RESUMEN

Purpose This study investigated phonological and speech motor neural networks in children with residual speech sound disorder (RSSD) during an overt Syllable Repetition Task (SRT). Method Sixteen children with RSSD with /ɹ/ errors (6F [female]; ages 8;0-12;6 [years;months]) and 16 children with typically developing speech (TD; 8F; ages 8;5-13;7) completed a functional magnetic resonance imaging experiment. Children performed the SRT ("SRT-Early Sounds") with the phonemes /b, d, m, n, ɑ/ and an adapted version ("SRT-Late Sounds") with the phonemes /ɹ, s, l, tʃ, ɑ/. We compared the functional activation and transcribed production accuracy of the RSSD and TD groups during both conditions. Expected errors were not scored as inaccurate. Results No between-group or within-group differences in repetition accuracy were found on the SRT-Early Sounds or SRT-Late Sounds tasks at any syllable sequence length. On a first-level analysis of the tasks, the TD group showed expected patterns of activation for both the SRT-Early Sounds and SRT-Late Sounds, including activation in the left primary motor cortex, left premotor cortex, bilateral anterior cingulate, bilateral primary auditory cortex, bilateral superior temporal gyrus, and bilateral insula. The RSSD group showed similar activation when correcting for multiple comparisons. In further exploratory analyses, we observed the following subthreshold patterns: (a) On the SRT-Early Sounds, greater activation was found in the left premotor cortex for the RSSD group, while greater activation was found in the left cerebellum for the TD group; (b) on the SRT-Late Sounds, a small area of greater activation was found in the right cerebellum for the RSSD group. No within-group functional differences were observed (SRT-Early Sounds vs. SRT-Late Sounds) for either group. Conclusions Performance was similar between groups, and likewise, we found that functional activation did not differ. Observed functional differences in previous studies may reflect differences in task performance, rather than fundamental differences in neural mechanisms for syllable repetition.

RESUMEN

BACKGROUND: To determine best practices, surgeons who perform cleft palate surgery or surgery for velopharyngeal insufficiency need to be able to compare their outcomes in normalizing the velopharyngeal valve. METHODS: We conducted a comprehensive review of articles that reported speech/resonance outcomes following palatoplasty or surgery for velopharyngeal insufficiency. We analyzed protocols that were used and how the results were reported. We found 170 articles, published between 1990 and 2014, that met our inclusion criteria. RESULTS: Most studies (66%) had a sample size of <50 subjects, were retrospective (67%), were not blinded (83%), and did not report the use of reliability (68%). Most studies included 1 evaluator (27%) or 2 evaluators (30%). Only 80% of the articles specified that at least one speech pathologist was an evaluator. Most articles (56%) did not specify the speech samples used, and 65% used an informal test or did not specify the type of test used. Most studies used a perceptual rating scale for articulation (75%) and resonance (83%). Only 39% of the studies included an evaluation of velopharyngeal function. Finally, objective measures were used in only 28% of the studies (9% used aerodynamic measures and 19% used nasometry). CONCLUSIONS: Because these articles showed significant variability in how speech/resonance is evaluated and how the outcomes are reported, it is virtually impossible to compare results to determine best surgical procedures. Suggestions are given to standardize outcome measures to improve comparability of data.

RESUMEN

UNLABELLED: Children with persistent speech disorders (PSD) often present with overt or subtle motor deficits; the possibility that speech disorders and motor deficits could arise from a shared neurological base is currently unknown. Functional MRI (fMRI) was used to examine the brain networks supporting fine motor praxis in children with PSD and without clinically identified fine motor deficits. METHODS: This case-control study included 12 children with PSD (mean age 7.42 years, four female) and 12 controls (mean age 7.44 years, four female). Children completed behavioral evaluations using standardized motor assessments and parent reported functional measures. During fMRI scanning, participants completed a cued finger tapping task contrasted passive listening. A general linear model approach identified brain regions associated with finger tapping in each group and regions that differed between groups. The relationship between regional fMRI activation and fine motor skill was assessed using a regression analysis. RESULTS: Children with PSD had significantly poorer results for rapid speech production and fine motor praxis skills, but did not differ on classroom functional skills. Functional MRI results showed that children with PSD had significantly more activation in the cerebellum during finger tapping. Positive correlations between performance on a fine motor praxis test and activation multiple cortical regions were noted for children with PSD but not for controls. CONCLUSIONS: Over-activation in the cerebellum during a motor task may reflect a subtle abnormality in the non-speech motor neural circuitry in children with PSD.

RESUMEN

PURPOSE: The purpose of the current study was to describe the current state of practice for writing Individualized Education Program (IEP) goals for children with speech sound disorders (SSDs). METHOD: IEP goals for 146 children receiving services for SSDs within public school systems across two states were coded for their dominant theoretical framework and overall quality. A dichotomous scheme was used for theoretical framework coding: cognitive-linguistic or sensory-motor. Goal quality was determined by examining 7 specific indicators outlined by an empirically tested rating tool. In total, 147 long-term and 490 short-term goals were coded. RESULTS: The results revealed no dominant theoretical framework for long-term goals, whereas short-term goals largely reflected a sensory-motor framework. In terms of quality, the majority of speech production goals were functional and generalizable in nature, but were not able to be easily targeted during common daily tasks or by other members of the IEP team. Short-term goals were consistently rated higher in quality domains when compared to long-term goals. CONCLUSIONS: The current state of practice for writing IEP goals for children with SSDs indicates that theoretical framework may be eclectic in nature and likely written to support the individual needs of children with speech sound disorders. Further investigation is warranted to determine the relations between goal quality and child outcomes. LEARNING OUTCOMES: (1) Identify two predominant theoretical frameworks and discuss how they apply to IEP goal writing. (2) Discuss quality indicators as they relate to IEP goals for children with speech sound disorders. (3) Discuss the relationship between long-term goals level of quality and related theoretical frameworks. (4) Identify the areas in which business-as-usual IEP goals exhibit strong quality.

RESUMEN

PURPOSE: Language develops at variable rates in young children, yet markers for different developmental trajectories, have not been identified. Production of fricatives in words may be one marker because they are later developing sounds and contribute to syntactic production. We examined whether children who produced fricatives in words by 18 months had better vocabulary and grammar scores at 18, 24, and 30 months than children who did not. METHOD: The expressive language skills of 37 toddlers who did and did not produce fricatives in words by 18 months of age were compared at 18, 24 and 30 months of age. RESULTS: Expressive vocabulary scores and the use of grammatical markers were significantly better for children who produced fricatives by 18 months than for those who did not. This effect was consistent across scores at 18, 24, and 30 months. The total number of consonants and total number of fricatives produced at 18 months did not significantly predict expressive vocabulary scores. CONCLUSIONS: Because the children who produced fricatives by 18 months demonstrated better expressive language skills than their peers who did not produce fricatives by 18 months, the early production of fricatives by toddlers may be a marker of a faster expressive language developmental trajectory. LEARNING OUTCOMES: Readers will: (1) describe the relationship between early phonological development and early expressive lexical development, (2) describe the role of perceptual and motor development in speech sound the acquisition, and (3) describe the potential relationship between the production of fricatives and expressive language development.

RESUMEN

Reduced oral intake is a known complication of bone marrow transplant (BMT) and may result in short-term tube feedings. Although most children return to typical eating habits, a subgroup of children requires intervention. The focus of the current investigation was to retrospectively identify the incidence and characteristics of feeding and swallowing disorders in pediatric patients during the first 100 days after BMT and to determine what factors contribute to feeding/swallowing disorders past the BMT acute phase (100+ d). The charts of 292 sequential patients undergoing BMT were reviewed. Seventy-two children (25%) were referred for feeding and/or swallowing intervention with a mean age of 78.6 months (SD=±63.4). Sixteen patients underwent instrumental evaluation with swallowing dysfunction identified in 50% (n=8) of the patients. Oral-motor dysfunction was reported in 33% (n=24) and feeding disorders occurred in 61% (n=44) of the patients referred for treatment. This single-institution review describes the impact of this interruption in the first 100 days after transplant on feeding and swallowing and determined what factors place a child at an increased risk for requiring tube feeding for 100+ days after transplant. The type of BMT, the use of a tube during the first 100 days, and the age were all significant predictors of requiring a tube when considered together for the individual patient. Children who do not require a tube in the first 100 days are significantly less likely to require one in future, approximately 85% less likely to require one whereas children receiving an autologous transplant are approximately 70% less likely to require a tube than children receiving an allogenic transplant. Providers should consider an intervention for younger children undergoing BMT to help maintain or facilitate the development of their feeding and swallowing skills. This may lead to improved feeding outcome in the pediatric BMT population.

RESUMEN

OBJECTIVE: To determine methods by which professionals serving cleft palate/craniofacial teams are evaluating velopharyngeal function and to ascertain what they consider as a successful speech outcome of surgery. DESIGN: A 12-question survey was developed for professionals involved in management of velopharyngeal dysfunction. PARTICIPANTS: The survey was distributed through E-mail lists for the American Cleft Palate-Craniofacial Association and Division 5 of the American Speech-Language-Hearing Association. Only speech-language pathologists and surgeons were asked to complete the survey. A total of 126 questionnaires were completed online. RESULTS: Standard speech evaluations include perceptual evaluation (99.2%), intraoral examination (96.8%), nasopharyngoscopy (59.3%), nasometry (28.9%), videofluoroscopy (19.2%), and aerodynamic measures (4.3%). Significant variation existed in the types and levels of perceptual rating scales. Pharyngeal flap (52.9%) is the most commonly performed procedure for velopharyngeal insufficiency, followed by sphincter pharyngoplasty (27.5%). Criteria for surgical success included normal speech (50.8%), acceptable speech (27.9%), and "improved" speech (8%). However, most respondents felt that success should be defined as normal speech (71.2%). Most respondents believed that surgical success should be determined by the team speech-language pathologist (81.5%); although, some felt success should be determined by the patient/family (17.7%). CONCLUSION: This survey shows considerable variability in the methods for evaluating and reporting speech outcomes following surgery. There is inconsistency in what is considered a successful surgical outcome, making comparison studies impossible. Most respondents thought that success should be defined as normal speech, but this is not happening in current practice.
