Family-centred care for children and young people with cerebral palsy: results from an Italian multicenter observational study.

Background: Family­centred care (FCC) is recognized as the model of best practice for the provision of services for children who have physical disabilities and their families. Objective: To assess the overall perception of FCC provided in an Italian network of 17 rehabilitation services, as perceived by parents of children with cerebral palsy and professionals, and to explore whether children, families, service providers and service­related characteristics influence parent satisfaction regarding service provision in an FCC practice. Methods: The Measure of Processes of Care (MPOC­20) for parents/caregivers and the Measure of Processes of Care for Service Providers (MPOC­SP) for healthcare providers were used. For the purposes of the study, an ad hoc information form was developed to collect information concerning children, families, service providers and services. Results: A total of 382 parents/caregivers and 269 healthcare providers completed the MPOC questionnaires. Parents and service providers both identified the domains for enabling partnerships and interpersonal sensitivity as a strength, while the domain relating to general information was always scored the lowest. An advanced maternal age, being a single parent, being unemployed and having lower socio­economic status were factors identified as individually predictive of lower FCC scores on the MPOC­20. Higher intensity treatment, inpatient services, primary healthcare settings and settings identified with limited financial resources and reduced space/time for each family were other variables significantly associated with less favourable MPOC­20 ratings. Conclusions: The perception of FCC provided was fairly positive, with some areas of improvement, such as the domain of provision of information. Professionals should, therefore, provide better communication and take more time in giving information and attention to parents. Potential sources of variation in parent perceptions of FCC based on family characteristics and the organization of services highlight the importance the need to support services through the provision of greater financial and human resources.

A new scale for the assessment of performance and capacity of hand function in children with hemiplegic cerebral palsy: reliability and validity studies.

BACKGROUND: In hemiplegic children, the recognition of the activity limitation pattern and the possibility of grading its severity are relevant for clinicians while planning interventions, monitoring results, predicting outcomes. OBJECTIVE: Aim of the study is to examine the reliability and validity of Besta Scale, an instrument used to measure in hemiplegic children from 18 months to 12 years of age both grasp on request (capacity) and spontaneous use of upper limb (performance) in bimanual play activities and in ADL. DESIGN: Psychometric analysis of reliability and of validity of the Besta scale was performed. SETTING: Outpatient study sample METHODS: Reliability study: A sample of 39 patients was enrolled. The administration of Besta scale was video-recorded in a standardized manner. All videos were scored by 20 independent raters on subsequent viewing. 3 raters randomly selected from the 20-raters group rescored the same video two years later for intra-rater reliability. Intra and inter-rater reliability were calculated using Intraclass Correlation Coefficient (ICC) and Kendall's coefficient (K), respectively. Internal consistency reliability was assessed using Alpha's Chronbach coefficient. Validity study: a sample of 105 children was assessed 5 times (at t0 and 2, 3, 6 and 12 months later) by 20 independent raters. Each patient underwent at the same time to QUEST and Besta scale administration and assessment. Criterion validity was calculated using rho-Pearson coefficient. RESULTS: Reliability study: The inter-rater reliability calculated with Kendall's coefficient resulted moderate K=0.47. The intra-rater (or test-retest) reliability for 3 raters was excellent (ICC=0.927). The Cronbach's alpha for internal consistency was 0.972. Validity study: Besta scale showed a good criterion validity compared to QUEST increasing by age and severity of impairment. Rho Pearson's correlation coefficient r was 0.81 (P<0.0001). Limitations. Besta scales in infants finds hard to distinguish between mild to moderately impaired hand function. CONCLUSIONS: Besta scale scoring system is a valid and reliable tool, utilizable in a clinical setting to monitor evolution of unimanual and bimanual manipulation and to distinguish hand's capacity from performance.

The perception of involved professionals towards research feasibility and usefulness: lessons from the Multi-Site Trial on Efficacy of Constraint Induced Movement Therapy in Children with Hemiplegia.

BACKGROUND: In the last decades, the world of rehabilitation has been more and more calling for clear evidence to support intervention and numerous research programs have been developed. At stake, relatively little research on opinions and attitude of rehabilitation personnel involved in research conducted in real clinical settings has been carried out. AIM: To explore the opinion of professionals involved in a national clinical trial on research. DESIGN: Multicentre cross-sectional study. SETTING: 19 rehabilitation centres/services (4 research institutes, 15 local rehabilitation services). POPULATION: All professional participating to a multi-centre clinical trial on the effects of Constraint Induced Movement Therapy on children with hemiplegic cerebral palsy. METHODS: A 15-questions questionnaire inquiring feasibility, usefulness, products, costs, judgement and perceptions about clinical research in rehabilitation was administered. RESULTS: Among those working in one of the 19 rehabilitation centres part of the multicentric study, 76 professionals were asked to fill in the questionnaire. 68 professionals answered (89.4% of response rate). More than 75% of the sample thinks that its rehabilitation centre is suited to develop clinical research. Research results useful for the development of their daily activities (new tools for the assessment of children, to demonstrate the efficacy of a new treatment option and to learn a new way of working, and to strengthen the ties within the working team). Research is costly in terms of personal time and effort, but it can modify the rehabilitation praxis (assessment tools, the relationship with colleagues/patients). 98% of the interviewees declared the willingness to participate to other research projects. CONCLUSION AND CLINICAL REHABILITATION IMPACT: This survey highlights the importance of conducting research in local rehabilitation services, not only in terms of generation of new evidences, but also in terms of building networks, sharing experiences and knowledge, connecting with centers of excellence and providing a specific training for research conduction.

The heel-contact gait pattern of habitual toe walkers.

We used kinematic, kinetic and EMG analysis to compare the spontaneous heel-contact gait patterns of 13 children classified as habitual toe walkers (HTWs) and age-matched controls. In the HTWs, the incidence of spontaneous heel-contact strides during a single recording session ranged from 15% to 92%, with no correlation with age, passive ankle joint excursion, walking speed and trial order. Hallmarks of the heel-contact strides were premature heel-rise, reversal of the second rocker, relative shortening of the loading response and anticipation and enhancement of the electromyographic (EMG) activity normally observed in the triceps surae (TS) during the first half of the stance phase. This variant of the locomotor program is different from the walking patterns observed in normally developing toddlers and children with cerebral palsy (CP). It does not necessarily reflect a functional adaptation to changes in the rheological properties of the muscle-tendon complex.

Evolution of upper limb function in children with congenital hemiplegia.

Hand function deficits in hemiplegic children are a major cause of disability, but there is a lack of appropriate instruments for evaluating the evolution of this deficit over time and for verifying the efficacy of its treatment. We evaluated changes in upper limb function in relation to age and the course of individual rehabilitation treatment in 20 children (13 males and 7 females) who were first seen within the first four years of life and subsequently followed until a mean age of 13 years and four months (range, 11-17 years) in accordance with a diagnostic/rehabilitation program initiated in our division in 1989. All of the children were treated by us; those whose paretic upper limb functioned well were not treated in any specific or directed manner. The protocol involved a qualitative evaluation of the spontaneous use of the paretic hand and a quantitative evaluation of grip. Analysis of the results revealed an age-related global improvement over time, occurring within the first five years of life and more pronounced in terms of grip than spontaneous use. This finding makes our protocol more specific than those currently used because it more reliably establishes the real capacity to use the paretic hand in different situations of everyday life. The most important changes concerned the children with more impaired functional capacity, whereas the children who presented with good functional skill retained this capacity over time, thus confirming the initial decision not to treat them.

Developmental sequence of postural control in prone position in children with spastic diplegia.

The aim of this study was to assess the development of postural control in the prone position in children with spastic diplegia and triplegia, and determine the influence of clinical characteristics, visual acuity and cognitive performance on that development. We also analysed the relation between these early motor achievements in the prone position and the subsequent acquisition of motor competence in the sitting position. We followed 24 diplegic and triplegic children from before age 2 years (mean age 12 months) to mean age 41 months, videorecording motor behaviour every six months and abstracting acquisitions in alignment and balance using a standardised procedure. We confirm a developmental sequence of all the acquired movements in the prone position. 83.3% of the children completed the uprighting sequence in the sagittal plane, acquired good balance, and ability to rotate the head and trunk. 70.8% of the children (all but one of the diplegic children and none among triplegic children) acquired symmetric posture in the frontal plane and 83.3% reduced leg hyperextension. Development was not uniform, and at 12-18 months two groups began to emerge: diplegic children who rapidly achieved all or most of the steps in the sequence and had a favourable prognosis for subsequent motor development; and triplegic children who achieved these steps at a much slower rate or in some cases not at all and had a less favourable prognosis for future development. Diplegic children with normal visual acuity, and general quotient GQ>70 did better than triplegic children with compromised visual acuity and GQ<70. Acquisition of the full uprighting sequence in the prone position before the age of two related to the later acquisition of autonomous sitting.

Predictors of independent walking in children with spastic diplegia.

A prospective study was carried out to identify predictors of independent walking in 31 children with either spastic diplegia or triplegia, observed from the age of 9 to 18 months (mean, 11 months) and followed for a mean period of 30 months (range, 24 to 36 months). Mean age at most recent examination was 41 months (range, 36 to 54 months). We used an 18-item scheme to chart the acquisition, from the prone position, of prelocomotor, sitting, and locomotor skills. Examinations were conducted every 6 months and videotaped according to a standardized procedure. At latest assessment 18 (58%) of the 31 children had achieved walking, 7 (23%) independently and 11 (35%) with assistance; 13 (42%) did not achieve walking. Ambulatory status was related to developmental quotient and visual acuity: all the children who became independent walkers had normal visual acuity and in 86% of cases a normal general development quotient. Moreover, we found a significant correlation between the number of gross motor skills achieved and the rate of achievement before 2 years of age and ambulatory status at 3 to 5 years of age. Ability to put weight on the hands while prone and to roll from supine to prone position by 18 months of age were significantly related to independent walking, while ability to sit without support was predictive only at around 24 months of age.

Eye-movement disorders and visual-perceptual impairment in diplegic children born preterm: a clinical evaluation.

The visual-motor behaviour of 15 preterm diplegic children and 50 control children (age range 4 to 7 years) was recorded on video as they performed a visual-perceptual task (an adaptation of the Animal House subtest of the Wechsler Preschool Primary Scale of Intelligence). The following parameters were analysed and scored: time to perform task; omissions; figure-colour association; sequence direction; sequential scanning order; accuracy of fitting target; and number of anticipatory saccadic movements to next target. The ability of the control children to perform the task improved significantly with age, as measured by performance time, mistakes in sequence direction and scanning order, accuracy of target fitting, and number of anticipatory saccadic movements. The scores of children with diplegia were not related to age and were poorer overall than those of the control group. Children with diplegia made significantly more mistakes of sequence direction and scanning order, and significantly fewer anticipatory saccadic movements than the control group. These results indicate that visual-perceptual impairment in diplegic children born preterm is not attributable only to sensory visual loss and to fine manipulation difficulties but is also related to difficulties in eye movements and in using anticipatory control to process information.

MRI features of cerebral lesions and cognitive functions in preterm spastic diplegic children.

The aim of this study is to further clarify the relation between the pattern of cognitive impairment in spastic diplegic children born preterm and MRI features of cerebral lesions. The cognitive profile by Wechsler Scale of a sample of 30 children aged 6 years, 8 months to 14 years, 7 months was assessed, and the correlations between the Full Scale, Verbal, and Performance IQ and periventricular leukomalacia features on MRI were investigated. A significant difference was observed between the mean Verbal and Performance IQ, indicating a specific failure in the visuoperceptual functions of spastic diplegic children born preterm. Periventricular leukomalacia was detected in all children. The severity of ventricular dilatation, the degree and extent of white matter reduction, optic radiation involvement, and the thinning of the posterior corpus callosum correlated significantly with the Full Scale and Performance IQ: no correlation was observed between the Verbal IQ and any of the MRI features analyzed. In spastic diplegic children, an MRI examination between the ages of 1 and 2 years may be helpful in predicting a specific neuropsychological pattern of dysfunction and in defining an early intervention program.

A novel point mutation in a 3' splice site of the NADH-cytochrome b5 reductase gene results in immunologically undetectable enzyme and impaired NADH-dependent ascorbate regeneration in cultured fibroblasts of a patient with type II hereditary methemoglobinemia.

Hereditary methemoglobinemia with generalized deficiency of NADH-cytochrome b5 reductase (b5R) (type II) is a rare disease characterized by severe developmental abnormalities, which often lead to premature death. Although the molecular relationship between the symptoms of this condition and the enzyme deficit are not understood, it is thought that an important cause is the loss of the lipid metabolizing activities of the endoplasmic reticulum-located reductase. However, the functions of the form located on outer mitochondrial membranes have not been considered previously. In this study, we have analyzed the gene of an Italian patient and identified a novel G-->T transversion at the splice-acceptor site of the 9th exon, which results in the complete absence of immunologically detectable b5R in blood cells and skin fibroblasts. In cultured fibroblasts of the patient, NADH-dependent cytochrome c reductase, ferricyanide reductase, and semidehydroascorbate reductase activities were severely reduced. The latter activity is known to be due to b5R located on outer mitochondrial membranes. Thus, our results demonstrate that the reductase in its two membrane locations, endoplasmic reticulum and outer mitochondrial membranes, is the product of the same gene and suggest that a defect in ascorbate regeneration may contribute to the phenotype of hereditary methemoglobinemia of the generalized type.

Prospective study of gross motor development in children with SMA type II.

The natural history of SMA and the identification of predictive criteria of functional development are still a matter of discussion. This prospective study involved 20 children with SMA, aged between 3.10 and 15.7 years. The patients were followed from 1979 to 1992 in order to try to develop a greater understanding of the natural history of SMA at a very early age. A standardized protocol was used at regular intervals to assess parameters such as joint contractures, scoliosis and the milestones of gross motor functions. Our findings agree with the data in the literature concerning the early and generalized onset of joint contractures and scoliosis. A significant correlation was found between the level of acquired gross motor functions and walking with support. The acquisition of rolling by 5 years of age was the milestone that best correlated with the acquisition of walking with crutches and braces; furthermore the inability to roll seemed to correlate with the severity of the disease. These findings should be useful in planning a more rational rehabilitation program.

The cognitive development of children born preterm and affected by spastic diplegia.

In a prospective study the intellectual development of 20 premature children affected by spastic diplegia was compared with that of 10 preterm low-risk children. The assessment was carried out with the Griffiths scale at the age of 3 years and with the WPPSI scale at the age of 6 years. The analysis of data collected in the 2 psychometric evaluations of the preterm-born diplegic children showed a disharmonic profile of neuropsychological functions, already present at the age of 3 years and confirmed at the age of 6 years. The average scores in diplegic children were poorest in the subscales locomotor, eye-hand coordination, and performance on Griffiths scale, and in the performance subtests of the WPPSI scale. The mean scores of subscales for hearing and speech, and practical reasoning on the Griffiths scale and of the verbal subscale of the WPPSI were near to the lower range of the normal distribution. Significant differences in performance subtests were found between the groups of preterm diplegic children and the group of low-risk preterm children, both at 3 and 6 years of age.

Clinical features and MR imaging in children with repaired myelomeningocele.

The aim of the study is to define the role of associated malformations in the clinical evolution of children affected by myelomeningocele. MRI investigation of the spinal cord was carried out on 25 patients between the age of 7.3 and 18.10 with MMC repaired and followed up for at least 7 years. The relation between associated malformations demonstrated by MRI and clinical trend was analysed. The results are the following: 1) presence of asymptomatic tethered cord in all cases; 2) high frequency (92%) of Chiari malformation; 3) presence of syringomyelia in 20% of patients, symptomatic in 1; 4) presence of ventricular enlargement in 72% of cases without increased intracranial pressure syndrome. For a better therapeutic approach prospective MRI studies are needed in order to follow up associated malformations.

Neurogenic arthrogryposis multiplex congenita: clinical and MRI findings.

A clinical and magnetic resonance imaging (MRI) study on a selected group of 11 children, with a diagnosis of neurogenic arthrogryposis multiplex congenita (AMC) based on clinical, electromyographic, and muscle biopsy findings, is presented to determine the extent of central nervous system involvement in AMC. Family history, pregnancy, perinatal problems, other abnormalities, and epileptic seizures were reviewed. Neurologic examination, electroencephalography, intellectual assessment, and MRI study both of spinal cord and brain were performed. The clinical and laboratory findings disclosed evidence of spinal cord lesions with involvement of anterior horn cell function in all patients, and impairment of cerebral function in 5 patients. MRI revealed spinal cord atrophy in 3 patients, diffuse atrophy in 2 patients, and involved thoraco-lumbar segments in 1 patient. Cranial MRI studies demonstrated features of developmental brain abnormalities in 3 patients, cortical frontal atrophy in 2, and was normal in 4. In neurogenic AMC patients, MRI examination of the spinal cord and brain may help to clarify the pathogenesis of the disease and is helpful for prognostic and therapeutic purposes.

Nosology of spastic tetraplegic cerebral palsy: clinical review of fifty cases.

The aim of this study is to contribute to the definition of tetraplegic cerebral palsy (TCP) and to verify the classification criteria currently used by reviewing the clinical and neurological aspects of 50 children having non-progressive encephalopathy with neurological involvement of 4 limbs (symmetric 4-limb type, side-asymmetric type, upper-limb dominated type with or without dystonic traits). All severe diplegic patients, i.e. less upper than lower limb involvement and patients with dystonic hyperkinetic syndrome without spastic features were excluded. The data were supplied by the hospital records, evolution of motor performance and the presence or absence of epilepsy, visual problems, language disorders, intellectual impairment. All the children underwent: neurological examination, functional assessment, cognitive evaluation. Severe motor impairment was found in 80% of the patients, whose clinical characteristics led to a diagnosis of severe TCP or "true TCP" according to Hagberg, whereas 20% of them showed mild to moderate impairment with a more favorable prognosis. This group of patients complied with the classification of Michaelis who defined the quadrispastic CP types more broadly and delineated five subgroups also including cases with milder involvement (side-dominated, three-limb dominated tetraparesis). The intellectual assessment showed that, in the severely affected patients, only a small percentage had severe intellectual impairment (IQ less than 50, 37.5%), which contrasts with published data on this pathology, while the majority of the subjects showed moderate (25%) or mild intellectual impairment (32.5%) or normal cognitive function (5%).(ABSTRACT TRUNCATED AT 250 WORDS)

Relation between CT patterns, clinical findings and etiological factors in children born at term, affected by congenital hemiparesis.

In order to examine if specific findings from CT correlate with specific clinical or neurological findings, 30 children, 5 to 16 years old, born at term, affected by congenital hemiparesis without intellectual impairment, were submitted to neurofunctional and psychological assessment and examined by CT. 28 of the 30 children had pathological CT. Two morphological CT patterns were found: A) Cavity in the cortex and underlying subcortical white matter (11 cases); B) Unilateral ventricular enlargement and paraventricular lesions (17 cases). CT was normal in two cases. In our children, born at term, no statistical correlation between CT patterns and anamnestic data was found as described in other studies, although in the patients with cortical-subcortical lesions, there was a slight prevalence of a history of perinatal complications, and in the patients with paraventricular lesions there was an uneventful history or abnormal pregnancy history. The relation between specific CT patterns (type A and B) and specific clinical dysfunction is not statistically evident, (unless for astereognosis and type A CT pattern). However, the patients with cortical-subcortical lesions showed a slight prevalence of a lower function of the impaired hand, and a higher percentage of an I.Q. of less than 90, than the group with unilateral ventricular enlargement. No relation was found between CT lesional pattern and epilepsy. The absence of correlation between morphological aspects and clinical findings could be explained by the complexity of structural changes and remodelling properties of the central nervous system, following prenatal and perinatal brain damage.

Clinical problems in neurodevelopmental diagnosis: a 7-year neurological and psychological follow-up study of low risk preterm infants.

24 selected urban middle class low risk preterm infants and 10 full term infants have been followed up to the age of 7 years in a prospective neurodevelopmental study. The aim was to find out whether the neurological and behavioral peculiarities of the preterm infant fall within the range of variability of sign and function development or whether they are the clinical features of minor neurological dysfunction. The infants were assessed neurologically according to Amiel-Tison at 3, 6, 9 and 12 months of corrected age and by Touwen's examination for minor neurological dysfunction at 3, 5 and 7 years. They were assessed psychologically at 6, 9, 12 and 36 months on Griffiths' Developmental Scale and at 7 years on the Wechsler Bellevue Scale. 33% of the sample was lost to follow-up. The outcome of neurological assessment was as follows: no major sequelae such as cerebral palsy or mental deficiency; 50% had transient neurological anomalies (TNA) during the first year of life, lasting more than 6 months in 16.7%; no minor neurological dysfunctions were detected at 5 and 7 years but the non optimal signs scores were higher in infants of low gestational age. The scores on the Griffiths scale were poorer in the preterm infants between 6 months and 5 years of corrected age, especially in the performance and hearing-speech areas. Performance failures seemed to be related to the duration and type of TNA in the first year of life. General, verbal and performance quotients on the WISC at 7 years were normal and there were no learning or behavior problems. The mild TNA found in low risk preterm infants in the first year of life appear to be of no predictive value for school age problems.

Neurological and psychological development of low-risk preterm infants in the first year of life.

Twenty-four selected low-risk preterm and 10 full-term infants were followed in a prospective study of the evolution of neurological signs in the first year of life and to consider the prognostic value of transient neurological abnormalities in relation to learning disabilities at school age. We report the results of the assessments made during the first 12 months. The assessment at 3, 6, 9 and 12 months was made using the Amiel-Tison neurological schedule and the Griffiths developmental scale. A high percentage of our low-risk premature infants (69% of 37-34 weeks gestational age and 75% of 33-27 weeks gestational age group) showed transient neurological anomalies, whereas no major neurological sequelae, i.e., cerebral palsies or mental impairment, were found. Moreover, in our series, the syndrome of transient dystonia associated with low birth weight, already described by other authors in samples not selected for risk, was not observed. The psychological development of all our infants was within normal limits at every assessment. Nevertheless, a significantly decreased performance at the sixth month in both preterm groups, particularly in the group of low gestational age, was found, and its significance will be clarified by further follow-up studies of early school age.

Functional evaluation of Duchenne muscular dystrophy: proposal for a protocol.

A protocol for the evaluation of functional activities in subjects with Duchenne muscular dystrophy (DMD) was designed. The aim of our study was to define objective clinical criteria for the evaluation both of the clinical status of the patient and of the natural history of the illness itself. A protocol with such criteria is particularly necessary when testing the efficacy of treatment. 43 still-ambulant children with DMD between the ages of 3.10 yr and 10.4 yr were examined. Of this number 19 children were evaluated every 4 months over a period of 12 months; of these 14 formed part of a randomized double blind trial with L-carnitine (1.2-1.8 g/day) versus placebo.
