Abstract

Custers JW, van der Net J, Hoijtink H, Wassenberg-Severijnen JE, Vermeer A, Helders PJ. Discriminative validity of the Dutch Pediatric Evaluation of Disability Inventory. Arch Phys Med Rehabil 2002;83:1437-41. Objective: To examine the discriminative validity of the Dutch Pediatric Evaluation of Disability Inventory (PEDI) to differentiate functional status between children with and without disabilities. Design: Cross-sectional study. Setting: A university children's hospital in the Netherlands. Participants: A clinical sample comprising 197 children with disabilities (infantile encephalopathy, n=40; juvenile idiopathic arthritis, n=20; neurometabolic conditions, n=36; neuromuscular disorders, n=9; skeletal disorders, n=28; spina bifida, n=41; traumatic injury, n=23), and 62 children without disabilities. Interventions: Not applicable. Main Outcome Measure: Functional status was measured by using a Dutch version of the PEDI. Results: Discriminant analysis established the sensitivity and specificity of the PEDI. Correct predictions of group membership (disabled vs nondisabled) were found in both children without disabilities (93.5% correctly predicted) and children with disabling conditions (91.6% correctly predicted). Conclusion: The discriminative validity of the Dutch PEDI between children with and without disabilities was excellent. © 2002 by the American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation

Participants

Between August 1999 and November 2000, 62 children without disabilities were recruited from a health care center for infants and toddlers (table 1).Parents visited this outpatient clinic for routine health assessment of their child. A clinical sample was measured between January 1999 and October 2000, comprising 197 children with different kinds of disabilities (table 1). Of them, 166 children were recruited from the University Children's Hospital and from an affiliated rehabilitation center,

Discussion

The aim of discriminative measures is to distinguish between individuals or groups on underlying dimensions.³ Discriminative measures in rehabilitation medicine are useful to determine the impact of a disorder with respect to functional status at a single point of time. The purpose of this study was to examine the discriminative validity of the Dutch-adapted PEDI, that is, the ability of the Dutch PEDI to discriminate between children with and without disabilities with respect to functional

Conclusion

This study confirmed that the Dutch PEDI has excellent discriminative validity with respect to functional status of daily activities of children with and without disabilities. The results establish the applicability of the PEDI for discriminative purposes in the patient groups used in this study. Therefore, the PEDI can serve as a diagnostic tool for professionals in pediatric rehabilitation medicine.

Use and functioning of the affected limb in children with unilateral congenital below-elbow deficiency during infancy and preschool age: A longitudinal observational multiple case study
2013, Early Human Development
Citation Excerpt :
In the PEDI-NL the ability to accomplish the activity is evaluated, regardless of whether or how the arms and hands are used. The discriminative validity of the PEDI-NL between children with and without disability, the inter-interviewer reliability (ICC 0.99), test–retest reliability (ICC 0.91–0.98) and inter-respondent reliability (ICC 0.91–0.99) are good [13,14]. The behavioural scores of the affected arm during standardized play over time of the four children were summarized in graphs, which were analysed visually.
Children with unilateral congenital below elbow deficiency (UCBED) lack a part of an arm, thereby lacking a part of the typical hand function. Little is known on the performance of daily activities in very young children with UCBED, usage of their affected arm with or without prosthesis during play, and neurological condition.
To explore daily activities, the use of the affected limb with or without prosthesis and neurological condition over time in young children with UCBED.
A longitudinal observational multiple case study.
Four children with UCBED were assessed (first assessment at 3–16 months) every 6–8 months (follow-up 13–49 months) with a video-recorded, standardized play session and a neurological examination. Yearly, functioning in daily activities was evaluated using the Pediatric Evaluation of Disability Inventory — Dutch Version (PEDI-NL). Play behaviour was assessed with and without prosthesis, where applicable (n = 2). Video-analysis focused on achievement, exploration, variation and adaptability of the affected limb. Behavioural changes over time were plotted and analysed visually.
Over time, children with UCBED showed efficient usage of their affected arm during spontaneous play. Prosthesis use seemed to be associated with reduced manipulation, exploration, variation and adaptation. Three children showed minor neurological dysfunction. Functioning in daily activities was comparable to a norm population.
The short limb of children with UCBED is used as an exploratory, manipulatory and fixating tool from the beginning of infancy. Its value seems to be reflected in these children's normal functioning in daily life. Prosthetic use may lead to less effective performance.
Skeletal effects and functional outcome with olpadronate in children with osteogenesis imperfecta: A 2-year randomised placebo-controlled study
2004, Lancet
Citation Excerpt :
For assessment of muscle strength with a hand-held myometer (CIT Technics BV, Groningen, Netherlands), measurements of maximum isometric force were made in triplicate and the highest values of abductor and grip strength of shoulder and hand, respectively, and flexor strength of the hip were used for analysis and were compared with normal values for children of the same age.20 Functional abilities in relation to self-care and mobility and the amount of assistance by a carer were quantified with the standardised and validated paediatric disability inventory.21–24 Anthropometric variables were body and seated height, arm span, head circumference measured to the nearest 0·1 cm, and bodyweight accurate to 100 g. Standard lateral radiographs of the spine were examined at a magnification of 100% for the measurement of anterior, posterior, and middle heights of each lumbar vertebral body (L1-L4).
Non-randomised studies have suggested beneficial effects of bisphosphonates in osteogenesis imperfecta. We assessed the effects of oral olpadronate in children with this disorder in a randomised double-blind placebo-controlled trial.
34 children recruited from the Dutch national centre for osteogenesis imperfecta were randomly assigned olpadronate (10 mg/m² daily; n=16) or placebo (n=18) for 2 years. All children also received calcium and vitamin D supplements. Primary endpoints were incident fractures of long bones and changes in bone mineral content (BMC), bone mineral density (BMD), and functional outcome. Anthropometry, vertebral height, and urinary markers of bone resorption were also studied. Analyses were by intention to treat.
Fracture follow-up was complete for all the children, including two who withdrew from the study (one from each group). Olpadronate treatment was associated with a 31% reduction in relative risk of fracture of long bones (hazard ratio 0·69 [95% CI 0·52–0·91], p=0·01). The olpadronate group showed significantly greater increases than the placebo group in spinal BMC (difference between groups 2·24 g/year [0·20–4·29], p=0·03) and spinal BMD (difference between groups 0·054 g/cm² per year [0·012–0·096], p=0·01). There were no detectable effects on functional outcome, anthropometrics, or vertebral height and no differences between the groups in changes in urinary markers of bone resorption.
Oral treatment with olpadronate at a daily dose of 10 mg/m² results in a reduction of fracture risk of long bones in children with osteogenesis imperfecta. However, the issue of whether bisphosphonates will alter the natural course of osteogenesis imperfecta remains unresolved, and further studies are needed.
Assessment of the impact of disease on the individual
2003, Best Practice and Research: Clinical Rheumatology
From the medical or disease perspective, patients’ functioning, disability and health are seen primarily as the consequences or the impact of a disease or condition. In this perspective, self-administered health status instruments are used primarily to evaluate the effects of drug treatments or surgical interventions. The interpretation of these measures is generally based on scales and scores and not on individual items. Currently used instruments are reviewed and an algorithm for the selection of instruments is provided.
In the rehabilitation or disability perspective, patients’ functioning and health is associated with and not merely a consequence of, a condition or disease. The basis for the understanding of functioning, disability and health—in association with the condition but also the personal and contextual factors—is WHO's International Classification of Functioning, Disability and Health or ICF. This chapter illustrates the use of the ICF framework for structuring patients’ problems, and the use of condition-specific ICF-Core-Sets to check for problems typically encountered in patients with a given condition.
