Specific language deficiencies in children with early onset hydrocephalus

Specific language abilities of children with early onset hydrocephalus were compared to nonhydrocephalic comparison groups. Ninety children, aged 5 to 7 years, composed six subject groups: three groups having a history of hydrocephalus due to spina bifida, prematurity-intraventricular hemorrhage, or aqueductal stenosis. and three comparison groups of children with spina bifida who had never been shunted, premature children with no hydrocephalus, and normal controls. Group performance scores were compared on measures of phonological awareness, semantics, fluency, and word retrieval. Children with hydrocephalus performed below their peers on all measures. These results indicate that early onset hydrocephalus has a substantial adverse impact on the development of a wide range of specific language abilities.     

Impairment of a motor skill in children with spina bifida cystica and hydrocephalus: an exploratory study.

Twenty 7-10 year old children with spina bifida cystica and hydrocephalus and 20 normals matched for age, sex and IQ were compared on a 12-trial target task, first used by Connolly, Brown & Bassett (1968). Analysis of the results, in which particular attention was paid to statistical method and to ways of analysing individual differences, showed a significant impairment in dotting speed in the spina bifida group, although both groups improved with practice. In a second experiment immediately following the first, visual monitoring of this task was restricted. The spina bifida children were initially more affected than the controls but able to recover. The findings are discussed in relation to neurological abnormalities in the spina bifida group.     

Children with spina bifida perceive visual illusions but not multistable figures

We compared 32 children with spina bifida and 32 age-matched controls on two classes of illusory perception, one involving visual illusions and the other, multistable figures. Children with spina bifida were as adept as age peers in the perception of visual illusions concerned with size, length, and area, but were impaired in the perception of multistable figures that involved figure-ground reversals, illusory contours, perspective reversing, and paradoxical figures. That children with spina bifida reliably perceive illusions that rely on inappropriate constancy scaling of size, length, and area suggests that their brain dysmorphologies do not prevent the acquisition of basic perceptual operations that enhance the local coherence of object perception. That they do not perceive multistable figures suggests that their visual perception impairments may involve not object processing so much as poor top-down control from higher association areas to representations in the visual cortex.     

Visual but not spatial working memory deficit in children with spina bifida

Twenty children with spina bifida and twenty controls were assessed on a battery of visuospatial working memory tests. Children with spina bifida performed as well as the control group in the visuospatial test and in the forward and backward versions of the Corsi test, but were impaired in the 'House Visual Span.' This test, designed in our lab, provides specific information regarding visual ability to discriminate between pictorial targets and lures, and requires specific visual processing of stimuli. These results are discussed in terms of working memory models and are viewed as supporting the distinction between the visual and spatial components of working memory.     

Assessing the factorial invariance of Harter's self-concept measures: comparing preadolescents with and without spina bifida using child,parent, and teacher report

The purpose of this study was to determine whether the structure of children's self-concept, as rated by children themselves on the Self-Perception Profile for Children (SPPC; Harter, 1985), and the structure of children's competence, as rated by their parents on the Rating Scale of Child's Actual Behavior (PRS) and teachers on the Rating Scale of Child's Actual Behavior (TRS; Harter, 1985), are similar across samples of children with and without spina bifida (children were 8 and 9 years of age; n = 68 in each sample). Using confirmatory factor analyses, results revealed that a multidimensional model for the SPPC and the TRS fit the data well for both samples. On the other hand, the model for both mothers' and fathers' PRS ratings did not fit the data for the spina bifida sample. Further tests of factorial invariance conducted on the SPPC and TRS revealed that the spina bifida and able-bodied samples tended to have the same pattern and magnitude of factor loadings for both instruments. There was some invariance, however, in the amount of unique error variance accounted for across samples. These results bolster our confidence in using the SPPC and TRS to compare children with and without spina bifida.     

Executive functioning and psychological adjustment in children and youth with spina bifida

Children and adolescents with spina bifida are at risk for poor neuropsychological functioning and psychological outcomes. The relationship between executive functioning and psychological adjustment is an area worthy of investigation in this population. The current study assessed executive functioning and psychological outcomes in a group of children and adolescents with spina bifida (SBM) (n = 51) and nondisabled controls (n = 45). A mediation model was hypothesized, such that Metacognition, as measured by the Behavior Rating Inventory of Executive Function (BRIEF), mediated the relationship between group status (spina bifida versus nondisabled controls) and psychological outcomes. Results indicated that metacognitive skills fully explained the relationship between group and internalizing and depressive symptoms as reported by mothers. In particular, specific components of the BRIEF Metacognition composite were most responsible for this relationship, including Initiate, Working Memory, and Plan/Organize. The study limitations include its cross-sectional nature that precludes drawing conclusions about causality. The results have implications for treatment interventions for children and adolescents with spina bifida and typically developing individuals.     

Idiom comprehension deficits in relation to corpus callosum agenesis and hypoplasia in children with spina bifida meningomyelocele

Idioms are phrases with figurative meanings that are not directly derived from the literal meanings of the words in the phrase. Idiom comprehension varies with: literality, whether the idiom is literally plausible; compositionality, whether individual words contribute to a figurative meaning; and contextual bias. We studied idiom comprehension in children with spina bifida meningomyelocele (SBM), a neurodevelopmental disorder associated with problems in discourse comprehension and agenesis and hypoplasia of the corpus callosum. Compared to age peers, children with SBM understood decomposable idioms (which are processed more like literal language) but not non-decomposable idioms (which require contextual analyses for acquisition). The impairment in non-decomposable idioms was related to congenital agenesis of the corpus callosum, which suggests that the consequences of impaired interhemispheric communication, whether congenital or acquired in adulthood, are borne more by configurational than by compositional language.     

Impact of Spina Bifida on Parental Caregivers: Findings from a Survey of Arkansas Families

The well-being of caregivers of children with spina bifida and other conditions is an important topic. We interviewed the primary caregivers of 98 children aged 0–17 years with spina bifida sampled from a population-based birth defects registry in Arkansas and the caregivers of 49 unaffected children. Measures of caregiver well-being were compared between the groups and by level of lesion (sacral, lower lumbar, and upper lumbar/thoracic). We performed linear and logistic regression analysis to test the associations controlling for other characteristics. Among caregivers of children with spina bifida, the average number of hours of sleep was significantly less than reported by other caregivers and was associated with lesion level among children less than 7 years of age. Significant associations, often varying by child age, were also found for the caregiver’s reports of lower Quality of Well-Being (QWB) score, often feeling blue, rarely feeling happy, fair or poor health, lack of leisure days, and not hosting friends, but no significant association was found with not visiting friends. The intensive long-term care required by children with spina bifida, particularly by those with higher lesions, can negatively impact caregiver health and well-being. Support for these caregivers is needed.     

Factors of biological risk and reserve associated with executive behaviors in children and adolescents with spina bifida myelomeningocele.

This study examined differences between healthy children (n = 35) and those with spina bifida myelomeningocele (SBM; n = 42) on the Behavior Rating Inventory of Executive Function (BRIEF), a measure of executive function behaviors. It also examined whether aspects of biological risk associated with SBM and reserve factors within the family could account for variability in BRIEF scores for children and adolescents with SBM. Patients in the SBM group exhibited more problems than both published norms and a local comparison group of healthy children in metacognition but not behavior regulation. Behavior regulation problems in children with SBM were predicted by parent psychological distress. More shunt-related surgeries and history of seizures predicted poorer metacognitive abilities.     

Psychiatric Symptomatology and Family Functioning in Children and Adolescents with Spina Bifida

The purpose of this study was to (a) examine the occurrence of psychiatric symptomatology in children and adolescents with spina bifida, (b) investigate the relationship between psychiatric features and aspects of disability, and (c) explore the impact of spina bifida and psychiatric status on family functioning. Fifty-four children and adolescents ages 6 to 18 years (M = 12.94, SD = 3.59) were examined. Parents completed the Child Symptom Inventory (CSI) and the Family Assessment Device (FAD). Using the CSI, a psychiatric diagnostic screen, 43% of the sample obtained one, and 13% obtained two or more screening cutoff scores reflective of psychiatric diagnoses. The two most prevalent diagnostic categories were Attention-Deficit/Hyperactivity Disorder (33%) and Oppositional Defiant Disorder (13%). The sample as a whole exhibited elevated levels of clinical symptoms, with internalizing symptoms more prominent than externalizing symptoms. No differences in diagnostic categories or overall symptomatology were found based on age, gender, ambulation status, or lesion level. Overall symptom counts were positively correlated with scales on the FAD reflecting problematic family functioning (.42–.65). Results suggest that psychiatric symptomatology occurs at a high rate in children and youth with spina bifida. Although ADHD was the modal diagnostic category, the sample as a whole exhibited extensive psychiatric symptoms independent of specific diagnostic categories. Psychiatric symptoms were also associated with increased problematic functioning in families.     

The influence of juggling on mental rotation performance in children with spina bifida

This study examined the influence of juggling training on mental rotation ability in children with spina bifida. Children between the ages of 8 and 12 solved a chronometric mental rotation test. Half of the children received juggling training (EG) over an 8week time period; the other half did not receive training (CG). Afterwards, all participants completed the mental rotation test again. Children of the EG showed a significant decrease in reaction time and an increase in mental rotation speed compared to the control group. This indicates that juggling improves the rotation in the mental rotation process in children with spina bifida.     

Neuropsychological and adaptive functioning in younger versus older children shunted for early hydrocephalus

Previous research on children with hydrocephalus has not carefully examined age-related changes in neuropsychological and behavioral status. We present data on 28 children with early hydrocephalus and spina bifida who were studied in two age groups: 5 - 7.5 and 9 - 12.5 years. Age-related differences in language, memory, visuomotor skills, and adaptive behaviors were examined. Consistent with other studies, the total sample showed impaired motor, performance, verbal, communication, and learning skills. Comparisons between older and younger children showed: (1) except for memory, neuropsychological patterns of functioning were generally comparable across the age groups, and (2) older children demonstrated more difficulty on specific adaptive functions (socialization, learning, conduct). Shunted hydrocephalic children may be conceptualized as exhibiting the syndrome of nonverbal learning disabilities. Clinical implications are discussed.     

Optimism,appraisals, and coping in the adjustment of mothers and their children with spina bifida

Families of children with physical disabilities show substantial differences in the levels of adjustment of both the children and their parents. These differences result, in part, from the complex interplay of family and child adaptation resources, such as coping and social support. In order to identify factors which may differentiate levels of adjustment among families with children with physical disabilities, this study examined relationships among optimism, primary and secondary appraisals of and coping with child-related stressors, maternal psychological adjustment, and child adjustment in 29 families with a child with spina bifida without mental retardation and 28 comparison families with a nondisabled child. For the spina bifida group, primary appraisals were related to the use of avoidant coping strategies, and these coping strategies were related to maternal psychological adjustment and child internalizing behavior problems. No significant differences between the groups in terms of the nature of the relationships or in the levels of the variables were found with the exception that mothers of children with spina bifida were less optimistic than comparison mothers. These data support the importance of coping in understanding the psychological adjustment of mothers faced with a chronic stressor in the family.

Reaching for Independence: Counseling Implications for Youth With Spina Bifida

Spina bifida, a congenital physical disability, is indirectly associated with difficulties in scholastic achievement, social development, and self‐determination. Environment can have an impact on psychosocial development and impede functioning academically, socially, and vocationally. Counselors must be aware of the societal atmosphere to identify potential difficulties and more efficiently meet the needs of children and adolescents with spina bifida.     

The structure and function of social support networks in families with handicapped children

Three structural characteristics of social support networks (size, density, and boundary density) and two relationship characteristics (reciprocity and dimensionality) were assessed in a sample of 56 families with a child with spina bifida and 53 matched comparison families. The results indicate that social networks of families with handicapped children tended to be smaller than the networks of comparison families, particularly with regard to mothers' total and friendship networks. The networks of families with handicapped children were more dense as well. As predicted, there was greater boundary density in spousal networks in families with handicapped children. Differences in network reciprocity were inconclusive while the results indicate that families with handicapped children tended to rely more heavily upon multidimensional network contacts than did comparison families. The results are discussed in light of our understanding of stress, social support, and the social ecological context of families.     

Evidence for spatial navigational impairments in hydrocephalus patients without spina bifida

The cognitive sequelae of hydrocephalus have mostly been explored with standardised clinical tasks. The aim of the present research was determine whether impairments on these abstract tasks extend to everyday spatial and navigational behaviour. Patients with hydrocephalus, but without spina bifida, were compared to a control group on tests of searching behaviour, landmark memory, route learning, and path integration. Participants with hydrocephalus displayed reduced sensitivity to spatial cueing, less accurate route-learning, and significantly less accurate spatial updating. These data represent an important empirical demonstration of spatial navigational impairments due to hydrocephalus outside of the context of spina bifida. We discuss some of the cognitive, neural, and individual differences factors that might contribute to this particular pattern of impairments.     

Spatial cognition and motor development: a study of children with spina bifida

The purpose of this study was to examine the relation between motor development and spatial cognition. The sample was 20 children with Spina bifida (M age: 11.4 yr., SD = 1.7) and 20 healthy children as controls (M age: 11.8, SD = 1.8 yr.). An experimental assessment of motor development in spatial cognition in a simulated virtual maze by school-age children is lacking. In this study children with Spina bifida, who were impaired in walking since birth, completed four visuospatial tasks in a small-scale space (Mental Rotation, Water-Level Task, Embedded Figures Test, Visual Short-term Memory Test), and a spatial behaviour and knowledge task in a virtual maze. These children showed poorer performance than children in the control group on most measures. The results are discussed with respect to theoretical implications and further research.     

Secondary conditions in children with disabilities: spina bifida as a case example

This paper examines the concept of secondary conditions and its application in studies of childhood disability focusing on children with spina bifida as a representative group. The "International Classification of Functioning, Disability and Health" (World Health Organization, Geneva, 2001) provides a classification of body function/structure, activities, participation and the environment to document dimensions of human functioning in context. The ICF is of value in the study of secondary conditions in two ways: as a conceptual framework for defining impairments, activity limitations and participation restrictions, and the mediating role of the environment in their expression; and as a taxonomy for coding these dimensions of disability. The ICF can yield a profile of a child's difficulties, and documentation of environmental barriers experienced by that child. Research studies with children and adolescents with spina bifida reveal that physical and mental impairments and limitations in performing activities and participating in communal life are experienced as secondary conditions. The significance of secondary conditions is that they are preventable. Identifying the mechanisms associated with their manifestation is thus an important priority for the development of effective prevention programs.     

Postural Stability in Children with High Sacral Level Spina Bifida: Deviations from a Control Group

Abstract

Objective: To assess static and dynamic postural stability changes in children with high sacral level spina bifida.

Methods: Thirty-five children with high sacral level spina bifida and 35 age-matched healthy controls were enrolled. Their lower extremity muscle strengths and static and dynamic postural stability parameters were measured with the use of a dynamometer and the NeuroCom Balance Master^® device, respectively. Functional gait and balance were evaluated using the five times sit-to-stand test (5STS) and the 6-minute walk test (6MWT). Spinal, hip, and ankle deformities of the patient group were measured by radiologic evaluation.

Results: In comparison with controls, patients were found to have lower ankle dorsiflexion and plantar-flexion strength, increased 5STS duration, and decreased 6MWT distance while both static and dynamic postural stability parameters were significantly different. Bilateral ankle muscle strengths were found to be negatively correlated with postural stability parameters. The presence of hydrocephalus or meningomyelocele in the patient group was found to have negative effects on static postural stability.

Conclusion: Static and dynamic postural stability is affected even in children with high sacral level spina bifida who are expected to have best condition in this patient population. The ankle muscle strength is the main factor influencing these changes.
