How well are we doing? Families of adolescents or young adults with cerebral palsy share their perceptions of service delivery.

PURPOSE: The satisfaction of families of adolescents and young adults with a diagnosis of cerebral palsy with the service delivery they had experienced in the areas of health, education, recreation, employment, housing and transportation was examined. Common themes across the six service areas were identified. METHOD: Forty-nine adolescents (13-15 years) and 39 young adults (19-23 years) and their families rated their satisfaction with services and then participated in semi-structured interviews to discuss their experiences. RESULTS: Using a constant comparative method of analysis, common themes were identified from the transcribed interviews. Four themes were identified and named: caring and supportive people; fighting and fatigue; communication/information; and disability awareness. CONCLUSIONS: Families continue to experience dissatisfaction and frustration with service delivery in the six areas examined. Both bureaucratic structure and attitudes of service providers contribute to their dissatisfaction.

Changing philosophical perspectives on the management of children with physical disabilities--their effect on the use of powered mobility.

PURPOSE: Over the past decade, the emergence of a new philosophical framework has influenced approaches to service delivery in paediatric rehabilitation. Traditional approaches focused on the attainment of typical movement patterns as the ultimate goal of intervention. By contrast, contemporary approaches to intervention encourage children with physical disabilities to use their most efficient movement strategies to explore their environment and participate in meaningful activities. METHODS/RESULTS: Factors that facilitated this change in approaches to intervention are explored and include: the disability movement; the evolution of models of disablement; the shift from a medical model to a family-centred model of health care service provision; the emergence of a new theory to explain motor development and increased availability and quality of assistive technology. CONCLUSION: The clinical implications of this philosophical shift for the use of powered mobility with children with physical disabilities are explored. A collaborative approach to working with families throughout the process of selecting mobility options for their children is discussed.

Are families with adolescents and young adults with cerebral palsy the same as other families?

This study compared adolescents with cerebral palsy (CP) and their families to adolescents without physical disabilities and their families as the child enters and leaves adolescence (age ranges 13 to 15 years and 19 to 23 years). Families of 90 individuals with CP (42 females, 48 males) and 75 individuals without physical disabilities (34 females, 41 males) participated. They completed the Family Assessment Device, Life Situation Survey, Multidimensional Scale of Perceived Social Support, and Future Questionnaire. There were few differences in family functioning, life satisfaction, or perceived social support between the groups. Expectations of young adults with CP and parents of both adolescents and young adults regarding future independence and success were lower than the expectations of the control group. While the group results emphasize similarities between families during the two stages of adolescence, individual families and individual family members report specific challenges.

Inter-rater reliability of formally trained and self-trained raters using the Edmonton Functional Assessment Tool.

The primary objective of this study was to determine the inter-rater reliability of the revised version of the Edmonton Functional Assessment Tool (EFAT-2). A second objective was to determine whether both formally trained and self-trained therapists had an acceptable level of inter-rater reliability. The EFAT-2 was administered to consenting palliative care patients by one of two independent physical therapist rater pairs; one pair self-trained (R1, R2) and the other formally trained (R3, R4). The intraclass correlation [ICC (1,1)] for R1, R2 was 0.97 [95% confidence interval (CI) 0.94-0.99] and for R3, R4 was 0.95 (95% CI 0.90-0.98). The standard error of measurement was 1.09 and 1.44, respectively. The Kappa statistic for the rater pairs on individual EFAT items ranged from 0.17 to 0.96. The results suggest that both formally trained and self-trained therapists obtain an acceptable level of inter-rater reliability when using the EFAT-2.

Intra-individual stability of rate of gross motor development in full-term infants.

The purpose of this study was to evaluate the intra-individual stability of gross motor scores obtained by normally developing full-term infants on the Alberta Infant Motor Scale (AIMS). The gross motor skills of 47 infants were assessed monthly in their homes by pairs of physical therapists. Infants were followed from two weeks of age until they achieved independent walking. A developmental pediatrician assessed each infant at 18 months of age, and classified the infant's gross motor skills as normal, suspicious or abnormal. Only the data of infants receiving a normal classification at 18 months were included in the analyses (n = 45). Individual infants' percentile ranks varied considerably from month to month, with no systematic pattern of change noted across infants. As a group, the mean percentile range over 13 assessments was 66.78 (S.D. 13.47). Fourteen infants (31.1%) received a score below the 10th percentile on at least one occasion. The results suggest that normally developing infants are not stable in the rate of emergence of gross motor skills. This instability has implications for infant screening programs, and supports the premise of serial assessments to identify accurately those infants with a motor delay.

Assessment of gross motor skills of at-risk infants: predictive validity of the Alberta Infant Motor Scale.

The Alberta Infant Motor Scale (AIMS) is a norm-referenced measure of infant gross motor development. The objectives of this study were: (1) to establish the best cut-off scores on the AIMS for predictive purposes, and (2) to compare the predictive abilities of the AIMS with those of the Movement Assessment of Infants (MAI) and the Peabody Developmental Gross Motor Scale (PDGMS). One hundred and sixty-four infants were assessed at 4 and 8 months adjusted ages on the three measures. A pediatrician assessed each infant's gross motor development at 18 months as normal, suspicious, or abnormal. For the AIMS, two different cut-off points were identified: the 10th centile at 4 months and the 5th centile at 8 months. The MAI provided the best specificity rates at 4 months while the AIMS was superior in specificity at 8 months. Sensitivity rates were comparable between the two tests. The PDGMS in general demonstrated poor predictive abilities.

The use of waterbeds for very low-birthweight infants: effects on neuromotor development.

One hundred and seven infants aged < 32 weeks of gestation were stratified according to birthweight and randomly assigned to either a waterbed group (N = 53) or a mattress group (N = 54). All the infants were assessed on removal from the surface: 68 infants at 40 weeks gestation and 52 infants at four, eight, 12 and 18 months adjusted age. At the 18-month assessment, outcome was classified as normal, suspicious or abnormal. There were no significant differences between the groups at any age. The results suggest that the use of the waterbed as a positional surface in the neonatal intensive-care unit has no influence on the motor development of very low-birthweight infants.

Early developmental screening: sensitivity and specificity of chronological and adjusted scores.

The motor development of 75 preterm infants was assessed at 4 months chronological and 4 months adjusted ages using the Movement Assessment of Infants (MAI). Infants were followed until 18 months old when neurological and motor outcomes were assessed by a developmental pediatrician, and outcomes were classified as normal, suspicious, or abnormal. Sensitivity, specificity, and positive and negative predictive values were calculated at the two points in time using a variety of cutoff MAI scores. At 4 months, the practice of adjusting for prematurity resulted in the better combination of screening rates for the detection of both neurologically abnormal and neurologically abnormal/suspicious children. To obtain comparable rates, different cutoff MAI scores were used to identify the neurologically abnormal versus the neurologically abnormal/suspicious children. The optimal combination of sensitivity, specificity, positive and negative predictive values varies according to the age of assessment, the disorders being identified, and the cutoff scores employed.

Serial magnetic resonance imaging in neonatal hypoxic-ischemic encephalopathy.

We prospectively performed magnetic resonance imaging (MRI) studies during the neonatal period, and at 4 and 8 months of age, on 15 term infants with hypoxic-ischemic encephalopathy, and compared the results with their neurodevelopmental outcome at 18 months of age. Cerebral palsy developed in nine infants, two infants were classified as having abnormalities of tone and delayed motor milestones that were suggestive of cerebral palsy, and four infants were normal. Structural abnormalities, delayed myelination, or a combination of the two were detected with MRI at 8 months of age in all nine infants with later development of cerebral palsy. Three of the four normal infants and one infant with suggestive abnormalities had normal serial MRI findings. Each of the remaining two infants (one normal, one with suggestive abnormalities) had isolated persistent ventricular dilation on all three MRI studies. Our results suggest that 8 months appears to be the earliest time at which MRI findings correlate well with later adverse neurodevelopmental outcome in this population.

Gross and fine motor development of preterm infants at eight and 12 months of age.

Forty-five neurologically normal preterm infants were allocated to one of two groups according to their gestational age at birth (less than 32 weeks; 32 to 36 weeks). Their gross and fine motor development was assessed at eight and 12 months chronological age and eight and 12 months adjusted age. At eight months chronological age the two groups differed significantly in both gross and fine motor development, but at eight and 12 months adjusted age and 12 months chronological age they differed significantly only in fine motor development.

Motor development at term of very low birthweight infants with bronchopulmonary dysplasia.

Forty-one preterm infants weighing less than 1500 g and less than 32 weeks' gestation at birth had a Dubowitz neurological assessment performed at 40 weeks postconceptional age. The infants were classified into three groups. Eight infants had bronchopulmonary dysplasia and severe central nervous system abnormalities, 11 infants had bronchopulmonary dysplasia alone, and 22 infants had neither bronchopulmonary dysplasia nor severe central nervous system abnormalities. The neuromotor performance of these three groups of infants was similar on all the Dubowitz assessment items at 40 weeks postconceptional age. Neuromotor development of very low birthweight infants with severe bronchopulmonary dysplasia appears to be no different from that of infants without bronchopulmonary dysplasia at 40 weeks postconceptional age utilizing the Dubowitz neurological assessment.

Mucinous colon carcinoma in a black family.

Carcinoma of the large bowel developed in an autosomal dominant pattern in 13 members of a black-American family. Seven members were affected prior to initial ascertainment of the family in 1976. Thereafter, the remaining six were affected while 0.2 cases were expected (p less than 0.001). Median age at diagnosis of colon cancer was 39 years (range, 22-62 years) in this family, compared with 65 years among black-Americans, in general. Histologic review of surgical specimens from six patients and medical record data for a seventh patient showed mucinous adenocarcinoma of the colon, an uncommon histologic variant. Studies of several family members a decade ago had revealed no biologic markers of cancer susceptibility.
