Hideshima Y, Asami T, Ichiba M, Matsuo K, Murata T. A study on the effectiveness of training in the operation of an electric mobility aid in severely mentally and physically handicapped children. Jpn J Compr Rehabil Sci 2024; 15: 8-16.

Purpose

We examined whether operation training for children with severe mental and physical disabilities using recently developed electric mobility aids improves their skills in operating such aids and their daily activities. By doing so, we aimed to clarify the effectiveness of electric mobility aid operation training for children with severe mental and physical disabilities.

Method

Operation training and normal training using an electric mobility aid were conducted for 42 school-aged children with severe mental and physical disabilities, aged 8-18 years old. The trainee children were randomly assigned to two groups: 21 to the intervention group to receive operation training and 21 to the control group to receive general training. The intervention lasted 20 minutes/training session, with three sessions/week over a period of eight weeks. The Powered Mobility Program (PMP) and Pediatric Evaluation of Disability Inventory (PEDI) were used for pre- and post-intervention assessments, and SPSS was used for two-way analysis of variance (ANOVA).

Results

PMP scaled scores significantly increased (p = 0.001) in both groups, but there was no interaction effect. The PEDI scaled scores did not significantly increase in either of the two groups.

Discussion

The effects of the intervention and use of the electric mobility aid on the operating skills of children with severe mental and physical disabilities were explicitly demonstrated. Future long-term studies are required to clarify the effects of training in the operation of electric mobility aids on the subsequent development of severely physically and mentally handicapped children.

Validity and test-retest reliability of the Ugandan version of the Pediatric Evaluation of Disability Inventory (PEDI-UG) in children and youth with cerebral palsy

BACKGROUND

Validity of the Ugandan version of the Pediatric Evaluation of Disability Inventory (PEDI-UG) was previously investigated on typically developing children. This study aimed to investigate the validity, test-retest reliability and minimal detectable change (MDC) of the PEDI-UG in children and youth (C&Y) with cerebral palsy (CP).

METHOD

A cross-sectional study design with 118 C&Y with CP (44.7% girls) aged 10 months-22.5 years were included in the study; 37 of them completed the PEDI-UG twice to investigate test-retest reliability, determined by calculating the intraclass correlation coefficient (ICC). Additionally, data from 249 typically developing children were used for differential item functioning (DIF) analysis. The validity of the PEDI-UG was investigated by Rasch analysis. The Kruskal-Wallis test and Spearman's correlation coefficient were calculated to investigate associations between PEDI-UG scores and external classification systems.

RESULTS

The principal component analysis of residuals indicated unidimensionality in all domains. The ICC values were excellent (0.98-0.99), and the MDCs were less than 6 and 13 (on a 0-100 scale) for the functional skills and caregiver assistance parts, respectively. The four-category caregiver assistance rating scale fulfilled the criteria for the analysis of rating scale functioning. In total, 78 of 189 items in the functional skills domain and two items in the caregiver assistance domain demonstrated DIF between C&Y with CP and TD children. The Kruskal-Wallis test (p < 0.05) and Spearman's correlation (coefficients of -0.93 to -0.78) supported the validity of PEDI-UG.

CONCLUSION

The current diagnose-specific version of PEDI-UG demonstrates evidence for validity as a measure of ability in C&Y with CP in Uganda and other similar settings, being a promising tool for use in clinical practice and research. Conversion tables and MDC values are provided to facilitate clinical adoption of the measure.

Evaluation of test-retest reliability and concurrent validity of the Italian version of the pediatric evaluation of disability inventory in children with down syndrome: A cross-sectional study

PURPOSE

Down Syndrome (DS) is a common genetic disorder caused by trisomy 21. Due to cognitive challenges associated with DS, individuals often experience difficulty performing activities of daily living (ADLs), at levels that can range from mild to significant. This study aimed to measure psychometric properties of the Italian version of the Pediatric Evaluation of Disability Inventory (PEDI-I) in the DS population.

METHODS

The PEDI-I was administered to children with DS. The internal consistency was examined using Cronbach's Alpha. Test-retest reliability was demonstrated by intraclass correlation coefficient (ICC) and Bland-Altman plots. The concurrent validity was evaluated with the Italian version of the Barthel Index.

RESULTS

The PEDI-I was administered to 54 children with DS. Cronbach's Alpha showed statistically significant values (0.899 -0.986). The ICC confirmed the reproducibility of the scale with a range of (0.988 -1), while Bland-Altman plots showed a smallest detectable change of (0.18-1.63). The Pearson Correlation Coefficient with the Barthel Index showed statistically significant values for all PEDI-I subscales (range 0.75-0.95).

CONCLUSION

The study provides evidence of good test-retest reliability and convergent validity when used in children with DS. Other psychometric proprieties need to be investigated in future studies.

Functional Skills among Preschool Children with Cerebral Palsy - Assessment before and after Early Intervention

Objective: To assess and evaluate the change in functional skills among children with cerebral palsy (CP) who participated in an intensified habilitation program. Methods: In this prospective longitudinal study, a cohort of 39 preschool children (2-5 years) with cerebral palsy (Gross Motor Function Classification System levels I-V) together with their parents participated in an intensified multidimensional habilitation program for 1 year. Activities strengthening functional skills were among the main interventions. The children were evaluated with the Pediatric Evaluation of Disability Inventory before and after the program period. Results: Only children at GMFCS levels I-II showed improvements in mobility and social function on norm-referenced scales. After the intervention period, these children scored similar to the mean for typically developing children of the same age on the social function domain. Conclusions: Functional skills among preschool children with CP, GMFCS levels I-II, seems strengthened after participation in an intensified habilitation program.

Validation of the Pediatric Evaluation of Disability Inventory in an Italian Population with Autism Spectrum Disorder: a Cross-Sectional Study

OBJECTIVES

To measure psychometric properties of the Italian version of the Pediatric Evaluation of Disability Inventory (PEDI-I) in a population with Autism Spectrum Disorder (ASD).

METHODS

The PEDI-I was administered to different children with ASD. The internal consistency was examined by using Cronbach's Alpha, while the intraclass correlation coefficient (ICC) was used to investigate both inter-observer and intra-observer reproducibility. Its concurrent validity was evaluated with the Italian version of the Barthel Index.

RESULTS

The PEDI-I was administered to 60 children with a diagnosis of ASD. Cronbach's Alpha showed statistically significant values (.885-.965). Inter-observer and intra-observer investigations confirm the reproducibility of the scale with a range of high and very high parameters. The Pearson Correlation Coefficient with the Barthel Index showed significant data for all PEDI-I subscales with a p<0.01.

CONCLUSIONS

The PEDI-I showed good psychometric properties and it is possible to confirm its validity and reliability in ASD population. However, for better understanding of how PEDI-I works in clinical practice, further researches are recommended.

Development and Validation of Equations to Link Pediatric Evaluation of Disability Inventory (PEDI) Functional Skills Scores to PEDI-Computer Adaptive Test Scores for Youth with Cerebral Palsy

Aim: The Pediatric Evaluation of Disability Inventory (PEDI) was revised to the PEDI-Computer Adaptive Test (PEDI-CAT). The PEDI has been used for over two decades to track function in youth, so it is important that follow-up data are not lost with this transition. The purpose of this study was to develop and validate equations for linking PEDI scores to PEDI-CAT scores.Methods: Caregivers of 101 youth 6.1 to 19.8 years of age with cerebral palsy (CP) and classified at Gross Motor Classification System (GMFCS) Levels I-V completed the PEDI and PEDI-CAT. Scaled score data from this sample were used to develop and validate linking equations using least squares regression and bootstrap cross-validation techniques. Next, equations were tested in an independent sample of 35 children with developmental disabilities.Results: The equations to predict PEDI-CAT scores exhibited excellent model fit. PEDI Self-care, Mobility, and Social Function explained 92%, 84%, and 85% of the variation in PEDI-CAT Daily Activities, Mobility, and Social/Cognitive domains, respectively. No differences were detected between actual and predicted PEDI-CAT scores across all domains and by GMFCS level for the equation development sample and for an equation validation independent sample.Conclusions: The model fit was excellent; however, equations should be used cautiously when evaluating changes in function for individual children with ceiling level PEDI scores. Valid score prediction equations for youth with CP will assist with transitioning from the PEDI to the PEDI-CAT.

Effect of Bisphosphonates on Function and Mobility Among Children With Osteogenesis Imperfecta: A Systematic Review

Osteogenesis imperfecta (OI) is a rare genetic connective tissue disorder that results in bone fragility and deformity. Management is multi-disciplinary. Although pharmacologic intervention with bisphosphonates (BP) is a standard of care for individuals with severe OI, no consensus or reviews were found that focus on the effects of bisphosphonates on function and mobility. PubMed, CINAHL, Cochrane Library, Web of Science, and PEDro databases were searched for eligible articles for this review. Methodological quality was assessed using the Cochrane Collaboration's tool for risk of bias. Twenty-six studies (801 children) were reviewed and five showed a low risk of bias. Included studies showed significant variability among clinical protocols for administering BP. Randomized controlled trials did not demonstrate a significant improvement in function and mobility with oral BP administration, while non-randomized open-label uncontrolled studies demonstrated that oral and intravenous BP administration objectively improved function and mobility. The most common outcome measure used by the studies included in this review was the Bleck score. Effect sizes (d = 0.28 - 4.5) varied among studies. This systematic review also summarized the apparent confounding variables affecting results of previous studies and provided suggestions to improve the quality of future studies.

The Uganda version of the Pediatric Evaluation of Disability Inventory (PEDI). Part I: Cross-cultural adaptation

BACKGROUND

The Pediatric Evaluation of Disability Inventory (PEDI) was developed and standardized to measure functional performance in American children. So far, no published study has examined the use of the PEDI in sub-Saharan Africa. This study describes the adaptation, translation, and validation process undertaken to develop a culturally relevant PEDI for Uganda (PEDI-UG).

METHOD

The cross-cultural adaptation and translation of the PEDI was performed in a series of steps. A project manager and a technical advisory group were involved in all steps of adaptation, translation, cognitive debriefing, and revision. Translation and back-translation between English and Luganda were performed by professional translators. Cognitive debriefing of two subsequent adapted revisions was performed by a field-testing team on a total of 75 caregivers of children aged 6 months to 7.5 years.

RESULTS

The PEDI-UG was established in both English (the official language) and Luganda (a local language) and comprises 185 items. Revisions entailed deleting irrelevant items, modifying wording, inserting new items, and incorporating local examples while retaining the meaning of the original PEDI. Item statements were rephrased as questions. Seven new items were inserted and 19 items deleted. To accommodate major differences in living conditions between rural and urban areas, 10 alternative items were provided.

CONCLUSIONS

The PEDI-UG is to be used to measure functional limitations in both clinical practice and research, in order to assess and evaluate rehabilitative procedures in children with developmental delay and disability in Uganda. In this study, we take the first step by translating and adapting the original PEDI version to the culture and life conditions in both rural and urban Uganda. In subsequent studies, the tool's psychometric properties will be examined, and the tool will be tested in children with developmental delay and disability.

The Ugandan version of the Pediatric Evaluation of Disability Inventory (PEDI-UG). Part II: Psychometric properties

BACKGROUND

The Pediatric Evaluation of Disability Inventory (PEDI) has been recommended as a gold standard in paediatric rehabilitation. A Ugandan version of PEDI (PEDI-UG) has been developed by culturally adapting and translating the original PEDI. The aim of this study was to investigate the psychometric properties of the PEDI-UG in Ugandan children by testing the instrument's rating scale functioning, internal structure, and test-retest reliability.

METHODS

Two hundred forty-nine Ugandan children (125 girls) aged 6 months to 7.5 years (Mean = 3.4, SD = 1.9) with typical development were tested using the PEDI-UG. Forty-nine children were tested twice to assess test-retest reliability. Validity was investigated by Rasch analysis and reliability by intraclass correlation coefficient.

RESULTS

The PEDI-UG domains showed good unidimensionality based on principal component analysis of residuals. Most activities (95%) showed acceptable fit to the Rasch model. Six misfit items were deleted from the Functional Skills scales and one from the Caregiver Assistance scales. The category steps on the Caregiver Assistance scales' rating scale were reversed but functioned well when changed from a 6-point to 4-point rating scale. The reliability was excellent; intraclass correlation coefficient was 0.87-0.92 for the domains of the Functional Skills scales and 0.86-0.88 for the domains of the Caregiver Assistance scales.

CONCLUSION

The PEDI-UG has good to excellent psychometric properties and provides a valid measure of the functional performance of typically developing children from the age of 6 months to 7.5 years in Uganda. Further analysis of all items, including misfit and deleted items, in children with functional disability is recommended.

Normative Scores for the Pediatric Evaluation of Disability Inventory in Norway

AIM

The aim of this study was to develop clinically useful normative scores for the Pediatric Evaluation of Disability Inventory (PEDI) for children in Norway, and provide information on the relative difficulty level of individual test items.

METHODS

Using PEDI protocols from 224 Norwegian children without disability, we computed and scrutinized the normative scores for their representativeness, and compared them with scores from 313 children in the original US PEDI sample. Item functioning was compared using Rasch model-based differential item functioning (DIF) analyses and comparisons of item mastery.

RESULTS

The normative scores yielded consistent and regular results. The mean scores for each age group in the Norwegian sample were lower than in their US counterparts, and age mean plots ran parallel. However, this difference may be misleading for clinical use, as item comparisons revealed differences in both higher and lower directions between the samples for about a third of all items. Estimates of relative item difficulty for children in Norway were developed.

CONCLUSIONS

Identifying potential differences when using an instrument in another culture is important to avoid a risk of over- or underestimating a child's capability. In addition, item response patterns are required to make national normative scores clinically useful.

Mothers' experiences with the Pediatric Evaluation of Disability Inventory (PEDI)

Parents of a child with a disability are often asked about their child's functioning in daily activities. One way to gather this information is through parent-report functional questionnaires such as the Pediatric Evaluation of Disability Inventory (PEDI). The purpose of this study was to explore parental experiences associated with completion of the PEDI before and after a functional therapy intervention. Semi-structured interviews were conducted with 12 mothers of children with cerebral palsy (CP) or developmental delay (DD) who had completed the PEDI within a larger study. A content analysis approach was used to code and organize the data into five themes. PEDI completion was associated with increased parental awareness of developmental patterns, and greater insight into levels of assistance they give to their child. Parents described various challenges and concerns with the PEDI that have implications for test administration processes. The findings have potential to enable more sensitive and focused PEDI use.

Functionality level and its relation to postural control during sitting-to-stand movement in children with cerebral palsy

In this study we studied functional performance and functional balance in children with cerebral palsy (CP) and typically developing (TD) children. The relationship between these components and postural control during sit-to-stand movement (STS) was also investigated. Ten children with CP (GMFCS I and II) and 27 TD children, ages 5-12 years, were included in the study. The Pediatric Evaluation of Disability Inventory (PEDI) and the Pediatric Balance Scale (PBS) were used to measure functional performance and functional balance, respectively. Postural control during STS was assessed by means of a force plate. Participants were asked to stand from a chair with feet over a force plate. Children with CP exhibited lower scores than TD children in the PBS and in the mobility Functional Skills and Caregiver Assistance domains of the PEDI (p≤0.05). In both groups postural control during STS movement was correlated with mobility Caregiver Assistance scores of the PEDI. The results demonstrate that although the participants had mild to moderate motor impairment, they exhibit deficits in their level of functional performance and functional balance compared to typical children. Moreover, it was observed that impairments in postural control during the STS movement are related to functional performance in both groups. This result demonstrates the importance of the structure and function components to the level of activity in children.
