Common medical comorbidities associated with cerebral palsy

Orthopedic surgery and mobility goals for children with cerebral palsy GMFCS level IV: what are we setting out to achieve?

BACKGROUND

Multilevel orthopedic surgery is considered to be the gold standard treatment for ambulatory children with cerebral palsy (CP), classified at levels I, II, or III according to the Gross Motor Function Classification System (GMFCS). Hip enlocation and stability are the main goals of orthopedic intervention in the GMFCS level IV subgroup and are well researched; however, there is no evidence to date to support or challenge the effectiveness of orthopedic treatment to preserve functional mobility in this patient group. The aim of this study was to evaluate the results of orthopedic surgery to maintain or restore standing transfers and supported walking in children with CP at GMFCS level IV.

METHODS

Twenty-two children with CP GMFCS level IV who underwent orthopedic surgery to improve mobility between the years 2004 and 2008 were included in this study. A retrospective chart review was performed and a satisfaction questionnaire sent to all patients. The primary outcome measure was the attainment and maintenance of mobility goals 2 years post-surgery. The secondary outcome measures were family/patient satisfaction, Functional Mobility Scale (FMS), and complications.

RESULTS

The two goals identified by the patients and carers were standing transfers and supported walking. At the 2-year post-surgery assessment, 14 children (63.6 %) did not reach their pre-determined goals. In the questionnaire, 21.4 % of the families reported that surgery was not beneficial. The FMS score remained unchanged in 95.4 % of the patients. Fourteen patients (63.6 %) had at least one complication that prolonged their post-operative rehabilitation (e.g., neuropraxia).

CONCLUSION

This study suggests that orthopedic surgery in children with CP at GMFCS level IV is unlikely to maintain or restore mobility. Furthermore, it carries a significant risk of complications.

LEVEL OF EVIDENCE

Case series, Level IV.

Medical expenditures attributable to cerebral palsy and intellectual disability among Medicaid-enrolled children

This study estimated medical expenditures attributable to cerebral palsy (CP) among children enrolled in Medicaid, stratified by the presence of co-occurring intellectual disability (ID), relative to children without CP or ID. The MarketScan(®) Medicaid Multi-State database was used to identify children with CP for 2003-2005 by using the International Classification of Diseases, Ninth Revision; Clinical Modification (ICD-9-CM) code 343.xx. Children with ID were identified for 2005 by using ICD-9-CM code 317.xx-319.xx. Children without CP or ID during the same period served as control subjects. Medical expenditures were estimated for case and control children for 2005. The difference between the average expenditures for children with and without CP was used as a proxy for attributable expenditures for the condition. The attributable expenditures of co-occurring ID were calculated similarly as the difference in average expenditures among children with CP with and without ID. A total of 9927 children with CP were identified. Among them, 2022 (20.3%) children had co-occurring ID recorded in medical claims. Children with CP but without ID incurred medical expenditures that were $15,047 higher than those of control children without CP or ID. By contrast, children with CP and co-occurring ID incurred costs that were $41,664 higher, compared with control children, and $26,617 more than children with CP but without ID. Administrative data from a large, multistate database demonstrated high medical expenditures for publicly insured children with CP. Expenditures approximately tripled for children with CP and co-occurring ID.

Sleep problems in physically disabled children and burden on caregivers

AIM

The present study was implemented to investigate relationships between sleep problems in physically disabled children and sleep quality and perceived burden of caregivers.

METHODS

Subjects comprised 100 caregivers of disabled children, including 96 mothers, 2 fathers and 2 grandmothers. Questionnaires included demographic data for children and caregivers, sleep problems of children, and sleep quality (Pittsburgh sleep quality index (PSQI)) and perceived burden on caregivers (Japanese version of the Zarit Burden Interview (J-ZBI)). The sleep problems of children were evaluated according to the following five categories: "Problems initiating and maintaining sleep"; "Problems with sleep-related breathing"; "Problems with excessive somnolence"; "Problems with circadian rhythm"; and "Problems with sleep-related movement".

RESULTS

The children comprised 66 boys and 34 girls (age range, 1-17 years). Of these, 65 children could not sit up and 35 could. A total of 88 children were found to have one or more categories of sleep problems. The most common sleep problem was "Problems initiating and maintaining sleep" (64.8%), followed by "Problems with sleep-related movement" (59.1%). J-ZBI was significantly higher in caregivers of children with "Problems initiating and maintaining sleep". PSQI scores were significantly higher in caregivers of children with "Problems with sleep-related breathing" and "Problems with circadian rhythm". A significant correlation was identified between perceived J-ZBI and PSQI of the caregiver.

CONCLUSIONS

Increased focus on the sleep problems of disabled children is needed, particularly in relation to the sleep quality and perceived burden of caregivers.

Relação entre independência funcional e qualidade de vida na paralisia cerebral

INTRODUÇÃO: A paralisia cerebral (PC) pode limitar o desempenho de atividades funcionais e a qualidade de vida desses indivíduos. OBJETIVOS:Avaliar a relação entre independência funcional e qualidade de vida de crianças com paralisia cerebral. MATERIAIS E MÉTODOS: A amostra foi composta por 30 crianças com diagnóstico de PC. Para mensurar a qualidade de vida foi utilizado o Questionário de Saúde da Criança (CHQ-PF50) e, para avaliar a funcionalidade, a parte I (habilidades funcionais) do Inventário de Avaliação Pediátrica de Incapacidade (Pedi). O teste de correlação de Spearman foi utilizado para avaliar a relação entre essas variáveis. RESULTADOS: Foi encontrada correlação significativa entre os domínios de função física e limitação das atividades diárias graças aos aspectos emocionais e comportamentais com todas as áreas do Pedi (p < 0,05). O domínio de limitação das atividades diárias graças aos aspectos físicos e a percepção de saúde apresentaram relação com as áreas de autocuidado e função social (p < 0,05). A função global só apresentou relação significativa com o autocuidado, e a saúde mental apresentou relação inversa com a mobilidade (p < 0,05). CONCLUSÕES: Nenhum domínio do CHQ-PF50 apresentou forte correlação com as áreas do Pedi, o que mostra que esses questionários avaliam constructos diferentes. Tais resultados podem auxiliar no planejamento de estratégias de avaliação e intervenção para crianças com PC.

Genetic [corrected] insights into the causes and classification of [corrected] cerebral palsies

Cerebral palsy-the most common physical disability of childhood-is a clinical diagnosis encompassing a heterogeneous group of neurodevelopmental disorders that cause impairments of movement and posture that persist throughout life. Despite being commonly attributed to a range of environmental factors, particularly birth asphyxia, the specific cause of cerebral palsy remains unknown in most individuals. A growing body of evidence suggests that cerebral palsy is probably caused by multiple genetic factors, similar to other neurodevelopmental disorders such as autism and intellectual disability. Recent advances in next-generation sequencing technologies have made possible rapid and cost-effective sequencing of the entire human genome. Novel cerebral palsy genes will probably be identified as more researchers and clinicians use this approach to study individuals with undiagnosed neurological disorders. As our knowledge of the underlying pathophysiological mechanisms of cerebral palsy increases, so will the possibility of developing genomically guided therapeutic interventions.

Sleep in children with cerebral palsy: a review

Children with neurodevelopmental disabilities, such as cerebral palsy, are considered to be a population at risk for the occurrence of sleep problems. Moreover, recent studies on children with cerebral palsy seem to indicate that this population is at higher risk for sleep disorders. The importance of the recognition and treatment of sleep problems in children with cerebral palsy cannot be overemphasized. It is well known that the consequences of sleep disorders in children are broad and affect both the child and family. This review article explores the types and possible risk factors associated with the development of sleep problems in children with cerebral palsy and the impact of this disorder on the child and family. In addition, a brief summary of current diagnostic and treatment modalities is provided. Finally, the characteristics, diagnostic techniques, and management of sleep-related breathing disorders in children with cerebral palsy are discussed.

Causes and correlates of frequent night awakenings in early childhood

Night awakenings are a normative part of early development. In the first year, night awakenings are associated with birth order, feeding route, sleep aid use, sleep location, infant temperament and development, infant-parent attachment, family socioeconomics, and cultural norms. In the second year, additional factors build on these foundational features, including parenting practices and object attachment. As children grow, contextual factors like preschool entry or changes in family member status may influence the continuation or exacerbation of awakenings. Future research should consider the multitude of factors that influence not only awakenings but also parental perceptions, family dynamics, and cultural norms.

A pilot study evaluating an abbreviated version of the cognitive remediation programme for youth with neurocognitive deficits

PRIMARY OBJECTIVE

To determine the effectiveness of an abbreviated version of an established cognitive remediation programme for children with neurological disorders and attention problems in an outpatient setting.

METHODS AND PROCEDURES

Eighteen 6-15-year-old children diagnosed with neurological and attention difficulties completed a six-module training programme aimed at improving attention. This programme was a shorter version of the Cognitive Remediation Programme (CRP), which has been successfully implemented with children with neurocognitive deficits. Parents completed measures of their children's attention and children completed neuropsychological measures of attention.

MAIN OUTCOMES AND RESULTS

The programme was associated with improvement in several aspects of parent-reported attention and children's performance on tasks measuring attention.

CONCLUSIONS

The shortened version of the CRP shows promise as a brief treatment for attention problems in outpatient neurological populations. Future research should assess programme effectiveness using a control group, longer-term follow-up and teacher reports.

Análise do equilíbrio estático e de deformidades nos pés de crianças com paralisia cerebral

O presente estudo analisou, por meio de um sistema de baropodometria, os tipos de pé, a influência da visão no equilíbrio estático na postura ortostática e a distribuição da pressão plantar em 16 crianças, de 6 a 15 anos, com diagnóstico de paralisia cerebral. Os resultados indicaram que o pé valgo foi o mais comum dentre os tipos de paralisia cerebral estudadas, diparesia espástica, hemiparesia espástica direita, hemiparesia espástica esquerda e ataxia; o equilíbrio estático na postura ortostática de olhos vendados apresentou maior instabilidade do que quando com os olhos abertos; a distribuição de pressão plantar não apresentou significância estatística e não houve correlação significativa entre a idade e as variáveis de equilíbrio e de distribuição da pressão plantar. Desse modo, conclui-se que a visão é um fator importante no controle postural de crianças com paralisia cerebral.

The Cerebral Palsy Demonstration Project: a multidimensional research approach to cerebral palsy

Cerebral palsy is the most common cause of physical impairment in pediatrics. As a heterogeneous disorder in all its disparate aspects it defies a simplistic research approach that seeks to further our understanding of its mechanisms, outcomes and treatments. Within NeuroDevNet, with its focus on abnormal brain development, cerebral palsy was selected as one of the three neurodevelopmental disabilities to be the focus of a dedicated demonstration project. The Cerebral Palsy Demonstration Project will feature a multi-dimensional approach utilizing epidemiologic, imaging, genetics, animal models and stem cell modalities that will at all times emphasize clinical relevance, translation into practice, and potential synergies between investigators now segregated by both academic disciplines and geographic distance. The objective is to create a national platform of varied complementary and inter-digitated efforts. The specific research plan to enable this will be outlined in detail.

Validating the Cerebral Palsy Quality of Life for Children (CP QOL-Child) questionnaire for use in Chinese populations

The purpose of this study was to examine the psychometric properties of the Chinese version of Cerebral Palsy Quality of Life for Children (CP QOL-Child) questionnaire. We performed forward (into Chinese) and backward translation of the CP QOL-Child for: (1) the primary caregiver form (for parents of children with CP aged 4-12 years); and (2) the child self-report form (for children with cerebral palsy aged 9-12 years). Psychometric properties assessed included test-retest reliability, internal consistency, item discrimination, construct validity, and concordance between the forms of questionnaire. The Chinese CP QOL-Child was completed by 145 caregivers and 44 children. Excellent test-retest reliability and internal consistency were obtained. Item discrimination analysis revealed a majority of the items have moderate to good discriminating power. Confirmatory factor analysis demonstrated distinguishable domain structure as on the original English version. Significant associations were found between lower QOL and more severe motor disability. Consistent with the English version, the highest correlation between the primary caregiver and child forms on QOL was in the domain of functioning. Results of this study indicate that the Chinese CP QOL-Child appears to be valid for use in Mandarin-Chinese speaking children with cerebral palsy.
