en protocolos que pertenecen a un banco de datos. Los padres y / o responsables por los sujetos autorizaron su participación firmando el Instrumento de Consentimiento Libre y Esclarecido. Los sujetos tenían un diagnóstico previo de trastorno fonológico (TD) y - cambios en el sistema estomatognático (SEG), los resultados recogidos fueron del período de pre-tratamiento. La evaluación del sistema fonológico se realizó por medio del instrumento Evaluación onológica del Niño (EFN) y la gravedad evaluada mediante el cálculo del Porcentaje de Consonantes Correcta-Revisado (PCC-R). Asi, la muestra se dividió en cuatro grupos de segmentos (/ t /, / d /, / n / e / l /) subdivididos en tres subgrupos: fonemas adquiridos, parcialmente adquiridos y ausentes. En la evaluación del SEG se observó, entre diversos aspectos, los cambios en la movilidad de la lengua relevantes para este trabajo. El análisis estadístico se realizó mediante la prueba de Mann-Whitney (U) en el programa Statistica 9.1 (significación estadística de 5%).Resultados: No hubo relación estadísticamente significativa entre los fonemas linguodentais y las habilidades de movilidad de la lengua. Conclusión: Estos hallazgos sugieren que la producción de los fonemas / t /, / d /, / n / y / l / no está relacionada con las habilidades de movimiento de la lengua.(AU)(AU)
