Automatic landmark identification in cone-beam computed tomography.

OBJECTIVE: To present and validate an open-source fully automated landmark placement (ALICBCT) tool for cone-beam computed tomography scans. MATERIALS AND METHODS: One hundred and forty-three large and medium field of view cone-beam computed tomography (CBCT) were used to train and test a novel approach, called ALICBCT that reformulates landmark detection as a classification problem through a virtual agent placed inside volumetric images. The landmark agents were trained to navigate in a multi-scale volumetric space to reach the estimated landmark position. The agent movements decision relies on a combination of DenseNet feature network and fully connected layers. For each CBCT, 32 ground truth landmark positions were identified by 2 clinician experts. After validation of the 32 landmarks, new models were trained to identify a total of 119 landmarks that are commonly used in clinical studies for the quantification of changes in bone morphology and tooth position. RESULTS: Our method achieved a high accuracy with an average of 1.54 ± 0.87 mm error for the 32 landmark positions with rare failures, taking an average of 4.2 second computation time to identify each landmark in one large 3D-CBCT scan using a conventional GPU. CONCLUSION: The ALICBCT algorithm is a robust automatic identification tool that has been deployed for clinical and research use as an extension in the 3D Slicer platform allowing continuous updates for increased precision.

Three-dimensional Evaluation of the Carriere Motion 3D Appliance in the treatment of Class II malocclusion.

INTRODUCTION: This study aimed to quantify the outcomes of adolescent patients with Class II malocclusion treated with the Carriere Motion 3D Appliance (CMA) combined with full fixed appliances. METHODS: Cone-beam computed tomography scans of 22 patients were available before orthodontic treatment (T1), at removal of the CMA (T2), and posttreatment (T3). The average age of the patients was 13.5 ± 1.6 years at T1, 14.1 ± 0.2 years at T2, and 15.6 ± 0.5 years at T3. The 3-dimensional image analysis procedures were performed using ITK-SNAP (version 3.6.0; www.itksnap.org, Hatfield, Pa) and SlicerCMF (version 4.11.0; http://www.slicer.org, Cambridge, Mass); skeletal and dentoalveolar changes relative to cranial base, maxillary, and mandibular regional superimpositions were evaluated. RESULTS: Changes were analyzed with 1 sample t tests using the mean differences during the CMA phase (T1 to T2) and total treatment time (T1 to T3). Significant skeletal changes included a slight reduction of ANB from T1 to T3, mandibular growth (Co-Gn increment of 1.2 mm and 3.3 mm from T1 to T2 and T1 to T3, respectively), inferior displacement of point A, and anterior and inferior displacement of point B. The mandibular plane did not change significantly during treatment. During the CMA treatment, posterior tipping and distal rotation of the maxillary molars, tip back and inferior displacement of the maxillary canines, significant mesial rotation, and superior displacement of the mandibular molars were observed. These movements rebounded during the full fixed appliance phase except for the molar and canine vertical displacements. Clinically significant dental changes during treatment included a reduction in overjet and overbite, Class II correction of the molar and canine relationship, and proclination of the mandibular incisors. CONCLUSIONS: The CMA is an effective treatment modality for Class II correction in growing patients because of a combination of mesial movement of the mandibular molar, distal rotation of the maxillary molar, and anterior displacement of the mandible.

Nurse perspectives on supporting children and youth who use augmentative and alternative communication (AAC) in the pediatric intensive care unit.

Many children who require hospitalization in the pediatric intensive care unit (ICU) are unable to or have difficulty communicating through speech, whether because of preexisting or acute conditions. Children who are unable to be heard and understood using only speech benefit from aided augmentative and alternative communication (AAC), including in hospital settings. This qualitative interview study sought to understand the perspectives of nurses on care and support for children who use or would benefit from aided AAC in the pediatric ICU. Participants were six nurses who worked in pediatric intensive care at a tertiary care unit of a children's hospital in the United States. Three main themes were identified related to nurses' views about supporting children's communication: (a) Caring for the Whole Child, (b) Needing Support from Others and Moving between Roles, and (c) Working with Available Resources and Demands. Nurses emphasized the importance of a holistic approach to care, the impact of others' support and knowledge, and a desire for building greater capacity for promoting children's access to effective communication. Findings offer insight that could improve patient-centered care for children with complex communication needs and support for nurses themselves, particularly within the broader context of ICU liberation.

Augmentative and alternative communication services during the COVID-19 pandemic: impact on children, their families and service providers.

The closure of schools and healthcare facilities across the United States due to COVID-19 has dramatically changed the way that services are provided to children with disabilities. Little is known about how children who use augmentative and alternative communication (AAC), their families and their service providers have been impacted by these changes. This qualitative study sought to understand the perspectives of parents and speech-language pathologists (SLPs) on how COVID-19 has affected children, families, services providers and the delivery of AAC-related communication services. For the study, 25 parents and 25 SLPs of children who used aided AAC participated in semi-structured interviews, with data analyzed using qualitative thematic analysis. Parents and SLPs highlighted wide disparities in how children have been impacted, ranging from views of children making more progress with communication and language than before the pandemic to worries about regression. A complex system of factors and processes may explain these differences. COVID-19 will have lasting impacts on the lives of children with complex communication needs. This research highlights the crucial role of family-service provider partnerships and access to quality AAC services for children during the pandemic and into the future.

Engaging stakeholders to improve social validity: intervention priorities for students with complex communication needs.

Many factors impact intervention implementation in everyday practice, including the social validity of these interventions. As a way of addressing social validity, this study aimed to understand the perspectives of multiple stakeholders of school-aged children and adolescents who use aided and unaided augmentative and alternative communication (AAC) on their key intervention priorities for these children. Semi-structured interviews were conducted with 19 parents and professionals, which included special education teachers, paraprofessionals, and speech-language pathologists (SLPs). Qualitative content analysis focused on (a) identifying a framework of intervention priorities for children with complex communication needs and (b) understanding stakeholders' underlying values and attitudes that influenced perceptions about these priorities. Participants shared many intervention priorities and several core values. These intervention priorities included approaches focused on improving children's intrinsic abilities (i.e., skills-focused) and on improving children's extrinsic supports and opportunities (i.e., environment-focused). However, participants often portrayed diverging attitudes about different aspects of intervention, particularly self-efficacy (e.g., persistence in the face of challenges; confidence about inclusive education) and perceptions of students (e.g., keeping high expectations). These findings have important implications for practice and future research related to how attention to social validity can help bridge the research-to-practice gap.

Views of Parents on Supporting Language and Literacy for Their Children With Complex Communication Needs.

PURPOSE: Understanding students' home literacy environments can help speech-language pathologists, teachers, and other educators partner with families to promote language and literacy learning. This study focused on gaining insight into the views of parents of elementary-age students with intellectual and developmental disabilities who had complex communication needs related to supporting children's language and literacy learning in the home. METHOD: This qualitative study was conducted during the COVID-19 pandemic, when many schools were utilizing remote or hybrid learning arrangements. Participants were 37 parents of students with complex communication needs in kindergarten to fourth grade. Most children had either autism or Down syndrome, and they ranged from primarily communicating prelinguistically (e.g., gestures and nonword vocalizations) to using some two to three word phrases in different modes (e.g., speech, sign, and aided augmentative and alternative communication [AAC]). Each parent was interviewed three times over the 2020-2021 school year, and data were analyzed using an inductive qualitative approach. RESULTS: Findings showed patterns of commonalities and differences in parents' experiences, including related to their (a) goals and values about communication, language, and literacy; (b) perceptions and experiences with roles supporting language and literacy; and (c) satisfaction with supports and progress in these areas. CONCLUSION: This study provides important insight into the views of parents related to home literacy that can be used to improve the design and delivery of interventions for school-age students with complex communication needs and their families.

Examining the Family-Centeredness of Speech-Language Pathologists Working With Children Who Use Augmentative and Alternative Communication.

PURPOSE: Family-professional partnerships are important for youth learning to use aided augmentative and alternative communication (AAC). This study examined the family-oriented beliefs and practices of speech-language pathologists (SLPs) working with preschool and school-aged children learning to use aided AAC (aged 3-21 years), specifically during the COVID-19 pandemic. METHOD: Participants were 25 SLPs who participated in an individual semistructured interview. Qualitative analysis was used to identify and describe groups of SLPs based on commonalities and differences in their beliefs and practices working with families. The characteristics of SLPs in each group was also explored descriptively (e.g., race/ethnicity, work setting, caseload). RESULTS: SLPs clustered into three groups based on their beliefs and practices: (a) professionally centered, (b) family-allied, and (c) family-focused. SLPs varied across these groups in how they planned services, offered training/coaching, communicated, shared resources, offered emotional support, and adapted to and with different families. CONCLUSIONS: Findings indicate the need to support greater family-centeredness in AAC services by building on the strengths of SLPs in the field. Promoting strong family-professional partnerships could in turn improve outcomes for students who use AAC. SUPPLEMENTAL MATERIAL: https://doi.org/10.23641/asha.25044125.

Home Literacy Environment and Interventions for Children With Intellectual and Developmental Disabilities: A Scoping Review.

PURPOSE: The aim of this scoping review was to map the research literature published in English and in peer-reviewed journals related to the home literacy environment of children and youth aged 3-21 years with intellectual and developmental disabilities (IDD) who have significant support needs, including children with complex communication needs. METHOD: A systematic search was conducted in four databases, along with forward and backward searching. The search yielded 60 studies, which included intervention and nonintervention studies. Data were charted related to participant characteristics, study focus, intervention components, study design and methodological rigor, and study results. RESULTS: Findings provided insight into multiple dimensions of the home literacy environment for children with IDD, including the nature of parent views, practices, and interaction styles during shared reading. Findings also revealed gaps in the literature, specifically related to (a) limited representation of subgroups of children and youth with IDD, (b) limited representation of diverse families and caregivers, and (c) concerns about methodological quality. CONCLUSION: This review identifies important directions for future research and suggests ways to improve the design and delivery of home literacy interventions for children and youth with IDD and their families, including through family-centered and culturally responsive models.

Building Family Capacity: supporting multiple family members to implement aided Language modeling.

Family-centered capacity-building practices have been shown to benefit children and families. However, limited research explores these practices for children who use augmentative and alternative communication. This study explored an intervention to teach family members to implement an Aided Language Modeling (ALM) strategy across natural activities at home. A single case multiple probe design was used to evaluate the intervention with five family members and a girl with autism. Results showed the intervention increased family members' percentage of high-fidelity ALM strategy use and rate of ALM. Descriptively, a modest increase was also observed in the proportion of the child's communication using the speech-generating device. Social validity interviews suggested the goals, procedures, and outcomes were socially valid and supported family capacity building.

Views of Speech-Language Pathologists on Telepractice for Children Who Use Augmentative and Alternative Communication.

Telepractice has become increasingly utilized in disability services, particularly with recent and ongoing measures to slow the spread of the novel coronavirus (COVID-19). In this study, 361 speech-language pathologists (SLPs) responded to a national, web-based survey about their views on utilizing telepractice with children aged 3 to 21 who used aided augmentative and alternative communication (AAC), such as picture symbols or speech-generating devices. The views of SLPs varied, and SLPs who received training on AAC telepractice within the last 12 months had more positive views about telepractice than those who did not. Several factors were associated with when and how SLPs thought telepractice was beneficial to serve children who use aided AAC, including SLPs' foundational perspectives about telepractice, service delivery options, considerations related to the child and family, and broader resources and constraints.

Diet Outcomes from a Randomized Controlled Trial Assessing a Parenting Intervention Simultaneously Targeting Healthy Eating and Substance Use Prevention among Hispanic Middle-School Adolescents.

Parents play a significant role in adolescent health behaviors; however, few nutrition interventions for Hispanic adolescents involve parents. This study assessed the effects of a 10-week parenting intervention simultaneously targeting nutrition and substance use prevention. Hispanic parent/6th-8th-grade adolescent dyads (n = 239) were randomized to Families Preparing the New Generation Plus (FPNG+; nutrition/substance use prevention), FPNG (substance use prevention only), or Realizing the American Dream (RAD; academic success control). Surveys assessed diet, alcohol use, substance use intentions, and substance use norms at baseline (T1), immediately post-intervention (T2), and at 16 weeks post-intervention (T3). Latent change modeling assessed diet changes; adolescent substance use outcomes were assessed using effect sizes. Among adolescents, those in FPNG+ increased fruit (+0.32 cup equivalents, p = 0.022) and fiber intake (+1.06 g, p = 0.048) and did not change added sugars intake at T2; those in FPNG and RAD reduced their intake of fruit and fiber (p < 0.05 for both). FPNG+ parents marginally increased fruit/vegetable intake (+0.17 cup equivalents, p = 0.054) and increased whole grains intake (+0.25-ounce equivalents, p < 0.05), in contrast to the reduction among RAD and FPNG parents (p < 0.05). Reductions in added sugar intake at T2 were greater among FPNG and FPNG+ parents relative to RAD parents (p < 0.05). FPNG+ and FPNG had comparable substance use outcomes (i.e., both had lower alcohol use and intentions to use substances relative to RAD). Engaging parents in a nutrition and substance use prevention parenting intervention yielded positive changes in dietary intake and maintained substance use prevention outcomes among their adolescent children.

Augmentative and Alternative Communication Services During the COVID-19 Pandemic: Contextual Determinants of the Parent-Speech-Language Pathologist Partnership.

PURPOSE: The COVID-19 pandemic caused significant changes for family-professional interactions. Many services shifted to telepractice, with new opportunities for parents and speech-language pathologists (SLPs) to partner for service delivery. Parent-coached models of augmentative and alternative communication (AAC) intervention provide positive outcomes for children; however, SLPs have reported difficulty building strong partnerships with families. The shift to telepractice during the COVID-19 pandemic provided a unique context to examine factors influencing parent-SLP partnerships, particularly for parents with children who use aided AAC. METHOD: Twenty-five parents and 25 SLPs who engaged in services with children and youth from 3 to 21 years of age who used aided AAC during the initial stages of the COVID-19 pandemic in June 2020 participated. Semistructured interviews were conducted individually with parents and SLPs to understand perspectives on whether the change in service delivery facilitated or hindered family-oriented practice. Inductive qualitative analysis was used to analyze information about the factors impacting parent-SLP partnerships. RESULTS: The parent-SLP partnership was influenced by setting and systemic determinants, and intrinsic determinants to the parent and the SLP that included their history and rapport, beliefs about partnering, and knowledge and skills. These determinants served as barriers or facilitators to their partnership. CONCLUSIONS: It is essential to consider the relationship, expectations, and knowledge and skills that SLPs and parents bring to the partnership, along with extrinsic structural factors that can impact this partnership. Positive rapport, valued partnership, and an openness to sharing knowledge through teaming and collaboration provided for positive parent-SLP partnerships.

Graphing the Intersection of Rate and Fidelity in Single-Case Research.

Single-case research is a prevalent and useful method for evaluating the effects of interventions in special education research. A single-case graph "should make available all of the data that permit evaluation of the criteria for visual inspection, at the very least," while not misleading inspectors (Kazdin, 2011, p. 335). Although this is widely known, it poses challenges for multifaceted dependent variables, such as those that address both rate and a measure of quality, such as fidelity. Both factors may be important to accurately interpret intervention effects, such as those within cascading interventions implemented by natural change agents. However, representing both in a single graph is challenging. In response to this challenge, we present a single data set from a multiple-baseline design graphed in six distinct formats. Across these graphs, we discuss implications for visual analysis and interpretation and invite discussion of this important area of single-case research in search of recommendations for best practice.

Preparedness, Training, and Support for Augmentative and Alternative Communication Telepractice During the COVID-19 Pandemic.

PURPOSE: The global COVID-19 pandemic brought about widespread use of telepractice to provide services to children with communication disorders, including students who use aided augmentative and alternative communication (AAC) such as speech-generating devices. This descriptive quantitative study utilized network analysis to investigate the nature of speech-language pathologists' (SLPs') professional resource networks during the pandemic, including what aspects of their professional networks were associated with their confidence to use telepractice to serve students who use aided AAC and whether there were differences for school-based compared to nonschool-based SLPs. METHOD: Participants were 283 SLPs who responded to an online survey that consisted of closed- and open-ended survey items. A resource generator approach was used to gather data about SLPs' professional resource networks for AAC telepractice. RESULTS: SLPs varied widely in their confidence for AAC telepractice. School-based SLPs and SLPs who had 3 years or fewer of AAC experience reported lower confidence, whereas SLPs who spent more work time each week using telepractice and who accessed a greater number of different types of training reported higher confidence. The number of people in different roles providing personal support and the number of different electronic/print resources accessed were not significant predictors of SLPs' confidence. The majority of SLPs wanted additional training, support, or resources related to AAC telepractice. CONCLUSION: The findings from this research suggest the importance of SLPs' access to quality training and support in the areas of AAC and telepractice, particularly for school-based SLPs.

Augmentative and Alternative Communication Telepractice During the COVID-19 Pandemic: A National Survey of Speech-Language Pathologists.

PURPOSE: The novel coronavirus (COVID-19) pandemic has led to sudden, widespread use of telepractice, including providing services to children who use aided augmentative and alternative communication (AAC). This exploratory study examined speech-language pathologists' (SLPs) experiences using telepractice to provide services to children and youth aged 3-21 years who used aided AAC during the earlier months of the pandemic (May-June 2020). METHOD: Three hundred thirty-one SLPs responded to an online survey. Closed- and open-ended survey items were analyzed quantitatively and qualitatively and mixed at the point of interpretation to understand the experiences of SLPs related to the use of telepractice with children who use aided AAC, including how they perceived effectiveness. RESULTS: Most SLPs were using telepractice to provide both direct and consultation/coaching services to children who used aided AAC. There was fairly wide variation in perceptions of effectiveness of both types of services, but SLPs were more likely to rate consultation/coaching services as being more effective than direct services. SLPs identified factors impacting effectiveness across five dimensions: broader factors, practice-based factors (i.e., technology, the type of services), the child, parents and family members, and professionals. School-based SLPs perceived telepractice as being less effective than non-school-based SLPs. CONCLUSIONS: The use of telepractice during the COVID-19 pandemic has unfolded quite differently for different SLPs and the children who use aided AAC that they serve. Although AAC telepractice offers promise for the future, particularly for partnering with families, further research is needed to know how to overcome challenges experienced by SLPs.

The Effects of Telepractice to Support Family Members in Modeling a Speech-Generating Device in the Home.

Purpose Family members are an integral support for children with complex communication needs (CCN). However, there is limited research exploring "whole family" intervention to support children with CCN, including evidence-based approaches such as aided language modeling and innovative delivery options such as telepractice. The purpose of this study was to explore whether the use of telepractice-based training and coaching is a valid means of delivering intervention to the whole family unit to implement aided language modeling. Method A 4-year-old child with CCN who uses a speech-generating device and her four family members participated in the study. A single-case multiple-probe design across the four dyads was used to determine the effect of the memory aid, namely, Prepare, Show, Wait, and Respond, via telepractice intervention to teach family members to provide aided language modeling with fidelity during natural routines. Results We found that telepractice-based training and coaching increased family members' high-fidelity models and rate of modeling. The target child also showed an increase in independent communication and rate of augmentative and alternative communication use. Social validity interviews indicated that the participants found the intervention to be socially valid. Conclusions Given the findings of this study, speech-language pathologists should encourage the involvement of the whole family in augmentative and alternative communication interventions. Future research should examine the impact of training and coaching all family members together in their natural environment, explore specific adaptations for participants, and investigate the effects of intervention delivered by speech-language pathologists who work directly with families and utilize family-centered practices.

A Scoping Review of the Involvement of Children's Communication Partners in Aided Augmentative and Alternative Communication Modeling Interventions.

Purpose The purpose of this study was to inform practice and research by identifying and synthesizing research on interventions in which natural communication partners implemented aided augmentative and alternative communication (AAC) modeling strategies. Method A scoping review yielded 29 studies. Data were charted related to participant characteristics, intervention characteristics, partner instruction and assessment, and partner perspectives of social validity. Results More than 157 peer and 100 adult communication partners (e.g., parents, special educators, paraprofessionals) implemented aided AAC modeling strategies within included studies. To teach communication partners intervention strategies, researchers frequently reported using (a) oral instruction, (b) modeling, and (c) practice or application opportunities with performance feedback. Partner instruction frequently involved both training and concurrent support (e.g., coaching, facilitation, consultation, follow-up support). Conclusion Findings from this review inform the design and delivery of aided AAC modeling interventions by children's natural communication partners. Findings also highlight important avenues for enhancing the rigor of future research on interventions involving aided AAC modeling, including the quality of reporting and application of principles from implementation science.

Systematic Review of Interventions Involving Aided AAC Modeling for Children With Complex Communication Needs.

Building the communicative competence of individuals who use augmentative and alternative communication (AAC) requires intervention and support. This systematic review examined experimental studies involving aided AAC modeling to promote the expressive communication of children and youth (i.e., birth to age 21) with complex communication needs. A search yielded 48 studies involving 267 participants. Interventions were categorized according to three different approaches to aided AAC modeling-augmented input, models as prompts, and models within instructional demonstrations. Although the procedures varied, interventions were generally effective at improving diverse measures of expressive communication. This review provides insight for both researchers and practitioners by describing interventions involving three distinct approaches to aided AAC modeling, highlighting areas needing future research, and offering implications for practice.
