"Everyone screens to some extent": Barriers and facilitators of developmental screening among children with sickle cell disease: A mixed methods study.

BACKGROUND: Developmental delays are common among children with sickle cell disease (SCD). Existing guidelines support consistent screening to increase the identification of deficits and support referral to rehabilitative interventions, yet adherence remains variable. This study sought to assess current practices and identify barriers and facilitators to improve developmental screening for children 0-3 years with SCD. PROCEDURE: A mixed methods approach, guided by the Exploration and Preparation stages of the Exploration, Preparation, Implementation, and Sustainment (EPIS) framework, assessed developmental screening practices among primary care providers and hematologists. Phase 1 included the SCD Developmental Surveillance and Screening Guideline and Practice Survey. Phase 2 included the SCD Developmental Screening Organizational Survey alongside semi-structured interviews. Descriptive and qualitative methods summarized the findings. RESULTS: Thirty-three providers from general pediatrics and hematology completed phase 1. Use of standardized developmental screening measures was variable, with the most frequently used being the Modified Checklist for Autism in Toddlers (77%) and the Ages and Stages Questionnaire (55%). Fifteen providers participated in phase 2, and reported they were most likely to engage in changes to improve their practice (mean = 4.4/5) and least likely to support spiritual health and well-being (mean = 3.5/5). Three themes emerged:(i) developmental screening is not standardized or specific to SCD, (ii) children with SCD benefit from a multidisciplinary team, and (iii) healthcare system limitations are a barrier. CONCLUSIONS: Developmental screening is inconsistent and insufficient for young children with SCD. Providers are interested in supporting children with SCD, but report a lack of standardized measures and consistent guidance as barriers.

Cingulo-opercular control network and disused motor circuits joined in standby mode.

Whole-brain resting-state functional MRI (rs-fMRI) during 2 wk of upper-limb casting revealed that disused motor regions became more strongly connected to the cingulo-opercular network (CON), an executive control network that includes regions of the dorsal anterior cingulate cortex (dACC) and insula. Disuse-driven increases in functional connectivity (FC) were specific to the CON and somatomotor networks and did not involve any other networks, such as the salience, frontoparietal, or default mode networks. Censoring and modeling analyses showed that FC increases during casting were mediated by large, spontaneous activity pulses that appeared in the disused motor regions and CON control regions. During limb constraint, disused motor circuits appear to enter a standby mode characterized by spontaneous activity pulses and strengthened connectivity to CON executive control regions.

Individual-level behavioral interventions to support optimal development of children with sickle cell disease: A systematic review.

This review aimed to identify and describe individual-level behavioral interventions for children 0-18 years of age with sickle cell disease (SCD). PRISMA guidelines were followed at each stage of this review. Twenty-seven studies were included, representing six intervention types: disease knowledge (n = 7), self-management (n = 7), pain management (n = 4), school functioning (n = 4), cognitive health (n = 4), and mental health (n = 2). Most interventions targeted older children (5+ years), while only two examined interventions for children 0-3 years. This review suggests that offering education about disease knowledge, self-management, and pain management interventions can be beneficial for this population. Future research is needed to understand interventions to support young children and the impact of SCD on development.

Transforming Occupational Therapy for the 21st Century PAIRE: Recognize Privilege, Acknowledge Injustice, and Reframe Perspective to Reach Equity.

Theories, models, and frameworks provide the foundation for occupational therapy education, research, and clinical practice. While most have a systems approach focus, other factors, such as societal influences and structural inequities, also contribute to health. Using a cross-sectional design, this study identified the gaps in occupational therapy models of practice and presents a novel approach, the PAIRE (Recognize Privilege, Acknowledge Injustice, and Reframe Perspective to Reach Equity) Model. PAIRE is focused on achieving occupational equity through the reciprocal and intersectional impact of the provider/team, the person/people seeking occupational therapy, and the occupation-in-context, with continuous influences of access, context, and justice. We describe the components of PAIRE and illustrate its functionality in education, research, and clinical practice contexts as well as case examples.

Developmental delay in infants and toddlers with sickle cell disease: a systematic review.

AIM: To summarize developmental delay among infants and toddlers with sickle cell disease (SCD). METHOD: This systematic review included studies that reported developmental outcomes of children with SCD between 0 months and 48 months of age and followed standards set forth by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: Ten studies were included, describing 596 unique developmental assessments. The rate of developmental delay ranged from 17.5% to 50% and increased with age. Cognition was the only domain included in all studies and the most frequently identified delay. One study reported that more severe SCD genotypes predicted worse development, while five studies reported no difference in rates of developmental delay across genotypes. INTERPRETATION: These findings emphasize the need for standardized screening to identify children with SCD at risk of delay at a young age to facilitate appropriate referrals for therapeutic intervention. Frequent and comprehensive developmental screening is necessary among all SCD genotypes.

Stress and the Home Environment in Caregivers of Children with Sickle Cell.

OBJECTIVE: Caregivers of young children with chronic illnesses are at high risk for elevated levels of stress and mental health symptoms. This study examined stress and mental health symptoms as well as the socioeconomic status (SES) and home environments of a cohort of caregivers of infants and toddlers with sickle cell disease (SCD). METHODS: Forty-two caregivers of infants and toddlers (aged 1-34 months) with SCD completed the Brief Symptom Inventory (BSI) and Parent Stress Index (PSI). The Home Observation for Measurement of the Environment (HOME) was used to assess family living environments. RESULTS: Compared to test norms, caregivers reported high levels of situational/demographic life stress [mean difference (MD) 5.7, p = .003] and child distractibility/hyperactivity (MD 3.62, p = .001) on the PSI. However, no significant differences in psychological symptoms of distress were noted on the BSI. Caregivers scored significantly lower than norms on PSI subdomains of acceptability (MD -1.88, p = .03), competence (MD -3.11, p = .002), depression (MD -3.94, p < .001), and the overall parent domain (MD -12.55, p = .005). Significant correlations were found between PSI scores and the HOME and between SES and the HOME. CONCLUSION: Caregivers of infants and toddlers with SCD experience elevated levels of life stress but, in turn, endorse high acceptance of their child and self-competence in parenting. Although life stress may be high in this population, symptoms of psychological distress were not identified. Caregivers reporting elevated life and illness-specific stressors may benefit from environmental supports and interventions.

Validation of the fine motor subtest of the Bayley-III with children with sickle cell disease using Rasch analysis.

BACKGROUND: Children with sickle cell disease (SCD) are at risk for fine motor (FM) delays; however, screening for FM impairments is not common among young children with SCD. The Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III) is the most commonly used performance-based developmental assessment. We aim to determine if the FM subtest of the Bayley-III is structured hierarchically in accordance with development and comprehensively evaluates FM development in children with SCD. METHODS: Bayley-III assessments were completed between October 2009 and December 2013. The Bayley-III FM screening test, a shorter and more rapid method of assessing for FM impairments, was not directly administered to participants. Screening test scores were calculated from full Bayley-III scores. RESULTS: Rasch analysis was performed using WINSTEPS. Sixty children with SCD were included in the final Rasch model. The Rasch-generated Wright map, which jointly positions items and persons on the same latent trait, illustrated that the FM items were slightly skewed towards more challenging items, indicating more difficult items may be overrepresented. High item separation values were reported (17.4), and item outfit statistics were less than 1.7. More than one third of items demonstrated overfit, indicating possible item redundancy. The FM subtest and the screening test, a shorter and faster method of assessing skills, were highly correlated (r = 0.993, p < 0.001). CONCLUSION: The Bayley-III FM subtest is structured hierarchically, aligning with motor development, and comprehensively evaluates FM development in children with SCD. The test could be improved by reordering items, removing overfitting items and modifying screening test items to capture all ranges of development. The screening test is comprehensive and has high potential clinical utility among children with SCD.

High-fidelity mapping of repetition-related changes in the parietal memory network.

fMRI studies of human memory have identified a "parietal memory network" (PMN) that displays distinct responses to novel and familiar stimuli, typically deactivating during initial encoding but robustly activating during retrieval. The small size of PMN regions, combined with their proximity to the neighboring default mode network, makes a targeted assessment of their responses in highly sampled subjects important for understanding information processing within the network. Here, we describe an experiment in which participants made semantic decisions about repeatedly-presented stimuli, assessing PMN BOLD responses as items transitioned from experimentally novel to repeated. Data are from the highly-sampled subjects in the Midnight Scan Club dataset, enabling a characterization of BOLD responses at both the group and single-subject level. Across all analyses, PMN regions deactivated in response to novel stimuli and displayed changes in BOLD activity across presentations, but did not significantly activate to repeated items. Results support only a portion of initially hypothesized effects, in particular suggesting that novelty-related deactivations may be less susceptible to attentional/task manipulations than are repetition-related activations within the network. This in turn suggests that novelty and familiarity may be processed as separable entities within the PMN.

Behavioral interventions for reducing head motion during MRI scans in children.

A major limitation to structural and functional MRI (fMRI) scans is their susceptibility to head motion artifacts. Even submillimeter movements can systematically distort functional connectivity, morphometric, and diffusion imaging results. In patient care, sedation is often used to minimize head motion, but it incurs increased costs and risks. In research settings, sedation is typically not an ethical option. Therefore, safe methods that reduce head motion are critical for improving MRI quality, especially in high movement individuals such as children and neuropsychiatric patients. We investigated the effects of (1) viewing movies and (2) receiving real-time visual feedback about head movement in 24 children (5-15 years old). Children completed fMRI scans during which they viewed a fixation cross (i.e., rest) or a cartoon movie clip, and during some of the scans they also received real-time visual feedback about head motion. Head motion was significantly reduced during movie watching compared to rest and when receiving feedback compared to receiving no feedback. However, these results depended on age, such that the effects were largely driven by the younger children. Children older than 10 years showed no significant benefit. We also found that viewing movies significantly altered the functional connectivity of fMRI data, suggesting that fMRI scans during movies cannot be equated to standard resting-state fMRI scans. The implications of these results are twofold: (1) given the reduction in head motion with behavioral interventions, these methods should be tried first for all clinical and structural MRIs in lieu of sedation; and (2) for fMRI research scans, these methods can reduce head motion in certain groups, but investigators must keep in mind the effects on functional MRI data.

Awareness, access, and communication: provider perspectives on early intervention services for children with sickle cell disease.

Purpose: This study aimed to identify determinants influencing the utilization of early intervention services among young children with sickle cell disease (SCD) based on perspectives from medical and early intervention providers. Design and methods: Early intervention and medical providers from the catchment area surrounding St. Jude Children's Research Hospital and Washington University were recruited (20 total providers). Interviews were completed over the phone and audio recorded. All interviews were transcribed verbatim, coded, and analyzed using inductive thematic analysis. Results: Three overarching themes were identified from both groups: Awareness (e.g., lack of awareness about the EI system and SCD), Access (e.g., difficulties accessing services), and Communication (e.g., limited communication between medical and early intervention providers, and between providers and families). Although these three themes were shared by medical and early intervention providers, the differing perspectives of each produced subthemes unique to the two professional fields. Conclusions: Early intervention services can limit the neurodevelopmental deficits experienced by young children with SCD; however, most children with SCD do not receive these services. The perspectives of early intervention and medical providers highlight several potential solutions to increase early intervention utilization among young children with SCD.

Referent data for investigations of upper limb accelerometry: harmonized data from three cohorts of typically-developing children.

Aim: The rise of wearable sensing technology shows promise for addressing the challenges of measuring motor behavior in pediatric populations. The current pediatric wearable sensing literature is highly variable with respect to the number of sensors used, sensor placement, wearing time, and how data extracted from the sensors are analyzed. Many studies derive conceptually similar variables via different calculation methods, making it hard to compare across studies and clinical populations. In hopes of moving the field forward, this report provides referent upper limb wearable sensor data from accelerometers on 25 variables in typically-developing children, ages 3-17 years. Methods: This is a secondary analysis of data from three pediatric cohorts of children 3-17 years of age. Participants (n = 222) in the cohorts wore bilateral wrist accelerometers for 2-4 days for a total of 622 recording days. Accelerometer data were reprocessed to compute 25 variables that quantified upper limb movement duration, intensity, symmetry, and complexity. Analyses examined the influence of hand dominance, age, gender, reliability, day-to-day stability, and the relationships between variables. Results: The majority of variables were similar on the dominant and non-dominant sides, declined slightly with age, and were not different between boys and girls. ICC values were moderate to excellent. Variation within individuals across days generally ranged from 3% to 32%. A web-based R shiny object is available for data viewing. Interpretation: With the use of wearable movement sensors increasing rapidly, these data provide key, referent information for researchers as they design studies, and analyze and interpret data from neurodevelopmental and other pediatric clinical populations. These data may be of particularly high value for pediatric rare diseases.

MeTooOT: Sexual Harassment Experiences of Occupational Therapy Academics and Recommendations for Systemic Change.

Sexual harassment is pervasive in academic health fields. Although a predominantly female profession, early career academics and trainees in occupational therapy (OT) remain vulnerable to sexual harassment. We aimed to describe experiences of sexual harassment of female-identifying academic OT practitioners. We conducted surveys and interviews using Interpretive Phenomenological Analysis to examine participants' experiences. Ten participants completed the survey and/or interview. Experiences ranged from inappropriate comments to persistent sexual assault. Four themes (blurred lines, unbalanced consequences, "how did I get here?" and "we don't talk about it") were generated based on participant responses. Power dynamics and the cultures and values of the OT profession were underlying elements of all themes. The consequences of sexual harassment were severe and affected personal and professional growth. For OT research and education to thrive, stronger support for victims and consistent, appropriate consequences for perpetrators are necessary to minimize negative outcomes for victims.

Neuroimaging and Neurological Outcomes in Perinatal Arterial Ischemic Stroke: A Systematic Review and Meta-Analysis.

BACKGROUND: Prediction of outcomes in perinatal arterial ischemic stroke (PAIS) is challenging. We performed a systematic review and meta-analysis to determine whether infarct characteristics can predict outcomes in PAIS. METHODS: A systematic search was conducted using five databases in January 2023. Studies were included if the sample included children with neonatal or presumed PAIS; if infarct size, location, or laterality was indicated; and if at least one motor, cognitive, or language outcome was reported. The level of evidence and risk of bias were evaluated using the Risk of Bias in Non-Randomized Studies of Interventions tool. Meta-analyses were conducted comparing infarct size or location with neurological outcomes when at least three studies could be analyzed. RESULTS: Eighteen full-text articles were included in a systematic review with nine included in meta-analysis. Meta-analyses revealed that small strokes were associated with a lower risk of cerebral palsy/hemiplegia compared with large strokes (risk ratio [RR] = 0.263, P = 0.001) and a lower risk of epilepsy (RR = 0.182, P < 0.001). Middle cerebral artery (MCA) infarcts were not associated with a significantly different risk of cerebral palsy/hemiplegia compared with non-MCA strokes (RR = 1.220, P = 0.337). Bilateral infarcts were associated with a 48% risk of cerebral palsy/hemiplegia, a 26% risk of epilepsy, and a 58% risk of cognitive impairment. CONCLUSIONS: Larger stroke size was associated with worse outcomes across multiple domains. Widely heterogeneous reporting of infarct characteristics and outcomes limits the comparison of studies and the analysis of outcomes. More consistent reporting of infarct characteristics and outcomes will be important to advance research in this field.

Going Beyond Conventional Assessment of Developmental Motor Disorders: Exploring Video Methods for Early Identification Among Children 0 to 3 Years.

Motor skills and movement-related functioning significantly shape how children experience and interact with the world around them. Among infants and young children, developmental motor disorders contribute to delays with motor, cognitive, and psychosocial development. Early and accurate identification of these disorders is necessary to facilitate timely access to therapeutic interventions that minimize the long-term effects of disability on everyday activities and participation. In the United States, motor assessments commonly used among children 0 to 3 years focus on completion of specific motor skills at a single point in time, which provides only a part of the greater picture that is a child's motor and movement-related functioning. Video-capture methods, like the General Movements Assessment (GMA) and the Infant Motor Profile (IMP), offer greater accuracy and predictive power to (1) identify motor deficits in young children and (2) facilitate early access to supportive, therapeutic intervention.

Validation of actigraphy for sleep measurement in children with cerebral palsy.

OBJECTIVES: Sleep issues are common in children with cerebral palsy (CP), although there are challenges in obtaining objective data about their sleep patterns. Actigraphs measure movement to quantify sleep but their accuracy in children with CP is unknown. Our goals were to validate actigraphy for sleep assessment in children with CP and to study their sleep patterns in a cross-sectional cohort study. METHODS: We recruited children with (N = 13) and without (N = 13) CP aged 2-17 years (mean age 9 y 11mo [SD 4 y 10mo] range 4-17 y; 17 males, 9 females; 54% spastic quadriplegic, 23% spastic diplegic, 15% spastic hemiplegic, 8% unclassified CP). We obtained wrist and forehead actigraphy with concurrent polysomnography for one night, and home wrist actigraphy for one week. We developed actigraphy algorithms and evaluated their accuracy (agreement with polysomnography-determined sleep versus wake staging), sensitivity (sleep detection), and specificity (wake detection). RESULTS: Our actigraphy algorithms had median 72-80% accuracy, 87-91% sensitivity, and 60-71% specificity in children with CP and 86-89% accuracy, 88-92% sensitivity, and 70-75% specificity in children without CP, with similar accuracies in wrist and forehead locations. Our algorithms had increased specificity and accuracy compared to existing algorithms, facilitating detection of sleep disruption. Children with CP showed lower sleep efficiency and duration than children without CP. CONCLUSIONS: Actigraphy is a valid tool for sleep assessment in children with CP. Children with CP have worse sleep efficiency and duration.

Activity competence among infants and toddlers with developmental disabilities: Rasch analysis of the Infant Toddler Activity Card Sort (ITACS).

BACKGROUND: Development is rapid in the first years of life. Developmental delays appearing during this critical period have the potential to persist throughout the child's life. Available standardized assessments for this age record a child's ability to successfully complete discrete skills but fail to capture whether the child incorporates those skills into daily routines that are meaningful to the child and family. The Infant Toddler Activity Card Sort (ITACS) is a newly developed photograph-based early intervention tool to measure the participation-related concept of activity competence using caregiver report. The purpose of the present study was to use Rasch analysis to determine if ITACS items comprehensively measure the construct of child activity competence. RESULTS: A total of 60 child/caregiver dyads participated. The dichotomous caregiver-reported responses (present vs. absent) on the 40 individual ITACS items were used in Rasch analysis, and three iterations of the model were completed. The final model included 51 child/caregiver dyads and 67 ITACS assessments with a good spread of individual ability measure (6.47 logits). All items demonstrated adequate infit except for "sleeping" (range 0.68-1.54). Five items (sleeping, eating at restaurants, brushing teeth, crawling, and interact with pets) demonstrated high Mean Square (MNSQ) outfit statistics and one (take a bath) demonstrated low MNSQ outfit. ITACS items demonstrated a good spread of item difficulty measures (6.27 logits), and a clear ceiling was observed. Three activity items (smiling, breastfeeding, and playing with adults) were rarely endorsed as concerns. The activities most likely to be reported as challenging were "crying/communicating" and "going to school". Person and item reliability statistics were adequate (0.79 and 0.80, respectively). The separation between individuals and between items were adequate to good (1.96 and 1.99, respectively). CONCLUSIONS: Findings indicate that ITACS items are measuring a unidimensional construct--activity competence in early childhood. The Rasch analysis of caregiver responses suggest that some activities are more likely to be considered challenging and may be important targets for intervention. These results provide evidence to further validate the ITACS as a caregiver report measure and support its use in the early intervention setting to facilitate caregiver driven goal development.

Toward a More Comprehensive Assessment of School Age Children with Hemiplegic Cerebral Palsy.

BACKGROUND: Cerebral palsy (CP) is the leading cause of disability in children. While motor deficits define CP, many patients experience behavioral and cognitive deficits which limit participation. The purpose of this study was to contribute to our understanding of developmental delay and how to measure these deficits among children with CP. METHODS: Children 5 to 15 years with hemiplegic CP were recruited. Cognition and motor ability were assessed. The brain injury associated with observed motor deficits was identified. Accelerometers measured real-world bilateral upper extremity movement and caregivers completed behavioral assessments. RESULTS: Eleven children participated, 6 with presumed perinatal stroke. Four children scored below average intelligence quotient while other measures of cognition were within normal limits (except processing speed). Motor scores confirmed asymmetrical deficits. Approximately one third of scores indicated deficits in attention, behavior, or depression. CONCLUSIONS: Our findings corroborate that children with CP experience challenges that are broader than motor impairment alone. Despite the variation in brain injury, all participants completed study procedures. IMPLICATIONS: Our findings suggest that measuring behavior in children with CP may require a more comprehensive approach and that caregivers are amenable to using online collection tools which may assist in addressing the therapeutic needs of children with CP.

Psychometric Properties of the Infant Toddler Activity Card Sort.

The Infant Toddler Activity Card Sort (ITACS) is a new measure that engages caregivers in goal development by measuring participation in early childhood. Initial evaluation of the ITACS is required to assess its psychometric properties. To evaluate test-retest reliability, concurrent validity, and between-group differences of the ITACS. Caregivers (N = 208) of children 0-3 years, who were typically developing (TD) or had a developmental delay (DD), completed the ITACS and Pediatric Evaluation of Disability Inventory-Computer Adaptive Test (PEDI-CAT) with repeat assessment after 2 weeks later (n = 117). The ITACS demonstrated moderate concurrent validity with the PEDI-CAT. Children with DD had significantly more activity concerns on the ITACS than TD. Adequate test-retest reliability was not achieved. The ITACS is a useful tool for identifying caregiver concerns in activity engagement; interventions can be tailored to address concerns and increase participation in childhood routines.

The Infant Toddler Activity Card Sort: A Caregiver Report Measure of Children's Occupational Engagement in Family Activities and Routines.

Early intervention (EI) therapy services aim to address family-centered goals to facilitate young children's development and participation in meaningful life activities. Current methods to evaluate children in EI assess discrete developmental skills but provide little information on the child's ability to successfully incorporate that skill in everyday life. Furthermore, traditional measures have limited opportunity for parent report, despite parent engagement being a critical component for successful implementation of EI services. A measure that involves parents in the therapeutic process to track family-driven EI goals related to a child's occupational engagement in meaningful family activities and routines is desperately needed. Using a qualitative design and conventional content analysis, we identified 41 distinct activities of infant-toddlers from a cohort of 23 caregivers. Activity items were matched with photographs and validated with experts in pediatric rehabilitation using the Delphi method. The resulting 40 activity/photograph pairs were used to develop a new measure of pediatric occupational engagement, the Infant Toddler Activity Card Sort (ITACS).
