Functioning and disability after stroke in children: using the ICF-CY to classify health outcome and inform future clinical research priorities

Looking beyond body structure and function: a scoping review of non-impairment impacts of stroke on adolescents

BACKGROUND

Much of the childhood stroke literature has not distinguished impacts for adolescents from those of younger children. Research has also focused on body impairments. With adolescence being a unique period, this scoping review aimed to identify the impacts of childhood stroke on activity, participation, and quality of life for adolescents 13-18 years, and identify how these impacts were determined.

METHOD

This review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). Data pertaining to non-impairment impacts of childhood stroke for adolescents, participant and study characteristics, and measurement instruments were extracted.

RESULTS

Following screening, 79 articles were included, and 33 measurement instruments identified. Only 6 studies reported separate data for adolescents, identifying difficulties with daily activities, social and academic impacts, and reduced quality of life. Impacts of post-stroke communication difficulties on daily activities and schooling were also noted. Measurement instruments developed specifically for adolescents with stroke are lacking.

INTERPRETATION

The review identified limited research reporting non-impairment impacts of childhood stroke for adolescents. Further research specific to this population and the development of measurement instruments for adolescents who have experienced childhood stroke is required to support future research and clinicians working with this population.

An Initial Psychometric Evaluation of a Novel Upper Extremity Pediatric Stroke Hemiplegic Motor Impairment Scale

BACKGROUND

Our team designed an innovative, observation-based motor impairment measure-the Pediatric Stroke Hemiplegic Motor Impairment Scale (Pedi HEMIs). Here we present the results of a survey describing common practices in the pediatric stroke community and the initial psychometric properties of the upper extremity subscale of the Pedi HEMIs (Pedi HEMIs-UE).

METHODS

This is a cross-sectional study whereby participants completed a battery of assessments including the novel Pedi HEMIs-UE. Internal consistency was measured via Cronbach alpha (α). Intraclass correlation (ICC) was used to assess inter-rater reliability (IRR). Concurrent validity was investigated using Pearson or polychoric correlations and simple linear regressions.

RESULTS

The study sample consisted of 18 children aged 1.08 to 15 years. Two participants completed two sets of evaluations, totaling 20 data sets. Cronbach α, a measure of internal consistency, was on average 0.91 (range: 0.89 to 0.92). IRR was excellent with the six raters in almost perfect agreement (ICC = 0.91; 95% confidence interval [CI]: 0.83 to 0.96). Pearson correlation coefficient between the Pedi HEMIs-UE and logit Assisting Hand Assessment (AHA)/mini-AHA was -0.938 (95% CI: -0.979 to -0.827, P < 0.001), indicating excellent concurrent validity.

CONCLUSIONS

We found excellent feasibility, reliability, and validity of the Pedi HEMIs-UE in a convenience sample of youth with hemiparesis after stroke.

Child and family health-related quality of life and participation outcomes and goals after acquired brain injury: a cross-sectional survey

OBJECTIVE

To explore longer-term health-related quality of life (HRQoL) and participation outcomes and goals of children and young people (CYP) with acquired brain injuries (ABI) and their families in a region of the UK and the impact of the COVID-19 pandemic.

METHODS

Cross-sectional survey of (5-18 CYP) and their parent-carers 12-43 months following ABI. Included measures of HRQoL, participation, family function and parental wellbeing and demographic and free text questions.

RESULTS

Ninety-five responses (30% response) were received. 67% of CYP were at risk of impaired HRQoL, 72% had severely impaired participation. 53% of parent-carers reported reduced HRQoL and family functioning, 37% of parent-carers screened positive for anxiety/depression. Relationships exist between CYP participation and HRQoL and parental HRQoL and family functioning. Goals were overwhelmingly activity and participation focused. Participants described the global impact of an ABI on the CYP and family as well as the additional impact of the COVID-19 pandemic on CYP and family wellbeing.

CONCLUSION

ABI significantly impacts CYP participation and both CYP and parent-carer wellbeing in the long-term, potentially further impacted by the COVID-19 pandemic. Rehabilitation interventions should address both participation and the psychological wellbeing of CYP with ABI and their parent-carers.

Functional outcomes of pediatric hemispherotomy: Impairment, activity, and medical service utilization

OBJECTIVE

The purpose of this study was to describe the functional outcomes of hemispherotomy in a pediatric cohort, including impairments, activity limitations, utilization of therapies and medical specialist services, and subsequent surgical intervention.

METHODS

We conducted a retrospective review of patients who underwent hemispherotomy at UPMC Children's Hospital of Pittsburgh from 2001 to 2021. Data on impairments, activity limitations in mobility, self-care, and communication, and use of re/habilitative therapies and medical specialist services were collected pre-operatively and at 1, 5, 10, and 15 years postoperatively. Seizure outcomes were reported via Engel classification at the longest follow-up interval and subsequent surgical procedures were documented through the latest follow-up interval.

RESULTS

A total of 28 patients who underwent hemispherotomy were assessed prior to surgery, 26 at 1 year post-op, 13 at 5 years, 9 at 10 years, and 5 at 15 years. Seizure outcomes at the longest follow-up interval showed that 84.6% of patients were seizure-free. Assessment of impairments to body structure & function from baseline to 1-year post-op revealed increased impairment in 73% of patients, while most patients saw no change in impairment at 5 years (69%), 10 years (100%), and 15 years (100%) post-op compared to the previous time point. Muscle tone abnormalities (100%), hemiparesis (92%), and visual field deficits (85%) were the most frequently observed impairments in the first year following surgery. Most patients saw no change in developmental or cognitive-affective impairments at 1 (65%), 5 (85%), 10 (89%), and 15 years (80%) post-op compared to the previous time point. The only qualitative reports of decreased ability occurred in 2/26 patients whose medical records indicated decreased mobility at the 1-year mark. All further qualitative reports of ability in mobility, self-care, and communication domains indicated increases or no change in ability for all patients at each of the subsequent follow-up intervals. Exploration of the utilization of re/habilitative therapy services shows that 84% of patients received at least one therapy service at baseline, 100% at1 year, 92% at 5 years, 100% at 10 years, and 80% at 15 years post-op. Patients were followed, on average (m), by multiple medical specialist services at baseline (m = 2.58) as well as the 1- (m = 1.70), 5- (m = 2.15), 10- (m = 3.00) and 15-year (m = 3.40) follow-up intervals. Following hemispherotomy, 15 (53.6%) patients required an average of 2.21 additional surgeries. Most often required was orthopedic surgical intervention (n = 16 procedures), followed by shunt placement (n = 7) and revision (n = 14) targeting hydrocephalus.

SIGNIFICANCE

This retrospective study demonstrates expected increases in impairments such as hemiparesis and visual field deficits (i.e., homonymous hemianopia) in the context of increased activity and favorable seizure outcomes for 28 pediatric patients who underwent hemispherotomy for drug-resistant epilepsy. Most patients required rehabilitative therapies prior to surgery and continued to require these services post-operatively. Reported baseline functional status, the persistence of impairments following surgery, and comorbidities among this cohort underscore the medical complexity of this patient population and the importance of multidisciplinary care both pre-and post-operatively.

Neurological and Functional Outcomes after Pediatric Stroke

Pediatric stroke results in life-long morbidity for many patients, but the outcomes can vary depending on factors such as age of injury, or mechanism, size, and location of stroke. In this review, we summarize the current understanding of outcomes in different neurological domains (eg, motor, cognitive, language) for children with stroke of different mechanisms (ie, arterial ischemic stroke, cerebral sinus venous thrombosis, and hemorrhagic stroke), but with a focus on World Health Organization International Classification for Functioning, Disability, and Health (ICF-CY) framework for measuring health and disability for children and youth. We describe outcomes for the population as a whole and certain factors that may further refine prognostication.

Functional outcomes in children related to self-care, mobility, and social function after stroke in early childhood: a cohort study

ABSTRACT Background: Stroke has been increasingly recognized as an important morbidity and mortality factor in neonates and children. Children have different and more diverse risk factors than adults, commonly related to an underlying disease. Stroke may compromise functional capacity in children. Few studies have focused on functional outcomes related to activities and participation. Objectives: To investigate post-stroke functionality of children related to self-care, mobility, and social function. Methods: We assessed the functional outcome of 14 children younger than 7.5 years who suffered a stroke in early childhood through the use of the Pediatric Evaluation of Disability Inventory (PEDI). Results: The average age of the sample at assessment was 3.6 ± 1.4 years (2 - 6 years). The average scores in the PEDI functional domains of self-care, mobility, and social function were, respectively, 37.6 ± 15.4, 36.2 ± 15.4, and 48.7 ± 11.1. Children showed age-appropriate functional outcomes in the PEDI functional domains: 71.4% of them in self-care and mobility and 92.9% in social function. Children with bilateral injuries (p = 0.05) and longer hospital stays (r = -0.79, p = 0.001) showed the worst scores in PEDI's social function domains. Conclusions: Overall, our sample of preschool children showed age-appropriate functional outcomes on self-care, mobility, and social function domains after stroke. However, children with bilateral injuries and longer hospital stays showed the worst scores in social function domains. We recommend focusing on functional rehabilitation to promote activities and participation and to monitor the development of children's social skills after stroke.

Participation after childhood stroke: Is there a relationship with lesion size, motor function and manual ability?

BACKGROUND

Childhood arterial ischemic stroke (AIS) is associated with significant morbidity with up to 50% of affected children developing hemiparesis. Hemiparesis is assumed to influence participation within the peer group, but it is unclear to what extent its severity affects participation in different areas of social life.

METHODS

Thirteen children (mean age 9y6m) with AIS (6 without hemiparesis, 7 with hemiparesis) and 21 controls (mean age 9y8m) participated. We scored hemiparesis severity with hand strength asymmetry (pinch and grip strength), measured with a dynamometer. We assessed manual ability (ABILHAND-Kids), socioeconomic status (Family Affluence Scale) and participation (Participation and Environment Measure - Children and Youth). From structural MRI, we measured lesion size. We investigated differences in participation and its relationship with hemiparesis severity using non-parametric partial correlations (controlling for lesion size, manual ability, and socioeconomic status), interpreted as absent (r < 0.25), weak (r = 0.25-0.50), moderate (r = 0.50-0.75) or strong (r > 0.75). Analyses were performed in jamovi 1.6.3.

RESULTS

Children with AIS (with or without hemiparesis) showed reduced participation frequency at school (p < 0.001), whilst participation at home and in the community resembled that of their peers. Severity of hemiparesis was moderately related to frequency and involvement at home and to involvement and desire for change in the community, although unrelated to school participation.

CONCLUSION

Reduced participation in school life requires close attention in the follow-up of children with AIS - regardless of the severity of hemiparesis. Participation at home and in the community is related to hemiparesis severity and may be improved with participation-focused motor intervention strategies.

Outcomes for children with acquired brain injury (ABI) admitted to acute neurorehabilitation

AIM

To evaluate an innovative paediatric neurorehabilitation model in relation to improving quality of neurorehabilitation and reducing length of stay (LOS) for children with acquired brain injury.

METHOD

A process evaluation approach was conducted in line with Medical Research Council evaluation of complex interventions guidance. Analysis was conducted on routinely collected patient data from 2017 to 2018, including LOS and family feedback. Descriptive and inferential statistics were used for quantitative analysis and qualitative data was analysed thematically.

RESULTS

Outcomes for 70 children (0-16y, median age 5y, IQR 1-11y, 46 males, 24 females) referred to the service indicated improved function and reduced complexity of need. The mean LOS was 10.6 days compared to baseline mean LOS of 41 days (2011-2012). High satisfaction from the families was recorded; however, ongoing needs and service gaps regarding long-term support were identified.

INTERPRETATION

This service model is effective in delivering quality paediatric neurorehabilitation, demonstrating a sustained impact on LOS, and positive patient outcome data and family feedback for this group of patients. What this paper adds Investment in early intensive neurorehabilitation and supported discharge impacts length of stay (LOS) for children with acquired brain injury. Early intensive neurorehabilitation and supported discharge is effective. This is demonstrated by a sustained reduction in LOS, positive patient outcomes, and family feedback.

Exploring participation after paediatric acquired brain injury

This study aimed to explore the levels of participation in a UK sample of children and young people (CYP) with an acquired brain injury (ABI) at home, school and in the community through a cross-sectional study. The Child and Family Follow-Up Survey was distributed to parents/carers of 134 CYP with ABI (CYP-ABI) who received neuro-rehabilitation from 2014 to 2016. Access and recruitment were problematic resulting in a low response rate (4%). Widespread restrictions in participation were reported by four of the five respondents with community-structured events/activities and educational activities being the most restricted. Factors impacting on participation were cognitive-based and movement skills, family stress and lack of support/encouragement in the community. Study results provide information pertaining to the feasibility of undertaking research with this population while also highlighting the restrictions to participation experienced by CYP-ABI more than two years after injury.

Validation of the pediatric stroke outcome measure for classifying overall neurological deficit

BACKGROUND

The pediatric stroke outcome measure (PSOM) is a standardized, disease-specific outcome measure. We aimed to validate the overall classification of neurological deficit severity using PSOM.

METHODS

We identified 367 neonates/children with arterial ischemic stroke (AIS) (Derivation Cohort). We analyzed the PSOM subscales (scored as 0 [no deficit], 0.5 [minimal/mild deficit; normal function], 1 [moderate deficit; slowing function], or 2 [severe deficit; missing function]) to derive severity levels using latent class analysis (LCA). We validated a severity classification scheme (PSOM-SCS) in: (a) children who had Pediatric Evaluation of Disability Inventory (PEDI; n = 63) and/or the Pediatric Quality-of-Life Inventory (PedsQL; n = 97) scored; and (b) an external cohort (AIS; n = 102) with concurrently scored modified Rankin Scale (mRS), King's Outcome Scale for Childhood Head-Injury (KOSCHI) and PSOM.

RESULTS

Within the Derivation Cohort, LCA identified three severity levels: "normal/mild," "moderate," and "severe" (83.7%, 13.3%, and 3%, respectively). We developed severity classification based on PSOM subscale scores: "normal/mild"-normal function in all domains or slowing in one domain, "moderate"-slowing in ≥2 domains or missing function in one domain, and "severe"-missing function in ≥2 domains or slowing in ≥1 plus missing in one domain. PEDI and PedsQL both differed significantly across the severity groups. PSOM-SCS displayed high concordance with mRS (agreement coefficient [AC2] = 0.88) and KOSCHI (AC2 = 0.79).

CONCLUSION

The PSOM-SCS constitutes a valid tool for classifying overall neurological severity emphasizing function and encompassing the full range of severity in pediatric stroke.

IMPACT

Arithmetic summing of the PSOM subscales scores to assess severity classification is inadequate.The prior severity classification using PSOM overestimates poor outcomes.Three distinct severity profiles using PSOM subscales are identified.The PSOM-SCS is in moderate to excellent agreement with other disability measures.PSOM-SCS offers a valid tool for classifying the overall neurological deficit severity.

Following severe childhood stroke, specialised residential rehabilitation improves self-care independence but there are ongoing needs at discharge

Introduction

Stroke is a major cause of mortality and disability in childhood. There is a false belief that children will recover better than adults and recent research confirms that younger age at injury can have a negative impact on rehabilitation outcomes, resulting in lifelong disability. Self-care is a key rehabilitation outcome for children and young people.

Methods

This service evaluation reviews routinely collected clinical self-care data from one specialised residential rehabilitation centre in the United Kingdom. Admission and discharge scores from the United Kingdom Functional Independence Measure +Functional Assessment Measure, Rehabilitation Complexity Scale – E and Northwick Park Nursing Dependency Scale were analysed.

Results

Twenty-six children and young people age 8 years and over with severe stroke were included. Mean scores of independence increased and mean scores of complexity and dependency decreased. A proportion of the sample had ongoing self-care needs in relation to support needed in washing, dressing and bathing. A small number remained highly dependent, requiring assistance from two carers.

Conclusion

Children and young people make significant gains in self-care independence during specialised rehabilitation. However, a proportion return to the community with high self-care needs. Occupational therapists and the wider care team should address ongoing self-care needs in this population.

Australian clinical consensus guideline for the subacute rehabilitation of childhood stroke

Childhood stroke results in long-term, multifaceted difficulties, affecting motor, cognitive, communication, and behavioral domains of function which impact on participation and quality of life. The Childhood Stroke Consensus Rehabilitation Guideline was developed to improve the care of children with stroke by providing health professionals with recommendations to assist in their rehabilitative treatment. Clinical questions were formulated to inform systematic database searches from 2001 to 2016, limited to English and pediatric studies. SIGN methodology and the National Health and Medical Research Council system were used to screen and classify the evidence. The Grade of Recommendation, Assessment, Development and Evaluation system was used to grade evidence as strong or weak. Where evidence was inadequate or absent, a modified Delphi consensus process was used to develop consensus-based recommendations. The guideline provides 56 recommendations (1 evidence-based recommendation and 55 consensus recommendations). These relate to the framework of rehabilitation service delivery as well as domain-specific rehabilitation treatment strategies for each domain of function. It is anticipated that this guideline will provide health professions with recommendations to improve the subacute care of children with stroke both in Australia and internationally.

A child in shock: carotid blowout syndrome

Paediatricians commonly encounter neck lumps during their routine clinical practice; vascular abnormalities, such as (pseudo)aneurysms, are a rare cause of these. Pseudoaneurysms of the carotid artery in children are usually the result of blunt or penetrating trauma, infection or vasculitis/connective tissue disorders. They can present with a variety of symptoms including neck pain, as a pulsatile neck mass or with compressive symptoms (for example, cranial nerve palsies or dyspnoea). Pseudoaneurysms carry a risk of rupture in which case they are fatal, unless immediate treatment is provided.We report a 17-month-old male child with idiopathic carotid artery blowout syndrome presenting with acute oropharyngeal haemorrhage leading to asystolic cardiac arrest. He was successfully resuscitated and emergency embolisation controlled the bleeding. Despite extensive left hemispheric infarct, he has survived.Carotid artery blowout syndrome needs to be recognised as a potential cause of major haemorrhage in childhood. The purpose of this case report is to remind readers of the differential diagnosis and work-up of a child presenting with a neck lump, to highlight important aspects of the acute management of major haemorrhage and massive blood transfusion in paediatrics, to describe the aetiology, presentation and management of carotid artery pseudoaneurysm in children and to discuss long term rehabilitation in patients with consequent neurological sequelae (including the need for input from multiple specialty teams).

Mapping the primary outcomes reported in Cochrane systematic reviews regarding stroke with the International Classification of Functioning, Disability and Health domains: current trend and future recommendations

BACKGROUND

The International Classification of Functioning, Disability and Health (ICF) serves as a framework for defining and categorizing health and functioning. ICF could be used to classify research outcomes in a systematic manner.

AIM

The aim of this study was to classify the primary outcomes used in Cochrane Systematic Reviews (CSRs) into the ICF domains of functioning; to describe the differences in primary outcomes in reviews related to rehabilitation intervention and non-rehabilitation intervention; and to describe the trend of outcome selections according year of publication.

DESIGN

Methodological paper.

POPULATION

Adult stroke population.

METHODS

We analyzed the primary outcomes used in the CSRs published by the Cochrane Stroke Review Group up to December 2017. The primary outcomes were extracted and classified into the ICF domains of functioning (body functions, body structures and activity and participation).

RESULTS

One hundred and seventy-four papers with 216 primary outcomes were included in this analysis. Less than half (102/216, 47.2%) of the outcomes could be classified into the ICF domains of functioning. For the outcomes that could be classified into the ICF domains, the majority (72/102, 70.5%) were in the activity and participation domain, followed by body functions (26/102, 25.5%) and body structures (4/102, 4.0%). Of the outcomes that could not be classified into the ICF domains (N.=114), death (81/114, 71.1%) and recurrent stroke (21/114,18.4%) formed the majority of the outcome. There were 75 CSRs on rehabilitation related interventions; the majority of the outcomes (75/97, 77.3%) used in rehabilitation related CSRs could be classified into the ICF framework with more than half (49/75, 65.3%) in the activity and participation domain.

CONCLUSIONS

The majority of the primary outcomes selected by the Cochrane Stroke Review Group in their CSRs could not be classified into the ICF domains of functioning. Death and recurrence of vascular events remains the major outcome of interest. In rehabilitation related interventions, activity and participation domain is the functioning domain most commonly used.

CLINICAL REHABILITATION IMPACT

The systematic use of patients-centered ICF-based outcomes in CSRs could help the application of evidence in clinical decision making.

Self-reported needs after pediatric stroke

BACKGROUND

Pediatric stroke has the potential for long term impact on the lives of children and their families. Child-centred intervention depends on understanding of needs from diagnosis onwards. However, little is known about the health and care support self-reported needs of this population.

AIMS

This study aimed to describe the nature and extent of needs (met and unmet) of pediatric stroke patients and their families and compare these with previously reported adult stroke needs.

METHODS

The questionnaire, adapted from a previously published adult stroke study, was conducted with parents of children who had an ischemic or haemorrhagic stroke between birth - 18 years, and young people with stroke now aged between 12 and 18 years. Participants were recruited from three tertiary pediatric stroke clinics in England. Levels and type of needs, and self-reported neurological impairment were captured. Comparisons of needs was reported descriptively and explored using Chi-square test.

RESULTS

Of 44 participants (39 parents, 5 young people), over two thirds reported at least one unmet need. Over half had difficulties in school-related activities, and over one-third in leisure activities and social relationships. Participants reported similar nature and extent of need when compared to previously reported adult stroke needs. Higher severity of neurological impairment was associated with higher number of needs.

CONCLUSIONS

Children and young people and their parents have high levels of unmet need across a range of health domains in the months and years after pediatric stroke. This information supports the importance of a needs-based approach to maximising health and well-being.

O impacto do acidente vascular cerebral na qualidade de vida de crianças e adolescentes

RESUMO O objetivo deste estudo foi avaliar a qualidade de vida (QV) de crianças/adolescentes com diagnóstico de acidente vascular cerebral (AVC) segundo as percepções do responsável e das próprias crianças/adolescentes comparados com um grupo controle (GC). Participaram 78 sujeitos divididos em: Grupo de crianças/adolescentes que tiveram histórico de AVC (GAVC, n=39) e um Grupo de crianças/adolescentes saudáveis como Controle (GC, n=39), sendo pareados por sexo e idade. Utilizou-se de entrevista semiestruturada para descrever os aspectos sociodemográficos e do instrumento Pediatric Quality of Life Inventory (PedsQLTM 4.0) para avaliar a QV dos sujeitos no seu desenvolvimento. A mediana de idade do diagnóstico de AVC do GAVC foi sete meses, sendo que a maioria apresentou AVC isquêmico (71,8%) e hemiparesia. De acordo com os responsáveis do GAVC, a Capacidade Funcional dos seus filhos foi significativamente diferente, apresentando inferioridade em relação ao GC. Para os responsáveis também a variável escolaridade do pai manteve efeito positivo significativo nos aspectos emocionais da criança, e a variável idade da criança/adolescente e tempo do AVC >29 dias de vida apresentou efeito negativo nos aspectos escolares. Já para as crianças/adolescentes, a variável idade em que entrou na escola e gênero apresentou efeito significativo negativo no desfecho de aspectos escolares em relação ao GC. Concluímos que a percepção dos responsáveis difere da percepção da criança/adolescente em relação à capacidade funcional desta; a escolaridade do pai influenciou positivamente nos aspectos emocionais da criança, e as crianças sentem-se com um prejuízo no desempenho escolar, principalmente os meninos.

Characterization of communication disorders according to the categories of the International Classification of Functioning, Disability and Health - Children and Youth (ICF-CY)

PURPOSE

Characterize the performance of outpatients regarding aspects of communication disorders according to the categories of the International Classification of Functioning, Disability and Health - Children and Youth Version (ICF-CY).

METHODS

This is a descriptive, observational study based on a retrospective analysis of secondary data collected at a Speech-language Pathology outpatient clinic of the public health network, from records of patients aged 5-16 years, evaluated between 2010 and 2014. Elements of anamnesis and assessment reports were analyzed with identification of ICF-CY categories related to the following components: Body Functions, Activities and Participation, and Environmental Factors. These categories were defined as the study variables, stored as categorical variables, and had their frequency distribution investigated by descriptive statistical analysis.

RESULTS

One hundred eighty medical records were included in the study, and 65 of the 168 pre-selected categories were identified. As for the component Body Functions, 13 items were verified, with the category related to impairment in Mental functions of language as the most frequently mentioned. Of the 34 categories identified in the component Activities and Participation, Learning to read - Performance and Doing housework - Performance were the ones that most frequently presented difficulties. Of the 18 categories of the component Environmental Factors, the one described in most reports as Barrier was Individual attitudes of acquaintances, peers, colleagues, neighbors, and community members.

CONCLUSION

Changes were found in categories of the three components of the ICF-CY analyzed, indicating the existence of issues that affected the functional performance regarding aspects of communication disorders of children and adolescents assisted at an outpatient environment.

Improving cognitive outcomes for pediatric stroke

PURPOSE OF REVIEW

The past 20 years have seen a 35% increase in prevalence of pediatric stroke. Contrary to widely held views, children do not recover better than adults. This review explores the impact of pediatric stroke on cognitive domains, including intellectual and executive functions, memory and behavior, and the influence of age, lesion characteristics, and comorbidities on outcome.

RECENT FINDINGS

Cognitive problems occur in up to half of ischemic and hemorrhagic stroke survivors. Single-center studies have shown intelligence quotient scores skewed to the lower end of the average range, with greater impairment in performance than verbal domains. Executive function, such as attention and processing speed are particularly vulnerable to the effects of pediatric stroke. Age at stroke, larger infarct size, cortical/subcortical lesion location, epilepsy, and comorbid physical deficits are associated with poorer cognitive outcomes.

SUMMARY

Cognitive impairment occurs relatively frequently following pediatric stroke but the nature, severity, and predictors of specific deficits are not well defined. Improving understanding of outcomes following pediatric stroke is a key priority for families but a paucity of data limits the ability to develop targeted disease, and age-specific pediatric rehabilitation strategies to optimize cognitive outcomes following pediatric stroke.

Measuring changes in functional ability in older children and young people with acquired brain injury using the UK FIM + FAM

Introduction

There is a need for validated and responsive measurement tools to demonstrate changes in functional ability. Existing outcome measurement tools have significant limitations for children and young people with acquired brain injury (ABI).

Aim

This study examines the potential of the UK Functional Independence Measure + Functional Assessment Measure (UK FIM + FAM) to detect clinical change in older children and young people with ABI.

Method

This is a secondary retrospective pretest–post test analysis of 72 children and young people age 8–17 years. Internal responsiveness was examined using Wilcoxon signed-rank tests and effect sizes indices; external responsiveness was examined in relation to the Neurological Impairment Scale (NIS) using Spearman’s correlation coefficient.

Results

Highly significant changes were detected from admission to discharge on motor, cognitive and total UK FIM + FAM scores ( p < 0.001). Medium to large effect sizes were found on the total scale indicating good internal responsiveness. There was a significant, negative correlation between UK FIM + FAM change scores and NIS change scores ( p < 0.01) indicating good external responsiveness.

Conclusion

The UK FIM + FAM was able to detect clinically meaningful change in functional ability in children and young people with ABI over 8 years. Further validity and reliability must be established before recommending its use in this client group.

Psychosocial outcome and quality of life following childhood stroke - A systematic review

OBJECTIVES

The aim of this paper was to critically review the recent literature on psychosocial and behavioral outcome following childhood stroke, to assess whether quality of life is affected and to investigate the factors related to psychosocial outcome.

METHODS

Literature searches were conducted and identified 36 relevant papers from the period 1908-2016.

RESULTS

The systematic review found that many children experience difficulties in a wide range of psychosocial domains. Quality of life can also be significantly reduced. Inconsistent findings regarding the correlates of outcome are likely due to methodological limitations. These issues include small and heterogeneous samples, lack of control groups, and measurement difficulties.

CONCLUSIONS

This systematic review strongly indicates that childhood stroke can affect a myriad of psychosocial domains and a child's quality of life. Methodological issues, particularly around heterogeneous samples and measures, limit the conclusions that can be drawn regarding the predictors of outcome.

Prevalence and Predictors of Long-Term Functional Impairment, Epilepsy, Mortality, and Stroke Recurrence after Childhood Stroke: A Prospective Study of a Chilean Cohort

BACKGROUND

To evaluate the prevalence and predictors of long-term impairment, epilepsy, mortality, and recurrences after the first stroke in a cohort of Chilean children.

METHODS

A prospective study involving 98 children who suffered a first stroke and underwent follow-up for at least 3 years in a single center. Functional outcome was measured using the modified Rankin Scale for children. We utilized multivariate logistic regression models to estimate the odds ratios (ORs) for outcomes while adjusting for age, sex, and underlying conditions (significance <.05).

RESULTS

Stroke recurrences were present in 18 children and were strongly associated with arteriopathies (OR 8.11; CI 1.5-43). Of 26 children who died during the follow-up period, a significant proportion had a cardiopathy (OR 6.57; CI 1.3-32) or a chronic head and neck disease (OR 41.3; CI 3.5-490). Among 72 survivors (median age 1.49 years; 38 girls; mean follow-up time 4.85 years), 28 presented marked impairment; these children were younger (P = .019) and had more commonly arteriopathies (OR 9.33; CI 1.7-51) and epilepsy (OR 10.5; CI 3.1-36) as compared to survivors without disabilities. Cumulative epilepsy prevalence was 55.6%; children with epilepsy were younger (P = .037) and had more commonly acute symptomatic seizures (OR 12.16; CI 2.93-50.4) as compared to survivors without epilepsy.

CONCLUSIONS

The prevalence of long-term adverse outcomes after childhood stroke is high and does not differ from other geographical and racial groups. Younger age, acute seizures, and arteriopathies but not sex and other underlying conditions predict adverse outcome following childhood stroke.

Factors Associated with Six-Month Outcome of Pediatric Stroke

Background

Pediatric stroke outcome studies are often cross sectional in design. Prospective information regarding the clinical course following diagnosis is lacking, but may inform clinical management beyond the acute period.

Aims

To describe the outcome of arterial ischemic stroke in infants, children and adolescents at one-month and six-months post-stroke across health domains, and explore the relationship between lesion characteristics and early outcome with six-month adaptive behavior.

Methods

A single center prospective longitudinal study at a tertiary level children's hospital. Recruitment was undertaken from December 2007 to January 2012. Participants were children aged birth to 18 years presenting acutely with first diagnosed arterial ischemic stroke. Lesion characteristics on brain imaging were classified. Children were grouped according to age at diagnosis for analysis (neonates vs. those aged >30 days).

Results

In 50 children with a median age of 47 months at diagnosis, sensorimotor impairments were most evident upon neurological examination acutely, especially in the older children. At both one-month and six-months motor functioning was significantly impaired in the older age group but no significant cognitive or language sequelae were identified. Lesion characteristics alone were not associated with six-month adaptive behavior outcomes.

Conclusions

For patients surviving arterial ischemic stroke, the most significant clinical consequences both acutely and at six-months, are sensorimotor impairments, particularly evident in the older children. In contrast cognitive or language sequelae were not identified. Long-term surveillance is required to describe clinical course and rehabilitation needs, particularly for neonates and infants.

Preliminary reliability and validity of a battery for assessing functional skills in children with Sturge-Weber syndrome

PURPOSE

The purpose of this study was to evaluate inter-rater reliability and validity of a proposed functional outcome battery for clinical trials in children with Sturge-Weber syndrome (SWS).

METHODS

Ten children were evaluated twice on the same day using a series of functional outcome measures selected for sensitivity to the range of age and function of children with SWS: Modified Rankin Scale, Pediatric Evaluation of Disability Index, Modified House Functional Classification, and a modified version of the Erhardt Developmental Prehension Assessment. Inter-rater reliability was calculated, and criterion validity was explored through correlations with the Sturge-Weber Syndrome-Neurological Rating Score (SWS-NRS).

RESULTS

Inter-rater reliability was high across all measures. Correlations were identified between the SWS-NRS and the study measures.

CONCLUSIONS

The proposed battery of functional outcome measures captures child's functioning at the levels of impairment, activity and participation and is robust to evaluation by different raters and across sessions on the same day. This battery is expected to be sensitive to treatment-related changes in qualitative patterns of hand use, functional skills, and/or change in independence in daily living.
