Variation in cerebral palsy profile by socio-economic status

A qualitative study investigating the experiences of unmet social needs for children with cerebral palsy and their families: perspectives of parents and clinicians

PURPOSE

To explore (i) the impact of unmet social needs on children with cerebral palsy and their families; (ii) enablers-, and (iii) barriers to addressing unmet social needs.

MATERIAL AND METHODS

Eligible participants attended or worked at one of the three Paediatric Rehabilitation Departments including: children with a diagnosis of cerebral palsy; parents/carers; and clinicians. One-on-one interviews were conducted with parents/carers and focus groups with clinicians. Interview and focus group transcripts were deductively thematically analysed according to the social model of disability.

RESULTS

A total of 44 participants (8 parents and 36 clinicians) took part. No children consented to participate. Analysis of the qualitative data identified four main themes and 14 sub-themes. The main themes were: Unmet social needs are pervasive; An inequitable health system with no roadmap; Everyone suffers as a result of unmet social needs; and It takes a village to raise a child.

CONCLUSION

Unmet social needs have profound impacts on families. The experiences of unmet social needs are intensified by the extra complexities of raising a child with disability. Societal barriers including inequitable systems and the fragmented services are barriers impeding on families receiving support and ultimately limiting their wellbeing.

Association of Gestational Age at Birth and Changes on MRI With Prevalence and Spectrum of Comorbidities in Children With Cerebral Palsy

BACKGROUND AND OBJECTIVES

For individuals with cerebral palsy (CP) and caregivers, comorbidities may be a greater challenge than neuromotor impairment. Clinicians may make assumptions regarding risk of comorbidities based simply on term vs preterm birth, but this has not been well examined. To better understand factors affecting comorbidity pattern, we investigated the relationship between gestational age (GA) and imaging pattern on the presence of specific comorbidities.

METHODS

This is a cross-sectional study of data extracted from the Canadian Cerebral Palsy Registry of children with CP. Multivariable analysis was used to evaluate the relationship between brain injury, GA, and comorbidities. Comorbidities included in the analysis were communication, cognitive, visual, and auditory impairment, seizures in the past year, and gavage feeding. Each comorbidity was assessed as a separate nonexclusive outcome, with GA, MRI pattern, birth weight, postneonatal insult, 5-minute Apgar score, and male sex considered as potential modifiers.

RESULTS

The only comorbidity affected by GA on multivariable analysis was seizures within the past year that were more prevalent in term children (odds ratio [OR] 1.1 95% CI 1.0-1.2) and was also affected by Apgar score (OR 0.9 95% CI 0.85-0.94), but not MRI pattern. MRI pattern appeared important for communication impairment (deep gray OR 4.2 95% CI 1.8-10.0; total brain injury OR 8.5, 95% CI 3.2-22.6; malformation OR 2.7, 95% CI 1.3-5.7) and cognitive impairment (deep gray OR 5.6, 95% CI 2.4-13.2; total brain injury OR 10.1, 95% CI 4.0-25.3; malformation OR 3.3, 95% CI 1.6-6.8; watershed OR 3.6, 95% CI 1.4-8.9). Focal injury compared with normal MRI was associated with reduced odds of visual impairment (OR 0.24, 95% CI 0.12-0.48), auditory impairment (OR 0.2195% CI 0.10-0.46) and communication impairment (OR 0.46, 95% CI 0.26-0.82), and overall number of comorbidities (coefficient -0.73, 95% CI -1.2 to -0.31). The number of comorbidities was increased by total brain injury pattern (coefficient 0.65, 95% CI 0.15-1.13) and reduced by focal brain injury (coefficient -0.73, 95% CI -1.2 to -0.31) and increasing 5-minute Apgar score (coefficient -0.11, 95% CI -0.16 to -0.07).

DISCUSSION

In those with brain injuries sufficient to cause CP, development of additional comorbidities is less affected by GA at birth and more related to the underlying cause of CP as reflected by MRI patterns.

Sociodemographic and clinical indicators of children and young people with cerebral palsy and reported unmet social needs

AIM

To determine the frequency, type, clinical, and sociodemographic associations of unmet social needs in children with cerebral palsy (CP).

METHOD

We conducted a cross-sectional study of parents and carers of children with CP attending a specialist hospital clinic between July and September 2022. Unmet social needs were self-identified using a survey, guided by the WE CARE survey instrument and adapted to the local context. Sociodemographic and clinical data were obtained from medical records. We performed descriptive analysis of participants' unmet social needs, sociodemographic factors, and clinical factors, and examined for associations using a χ2 test and logistic regression.

RESULTS

A total of 105 parents and carers completed the survey. Of these, 68 (64.8%) reported one or more unmet social need, with 24 (22.9%) reporting three or more unmet needs. A higher number (three or more) of unmet needs was associated with Gross Motor Function Classification System levels IV and V (odds ratio [OR] = 3.77, 95% confidence interval [CI] = 1.44-9.86) and intellectual disability (OR = 4.63, 95% CI = 1.61-13.31), but were not significant when corrected for neighbourhood socioeconomic disadvantage. The greatest socioeconomic disadvantage was associated with housing concerns (p = 0.002), food (p = 0.026), and financial insecurity (p = 0.02).

INTERPRETATION

Unmet social needs are experienced by most families of children with CP. This study highlights the importance of systematic pathways to identify and address unmet social needs.

Development of a new social prescribing intervention for families of children with cerebral palsy

AIM

To co-design a social prescribing intervention (the EPIC-CP programme: Equitable Pathways and Integrated Care in Cerebral Palsy) with children with cerebral palsy (CP), their families, and clinicians to address unmet social needs.

METHOD

The study was conducted (August 2021 to March 2023) at the paediatric rehabilitation departments of the three tertiary paediatric hospitals in New South Wales, Australia. Eligible participants attended or worked at one of the departments, including children with CP, parents/caregivers, and clinicians. Mixed-methods co-design was used in intervention co-production and prototyping. The project was overseen by research advisors with lived experience of CP.

RESULTS

More than 200 participants contributed to the co-design research. Families experienced a substantial burden of unmet social needs. Co-designed interventions involved systematic identification of unmet social needs with (1) targeted community resources and (2) engagement with a 'community linker' who supported children/young people and their families to access health, education, and social services that matched their identified needs and preferences. Research participants co-developed the programme logic model and prototype. This was piloted in research action cycles and iteratively refined until consensus was achieved.

INTERPRETATION

We co-designed a social prescribing programme responsive to the needs of its end-users and purposefully developed to be embedded in the Australian health setting. A pilot randomized controlled trial will further evaluate this intervention.

EPIC-CP pilot trial study protocol: a multicentre, randomised controlled trial investigating the feasibility and acceptability of social prescribing for Australian children with cerebral palsy

INTRODUCTION

The social determinants of health contribute to poorer health outcomes for children with cerebral palsy (CP) and are barriers to families accessing health services. At an individual level, social determinants of health are experienced as unmet social needs, for example, unsafe housing conditions. There is emerging evidence that clinical pathways for the systematic identification and referral to services for unmet social needs can support families to address these needs. These clinical pathways have not been implemented for children with CP. The objectives are to investigate the feasibility and acceptability of two co-designed social needs clinical pathways for parents/caregivers of children with CP-social prescribing (ie, Community Linker plus resource pack) compared with resource pack only.

METHODS AND ANALYSIS

This pilot randomised controlled trial will run at the three tertiary paediatric rehabilitation services in New South Wales, Australia. A total of 120 participants will be recruited, with randomisation stratified by study site. A survey tool will be used to identify families experiencing unmet social needs. Parents/caregivers who report one or more unmet social need/s and consent will be eligible. The active control group will receive a resource pack containing information on community services to support unmet social needs. The social prescribing intervention group will receive one-on-one Community Linker support, in addition to the resource pack. The survey tool, intervention, logic model, and resource pack were co-designed with patient families and their healthcare workers. Feasibility of the research design and the clinical pathways will be evaluated using the number/proportion of parents/caregivers who complete the survey tool, consent, engage with the intervention, and complete research measures. Acceptability will be evaluated using questionnaires and qualitative interviews.

ETHICS AND DISSEMINATION

Human research ethics approval was granted by the Sydney Children's Hospitals Network Human Research Ethics Committee (2022/ETH01688). Participants and stakeholders will receive updates and findings via regular communication channels including meetings, presentations, and publications.

Genetic pathways in cerebral palsy: a review of the implications for precision diagnosis and understanding disease mechanisms

ABSTRACT

Cerebral palsy is a diagnostic term utilized to describe a group of permanent disorders affecting movement and posture. Patients with cerebral palsy are often only capable of limited activity, resulting from non-progressive disturbances in the fetal or neonatal brain. These disturbances severely impact the child's daily life and impose a substantial economic burden on the family. Although cerebral palsy encompasses various brain injuries leading to similar clinical outcomes, the understanding of its etiological pathways remains incomplete owing to its complexity and heterogeneity. This review aims to summarize the current knowledge on the genetic factors influencing cerebral palsy development. It is now widely acknowledged that genetic mutations and alterations play a pivotal role in cerebral palsy development, which can be further influenced by environmental factors. Despite continuous research endeavors, the underlying factors contributing to cerebral palsy remain are still elusive. However, significant progress has been made in genetic research that has markedly enhanced our comprehension of the genetic factors underlying cerebral palsy development. Moreover, these genetic factors have been categorized based on the identified gene mutations in patients through clinical genotyping, including thrombosis, angiogenesis, mitochondrial and oxidative phosphorylation function, neuronal migration, and cellular autophagy. Furthermore, exploring targeted genotypes holds potential for precision treatment. In conclusion, advancements in genetic research have substantially improved our understanding of the genetic causes underlying cerebral palsy. These breakthroughs have the potential to pave the way for new treatments and therapies, consequently shaping the future of cerebral palsy research and its clinical management. The investigation of cerebral palsy genetics holds the potential to significantly advance treatments and management strategies. By elucidating the underlying cellular mechanisms, we can develop targeted interventions to optimize outcomes. A continued collaboration between researchers and clinicians is imperative to comprehensively unravel the intricate genetic etiology of cerebral palsy.

Social determinants of health for children with cerebral palsy and their families

Social determinants of health (SDH) influence health and social outcomes in positive and negative ways. Understanding the impact of SDH on children with cerebral palsy (CP) is essential to improve health equity, optimize health outcomes, and support children with CP and their families to thrive in society. In this narrative review, we summarize the landscape of SDH impacting children with CP and their families worldwide. In high-income countries, children from poorer neighbourhoods are more likely to have severe comorbidities, present with spastic bilateral CP, and report lower frequency of participation in community activities. In low- and middle-income countries, socioeconomic disadvantage is associated with increased risk of malnutrition, living in poorer housing conditions, not having access to proper sanitation, and living below the poverty line. Low maternal education is associated with increased likelihood of the child with CP experiencing increased severity of gross motor and bimanual functioning challenges, and poorer academic performance. Lower parental education is also associated with reduced child autonomy. On the other hand, higher parental income is a protective factor, associated with greater diversity of participation in day-to-day activities. A better physical environment and better social support are associated with higher participation in daily activities. Clinicians, researchers, and the community should be aware of these key challenges and opportunities. Then adopt a range of approaches that target adverse SDH/social needs and foster positive SDH in the clinical setting. WHAT THIS PAPER ADDS: Understanding how social determinants of health influence health and social outcomes is a critical step towards improving health equity and outcomes. Approaches are required that target the impact of adverse SDH on access to health care for children with cerebral palsy and that work towards ensuring equity of access for all.

Codesigning a social prescribing pathway to address the social determinant of health concerns of children with cerebral palsy and their families in Australia: a protocol for a mixed-methods formative research study

INTRODUCTION

Social determinants of health (SDH) are contributors to health inequities experienced by some children with cerebral palsy and pose barriers to families engaging with complex and fragmented healthcare systems. There is emerging evidence to support 'social prescribing' interventions that systematically identify SDH concerns and refer patients to non-medical social care support and services to address their needs. To date, social prescribing has not been trialled specifically for children with neurodevelopmental disabilities, including cerebral palsy, in Australia. This study aims to codesign a social prescribing programme to address SDH concerns of children with cerebral palsy and their families who attend one of the three tertiary paediatric rehabilitation services in New South Wales, Australia.

METHODS AND ANALYSIS

This is a qualitative multi-site study conducted at the three NSW paediatric hospitals' rehabilitation departments using a codesign approach. Children aged 12-18 years with cerebral palsy, parents/caregivers of children (aged 0-18 years) with cerebral palsy, and clinicians will be involved in all stages to codesign the social prescribing programme. The study will consist of three components: (1) 'what we need', (2) 'creating the pathways' and (3) 'finalising and sign off'. This project is overseen by two advisory groups: one group of young adults with cerebral palsy and one group of parents of young people with cerebral palsy. The study will be guided by the biopsychosocial ecological framework, and analysis will follow Braun and Clark's thematic approach.

ETHICS AND DISSEMINATION

The study protocol was approved by the human research ethics committee of the Sydney Children's Hospitals Network. This codesign study will inform a future pilot study of feasibility and acceptability, then if indicated, a pilot clinical trial of efficacy. We will collaborate with all project stakeholders to disseminate findings and undertake further research to build sustainable and scalable models of care.

Epidemiology of cerebral palsy among children in the remote Gorkha district of Nepal: findings from the Nepal cerebral palsy register

PURPOSE

To describe the epidemiology of cerebral palsy (CP) among children in Gorkha, Nepal.

METHODS

We established the first population-based register of children with CP aged <18 y in Gorkha, Nepal (i.e., Nepal CP Register). Children with suspected CP underwent detailed neurodevelopmental assessment by a multidisciplinary assessment team. Socio-demographic, etiology, motor severity, rehabilitation, and educational status were documented.

RESULTS

Between January and October 2018, 182 children with confirmed CP were registered (mean (standard deviation (SD)) age: 10 years 1 months (4 years 10 months), 37.4% females). The majority (88.3%) had CP acquired pre- or perinatally. Mean (SD) age of CP diagnosis was four years five months. Mothers who did not receive any formal schooling had 4.5, 3.1, and 6.3 times higher odds of having inadequate antenatal care, homebirth, and unskilled birth attendants, respectively, when adjusted for other factors. Most children had spastic CP (77.5%) and Gross Motor Function Classification System level III-V (54.9%). Overall, 45.8% had never received rehabilitation services, 58.0% of school-aged children were not attending schools. The median age of receiving rehabilitation services was three years zero months.

CONCLUSIONS

The delayed diagnosis and clinical severity indicate the overall poor health status of children with CP in Nepal which could be improved by ensuring early diagnosis and intervention. Implications for rehabilitationThe first population-based cerebral palsy register in Nepal suggests diagnosis of CP is considerably delayed among children.The high burden of severe motor impairment and poor communication skill with limited access to timely rehabilitation among children with CP in Nepal is concerning.Capacity development of community-based health workers and mothers of children with CP could help implementing community-based programs for prevention and early diagnosis of CP, and to promote early intervention for children with CP in remote Gorkha, Nepal.

Delivering paediatric precision medicine: Genomic and environmental considerations along the causal pathway of childhood neurodevelopmental disorders

Precision medicine refers to treatments that are targeted to an individual's unique characteristics. Precision medicine for neurodevelopmental disorders (such as cerebral palsy, attention-deficit/hyperactivity disorder, obsessive-compulsive disorder, Tourette syndrome, and autism spectrum disorder) in children has predominantly focused on advances in genomic sequencing technologies to increase our ability to identify single gene mutations, diagnose a multitude of rare neurodevelopmental disorders, and gain insights into pathogenesis. Although targeting specific gene variants with high penetrance will help some children with rare disease, this approach will not help most children with neurodevelopmental disorders. A 'pathway' driven approach targeting the cumulative influence of psychosocial, epigenetic, or cellular factors is likely to be more effective. To optimize the therapeutic potential of precision medicine, we present a biopsychosocial integrated framework to examine the 'gene-environment neuroscience interaction'. Such an approach would be supported through harnessing the power of big data, transdiagnostic assessment, impact and implementation evaluation, and a bench-to-bedside scientific discovery agenda with ongoing clinician and patient engagement. WHAT THIS PAPER ADDS: Precision medicine has predominantly focused on genetic risk factors. The impact of environmental risk factors, particularly inflammatory, metabolic, and psychosocial risks, is understudied. A holistic biopsychosocial model of neurodevelopmental disorder causal pathways is presented. The model will provide precision medicine across the full spectrum of neurodevelopmental disorders.

Prevalence and characteristics of children with cerebral palsy according to socioeconomic status of areas of residence in a French department

Aim

To study the association between the socioeconomic environment of area of residence and prevalence and characteristics of children with cerebral palsy (CP).

Method

Data on 8-year-old children with CP born in 2000–2011 (n = 252) were extracted from a regional population-based register in France. The European Deprivation Index (EDI), available at census block level, characterised socioeconomic deprivation in the child’s area of residence at age of registration. The prevalence of CP was estimated in each group of census units defined by EDI distribution tertiles in the general population. The association between deprivation level and CP severity was assessed according to term/preterm status.

Results

CP prevalence differed between deprivation risk groups showing a J-shaped form with the prevalence in the most deprived tertile (T3) being the highest but not significantly different of the prevalence in the least deprived one (T1). However, the prevalence in the medium deprivation tertile (T2) was significantly lower than that in the most deprived one with a prevalence risk ratio (PRR) of: PRRT2/T3 = 0.63 95% CI [0.44–0.89]). Prevalences of CP with associated intellectual disability (ID) and CP with inability to walk were significantly higher in the most deprived tertile compared to the least deprived one (respectively PRRT3/T1 = 1.86 95% CI [1.19–2.92] and PRRT3/T1 = 1.90 95% CI [1.07–3.37]). Compared to children living in the least deprived areas, children with CP born preterm living in the most deprived areas had more severe forms of motor impairment, such as an inability to walk or a combination of an inability to walk and moderate to severe impairment of bimanual function. They also had more associated intellectual disability. No associations were observed among term-born children.

Interpretation

A significant association between area deprivation group and CP severity was observed among preterm children but not among term-born children.

Predictors of range of motion restrictions in children with spastic cerebral palsy: A registry-based study

BACKGROUND

Although children with spastic cerebral palsy (CP) commonly present with restricted passive range of motion (PROM) and contractures, knowledge about the child's characteristics that increase the risk of development of restricted PROM is limited. Identifying children who are more likely to develop contractures is important for early detection and the provision of appropriate medical management. This study aims to identify the most commonly restricted PROM of children with spastic CP and (2) to examine the combined effect of a child's age, gender, gross motor functional classification level and CP subtype on the development of restricted PROM in children with spastic CP.

METHODS

The PROM of 233 children diagnosed with CP was extracted from the national registry of CP in Jordan (CPUP-Jordan) in addition to information about children's age, gender, level of Gross Motor Function Classification System-Expanded and Revised (GMFCS-E&R) and subtype of CP. The mean age of the participants was 3.73 years (SD = 3.14), 57.5% were males and 80.3% had bilateral spastic CP. Point biserial correlations were calculated between the PROM and the child's variables. Multiple binary logistic regressions were conducted to identify the predictors of PROM.

RESULTS

Hip abduction was the most common restricted PROM (57.9%), whereas the hip extension was the least (2.1%). Children with older ages demonstrated more restrictions in knee extension and ankle dorsiflexion; males demonstrated more restriction in hip abduction than females; children with lower GMFCS-E&R levels had more restrictions in hip internal rotation but fewer restrictions in hip abduction and ankle dorsiflexion; and children with bilateral spastic CP had more restrictions in hip abduction than children with unilateral spastic CP.

CONCLUSIONS

PROM of the hip, knee and ankle joints of children with spastic CP was predicted by different sets of child characteristics. Implications for health professionals and follow-up registries of children with CP are provided.

Epidemiology of cerebral palsy in low- and middle-income countries: preliminary findings from an international multi-centre cerebral palsy register

AIM

To describe the epidemiology of cerebral palsy (CP) in children from low- and middle-income countries (LMICs) using data from the Global Low- and Middle-Income Country CP register (GLM-CPR).

METHOD

The GLM-CPR is a multi-country initiative that combines and compares data from children with CP (<18y) in LMICs. Children with CP are registered after detailed neurodevelopmental assessment by a multidisciplinary medical team using a harmonized protocol. Data are collected on agreed core variables. Descriptive analyses are completed to report findings from participating countries.

RESULTS

Between January 2015 and May 2019, 2664 children were recruited from Bangladesh, Nepal, Indonesia, and Ghana (mean age [SD] at assessment: 7y 8mo [4y 8mo], 95% confidence interval 7y 6mo-7y 11mo; male [n=1615] 60.6%, female [n=1049] 39.4%). Overall, 86.6% children acquired CP prenatally and perinatally (e.g. preterm birth, birth asphyxia, neonatal encephalopathy). Median age at CP diagnosis was 3 years. Moreover, 79.2% children had spastic CP and 73.3% were classified in Gross Motor Function Classification System levels III to V. Notably, 47.3% of children never received rehabilitation services (median age at receiving rehabilitation services was 3y; 12.7% received assistive devices) and 75.6% of school-age children had no access to education.

INTERPRETATION

Population-based data show that the proportion of severe cases of CP is very high in LMICs. Children with CP in LMICs lack access to rehabilitation and educational services and a large proportion of children have potentially preventable risk factors, for example, birth asphyxia and neonatal infections. Delayed diagnosis, severe motor impairments, and lack of rehabilitation in most children call for urgent action to identify preventive opportunities and promote early diagnosis and intervention for children with CP in LMICs. What this paper adds The proportion of severe cases of cerebral palsy (CP) is very high in rural low- and middle-income countries (LMICs). Children with CP in LMICs lack access to rehabilitation and educational services. A large proportion of children with CP in LMICs have potentially preventable risk factors.

Dental health status and hygiene in children with cerebral palsy: A matched case-control study

BACKGROUND

Children with cerebral palsy (CP) are at risk for oral pathology and parafunctional habits, and are reliant on caregivers for oral hygiene.

AIM

To evaluate oral hygiene habits and oral examination findings among a group of children with CP and a healthy age- and gender-matched control group.

DESIGN

A comparative, cross-sectional study, consisting of a questionnaire component and a standard dental examination component, each applied to both groups.

RESULTS

Eighty-three children with CP and 84 healthy children were included. Parents of children with CP were more likely to be of low educational level and lack a professional line of occupation (P < .05). Children with CP were less likely to be responsible for oral hygiene maintenance, adhere to toothbrushing, or receive procedural dental care (P < .001). Food packing and drooling were significantly more likely in children with CP. Malocclusion type III was more prevalent among children with CP, as was higher gingival index and gingival enlargement index-horizontal component (P < .001). There were no differences in caries experience between the CP and control groups.

CONCLUSIONS

Children with CP have suboptimal oral hygiene habits, limited access to procedural dental care, higher parafunctional habits, and increased periodontal pathology.

Placental contribution to neonatal encephalopathy

Placental assessment, although currently underused, can inform our understanding of the etiology and timing of Neonatal Encephalopathy (NE). We review our current understanding of the links between placental dysfunction and NE and how this information may inform clinical decisions, now and in the future, emphasizing the four major placental lesions associated with NE. In addition, we discuss maternal and fetal factors that are hypothesized to contribute to specific placental pathologies, especially innate or acquired thrombophilias. We outline the importance of assessing placenta across trimesters and after delivery. As this field continues to evolve, currently available placental histopathological examination methods may need to be combined with advanced prenatal molecular and imaging assessments of placenta and be applied in well-designed studies in large representative populations to better define the links between placental dysfunction and NE.

Exploration of the costs of accessing health services: data from a longitudinal study of young people in transition from paediatric to adult services

BACKGROUND

Economic evaluations that include the patient perspective often base their estimates of patient time and travel costs on data collected at a single point in time. This, however, may be inaccurate if the costs of accessing care change substantially over time, as may be the case for young people in transition from paediatric to adult health services.

AIMS

The aim of this study was to explore the differences in these time and travel costs between two data collection points for young individuals in transition between health care services, and thus to provide an insight of whether such costs should be collected more than once.

METHODS

Descriptive statistics and regression modelling were used to estimate the average difference in costs between the two points of data collection, as well as the potential drivers of those cost differences.

RESULTS

We found a small difference in costs between the two time points, equal to -£45.78 [95% CI: - 89.70 to - 1.86]. The results were largely driven by changes in the unit cost of visits and in the number of attendances.

CONCLUSIONS

A simple and common assumption that patient costs could be collected at a single time point cannot be made in the context of our study. When deciding on the frequency of elicitation of patient costs, future studies should consider the relative impacts of additional data collection on the estimates of efficiency, inequalities and resource implications for collecting new data.

Addressing disparities among children with cerebral palsy: Optimizing enablement, functioning, and participation

PURPOSE

Recognizing health disparities among children with cerebral palsy (CP) is necessary for understanding potential risk factors for CP and for implementing early and effective preventative and intervention treatments. However, there is currently little and conflicting evidence regarding the direct impact of contextual factors such as socioeconomic status (SES) for children with CP in the United States. These contextual factors include the complex social determinants of health on prematurity, comprehensive informed obstetric management for minority and vulnerable populations, and cumulative adversity disproportionately experienced by children, by gender, minority status, immigration, poverty, and structural racism.

METHODS

This study presents results from a review of health disparities among children with CP, using registry and population surveillance data from Australia, Canada, Scandinavia, the United Kingdom, Ireland, Turkey, and the United States.

RESULTS

The review confirmed that there are significant health disparities among children with CP, both in terms of prevalence and severity, based on factors such as SES, neighborhood disadvantage, maternal education, gender, and minority status.

CONCLUSION

Strategies need to be implemented in the United States to promote enablement and functioning among children with CP who face additional health disparities. This requires a greater understanding of population groups at increased risk, comprehensive assessment and care for young children with motor delays, and systematic population counts of children and adults with CP using registries and systems of neurodevelopmental surveillance across health, education, and community rehabilitation. These efforts also require sensitivity to structural and persistent racism, stigma, trauma-informed care, and culturally sensitive community engagement. Additional efforts are also required to improve outcomes over the life course for individuals living a life with CP from a framework of enablement, self-direction, equity and social justice.

Características epidemiológicas da paralisia cerebral em crianças e adolescentes em uma capital do nordeste brasileiro

RESUMO O objetivo deste estudo foi descrever a prevalência de paralisia cerebral entre crianças e adolescentes, seus subtipos, as possíveis comorbidades e as características socioeconômicas das famílias. Foi realizado um estudo epidemiológico do tipo transversal a partir de um inquérito de base populacional sobre a paralisia cerebral em crianças e adolescentes na cidade de Aracaju (SE), Brasil. O estudo obteve informações sobre 240 crianças e adolescentes com paralisia cerebral a partir das respostas a um questionário feitas por seus responsáveis. Foi encontrada a prevalência de período de 1,37 em cada mil. Alguns bairros possuem prevalência de três a quatro vezes maior, revelando que a taxa de prevalência total não é um indicador homogêneo. A maioria dos participantes foi do sexo masculino (56,25%), de raça/cor declarada como parda ou preta (67,50%), sendo que a média de idade foi de 8,56 anos. A paralisia cerebral de tipo espástica bilateral foi a mais frequente (45,42%) e a comorbidade referida na maioria dos casos foi a epilepsia (48,33%). A renda familiar mensal correspondia a $252,87 dólares. O estudo revelou que as crianças e adolescentes com paralisia cerebral são, em grande parte, pertencentes a minorias sociais, de raça/cor parda ou preta, e suas famílias vivem na linha da extrema pobreza.

Emergency Department Use in Children with Cerebral Palsy: A Data Linkage Study

OBJECTIVE

To describe the pattern of emergency department (ED) consultations in children with cerebral palsy (CP) compared to controls and factors predictive of ED consultations.

METHODS

This retrospective cohort study linked data from the Registre de la paralysie cérébrale du Québec (REPACQ) and provincial administrative health databases. The CP cohort was comprised of children enrolled in REPACQ born between 1999 and 2002. REPACQ covers 6 of 17 Quebec health administrative regions. Region-, age-, and gender-matched controls were identified from administrative health databases in a 20:1 ratio. The primary outcome was high use of ED services (≥4 ED visits during the study period). Relative risk (RR) and 95% confidence interval (CI) were calculated.

RESULTS

In total, 301 children with CP were linked to administrative data and 6040 peer controls were selected. Ninety-two percent (92%) of the CP cohort had at least one ED visit in the study period, compared to 74% among controls (RR 1.24, 95% CI 1.19-1.28). Children with CP were more likely than their peers to have high ED use (RR 1.40; 95% CI 1.30-1.52). Factors predictive of high ED use were comorbid epilepsy (RR 1.23; 95% CI 1.04-1.46) and severity of motor impairment (RR 1.14; 95% CI 0.95-1.37).

CONCLUSION

Children with CP are more likely to present to the ED than their peers, resulting in increased use of ED services. Coordinated care with improved access to same-day evaluations could decrease ED use. Health system factors and barriers should be investigated to ensure optimal and appropriate use of ED services.

Hospitalizations in School-Aged Children with Cerebral Palsy and Population-Based Controls

OBJECTIVE

To compare hospitalizations among children with cerebral palsy (CP) and healthy controls and to identify factors associated with hospitalizations in children with CP.

METHODS

This retrospective cohort study linked data from a provincial CP Registry and administrative health databases. The CP cohort was comprised of children born from 1999 to 2002. Age, sex, and region-matched controls were identified from administrative health databases. Mean differences, relative risk (RR), and 95% confidence intervals (CIs) were calculated.

RESULTS

A total of 301 children with CP were linked to administrative health data and matched to 6040 controls. Mean hospitalizations per child during the study period were higher in children with CP compared to controls (raw mean difference (RMD) 5.0 95% CI 4.7 to 5.2) with longer length of stay (RMD 2.8 95% CI 1.8 to 3.8) and number of diagnoses per hospitalization (RMD 1.6 95% CI 1.4 to 1.8). Increased risk of hospitalization was observed in non-ambulant children with CP (RR 1.12 95% CI 1.01 to 1.22) compared to ambulant children and among those with spastic tri/quadriplegic CP compared to other CP subtypes (RR 1.15, 95% CI 1.05 to 1.27). Feeding difficulties (RR 1.20 95% CI 1.13 to 1.27), cortical visual (RR 1.22 95% CI 1.13 to 1.32), cognitive (RR 1.16 95% CI 1.04 to 1.30), and communication impairment (RR 1.26 95% CI 1.10 to 1.44) were associated with increased hospitalizations.

CONCLUSIONS

Children with CP face more frequent, longer hospital stays than peers, especially those with a more severe CP profile. Coordinated interdisciplinary care is needed in school-aged children with CP and medical complexity.

Quality of Life and Health Services Utilization for Spanish Children With Cerebral Palsy

PURPOSE

To examine the health-related quality of life of children with cerebral palsy and its relationship with their use of health resources, taking into account sociodemographic factors concerning the family context.

DESIGN AND METHODS

Cross-sectional study of children with cerebral palsy in Granada (Spain). Quality of life was evaluated with PedsQL questionnaire.

RESULTS

A total of 75 children were analysed (mean age 7.41 years; SD 4.37; 50.7% male). They made an average of 22.80 visits (SD 12.43) per year; greater use was made of resources by children who had been diagnosed with cerebral palsy for <45 months (36.00 vs. 26.93 visits per year, p < 0.0001). Older children suffered more fatigue and pain. Children aged 2-4 years who presented with fatigue had more hospitalizations (r = -0.35; p = 0.20), whereas those >4 years who had a higher quality of life for daily activities had made more visits to hospital A&E (r = 0.35, p = 0.043). Among the children studied, there was no significant association between HRQOL and the parents' education or occupation.

CONCLUSION

These findings highlight variables that may influence children's quality of life and their use of health resources, identifying certain profiles of children who might need individualized interventions.

PRACTICE IMPLICATIONS

These findings could inform services provided by paediatric nurses to children with cerebral palsy, to individualize interventions and improve patient centred care.

Spatial analysis of cerebral palsy in children and adolescents and its association with health vulnerability

Cerebral Palsy (CP) is commonly associated with low socioeconomic status. Use of spatial statistics and a Geographic Information Systems (GIS) are scarce and may contribute to the understanding of CP in a social context. To that end a spatial analysis of CP in children and adolescents was performed to analyze the association of CP with levels of vulnerability in a city (Aracaju, Sergipe) in north-eastern Brazil. In addition, an ecological study was conducted with data obtained from a populationbased survey and secondary data. Exploratory spatial data analysis and linear regression were used. A total of 288 CP cases were identified, with a prevalence of 1.65/1,000 and differences among city neighbourhoods ranging from 0-4/1,000. The mean age of cases studied was 9 years 1 month, with a standard deviation of 5 years 2 months. Most study subjects with cerebral palsy (163) were male (56.4%). The distribution of CP in the study population was not homogeneous throughout the territory. Some areas had clusters, with more cases associated with areas of high vulnerability. Spatial data analysis using GIS was useful to gain an epidemiological understanding of CP distribution that can guide decisionmaking with respect to production, distribution, and regulation of health goods as well as services at the local level.

Transcranial Static Magnetic Field Stimulation of the Motor Cortex in Children

BACKGROUND

Non-invasive neuromodulation is an emerging therapy for children with early brain injury but is difficult to apply to preschoolers when windows of developmental plasticity are optimal. Transcranial static magnetic field stimulation (tSMS) decreases primary motor cortex (M1) excitability in adults but effects on the developing brain are unstudied.

OBJECTIVE/HYPOTHESIS

We aimed to determine the effects of tSMS on cortical excitability and motor learning in healthy children. We hypothesized that tSMS over right M1 would reduce cortical excitability and inhibit contralateral motor learning.

METHODS

This randomized, sham-controlled, double-blinded, three-arm, cross-over trial enrolled 24 healthy children aged 10-18 years. Transcranial Magnetic Stimulation (TMS) assessed cortical excitability via motor-evoked potential (MEP) amplitude and paired pulse measures. Motor learning was assessed via the Purdue Pegboard Test (PPT). A tSMS magnet (677 Newtons) or sham was held over left or right M1 for 30 min while participants trained the non-dominant hand. A linear mixed effect model was used to examine intervention effects.

RESULTS

All 72 tSMS sessions were well tolerated without serious adverse effects. Neither cortical excitability as measured by MEPs nor paired-pulse intracortical neurophysiology was altered by tSMS. Possible behavioral effects included contralateral tSMS inhibiting early motor learning (p < 0.01) and ipsilateral tSMS facilitating later stages of motor learning (p < 0.01) in the trained non-dominant hand.

CONCLUSION

tSMS is feasible in pediatric populations. Unlike adults, tSMS did not produce measurable changes in MEP amplitude. Possible effects of M1 tSMS on motor learning require further study. Our findings support further exploration of tSMS neuromodulation in young children with cerebral palsy.

Impact of social disadvantage on cerebral palsy severity

AIM

To investigate the impact of socio-economic disadvantage on indicators of cerebral palsy (CP) severity - motor impairment, intellectual disability, and the presence of severe comorbidities - in children with CP in Australia.

METHOD

Data from the Australian Cerebral Palsy Register were analysed. Socio-economic disadvantage was assessed using maternal age, maternal country of birth, and a measure of neighbourhood socio-economic status (SES) at the time of the child's birth. Descriptive bivariate analysis, trend analysis, risk ratios, and mediation analysis were undertaken to examine the impact of disadvantage on the indicators of CP severity.

RESULTS

A socio-economic gradient was demonstrated with an increasing proportion of children with non-ambulant status, at least moderate intellectual disability, and the presence of severe comorbidities (having epilepsy, functional blindness, bilateral deafness, and/or no verbal communication) with decreasing neighbourhood SES, adolescent motherhood, and maternal minority ethnicity.

INTERPRETATION

In Australia, socio-economic disadvantage at birth impacts adversely on CP severity at age 5 years. By identifying that socio-economically disadvantaged children with CP are at greater risk of more severe functional outcomes, we can inform targeted interventions at the family and neighbourhood level to reduce these inequities for children with CP.

WHAT THIS PAPER ADDS

Socio-economic disadvantage is associated with increased severity of cerebral palsy functional outcomes. This encompasses low neighbourhood socio-economic status, adolescent motherhood, and maternal minority ethnicity.

Distribution and motor ability of children with cerebral palsy in Scotland: a registry analysis

BACKGROUND AND AIMS

Cerebral palsy is the commonest long-term physical disability in children with a prevalence of between 1.77 and 2.11/1000 live births. In 2013, the Cerebral Palsy Integrated Pathway Scotland (CPIPS) surveillance programme was introduced in all 14 Health Boards in Scotland and provides a standardised musculoskeletal examination of the spine and lower limbs. The purpose of this study was to report the prevalence, subtypes, motor classification and motor ability of children with cerebral palsy in Scotland.

METHODS AND RESULTS

The family/carer's postal address, the child's neurological classification, motor subtypes, Gross Motor Functional Classification (GMFCS) Level and Functional Mobility Scale of 1972 children at first registration in CPIPS 2013-2018 were analysed. Their mean age at first assessment was 7.6 years. There was an overall prevalence of cerebral palsy in Scotland of 2.02/1000. GMFCS levels and Functional Mobility Scale data and prevalence were reported by Health Board and were comparable to that reported elsewhere.

CONCLUSION

For the first time, data are available on the motor abilities of the total population of children with cerebral palsy in Scotland. This information will be highly relevant to resource management of current and future motor needs of these children.

Socioeconomic Status and Pediatric Neurologic Disorders: Current Evidence

Socioeconomic status (SES) is an important risk factor for many neurological disorders and a determinant of health outcomes and quality of life, especially for individuals with neurologic disorders and developmental disabilities. This article focuses on the relationship between SES and pediatric epilepsy, cerebral palsy, autism spectrum disorder, and intellectual disability. Disparities in the prevalence and long-term impact of SES on functioning in persons with disabilities are observed worldwide. Clinicians can use the information presented in the article to target early identification and interventions for improving outcomes in populations most at risk for these disorders and for poor health, social, and economic outcomes.

Promoting the Human Rights of Children With Neurologic Conditions

Children with neurologic conditions benefit from international conventions, and national treaties, policies and regulations that safeguard their human rights. These regulations also exist to serve as guidance in the creation of comprehensive systems of care, inclusive environments, accessible societies and communities that allow these children to thrive and to achieve the best of their capacities. This narrative review of issues related to human rights and advocacy in pediatric neurologic disabilities will provide an overview of the human rights conventions that relate to children with disabilities, and the most current approaches implicating health care providers in rights promotion for these individuals and their families. We also suggest venues for professionals to advocate for their patients, and suggest strategies to consider rights-based approaches as a mean to provide holistic care in a social neurology framework.

The complex aetiology of cerebral palsy

Cerebral palsy (CP) is the most prevalent, severe and costly motor disability of childhood. Consequently, CP is a public health priority for prevention, but its aetiology has proved complex. In this Review, we summarize the evidence for a decline in the birth prevalence of CP in some high-income nations, describe the epidemiological evidence for risk factors, such as preterm delivery and fetal growth restriction, genetics, pregnancy infection and other exposures, and discuss the success achieved so far in prevention through the use of magnesium sulfate in preterm labour and therapeutic hypothermia for birth-asphyxiated infants. We also consider the complexities of disentangling prenatal and perinatal influences, and of establishing subtypes of the disorder, with a view to accelerating the translation of evidence into the development of strategies for the prevention of CP.

Comparison of children diagnosed with cerebral palsy in a private cord blood bank to an epidemiological sample

BACKGROUND

Although cord blood (CB) stem cell research is being conducted for treatment of cerebral palsy (CP), little is known about children with CP and stored CB.

AIMS

To compare demographic and clinical characteristics of children with CP and stored CB to children with CP identified in a population-based study.

METHODS AND PROCEDURES

The Longitudinal Umbilical Stem cell monitoring and Treatment REsearch (LUSTRE®) Registry recruited children from the largest US private CB bank. Demographics, co-morbidities, and gross motor function (GMFCS level and walking ability) were collected and, where possible, compared with the CDC's Autism and Developmental Disabilities Monitoring (ADDM) Network.

OUTCOMES AND RESULTS

114 LUSTRE participants were compared to 451 ADDM participants. LUSTRE participants were more likely to be white, but sex distribution was similar. Co-morbidities (autism and epilepsy) and functional mobility were also similar.

CONCLUSIONS AND IMPLICATIONS

The results of this analysis suggest that while children diagnosed with CP and with access to stored CB differ from a broader population sample in terms of demographics, they have similar clinical severity and comorbidity profiles. As such, LUSTRE may serve as a valuable source of data for the characterization of individuals with CP, including individuals who have or will receive CB infusions.

Association between socioeconomic status and cerebral palsy

Background

The present study investigated the annual prevalence of cerebral palsy (CP) among children aged <7 years in Taiwan and the association between socioeconomic status and CP prevalence.

Methods

Data from the Taiwan National Health Insurance Research Database for the 2002−2008 period were used in this population-based study. Severe and total CP were defined according to catastrophic illness certificate and medical claim records, respectively. The annual CP prevalence was calculated as the number of children with CP among all children aged <7 years.

Results

From 2002 to 2008, the annual prevalence of total and severe CP ranged from 1.9 to 2.8 and from 1.1 to 1.4 per 1000 children, respectively. Boys were 30% more likely to have CP than girls [adjusted relative risk (RR) and 95% confidence interval (CI) ranged from 1.3 (1.2−1.4) to 1.4 (1.2−1.5)]. Low family income was associated with a higher CP prevalence [adjusted RR (95% CI) ranged from 5.1 (4.2−6.2) to 6.4 (5.4−7.6)]. The prevalence of CP in rural area was higher than that in urban or suburban areas. The mortality rate of severe CP ranged from 12.2−22.7 per 1000 children within the 7 years study period.

Conclusions

The prevalence of CP in Taiwan is similar to that in Western countries. A higher prevalence of CP is associated with male sex, low income, and rural residential location. Our findings provide insights into CP epidemiology among the Chinese population.

Effect of rhythmic auditory cueing on gait in cerebral palsy: a systematic review and meta-analysis

Auditory entrainment can influence gait performance in movement disorders. The entrainment can incite neurophysiological and musculoskeletal changes to enhance motor execution. However, a consensus as to its effects based on gait in people with cerebral palsy is still warranted. A systematic review and meta-analysis were carried out to analyze the effects of rhythmic auditory cueing on spatiotemporal and kinematic parameters of gait in people with cerebral palsy. Systematic identification of published literature was performed adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses and American Academy for Cerebral Palsy and Developmental Medicine guidelines, from inception until July 2017, on online databases: Web of Science, PEDro, EBSCO, Medline, Cochrane, Embase and ProQuest. Kinematic and spatiotemporal gait parameters were evaluated in a meta-analysis across studies. Of 547 records, nine studies involving 227 participants (108 children/119 adults) met our inclusion criteria. The qualitative review suggested beneficial effects of rhythmic auditory cueing on gait performance among all included studies. The meta-analysis revealed beneficial effects of rhythmic auditory cueing on gait dynamic index (Hedge's g=0.9), gait velocity (1.1), cadence (0.3), and stride length (0.5). This review for the first time suggests a converging evidence toward application of rhythmic auditory cueing to enhance gait performance and stability in people with cerebral palsy. This article details underlying neurophysiological mechanisms and use of cueing as an efficient home-based intervention. It bridges gaps in the literature, and suggests translational approaches on how rhythmic auditory cueing can be incorporated in rehabilitation approaches to enhance gait performance in people with cerebral palsy.

Accuracy of administrative claims data for cerebral palsy diagnosis: a retrospective cohort study

BACKGROUND

Cerebral palsy is the most common cause of childhood physical disability, with multiple associated comorbidities. Administrative claims data provide population-level prevalence estimates for cerebral palsy surveillance; however, their diagnostic accuracy has never been validated in Quebec. This study aimed to assess the accuracy of administrative claims data for the diagnosis of cerebral palsy.

METHODS

We conducted a retrospective cohort study of children with cerebral palsy born between 1999 and 2002 within 6 health administrative regions of Quebec. Provincial cerebral palsy registry data (reference standard) and administrative physician claims were linked. We explored differences between true-positive and false-negative cases using subgroup sensitivity analysis.

RESULTS

A total of 301 children were identified with confirmed cerebral palsy from the provincial registry, for an estimated prevalence of 1.8 (95% confidence interval [CI] 1.6-2.1) per 1000 children 5 years of age. The sensitivity and specificity of administrative claims data for cerebral palsy were 65.5% (95% CI 59.8%-70.8%) and 99.9% (95% CI 99.9%-99.9%), respectively, yielding a prevalence of 2.0 (95% CI 1.9-2.3) per 1000 children 5 years of age. The positive and negative predictive values were 58.8% (95% CI 53.3%-64.1%) and 99.9% (95% CI 99.9%-99.9%), respectively. The κ value was 0.62 (95% CI 0.57-0.67). Administrative claims data were more sensitive for children from rural regions, born preterm, with spastic quadriparesis and with higher levels of motor impairment.

INTERPRETATION

Administrative claims data do not capture the full spectrum of children with cerebral palsy. This suggests the need for a more sensitive case definition and caution when using such data without validation.

Cerebral palsy

Cerebral palsy is the most common cause of childhood-onset, lifelong physical disability in most countries, affecting about 1 in 500 neonates with an estimated prevalence of 17 million people worldwide. Cerebral palsy is not a disease entity in the traditional sense but a clinical description of children who share features of a non-progressive brain injury or lesion acquired during the antenatal, perinatal or early postnatal period. The clinical manifestations of cerebral palsy vary greatly in the type of movement disorder, the degree of functional ability and limitation and the affected parts of the body. There is currently no cure, but progress is being made in both the prevention and the amelioration of the brain injury. For example, administration of magnesium sulfate during premature labour and cooling of high-risk infants can reduce the rate and severity of cerebral palsy. Although the disorder affects individuals throughout their lifetime, most cerebral palsy research efforts and management strategies currently focus on the needs of children. Clinical management of children with cerebral palsy is directed towards maximizing function and participation in activities and minimizing the effects of the factors that can make the condition worse, such as epilepsy, feeding challenges, hip dislocation and scoliosis. These management strategies include enhancing neurological function during early development; managing medical co-morbidities, weakness and hypertonia; using rehabilitation technologies to enhance motor function; and preventing secondary musculoskeletal problems. Meeting the needs of people with cerebral palsy in resource-poor settings is particularly challenging.
