Systematic review of the economic impact of cerebral palsy

Development of algorithms for estimating the Child Health Utility 9D from Caregiver Priorities and Child Health Index of Life with Disability

PURPOSE

The primary aim was to determine Child Health Utility 9D (CHU9D) utilities from the Caregiver Priorities and Child Health Index of Life with Disabilities (CPCHILD) for non-ambulatory children with cerebral palsy (CP).

METHODS

One hundred and eight surveys completed by Australian parents/caregivers of children with CP were analysed. Spearman's coefficients were used to investigate the correlations between the two instruments. Ordinary least square, robust MM-estimator, and generalised linear models (GLM) with four combinations of families and links were developed to estimate CHU9D utilities from either the CPCHILD total score or CPCHILD domains scores. Internal validation was performed using 5-fold cross-validation and random sampling validation. The best performing algorithms were identified based on mean absolute error (MAE), concordance correlation coefficient (CCC), and the difference between predicted and observed means of CHU9D.

RESULTS

Moderate correlations (ρ 0.4-0.6) were observed between domains of the CHU9D and CPCHILD instruments. The best performing algorithm when considering the CPCHILD total score was a generalised linear regression (GLM) Gamma family and logit link (MAE = 0.156, CCC = 0.508). Additionally, the GLM Gamma family logit link using CPCHILD comfort and emotion, quality of life, and health domain scores also performed well (MAE = 0.152, CCC = 0.552).

CONCLUSION

This study established algorithms for estimating CHU9D utilities from CPCHILD scores for non-ambulatory children with CP. The determined algorithms can be valuable for estimating quality-adjusted life years for cost-utility analysis when only the CPCHILD instrument is available. However, further studies with larger sample sizes and external validation are recommended to validate these findings.

The application of virtual reality to home-based rehabilitation for children and adolescents with cerebral palsy: A systematic review and meta-analysis

BACKGROUND

Home-based rehabilitation enables children and families to participate in therapeutic activities built into their daily routines without the barriers of arrangement and transportation to facilities. Virtual reality is an emerging technology which has shown promising outcomes in rehabilitation.

PURPOSE

This systematic review aims to examine the feasibility and effects of virtual reality-enhanced home rehabilitation on Body functions and structures, Activity, and Participation outcomes in children and adolescents with cerebral palsy.

METHODS

Interventional studies were searched across five biomedical databases on November 26, 2022. Two independent reviewers conducted study selection, data extraction, and quality assessment. The Physiotherapy Evidence Database scale and National Institutes of Health Study Quality Assessment Tools were used to evaluate the quality of included studies. Meta-analysis was performed to examine the effects of the intervention.

RESULTS

Eighteen studies were included in this review. Home-based virtual reality rehabilitation appears feasible with effects on upper extremity and gross motor function, strength, bone density, cognition, balance, walking, daily activity performance, and participation. Meta-analyses revealed significant improvements in hand function (SMD = 0.41, p= .003), gross motor function (SMD = 0.56, p= .0002), and walking capacity (SMD = 0.44, p= .01) following home-based virtual reality intervention.

CONCLUSION

Home-based virtual reality may serve as an adjunct to conventional facility-based therapy to promote participation in therapeutic exercises and maximize rehabilitation outcomes. Further properly designed randomized controlled trials using valid and reliable outcome measures with adequately powered sample sizes are warranted to enhance the current body of evidence using home-based virtual reality in cerebral palsy rehabilitation.

Knowledge translation strategies used to promote evidence-based interventions for children with cerebral palsy: a scoping review

BACKGROUND

Cerebral palsy (CP) is the most common childhood physical disability, imposing substantial costs on individuals and society. Early interventions that promote brain optimization and reorganization are vital for children with CP. Integrating early evidence-based practice (EBP) remains challenging but enhances functional outcomes.

METHODS

Following a scoping review methodology, databases were searched to identify studies examining the impact of knowledge translation (KT) strategies for pediatric CP interventions. Extraction included study characteristics, methodology, KT strategies, barriers, and facilitators. Numerical and inductive content analysis identified themes among KT strategies. A final stakeholder consultation to discuss the results was conducted.

RESULTS

This review included seventeen articles. Common outcomes included participant change in EBP knowledge and behaviour. Common barriers included a need for more resources, protected time, and funding. Most studies followed a multifaceted KT approach. Various KT strategies were used, primarily mentoring, workshops, case studies, and online tools.

INTERPRETATION

Results underscored the need for tailored KT strategies for implementing EBP for children with CP. Additionally, user-friendly KT tools and involving mentors to facilitate the intervention can haste EBP uptake. Successful adoption depends on challenges in healthcare settings. This study provides insights into current KT strategies for advancing best practices for children with CP.

The experiences of families of children with cerebral palsy and complex disability after three years accessing the National Disability Insurance Scheme

INTRODUCTION

In Australia, children with cerebral palsy and complex disability receive funded supports through the National Disability Insurance Scheme (NDIS). This individualised funding scheme requires parents to navigate and advocate on behalf of their child, supported by expert reports, recommendations, and allied health services. Supports aim to enable participation in all areas of daily life, which may be otherwise largely inaccessible to children with complex disability and their families. This study aimed to explore the experiences of families of children with complex disability after 3 years accessing the NDIS.

METHODS

A qualitative research design with a demographic questionnaire and in-depth interview was undertaken. Purposive sampling was used to recruit participants from one organisation providing occupational therapy and other allied health services. Data analysis implemented Braun and Clarke's thematic approach to examine the experiences of participants.

CONSUMER AND COMMUNITY INVOLVEMENT

This research was conducted with a registered National Disability Insurance Scheme provider to give voice to parent consumers who raise children with complex disability.

FINDINGS

Seven mothers and one father (N = 8) of children with complex disability were interviewed. Most parents reported increased success and satisfaction navigating the scheme. Five overall themes were generated from the data: pivotal roles of families, parental empowerment, life-changing equipment, the fallibility of the scheme, and a critical scheme.

CONCLUSION

Parents reported reliance on the scheme for their child's basic daily care and a more enriched life for their child and family. Parents were grateful for the scheme but experienced inconsistencies, navigation difficulties, and variable choice and control. Most parents had fears about the sustainability of the scheme, translating into uncertainty about their child's future. Allied health professionals, including occupational therapists, are key advocates for children with complex disability and their families. Collaboration through sharing knowledge and skills to support children, their families, and carers is key to empowering parents to navigate the NDIS.

PLAIN LANGUAGE SUMMARY

The National Disability Insurance Scheme (NDIS) provides funding for people with permanent and significant disability. Children with cerebral palsy (and other complex disability) are lifetime users of the NDIS. For children with complex disability, their families are crucial to ensuring that their daily needs are being met, including providing medication. Previous research indicated that parents rely on the NDIS to support their children; however, there have been various challenges such as long wait times for equipment and difficulty understanding how to use the scheme. This study explored the experiences of families of children with complex disability, after more than 3 years of being an NDIS participant. Eight parents from one therapy service provider completed a short questionnaire about themselves, their child, and their family, followed by an interview with the first author. Four authors (occupational therapists) worked together to design and implement this study. The findings highlighted several key points: the important role of parents as caregivers; parents became more knowledgeable and confident to navigate the NDIS with time; equipment funded by the NDIS was life-changing; the NDIS has ongoing issues; and the crucial nature of the NDIS. Occupational therapists can be extremely important to families, including with supporting families to navigate the NDIS and advocating for them. Occupational therapists must stay current with their knowledge of the NDIS as they provide lifetime support, including prescribing equipment, technology, and home modifications.

Health care resource use in preschool children with cerebral palsy

AIM

To estimate the burden of disease and evaluate which factors affect health care resource use (HCRU) in young children with cerebral palsy (CP).

METHOD

Data were collected as part of a prospective, longitudinal cohort study of children with CP born in Queensland, Australia between 2006 and 2009. HCRU questionnaires were administered at six time points. Data on resource use, socio-demographics, and disease severity were collected. Costs were sourced from Medicare, the Australian National Hospital Cost Data Collection, and market prices. A generalized linear model was used to identify factors influencing CP-related costs.

RESULTS

A total of 794 questionnaires were completed by 222 participants (mean = 3.6 per participant). Physiotherapy (94%, n = 208) was the most widely accessed allied health care therapy; almost half of the participants (45%; 354 of 794) reported one or more hospital admissions. From the health care funder perspective, a child with CP costs on average A$24 950 per annum (A$12 475 per 6 months). Higher costs were associated with increased motor impairment (Gross Motor Function Classification System, p < 0.001) and increased comorbidities (p = 0.012).

INTERPRETATION

HCRU in preschool children with CP can be analysed according to disease severity. Both increased motor impairments and increased comorbidities were associated with higher health care costs.

Social capital of families of children with neurodevelopmental disabilities in South India

AIM

To investigate the social capital of families with children with neurodevelopmental disabilities in South India receiving a community-based early intervention (Enabling Inclusion®) program and to explore determinants and associations between social capital and program duration, socio-demographic factors, family empowerment, and caregiver burden.

METHOD

Using purposive sampling in a cross-sectional study design, 217 families (n = 71 received short Enabling Inclusion [<5 months]; n = 146 received long Enabling Inclusion [>9 months]) were recruited and completed the Short Adapted Social Capital Tool (SASCAT: cognitive, structural), measures of family empowerment, and caregiver strain. Descriptive statistics, regression, and correlations were used for analyses.

RESULTS

In 52.1% of participants, low cognitive and structural social capital was observed. Higher odds of low structural social capital were observed for mothers with primary versus secondary education (adjusted odds ratio [OR] = 0.35; 95% confidence interval [CI] 0.13-0.90; p = 0.029); and caregivers of children with cerebral palsy versus autism (OR = 4.66; 95% CI 1.02-21.21; p = 0.046). Significant associations were found between structural social capital, the child's age, and support group membership (χ2 = 6.29; 4.70; degrees of freedom [df] = 2; 1; p = 0.04; p = 0.02 respectively), as well as between cognitive social capital and other disability in the family (χ2 = 4.62, df = 1, p = 0.03).

INTERPRETATION

While program duration was not found to mediate social capital, mother's education and child's diagnosis emerged as key influential factors, warranting their consideration in interventions supporting families of children with neurodevelopmental disabilities in low- and-middle-income countries and elsewhere.

Motor imagery ability in children and adolescents with cerebral palsy: a systematic review and evidence map

Background

Cerebral palsy (CP) refers to a group of permanent movement and posture disorders. Motor imagery (MI) therapy is known to provide potential benefits, but data on MI ability in children and adolescents with CP is lacking.

Objective

A systematic review was performed to explore MI abilities in children and adolescents with CP compared to typically developed (TD) subjects.

Methods

We searched on PubMed, Web of Science (WOS), EBSCO, Google Scholar, and PEDro including observational studies. Methodological quality was assessed with the modified Newcastle-Ottawa Scale and evidence map was created to synthesize the evidence qualitatively and quantitatively.

Results

Seven cross-sectional studies were selected, which included 174 patients with CP and 321 TD subjects. Three studies explored explicit MI, two MI-execution synchrony, and four implicit MI domains. Methodological quality ranged from 6 to 8 stars. Moderate evidence supported the absence of differences in vividness between the groups. As there was only limited evidence, establishing a clear direction for the results was not possible, especially for the capacity to generate MI, mental chronometry features, and MI-execution synchrony domains. Moderate evidence supported a lower efficiency in cases for hand recognition, derived from a lower accuracy rate, while reaction time remained similar between the two groups. Moderate evidence indicated that patients with CP and TD controls showed similar features on whole-body recognition.

Conclusion

Moderate evidence suggests that patients with CP present a reduced ability in hand recognition, which is not observed for whole-body recognition compared to healthy controls. Severe limitations concerning sample size calculations and validity of assessment tools clearly limits establishing a direction of results, especially for explicit MI and MI-Execution synchrony domains. Further research is needed to address these limitations to enhance our comprehension of MI abilities in children, which is crucial for prescribing suitable MI-based therapies in this child population.

A big data approach to evaluate receipt of optimal care in childhood cerebral palsy

PURPOSE

Through automated electronic health record (EHR) data extraction and analysis, this project systematically quantified actual care delivery for children with cerebral palsy (CP) and evaluated alignment with current evidence-based recommendations.

METHODS

Utilizing EHR data for over 8000 children with CP, we developed an approach to define and quantify receipt of optimal care, and pursued proof-of-concept with two children with unilateral CP, Gross Motor Function Classification System (GMFCS) Level II. Optimal care was codified as a cluster of four components including physical medicine and rehabilitation (PMR) care, spasticity management, physical therapy (PT), and occupational therapy (OT). A Receipt of Care Score (ROCS) quantified the degree of adherence to recommendations and was compared with the Pediatric Outcomes Data Collection Instrument (PODCI) and Pediatric Quality of Life Inventory (PEDS QL).

RESULTS

The two children (12 year old female, 13 year old male) had nearly identical PMR and spasticity component scores while PT and OT scores were more divergent. Functional outcomes were higher for the child who had higher adjusted ROCS.

CONCLUSIONS

ROCSs demonstrate variation in real-world care delivered over time and differentiate between components of care. ROCSs reflect overall function and quality of life. The ROCS methods developed are novel, robust, and scalable and will be tested in a larger sample.IMPLICATIONS FOR REHABILITATIONOptimal practice, with an emphasis on integrated multidisciplinary care, can be defined and quantified utilizing evidence-based recommendations.Receipt of optimal care for childhood cerebral palsy can be scored using existing electronic health record data.Big Data approaches can contribute to the understanding of current care and inform approaches for improved care.

A predictive model for perinatal hypoxic ischemic encephalopathy using linked maternal and neonatal hospital data

PURPOSE

To build an evidence-based model to estimate case-specific risk of perinatal hypoxic ischemic encephalopathy.

METHODS

A retrospective, cross-sectional study of all births in Hawaii, Michigan, and New Jersey between 2010 and 2015, using linked maternal labor/delivery and neonatal birth records. Stepwise logistic regression and competitive Akaike information criterion were used to identify the most parsimonious model. Predictive ability of the model was measured with bootstrapped optimism-adjusted area under the ROC curve.

RESULTS

Among 836,216 births there were 376 (0.45 per 1000) cases of hypoxic ischemic encephalopathy. The final model included 28 variables, 24 associated with increased risk, and 4 that were protective. The optimism-adjusted area under the ROC curve was 0.84. Estimated risk in the study population ranged from 1 in ∼323,000 to 1 in 2.5. The final model confirmed known risk factors (e.g., sentinel events and shoulder dystocia) and identified novel risk factors, such as maternal race and insurance status.

CONCLUSION

Our study shows that risk of perinatal hypoxic ischemic encephalopathy injury can be estimated with high confidence. Our model fills a notable gap in the study of hypoxic ischemic encephalopathy prevention: the estimation of risk, particularly in the United States population which is unique with respect to racial and socioeconomic disparities.

The critical need to accelerate cerebral palsy research with consumer engagement, global networks, and adaptive designs

The prevalence of cerebral palsy (CP) varies globally, with higher rates and burden of disease in low- and middle-income countries. CP is a lifelong condition with no cure, presenting diverse challenges such as motor impairment, epilepsy, and mental health disorders. Research progress has been made but more is needed, especially given consumer demands for faster advancements and improvements in the scientific evidence base for interventions. This paper explores three strategies to accelerate CP research: consumer engagement, global clinical trial networks, and adaptive designs. Consumer engagement involving individuals with lived experience enhances research outcomes. Global clinical trial networks provide efficiency through larger and more diverse participant pools. Adaptive designs, unlike traditional randomized controlled trials, allow real-time modifications based on interim analyses, potentially answering complex questions more efficiently. The establishment of a CP Global Clinical Trials Network, integrating consumer engagement, global collaboration, and adaptive designs, marks a paradigm shift. The Network aims to address consumer-set research priorities. While challenges like ethical considerations and capacity building exist, the potential benefits for consumers, clinicians, researchers, and funding bodies are substantial. This paper underscores the urgency of transforming CP research methodologies for quicker translation of novel treatments into clinical practice to improve quality of life for those with CP.

Fathers' experiences of caring for children living with cerebral palsy: A qualitative study in a low resourced socioeconomic context, Ghana

BACKGROUND

In Ghana, little is known about fathers' experiences caring for children with cerebral palsy.

PURPOSE

The purpose of this study is to explore a. the caregiving demand and burden on fathers of children with cerebral palsy and b. describe the caregiving consequences and coping strategies of fathers of children with cerebral palsy.

DESIGN AND METHODS

The study utilized an exploratory, descriptive qualitative approach with a sample size of fifteen fathers purposively selected. The study used a semi-structured interview guide to conduct a one-on-one interview with participants. The analysis performed was thematic and content analysis.

RESULTS

The results revealed complexities of care demand and burden; thus, meeting the child's needs resulted in physical and mental exhaustion, frequent hospital visits, and substantial financial implications for fathers.

CONCLUSIONS

We conclude that the family, particularly fathers, need support to embrace the challenging care roles as parents to children with cerebral palsy. It is evident that caring for children is mainly reserved for mothers in the African context. However, the demanding nature of care for a child with a developmental disability requires the involvement of both parents to meet the child's care needs and reduce the caregiver's care burden.

PRACTICE IMPLICATIONS

Health professionals, particularly nurses must initiate and advocate for fathers' active participation in daily childcare. Tailored supportive care for families with children with disabilities in sub-Saharan Africa is required.

Adults with Cerebral Palsy: Navigating the Complexities of Aging

The goal of this narrative review is to highlight the healthcare challenges faced by adults with cerebral palsy, including the management of long-term motor deficits, difficulty finding clinicians with expertise in these long-term impairments, and scarcity of rehabilitation options. Additionally, this narrative review seeks to examine potential methods for maintaining functional independence, promoting social integration, and community participation. Although the brain lesion that causes the movement disorder is non-progressive, the neurodevelopmental disorder worsens from secondary complications of existing sensory, motor, and cognitive impairments. Therefore, maintaining the continuum of care across one's lifespan is of utmost importance. Advancements in healthcare services over the past decade have resulted in lower mortality rates and increased the average life expectancy of people with cerebral palsy. However, once they transition from adolescence to adulthood, limited federal and community resources, and health care professionals' lack of expertise present significant obstacles to achieving quality healthcare and long-term benefits. This paper highlights the common impairments seen in adults with cerebral palsy. Additionally, it underscores the critical role of long-term healthcare and management to prevent functional decline and enhance quality of life across physical, cognitive, and social domains.

Prenatal Intravenous Magnesium at 30-34 Weeks' Gestation and Neurodevelopmental Outcomes in Offspring: The MAGENTA Randomized Clinical Trial

Importance

Intravenous magnesium sulfate administered to pregnant individuals before birth at less than 30 weeks' gestation reduces the risk of death and cerebral palsy in their children. The effects at later gestational ages are unclear.

Objective

To determine whether administration of magnesium sulfate at 30 to 34 weeks' gestation reduces death or cerebral palsy at 2 years.

Design, Setting, and Participants

This randomized clinical trial enrolled pregnant individuals expected to deliver at 30 to 34 weeks' gestation and was conducted at 24 Australian and New Zealand hospitals between January 2012 and April 2018.

Intervention

Intravenous magnesium sulfate (4 g) was compared with placebo.

Main Outcomes and Measures

The primary outcome was death (stillbirth, death of a live-born infant before hospital discharge, or death after hospital discharge before 2 years' corrected age) or cerebral palsy (loss of motor function and abnormalities of muscle tone and power assessed by a pediatrician) at 2 years' corrected age. There were 36 secondary outcomes that assessed the health of the pregnant individual, infant, and child.

Results

Of the 1433 pregnant individuals enrolled (mean age, 30.6 [SD, 6.6] years; 46 [3.2%] self-identified as Aboriginal or Torres Strait Islander, 237 [16.5%] as Asian, 82 [5.7%] as Māori, 61 [4.3%] as Pacific, and 966 [67.4%] as White) and their 1679 infants, 1365 (81%) offspring (691 in the magnesium group and 674 in the placebo group) were included in the primary outcome analysis. Death or cerebral palsy at 2 years' corrected age was not significantly different between the magnesium and placebo groups (3.3% [23 of 691 children] vs 2.7% [18 of 674 children], respectively; risk difference, 0.61% [95% CI, -1.27% to 2.50%]; adjusted relative risk [RR], 1.19 [95% CI, 0.65 to 2.18]). Components of the primary outcome did not differ between groups. Neonates in the magnesium group were less likely to have respiratory distress syndrome vs the placebo group (34% [294 of 858] vs 41% [334 of 821], respectively; adjusted RR, 0.85 [95% CI, 0.76 to 0.95]) and chronic lung disease (5.6% [48 of 858] vs 8.2% [67 of 821]; adjusted RR, 0.69 [95% CI, 0.48 to 0.99]) during the birth hospitalization. No serious adverse events occurred; however, adverse events were more likely in pregnant individuals who received magnesium vs placebo (77% [531 of 690] vs 20% [136 of 667], respectively; adjusted RR, 3.76 [95% CI, 3.22 to 4.39]). Fewer pregnant individuals in the magnesium group had a cesarean delivery vs the placebo group (56% [406 of 729] vs 61% [427 of 704], respectively; adjusted RR, 0.91 [95% CI, 0.84 to 0.99]), although more in the magnesium group had a major postpartum hemorrhage (3.4% [25 of 729] vs 1.7% [12 of 704] in the placebo group; adjusted RR, 1.98 [95% CI, 1.01 to 3.91]).

Conclusions and Relevance

Administration of intravenous magnesium sulfate prior to preterm birth at 30 to 34 weeks' gestation did not improve child survival free of cerebral palsy at 2 years, although the study had limited power to detect small between-group differences.

Out-of-pocket costs for families and people living with cerebral palsy in Australia

The most recent cost estimates of cerebral palsy (CP) in Australia did not include out-of-pocket costs for families. This study aimed to: 1) describe and estimate out-of-pocket costs for people with CP and their families by age and gross motor function classification system (GMFCS) level; 2) measure financial distress. A cross-sectional quantitative survey design was used with qualitative approaches to analyse open-ended questions. A CP-specific out-of-pocket costs survey was co-designed with people with lived experience. Adults with CP and carers were recruited from Australian population-based CP Registers and via social media. Sociodemographic variables were analysed descriptively and median (IQR) expenses for health, assistive technology, personal care, housing, occupation, transport, leisure, respite and holidays, by age (0-6; 7-17; 18 years +) and gross motor function [GMFCS level I-II vs III-V] were calculated. The In Charge Financial Distress/Financial Wellbeing Scale measured financial distress. Regression analyses were conducted to investigate costs and financial distress. Additional out-of-pocket costs itemised in open-ended questions were charted. Comments were thematically analysed using the framework approach. 271 surveys were completed for children 0-6 years (n = 47), children/adolescents 7-17 years (n = 124) and adults (n = 100). 94% of participants had out-of-pocket costs associated with CP, with an overall annual median of $4,460 Australian dollars (IQR $11,955). After controlling for income, private insurance and disability funding, the GMFCS III-V group had costs two times higher than the GMFCS I-II group (2.01; 95% CI 1.15-3.51). Age was not significantly associated with costs. 36% of participants had high to overwhelming financial distress; this was not associated with age or GMFCS level after controlling for financial factors. Families had several additional disability costs. Open-ended responses revealed experiences of financial concern were influenced by funding scheme experiences, reduced income, uncertainty, access to support networks and an inability to afford CP-related costs. Cost estimates and financial distress indicators should inform policy, funding and clinical decisions when planning interventions to support people with CP and their families.

Unsupervised abnormality detection in neonatal MRI brain scans using deep learning

Analysis of 3D medical imaging data has been a large topic of focus in the area of Machine Learning/Artificial Intelligence, though little work has been done in algorithmic (particularly unsupervised) analysis of neonatal brain MRI's. A myriad of conditions can manifest at an early age, including neonatal encephalopathy (NE), which can result in lifelong physical consequences. As such, there is a dire need for better biomarkers of NE and other conditions. The objective of the study is to improve identification of anomalies and prognostication of neonatal MRI brain scans. We introduce a framework designed to support the analysis and assessment of neonatal MRI brain scans, the results of which can be used as an aid to neuroradiologists. We explored the efficacy of the framework through iterations of several deep convolutional Autoencoder (AE) unsupervised modeling architectures designed to learn normalcy of the neonatal brain structure. We tested this framework on the developing human connectome project (dHCP) dataset with 97 patients that were previously categorized by severity. Our framework demonstrated the model's ability to identify and distinguish subtle morphological signatures present in brain structures. Normal and abnormal neonatal brain scans can be distinguished with reasonable accuracy, correctly categorizing them in up to 83% of cases. Most critically, new brain anomalies originally missed during the radiological reading were identified and corroborated by a neuroradiologist. This framework and our modeling approach demonstrate an ability to improve prognostication of neonatal brain conditions and are able to localize new anomalies.

Manual Abilities and Cognition in Children with Cerebral Palsy: Do Fine Motor Skills Impact Cognition as Measured by the Bayley Scales of Infant Development?

Manual ability may be an important consideration when measuring cognition in children with CP because many items on cognitive tests require fine motor skills. This study investigated the association of fine motor dependent (FMD) and fine motor independent (FMI) items within the cognitive domain (COG) of the Bayley Scales of Infant Development-Third Edition (Bayley-III) and Manual Ability Classification System (MACS) in children with cerebral palsy. Children aged 2 to 8 (3.96 ± 1.68) years were included in this study. MACS levels were assigned at baseline. COG was administrated at baseline (n = 61) and nine months post-baseline (n = 28). The 91 items were classified into FMD (52) and FMI (39). Total raw score, FMD, and FMI scores were calculated. The association between MACS and cognitive scores (total, FMD, and FMI) were evaluated using linear regression and Spearman correlation coefficients. We found total, FMD, and FMI scores decrease significantly as the MACS level increases at the baseline. Both FMD and FMI scores decreased as MACS levels increased (worse function). There was a significant difference between the two slopes, with the FMD scores having a steeper slope. Similar patterns were observed nine months post-baseline. Children with lower manual ability scored lower in the cognitive domain at baseline and 9 months post-baseline. The significant difference in the performance of FMD items and FMI items across MACS levels with a steeper slope of changes in FMD items suggests fine motor skills impact cognition.

The economic burden incurred by families caring for a young child with developmental disability in Uganda

Each year, nearly 30 million children globally are at risk of developmental difficulties and disability as a result of newborn health conditions, with the majority living in resource-constrained countries. This study estimates the annual cost to families related to caring for a young child with developmental disability in Uganda. Nested within a feasibility trial of early care and support for young children with developmental disabilities, this sub-study estimated the cost of illness, the cost of paternal abandonment of the caregiver and the affordability of care by household. Seventy-three caregivers took part in this sub-study. The average annual cost of illness to families was USD 949. The main cost drivers were the cost of seeking care and income lost due to loss of employment. Households caring for a child with a disability spent more than the national average household expenditure, and the annual cost of illness for all households was more than 100% of the national GDP per capita. In addition, 84% of caregivers faced economic consequences and resorted to wealth-reducing coping strategies. Families caring for a child with severe impairment incurred USD 358 more on average than those with mild or moderate impairment. Paternal abandonment was common (31%) with affected mothers losing an average of USD 430 in financial support. Caring for a young child with developmental disability was unaffordable to all the study households. Programmes of early care and support have the potential to reduce these financial impacts. National efforts to curb this catastrophic health expenditure are necessary.

Perspectives on ankle-foot technology for improving gait performance of children with Cerebral Palsy in daily-life: requirements, needs and wishes

BACKGROUND

Ankle-foot orthoses (AFOs) are extensively used as a primary management method to assist ambulation of children with Cerebral Palsy (CP). However, there are certain barriers that hinder their prescription as well as their use as a mobility device in all kinds of daily-life activities. This exploratory research attempts to further understand the existing limitations of current AFOs to promote a better personalization of new design solutions.

METHODS

Stakeholders' (professionals in CP and end-users with CP) perspectives on AFO technology were collected by two online surveys. Respondents evaluated the limitations of current assistive solutions and assessment methods, provided their expectations for a new AFO design, and analyzed the importance of different design features and metrics to enrich the gait performance of these patients in daily-life. Quantitative responses were rated and compared with respect to their perceived importance. Qualitative responses were classified into themes by using content analysis.

RESULTS

130 survey responses from ten countries were analyzed, 94 from professionals and 36 from end-users with CP. The most highly rated design features by both stakeholder groups were the comfort and the ease of putting on and taking off the assistive device. In general, professionals preferred new features to enrich the independence of the patient by improving gait at functional levels. End-users also considered their social acceptance and participation. Health care professionals reported a lack of confidence concerning decision-making about AFO prescription. To some degree, this may be due to the reported inconsistent understanding of the type of assistance required for each pathological gait. Thus, they indicated that more information about patients' day-to-day walking performance would be beneficial to assess patients' capabilities.

CONCLUSION

This study emphasizes the importance of developing new approaches to assess and treat CP gait in daily-life situations. The stakeholders' needs and criteria reported here may serve as insights for the design of future assistive devices and for the follow-up monitoring of these patients.

Validation of the Critical-Care Pain Observation Tool (CPOT) in pediatric patients undergoing orthopedic surgery

Background

Postoperative pain cannot be measured accurately among many children with intellectual and developmental disabilities, resulting in underrecognition or delay in recognition of pain. The Critical-Care Pain Observation Tool (CPOT) is a pain assessment tool that has been widely validated in critically ill and postoperative adults.

Aims

The objective of this study was to validate the CPOT for use with pediatric patients able to self-report and undergoing posterior spinal fusion surgery.

Methods

Twenty-four patients (10-18 years old) scheduled to undergo surgery were consented to this repeated-measure, within-subject study. To examine discriminative and criterion validation, CPOT scores and patients' self-reports of pain intensity were collected prospectively by a bedside rater before, during, and after a nonnociceptive and nociceptive procedure on the day following surgery. Patients' behavioral reactions were video recorded at the bedside and retrospectively viewed by two independent video raters to examine interrater and intrarater reliability of CPOT scores.

Results

Discriminative validation was supported with higher CPOT scores during the nociceptive procedure than during the nonnociceptive procedure. Criterion validation was supported with a moderate positive correlation between the CPOT scores and the patients' self-reported pain intensity during the nociceptive procedure. A CPOT cutoff score of ≥2 was associated with the maximum sensitivity (61.3%) and specificity (94.1%). Reliability analyses revealed poor to moderate agreement between bedside and video raters and moderate to excellent consistency within video raters.

Conclusions

These findings suggest that the CPOT may be a valid tool to detect pain in pediatric patients in the acute postoperative inpatient care unit after posterior spinal fusion.

Optimal frequency of physical therapy in young children with cerebral palsy: a retrospective pilot study

PURPOSE

To determine the optimal frequency of physical therapy (PT) in young children with cerebral palsy (CP).

METHODS

Twenty-three children (mean age, 47.30 ± 31.95 months) with CP who had undergone both low- and high-frequency PT in an outpatient rehabilitation clinic were analyzed retrospectively. The Gross Motor Function Measure-88 (GMFM-88) score was assessed before and after low- and high-frequency PT.

RESULTS

The high-frequency PT group showed statistically significant improvements of GMFM-88 compared to the low-frequency PT group. In the high-frequency PT group, the improvement in total GMFM-88 scores was greater in children below 36 months of age than in children above 36 months of age. Moreover, the ambulatory group showed greater improvement compared to the non-ambulatory group during high-frequency PT.

CONCLUSIONS

High-frequency PT might benefit gross motor function in children with CP up to 36 months of age. High-frequency PT resulted in improved standing and gait function in the ambulatory group.

Potentially Preventable Hospitalizations Among Adults With Pediatric-Onset Disabilities

OBJECTIVE

To examine the risk of any and specific potentially preventable hospitalizations (PPHs) for adults with cerebral palsy (CP) or spina bifida (SB). We hypothesize that PPH risk is greater among adults with CP/SB compared with the general population.

PATIENTS AND METHODS

Using January 1, 2007, to December 31, 2017, national private administrative claims data (OptumInsight) in the United States, we identified adults with CP/SB (n=10,617). Adults without CP/SB were included as controls (n=1,443,716). To ensure a similar proportion in basic demographics, we propensity-matched our controls with cases in age and sex (n=10,617). Generalized estimating equation models were applied to examine the risk of CP/SB on PPHs. All models were adjusted for age, sex, race/ethnicity, health indicators, US Census Division data, and socioeconomic variables. Adjusted odds ratios were compared within a 4-year follow-up.

RESULTS

Adults with CP/SB had higher risk for any PPH (odds ratio [OR], 4.10; 95% CI, 2.31 to 7.31), and PPHs due to chronic obstructive pulmonary disease/asthma (OR, 1.85; CI, 1.23 to 2.76), pneumonia (OR, 3.01; 95% CI, 2.06 to 4.39), and urinary tract infection (OR, 6.48; 95% CI, 3.91 to 10.75). Cases and controls who had an annual wellness visit had lower PPH risk (OR, 0.52; 95% CI, 0.41 to 0.67); similarly, adults with CP/SB who had an annual wellness visit compared with adults with CP/SB who did not had lower odds of PPH (OR, 0.75; 95% CI, 0.60 to 0.94).

CONCLUSION

Adults with pediatric-onset disabilities are at a greater risk for PPHs. Providing better access to preventive care and health-promoting services, especially for respiratory and urinary outcomes, may reduce PPH risk among this patient population.

MicroRNA-21-5p agomir inhibits apoptosis of oligodendrocyte precursor cell and attenuates white matter injury in neonatal rats

BACKGROUND AND RESEARCH QUESTION/HYPOTHESIS

Excessive oligodendrocyte precursor cell (OPC) apoptosis occurs during intrauterine infection-induced white matter injury (WMI) in premature infants, preventing excessive apoptosis of OPCs is one of the mechanisms protecting WMI. Micro-RNA-21-5p (miR-21-5p) mediating anti-apoptotic activity was observed in other diseases. Therefore, the aim of this study was to determine whether miR-21-5p protects against WMI by modulating phosphatase and tensin homolog deleted on chromosome 10/phosphatidylinositol-3-kinase/protein kinase B (PTEN/PI3K/Akt) signaling pathway.

METHODS

A lipopolysaccharide (LPS)-induced neonatal Sprague-Dawley (SD) rat model of preterm WMI was established. To explore the effect of miR-21-5p on WMI, we intraventricularly injected miR-21-5p agomir and miR-21-5p antagomir to activate or inhibit endogenous miR-21-5p. Immunofluorescent labelling of myelin basic protein, immunohistochemical labelling of 2',3'-cyclic-nucleotide 3'-phosphodiesterase (CNPase), and terminal deoxynucleotidyl transferase dUTP nick end labelling assays were conducted to observe pathological white matter changes. The antibody of anti-oligodendrocyte marker 4 (O4) was used to specifically recognise OPCs. The expressions of miR-21-5p and PTEN mRNA in the brain were detected with quantitative real-time polymerase chain reaction (qRT-PCR). PTEN, Akt, and phosphorylated Akt (p-Akt) protein levels were assayed with western blotting, and apoptotic proteins associated with PI3K/Akt signalling were quantified.

RESULTS

Intense white matter dysplasia and excessive OPC apoptosis were observed in the brains of rats with WMI. When the miR-21-5p agonist miR-21-5p agomir was used in the WMI group, apoptosis of OPCs was significantly reduced, and myelin maturation increased. MiR-21-5p agomir relieved WMI. MiR-21-5p agomir inhibited the mRNA and protein expression of PTEN, increased p-Akt phosphorylation, and decreased the expression and activation of related apoptotic proteins.On the other hand, the administration of miR-21-5p specific blocker, miR-21-5p antagomir, reduced the level of p-AKT, increased OPC apoptosis, and worsened WMI.

INTERPRETATION

Our findings revealed that miR-21-5p agomir had anti-OPC over-apoptotic effects and enhanced myelin development in WMI by modulating the PTEN/Akt signaling pathway.

The economic burden of congenital Zika Syndrome in Brazil: an overview at 5 years and 10 years

Background

The aim of this paper is to estimate the economic burden of children with congenital Zika Syndrome (CZS) in Brazil over 5–10 years.

Methods

We conducted a modelling study based on data collected in a case–control study in Brazil, including children with CZS (cases) and typically developing children (controls), born in 2015 and 2016. In total, 484 participants were recruited in two sites, Recife and Rio de Janeiro. Social and economic information was collected in a survey from the carers of cases and controls, and detailed healthcare utilisation was recorded for each child in the Rio de Janeiro cohort prospectively in a database. We used this information to estimate the cost per child with severe, moderate and no CZS and incremental cost per child with severe and moderate versus no CZS from a disaggregated societal perspective. These estimates were incorporated into an economic burden model to estimate the incremental burden of the CZS epidemic in Brazil over 5 years and 10 years.

Findings

The societal cost per child with severe CZS was US$50 523 to 10 years of age (born in 2015 and 2016), substantially higher than the costs for moderate CZS (US$29 283) and without CZS (US$12 331). The incremental economic burden of severe versus no CZS in Brazil over 10 years was US$69.4 million from the household and US$129.0 million from the government perspective. For moderate CZS, these figures amounted to US$204.1 million and US$86.6 million. Over 10 years, 97% of the total societal economic cost of severe CZS is borne by the government, but only 46% for moderate CZS.

Interpretation

The economic burden of CZS is high at the household, provider and government levels. The compensatory government payments helped to alleviate some of the additional costs incurred by families with a child qualifying for the disability benefits, and could be scaled to include the children with moderate CZS.

The safety and efficacy of umbilical cord blood mononuclear cells in individuals with spastic cerebral palsy: a randomized double-blind sham-controlled clinical trial

INTRODUCTION

The current multi-center, randomized, double-blind study was conducted among children with cerebral palsy (CP) to assess the safety and efficacy of umbilical cord blood mononuclear cell (UCB-MNC). We performed the diffusion tensor imaging to assess the changes in the white matter structure.

METHODS

Males and females aged 4 to 14 years old with spastic CP were included. Eligible participants were allocated in 4:1 ratio to be in the experimental or control groups; respectively. Individuals who were assigned in UCB-MNC group were tested for human leukocyte antigen (HLA) and fully-matched individuals were treated with UCB-MNCs. A single dose (5 × 106 /kg) UCB-MNCs were administered via intrathecal route in experimental group. The changes in gross motor function measure (GMFM)-66 from baseline to one year after treatment were the primary endpoints. The mean changes in modified Ashworth scale (MAS), pediatric evaluation of disability inventory (PEDI), and CP quality of life (CP-QoL) were also evaluated and compared between groups. The mean changes in fractional anisotropy (FA) and mean diffusivity (MD) of corticospinal tract (CST) and posterior thalamic radiation (PTR) were the secondary endpoints. Adverse events were safety endpoint.

RESULTS

There were 72 included individuals (36 cases in each group). The mean GMFM-66 scores increased in experimental group; compared to baseline (+ 9.62; 95%CI: 6.75, 12.49) and control arm (β: 7.10; 95%CI: 2.08, 12.76; Cohen's d: 0.62) and mean MAS reduced in individuals treated with UCB-MNCs compared to the baseline (-0.87; 95%CI: -1.2, -0.54) and control group (β: -0.58; 95%CI: -1.18, -0.11; Cohen's d: 0.36). The mean PEDI scores and mean CP-QoL scores in two domains were higher in the experimental group compared to the control. The imaging data indicated that mean FA increased and MD decreased in participants of UCB-MNC group indicating improvements in white matter structure. Lower back pain, headaches, and irritability were the most common adverse events within 24 h of treatment that were related to lumbar puncture. No side effects were observed during follow-up.

CONCLUSIONS

This trial showed that intrathecal injection of UCB-MNCs were safe and effective in children with CP.

The Economic Burden and Determinant Factors of Parents/Caregivers of Children with Cerebral Palsy in Malaysia: A Mixed Methods Study

The economic burden is a major concern for parents/caregivers of children with cerebral palsy (CP). This study used the sequential explanatory mixed-method approach to explorethe economic burden on parents/caregivers with a CP child in Malaysia and the factors associated with the economic burden. The study period spanned April 2020 and December 2020. A total of 106 questionnaire respondents were selected for the quantitative part, and 15 were interviewed to obtain qualitative input. A retrospective costing analysis was conducted based on the cost data obtained from the questionnaire. The majority of the children were GrossMotor Function Classification System (GMFCS) Level 5 (71%), quadriplegic (63%), and aged >4 years (90%). The estimated annual median total economic burden on the parents/caregivers per child in 2020 was RM52,540.00 (~USD12,515.03), with indirect cost being the greatest cost (RM28,800.00, ~USD6860.16), followed by developmental cost (RM16,200.00, ~USD3858.84), direct healthcare cost (RM4540.00, ~USD1081.43) and direct non-healthcare cost (RM3000.00, ~USD714.60). The annual household income was identified as a significant determinant factor (p=0.019, 95% CI: 0.04, 0.40) of the economic burden. The participants’ responses during the in-depth interview in the qualitative part of the study supported the premise that socioeconomic factors play a substantial role in determining the total economic burden. Our findings may aid local policymakers when planning the greater provision of support to the affected families in the future, especially for the parents/caregivers of children with CP, who are facing socioeconomic challenges.

Effect of total number of pulses of radial extracorporeal shock wave therapy (rESWT) on hamstring muscle spasticity in children with spastic type cerebral palsy: A randomized clinical trial

PURPOSE

To evaluate the efficacy and safety of radial extracorporeal shock wave therapy (rESWT) according to total number of pulses on hamstring muscle spasticity in children with spastic type cerebral palsy (CP).

METHODS

This study is a randomized controlled trial consisting of thirteen patients with spastic CP, 9 males and 4 females, aged 5 to 14 years (mean age 9.2). Twenty-five spastic hamstring muscles were divided in four groups. Group I: 500 pulses, Group II: 1,000 pulses, Group III: 1,500 pulses, and Group IV: 2,000 pulses. Australian Spasticity Assessment Scale (ASAS) was measured at four different time points (pre-ESWT, post-ESWT, 2 weeks post-ESWT, and 4 weeks post-ESWT).

RESULTS

All four groups showed improvement in ASAS relative to pre-treatment, although only significant in Group III (1,500 pulses). There were no statistically significant differences in ASAS between all four groups in pre-ESWT [|2(2) = 3.907, p = 0.272], immediately post-ESWT [|2(2) = 1.250, p = 0.741], 2 weeks post-ESWT vs pre-ESWT [|2(2) = 3.367, p = 0.338], and 4 weeks post-ESWT vs pre-ESWT [|2(2) = 1.566, p = 0.667].

CONCLUSION

The effect of rESWT on spastic hamstring in children with spastic CP is not dependent on the number of pulses.

Electronic health record and patterns of care for children with cerebral palsy

AIM

To characterize the patterns of care of children with cerebral palsy (CP) in a tertiary healthcare system.

METHOD

Electronic health record data from 2009 to 2019 were extracted for children with CP. Machine learning hierarchical clustering was used to identify clusters of care. The ratio of in-person to care coordination visits was calculated for each specialty.

RESULTS

The sample included 6369 children with CP (55.7% males, 44.3% females, 76.2% white, 94.7% non-Hispanic; with a mean age of 8y 2mo [SD 5y 10mo; range 0-21y; median 7y 1mo]) at the time of diagnosis. A total of 3.7 million in-person visits and care coordination notes were identified across 34 specialties. The duration of care averaged 5 years 5 months with five specialty interactions and 21.8 in-person visits per year per child. Seven clusters of care were identified, including: musculoskeletal and function; neurological; high-frequency/urgent care services; procedures; comorbid diagnoses; development and behavioral; and primary care. Network analysis showed shared membership among several clusters.

INTERPRETATION

Coordination of care is a central element for children with CP. Medical informatics, machine learning, and big data approaches provide unique insights into care delivery to inform approaches to improve outcomes for children with CP. What this paper adds Seven primary clusters of care were identified: musculoskeletal and function; neurological; high-frequency/urgent care services; procedures; comorbid diagnoses; development and behavioral; and primary care. The in-person to care coordination visit ratio was 1:5 overall for healthcare encounters. Most interactions with care teams occur outside of in-person visits. The ratio of in-person to care coordination activities differ by specialty.

Immunological effects of cerebral palsy and rehabilitation exercises in children

Cerebral palsy (CP) is a group of motor disorders caused by non-progressive lesions of the premature brain with lifelong pathophysiological consequences that include dysregulation of innate immunity. Persistent inflammation with increased levels of circulating pro-inflammatory tumor necrosis factor alpha (TNF-a) is negatively associated with rehabilitation outcome in children with CP. Because of the crosstalk between innate and adaptive immunity, we investigated the effect of CP and rehabilitation exercises on the adaptive immune system in children with CP by measuring the levels of CD3⁺, CD4⁺, CD8⁺ Т-cells, and CD22⁺ B-cells and the levels of immunoglobulins. Children with CP had higher levels of CD3⁺, CD4⁺, CD8⁺ Т-cells, and CD22⁺ B-cells compared to healthy children, and the rehabilitation exercise programs produced better outcomes in terms of increased gains in motor function at an earlier age. Rehabilitation exercises performed over a month resulted in significantly decreased levels of IgA in serum and reduced numbers of B-lymphocytes and reduced IgM levels. Our study suggests that rehabilitation programs with a focus on neuroplasticity and physical exercises in children with CP can reduce both cellular and humoral immune responses.

•

Children with CP demonstrate increased levels of T and B cells.

•

Rehabilitation exercises helped balance immune responses.

Effectiveness of Botulinum Toxin A Injection in Managing Mobility-Related Outcomes in Adult Patients With Cerebral Palsy: Systematic Review

PURPOSE

Intramuscular botulinum toxin A (BTX-A) is used in the management of focal spasticity in cerebral palsy (CP). The aim was to conduct a systematic review to assess current literature on the use of BTX-A in the management of mobility-related outcomes among adult persons with spastic CP.

METHODS

All studies reporting on the use of BTX-A in the management of spastic CP among adult persons were identified by searching the following electronic databases: PubMed, CINAHL, the Cochrane Library, and EMBASE.

RESULTS

Six studies were included in the review. Most studies were conducted in mixed patient groups comprising patients with movement disorders, traumatic brain injury, CP, and other disorders requiring therapy for spasticity. BTX-A was shown to be effective in improving spasticity-related outcomes among persons with CP, but mixed results were shown for functional outcomes.

CONCLUSIONS

More studies are required on exclusive CP cohorts using recommended and currently used scales, incorporating quality of life and patient satisfaction scales. Results from long-term follow-up studies will be valuable for better evaluation of the effectiveness of BTX-A in the management of spasticity-related outcomes among adult persons with CP.

Diagnosing newborns with suspected mitochondrial disorders: an economic evaluation comparing early exome sequencing to current typical care

PURPOSE

To determine the value of early exome sequencing (eES) relative to the current typical care (TC) in the diagnosis of newborns with suspected severe mitochondrial disorders (MitD).

METHODS

We used a decision tree-Markov hybrid to model neonatal intensive care unit (NICU)-related outcomes and costs, lifetime costs and quality-adjusted life-years among patients with MitD. Probabilities, costs, and utilities were populated using published literature, expert opinion, and the Pediatric Health Information System database. Incremental cost-effectiveness ratios (ICER) and net monetary benefits (NMB) were calculated from lifetime costs and quality-adjusted life-years for singleton and trio eES, and TC. Robustness was assessed using univariate and probabilistic sensitivity analyses (PSA). Scenario analyses were also conducted.

RESULTS

Findings indicate trio eES is a cost-minimizing and cost-effective alternative to current TC. Diagnostic probabilities and NICU length-of-stay were the most sensitive model parameters. Base case analysis demonstrates trio eES has the highest incremental NMB, and PSA demonstrates trio eES had the highest likelihood of being cost-effective at a willingness-to-pay (WTP) of $200,000 relative to TC, singleton eES, and no ES.

CONCLUSION

Trio and singleton eES are cost-effective and cost-minimizing alternatives to current TC in diagnosing newborns suspected of having a severe MitD.

Microsurgical DREZotomy in Spastic Cerebral Palsy: Poor Man's Baclofen Pump

BACKGROUND

Using an intrathecal baclofen (ITB) pump for severe refractory spastic cerebral palsy is not a viable option in resource-constraint settings. Therefore authors assessed the role of microsurgical dorsal root entry zone-otomy (MDT) as an alternative for patients in whom the circumstances did not allow ITB pump placement.

METHODS

A prospective clinical study was conducted from August 2016 to July 2020. All patients of spastic cerebral palsy (with III-IV Ashworth grade) who underwent MDT were included. Preoperative and postoperative Ashworth grade and Gross Motor Function Classification System level were assessed along with any change in power, sensation, and bladder functions postoperatively. At last follow-up, the patients' main care providers were asked to rate the effect of surgery (on scale of 0-5) on ease of providing care related to 6 activities of daily living.

RESULTS

Seven patients (5 males, 2 females) of spastic cerebral palsy with an age range of 6-21 years underwent MDT over the study period. Six patients had spastic diplegia, and 1 had spastic hemiplegia. Preoperative Ashworth grade in all patients was 3-4 in various involved muscle groups. Four patients with spastic diplegia underwent MDT at L3-S1 level bilaterally, 2 patients with spastic diplegia and spastic bladder underwent MDT at L3-S4 level bilaterally, and 1 patient with right-sided spastic hemiplegia underwent MDT at C5-T1 level and L3-S1 level on the right side. Postoperative Ashworth grade in all patients improved to 0-1. The improvement in mean Ashworth grade was from 3.14 ± 0.378 preoperatively to 0.29 ± 0.488 (P value = 0.000). Most care providers reported improvement in their ability to do physiotherapy, position, clothe, ambulate, and maintain patient's personal hygiene. Care providers of 6 patients reported that they were likely to recommend MDT to another similar patient.

CONCLUSIONS

MDT is a cost-effective tool in deceasing limb spasticity in spastic cerebral palsy, especially for those who cannot afford ITB placement.

Pain and Communication in Children with Cerebral Palsy: Influence on Parents' Perception of Family Impact and Healthcare Satisfaction

Cerebral palsy (CP) is an impacting chronic condition. Concomitant comorbidities such as pain and speech inability may further affect parents’ perception of the pathology impact in the family quality of life and the provided care. The objective of this cross-sectional descriptive correlational study was to compare parental reports on family impact and healthcare satisfaction in children with CP with and without chronic pain and with and without speech ability. Parents of 59 children with CP (age range = 4–18 years) completed several questions about pain and speech ability and two modules of the Pediatric Quality of Life Measurement Model: The PedsQLTM 2.0 Family Impact Module and the PedsQLTM Healthcare Satisfaction Generic Module. Our findings revealed that children’s pain slightly impacted family physical health, social health and worry. In children without pain, speech inability increased the perceived health impact. Parents’ healthcare satisfaction was barely affected by pain or speech inability, both increasing parents’ satisfaction in the professional technical skills and inclusion of family domains on the care plan. In conclusion, pain and speech inability in children with CP can impact family health but not healthcare satisfaction. Regular assessment and intervention in family health is essential for the design of family-centred programs for children with CP.

Protocol for a cost-utility analysis of neurostimulation and intensive camp-based therapy for children with perinatal stroke and hemiparesis based on a multicentre clinical trial

INTRODUCTION

Perinatal stroke leads to cerebral palsy (CP) and lifelong disability for thousands of Canadian children. Hemiparesis, referring to impaired functionality in one side of the body, is a common complication of perinatal stroke. Standard long-term care for hemiparetic CP focuses on rehabilitation therapies. Early research suggests that patients with hemiparesis may benefit from adjunctive neuromodulation treatments such as transcranial direct current stimulation (tDCS). tDCS uses electric current to stimulate targeted areas of the brain non-invasively, potentially enhancing the effects of motor learning therapies. This protocol describes an economic evaluation to be conducted alongside a randomised controlled trial (RCT) to assess the incremental cost of tDCS added to a camp-based therapy compared with camp-based therapy alone per quality-adjusted life year (QALY) gained in children with hemiparetic CP.

METHODS AND ANALYSIS

The Stimulation for Perinatal Stroke Optimising Recovery Trajectories (SPORT) trial is a multicentre RCT evaluating tDCS added to a 2-week camp-based therapy for children aged 6-18 years with perinatal ischaemic stroke and disabling hemiparetic CP affecting the upper limb. Outcomes are assessed at baseline, 1 week, 2 months and 6 months following intervention. Cost and quality of life data are collected at baseline and 6 months and results will be used to conduct a cost-utility analysis (CUA). The evaluation will be conducted from the perspectives of the public healthcare system and society. The CUA will be conducted over a 6-month time horizon.

ETHICS AND DISSEMINATION

Ethical approval for the SPORT trial and the associated economic evaluation has been given by the research ethics boards at each of the study sites. The findings of the economic evaluation will be submitted for publication in a peer reviewed academic journal and submitted for presentation at conference.

Umbilical cord blood cells for the treatment of preterm white matter injury: Potential effects and treatment options

Preterm birth is a global public health problem. A large number of preterm infants survive with preterm white matter injury (PWMI), which leads to neurological deficits, and has multifaceted etiology, clinical course, monitoring, and outcomes. The principal upstream insults leading to PWMI initiation are hypoxia-ischemia and infection and/or inflammation and the key target cells are late oligodendrocyte precursor cells. Current PWMI treatments are mainly supportive, and thus have little effect in terms of protecting the immature brain or repairing injury to improve long-term outcomes. Umbilical cord blood (UCB) cells comprise abundant immunomodulatory and stem cells, which have the potential to reduce brain injury, mainly due to anti-inflammatory and immunomodulatory mechanisms, and also through their release of neurotrophic or growth factors to promote endogenous neurogenesis. In this review, we briefly summarize PWMI pathogenesis and pathophysiology, and the specific properties of different cell types in UCB. We further explore the potential mechanism by which UCB can be used to treat PWMI, and discuss the advantages of and potential issues related to UCB cell therapy. Finally, we suggest potential future studies of UCB cell therapy in preterm infants.

[Caregiver burden in patients with moderate-severe cerebral palsy. The influence of nutritional status]

INTRODUCTION

Patients with moderate-severe cerebral palsy require the support of their caregivers to carry out the activities of daily living (ADLs).

OBJECTIVES

To describe the comorbidities, need for care in children with cerebral palsy and to analyse the influence of the degree of motor involvement, nutritional status and other neurological disorders.

METHODS

Cross-sectional and observational study. Patients with cerebral palsy degrees III-IV-V according to the Gross Motor Function Classification System (GMFCS) have been studied. A record of comorbidities has been made and body composition has been studied using anthropometry and bioimpedance. In addition, a caregiver burden survey on ADLs has been carried out (10 items on the different actions: hygiene, clothing, transfers, sleeping and feeding). Which variables have the greatest influence on the perception of difficulty in performing ADLs have been studied.

RESULTS

A total of 69 patients (50.7% women, mean age 10.46 ± 0.4 years) were analysed, with GMFCS grades: grade III 36.2% (N=25), grade IV 29.0% (N=20), grade V 34.8% (N=24). A relationship was found between the caregiver burden score and GMFCS grade (P=0.003) and intellectual disability (P<0.001). However, regardless of the degree of GMFCS and intellectual disability, there is greater difficulty in performing ADLs in relation to lower values in weight (Z-score) (P=0.028), fat mass (kg) (P=0.035), fat mass (%) (P=0.094), body mass index (Z-score) (P=0.086).

CONCLUSIONS

In addition to the degree of clinical impairment, nutritional status is a factor that influences the caregiver's difficulty in performing the ADLs in cerebral palsy patients on which we can act to improve this problem.

Minimally Invasive SPML Surgery for Children with Cerebral Palsy: Program Development

Improvements in surgical and rehabilitation care are critical to lessen the burden of cerebral palsy (CP), the most common cause of severe physical disability in childhood. The selective percutaneous myofascial lengthening (SPML) surgical procedure is a minimally invasive method designed to improve ambulation by lengthening contracted musculoskeletal tissues. Information on surgical procedures, efficacy, and safety of SPML for children with CP is lacking. Phase 1 of our research is a “proof-of-principle” study for multisite SPML to improve functional mobility of children with CP, and Phase 2 assesses safety, reoperation rates, and efficacy over time in subsequent patient series. Phase 1 was a repeated measurement case series study of 17 children (mean age 7.6 years). One physical therapist, blinded to the surgeon's measurements, measured bilateral knee and ankle motion before and after SPML procedures, using video recordings of a standardized gait path. Functional Mobility Scale (FMS) 5, 50, and 500 outcomes were taken pre- and postoperatively and via telephone follow-up. In Phase 2, multisite SPLM surgeries were implemented in larger successive cohorts from 2006 to 2017. Complications, reoperation rates, and efficacy were retrospectively analyzed. Phase 1 results showed improvement in the children's knee and ankle motion while ambulating and improved FMS 5, 50, and 500 outcomes postoperatively (mean, 6.3 months). At second follow-up (mean 33.3 months), FMS 500 scores continued improvement, while FMS 5 and FMS 50 scores maintained. During Phase 2, the complication rate was 2.4%, and reoperation rates (including reoperations due to maturation) were between 8% and 13%. Improvements to correct ankle equinus were recorded in 498 cases. In conclusion, in a specialized center, single-event, multilevel SPML surgeries of children with CP safely improved ambulatory knee and ankle angle motion and daily mobility outcomes. Future educational studies of training needs for surgeons new to the approach are needed.

A Case-Control Study of Essential and Toxic Trace Elements and Minerals in Hair of 0-4-Year-Old Children with Cerebral Palsy

The objective of the present study was to assess hair essential and toxic trace elements and minerals in children with cerebral palsy in relation to age of the examinees. A total of 70 children with cerebral palsy and 70 healthy controls aged 0-4 years old were enrolled in the present study. The examined children were also divided into two age groups of those younger and older than 2 years old. Hair trace element content was assessed using ICP-MS at NexION 300D (PerkinElmer, USA). The obtained data demonstrate that hair boron was more than 2-fold lower in CP children as compared with the control group. At the same time, hair Na, Se, and V levels were 21%, 12%, and 20% lower when compared with healthy controls, respectively. It is also notable that a 9% and 28% decrease in hair Fe and Li levels respectively were nearly significant. The observed alterations were more profound in a younger group of patients. No significant group difference in hair toxic metal and metalloid levels was observed between the general cohorts of children with and without CP. In regression models, only hair Al and Ca contents were significantly associated with the presence of cerebral palsy, whereas hair Mg, Na, Ni, and Se levels were characterized as significant negative predictors. The observed alteration in trace element metabolism may also provide an additional link between cerebral palsy, psychomotor delay, and certain diseases, including diabetes, epilepsy, and osteoporosis. However, further studies using other substrates (blood, urine) or biomarkers are required.

Advances in cerebral palsy biomarkers

Cerebral palsy (CP), defined as a group of nonprogressive disorders of movement and posture, is the most common cause of severe neurodisability in children. The prevalence of CP is the same across the globe, affecting approximately 17 million people worldwide. Cerebral Palsy is an umbrella term used to describe the disease due to its inherent heterogeneity. For instance, CP has multiple (1) causes; (2) clinical types; (3) patterns of neuropathology on brain imaging and (4) it's associated with several developmental pathologies such as intellectual disability, autism, epilepsy, and visual impairment. Understanding its physiopathology is crucial to developing protective strategies. Despite its importance, there is still insufficient progress in the areas of CP prediction, early diagnosis, treatment, and prevention. Herein we describe the current risk factors and biomarkers used for the diagnosis and prediction of CP. With the advancement in biomarker discovery, we predict that our understanding of the etiopathophysiology of CP will also increase, lending to more opportunities for developing novel treatments and prognosis.

Continuity of Care Is Associated with Medical Costs and Inpatient Days in Children with Cerebral Palsy

Background: Children with cerebral palsy (CP) place a considerable burden on medical costs and add to an increased number of inpatient days in Taiwan. Continuity of care (COC) has not been investigated in this population thus far. Materials and Methods: We designed a retrospective population-based cohort study using Taiwan’s National Health Insurance Research Database. Patients aged 0 to 18 years with CP catastrophic illness certificates were enrolled. We investigated the association of COC index (COCI) with medical costs and inpatient days. We also investigated the possible clinical characteristics affecting the outcome. Results: Over five years, children with CP with low COCI levels had higher medical costs and more inpatient days than did those with high COCI levels. Younger age at CP diagnosis, more inpatient visits one year before obtaining a catastrophic illness certificate, pneumonia, and nasogastric tube use increased medical expenses and length of hospital stay. Conclusions: Improving COC reduces medical costs and the number of inpatient days in children with CP. Certain characteristics also influence these outcomes.

A Platform for Rehabilitation of Finger Individuation in Children with Hemiplegic Cerebral Palsy

The brain injury that results in cerebral palsy CP may adversely affect fine motor control of the hand. The degradation of manual dexterity in the fingers profoundly impacts overall functionality of the upper limb, yet research efforts to facilitate rehabilitation of finger individuation in children with CP have been limited. This study describes the development of an integrated hardware and software platform for training and evaluating finger individuation. A pneumatically actuated glove provides extension assistance or flexion resistance independently to each digit in concert with playing a virtual reality keyboard. This setup enables intensive and efficient practice of fine motor control of either or both hands. Bimanual training options range from mirror movements to fully independent motions and rhythms in each hand, thereby enabling maintenance of the proper level of challenge. Additionally, an instrument was created to provide assessment of individuated fingertip force generation in order to evaluate effectiveness of the training. Preliminary data were obtained from children both with and without CP using this tool.

Adult dyskinetic cerebral palsy: Upper limb movement and muscle function

AIM

The aim of this study was to characterize upper limb motor function during a comparative analysis of electromyographic and upper limb movement analysis during drinking between healthy adults and individuals with DCP.

METHOD

Fifteen healthy individuals (CG) and fifteen individuals with DCP (DG) participated in the study. Upper limb function was analyzed during drinking and consisted of a task divided into three phases: the going, the adjustment, and the return.

RESULTS

Electromyographic analysis revealed a lower activity of the anterior deltoid, posterior deltoid, and biceps brachii muscles in the DG. When comparing the interactions between groups and phases, only biceps brachii shower lower muscle activity during going and adjustment phases. The DG presented a smaller range of motion (ROM) for the shoulder, elbow, forearm and wrist movements. An interaction between groups and phases showed smaller ROM for the flexion and internal rotation of the shoulder, elbow flexion, forearm pronation, and ulnar deviation in the return phase compared to CG.

INTERPRETATION

The results may contribute positively to the quantification of the level of motor impairment and may be used as a reference for the development of therapeutic interventions for patients with DCP.

Flaunting our assets. Making the most of the Nordic registry goldmine: Cerebral palsy as an example

Aims:To describe the early experiences of a Nordic multidisciplinary cerebral palsy (CP) registry research program combining data from national medical quality registries, follow-up programs and cohort data, in addition to data from other national registries; to explore the scientific and practical uses of such research, and provide recommendations for facilitating similar work in the future. Methods: The work was divided into three themes: medical outcomes, social and public health outcomes, and health economics; and three cross-cutting teams: a reference team, a challenge team, and a communication and dissemination team. Initially each country will perform domestic research, and in the second stage data will be merged across all Nordic countries. Data from national registries with vital statistics, education and work, social benefits, and healthcare will be used. Comparisons will be matched for both the individuals with CP and their parents. Results: Initial work has been done on agreeing which variables to request from the respective agencies and planning the correct procedures and steps required to acquire the data. As of 2018, Sweden, Norway, and Finland have received approved ethics board applications. Iceland and Denmark are waiting for their approvals. A webpage and a platform for internal communication have been created. Conclusions: Nordic register research has great potential. Linking national CP quality registries and follow-up programs with other large national registries holds particular promise because problems identified through research can be applied at a population level. It is imperative that ethical clearance and data delivery processes are streamlined and transparent, and that data variables are measured the same way in the different countries.

Optimal Management of Undescended Testis in Boys with Cerebral Palsy. A Debate

Cerebral palsy is a rare condition following injury of the developing brain and including nonprogressive neurological disorders, spasticity, intellectual impairment and others. Boys with cerebral palsy have a high incidence of undescended testis. Although the motives for treatment (infertility, cancer prevention, psychological aspects, testicular torsion) are not different in boys without neurological impairment, the decision-making process in boys with cerebral palsy is very difficult. Besides medical and surgical arguments the discussion involves challenging ethical issues.
