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.     

The Relationship Between Manual Ability and Ambulation in Adolescents with Cerebral Palsy

ABSTRACT

This study examined the relationship between gross motor function and manual ability in 120 adolescents with cerebral palsy (CP) (15.2, SD 2.1 years, 59.8% male). Adolescents were evaluated using the Gross Motor Function Classification System (GMFCS) and the Manual Ability Classification System (MACS). A neurologist classified CP subtype. Most adolescents were ambulatory with or without utilization of aids (GMFCS level I: 35.0%, II: 30.0%, III: 5.8%, IV: 10.8%, and V: 18.3%). MACS levels were I: 34.2%, II: 25.8%, III: 16.7%, IV: 7.5%, and V: 15.8%. Correlations between GMFCS and MACS were strong in youth with quadriplegia (r = .89, p < .001), moderate in individuals with diplegia (r = .58, p = .01), but weakly associated for adolescents with hemiplegia (r = .24, p = .23). The findings provide evidence for maintaining a clinical distinction between spastic quadriplegia and spastic diplegia. Manual ability may not be congruent with mobility in adolescents with CP and should be specifically evaluated given its importance to daily life functioning.     

Longitudinal Changes in Physical Caregiving for Parents of Children with Cerebral Palsy

Abstract

Aims: To determine changes in physical caregiving for parents of children with cerebral palsy (CP) over a two-year period based on children’s gross motor function level and age.

Methods: 153 parents of children with CP rated their physical caregiving using the Ease of Caregiving for Children three times over two years. Parents and assessors classified children’s gross motor function using the Gross Motor Function Classification System (GMFCS). Physical caregiving was compared at three test times among parents of children grouped by GMFCS level (I, II–III, and IV–V) and age (1.7–5.9 and 6–11?years) using a three-way mixed ANOVA.

Results: Among all analyses, a two-way interaction was found between children’s GMFCS level and test time on ease of caregiving, p?<?0.01. Change over two-year period was found for parents of children in level I and II–III, p?<?0.01, but not parents of children in levels IV–V. At each test time, parents of children in level I reported the greatest ease of caregiving followed by parents of children in levels II–III, and levels IV–V, who reported the lowest ease of caregiving, p?<?0.001.

Conclusions: Findings support evaluation and monitoring of physical caregiving for parents of children with CP over time.     

Concurrent Validity of the School Outcomes Measure (SOM) and Pediatric Evaluation of Disability Inventory (PEDI) in Preschool-Age Children

ABSTRACT

Aims: The purpose of this study was to examine the concurrent validity of the School Outcomes Measure (SOM) compared with the Pediatric Evaluation of Disability Inventory (PEDI) in preschool-age children. This study also examined the consistency of children's motor performance across the home and school settings. Methods: Five school-based physical therapists collected data on 44 preschool-age children with physical or combined physical and cognitive disability. Correlation coefficients analyzed the strength of association between SOM and PEDI subscale scores, while participant group mean scores analyzed agreement between measures regarding level of motor performance. Results: Correlations between homologous PEDI and SOM subscale scores varied from r_s = .53 to r_s = .92 supporting concurrent validity. With some exceptions, group mean SOM scores showed agreement with group mean PEDI scores when children were categorized by age, gross motor function level, or PEDI cutoff score (1 or 2 SD below the mean). Conclusions: The results partially support concurrent validity between the SOM and PEDI, and suggest that the children's motor performance was similar across home and school settings. The findings also suggest that as a minimal database the SOM can reliably assess motor performance in the school setting; the disadvantage is difficulty interpreting SOM scores.     

Psychosocial adjustment in a Dutch sample of children with cerebral palsy

BackgroundOver the last couple of years, there has been increasing interest for QoL in children with CP. Psychosocial adjustment in these children remains underrepresented in current literature.AimsTo describe psychosocial adjustment in children with CP by means of the Psychosocial Adjustment and Role Skills Scale III (PARS-III), to describe the psychometric properties of this questionnaire, to identify a cut-off score for psychosocial maladjustment and to investigate the relationship between patient characteristics (i.e. predictive factors) and psychosocial adjustment.MethodsThe parents of 93 children with CP (59 boys, 34 girls; mean age 12.3 years, SD 3.8; 4–18; GMFCS 1: 28, GMFCS 2: 5, GMFCS 3: 19, GMFCS 4: 18, GMFCS 5: 23) completed the PARS-III and the Child Behavior Checklist (CBCL) concerning the psychosocial and behavioral functioning of their child.ResultsCronbach’s alpha-coefficient for the PARS-III was 0.89 indicating good internal consistency. High correlation with the CBCL was found. Confirmatory factor analysis confirmed the 6 domain structure of the PARS-III. Overall, children with CP achieved lower psychosocial adjustment scores compared to healthy children. A cut-off score (1 SD below the mean) of 78 was found. When predicting psychosocial maladjustment in children with CP, less gross motor function, hand function, communication skills and bilateral involvement of CP are the most important factors, but these can only explain 36% of variation in psychosocial adjustment.ConclusionUsing the by-proxy version of the PARS-III it was found that children with CP are reported to achieve lower psychosocial adjustment scores than healthy children.     

Reliability of the Functional Mobility Scale for Children with Cerebral Palsy

ABSTRACT

This study examined inter-rater reliability of the Functional Mobility Scale (FMS) for children with cerebral palsy (CP) and the presence of rater bias. A consecutive sample of 118 children with CP, 2–18 years old (mean 10.3 years, SD 3.6), was recruited from a hospital setting. Children were classified using the gross motor function classification system (GMFCS) with 13 in Level I, 49 in Level II, 44 in Level III, and 12 in Level IV. Each child was independently scored on the FMS by two raters. Raters were randomly assigned from a sample of 44 orthopaedic surgeons, hospital-based physiotherapists, and community-based physiotherapists. Quadratic weighted kappa coefficients for mobility ratings varied from 0.86 to 0.92 for the three distances, indicating substantial chance corrected agreement. Levels of agreement were similar when administering the scale in person and by telephone, suggesting that the FMS can be administered by either method. There was a tendency for surgeons to rate mobility higher than physiotherapists, however, only one of the comparisons was statistically significant. The FMS is a reliable tool that can be used by clinicians to assess mobility in children with CP.     

Self-Care Trajectories and Reference Percentiles for Children with Cerebral Palsy

Abstract

Aims: To create longitudinal trajectories and reference percentiles for performance in self-care of children with cerebral palsy (CP).

Methods: Participants were 708 children with CP, 18?months through 11 years of age and their parents residing in 10 regions across Canada and the United States. Gross Motor Function Classification System (GMFCS) levels were determined by consensus between parents and therapists. Parents’ completed the Performance in Self-Care domain of the Child Engagement in Daily Life Measure two to five times at 6-month intervals. Nonlinear mixed-effects models were used to create longitudinal trajectories. Quantile regression was used to construct cross-sectional reference percentiles.

Results: The trajectories for children in levels I, II, and III are characterized by an average maximum score between 79.6 (level I) and 62.8 (level III) and an average attainment of 90% of the maximum score between 7 and 9?years of age. The trajectories for children in level IV and V show minimal change over time. Extreme variation in performance among children of the same age and GMFCS level complicate interpretation of percentile change of individual children.

Conclusion: The findings are useful for monitoring self-care of children with CP and evaluating change for children in GMFCS levels I–III.     

A New Approach to the Measurement of Adaptive Behavior: Development of the PEDI-CAT for Children and Youth with Autism Spectrum Disorders

ABSTRACT. The use of current adaptive behavior measures in practice and research is limited by their length and need for a professional interviewer. There is a need for alternative measures that more efficiently assess adaptive behavior in children and youth with autism spectrum disorders (ASDs). The Pediatric Evaluation of Disability Inventory-Computer Adaptive Test (PEDI-CAT) is a computer-based assessment of a child's ability to perform activities required for personal self-sufficiency and engagement in the community. This study evaluated the applicability, representativeness, and comprehensiveness of the Daily Activity, Social/Cognitive, and Responsibility domains for children and youth with an ASD. Twenty professionals and 18 parents provided feedback via in-person or virtual focus groups and cognitive interviews. Items were perceived to represent relevant functional activities within each domain. Child factors and assessment characteristics influenced parents’ ratings. In response to feedback, 15 items and additional directions were added to ensure the PEDI-CAT is a meaningful measure when used with this population.     

How Does the Functional Mobility Scale Relate to Capacity-Based Measures of Walking Ability in Children and Youth with Cerebral Palsy?

ABSTRACT

This study examined the relationship between walking performance rated on the Functional Mobility Scale (FMS) and measures of walking capacity in children with cerebral palsy (CP). A total of 143 participants with spastic CP (GMFCS levels I to III) were rated on the FMS and had assessment of self-selected walking speed (WS), fast 1 minute walk test (1MWT) and six minute walk test (6MWT). For each FMS distance, children rated 6 had significantly better 6MWT than children scored 5; children rated FMS 2, 3, or 4 had lower walking capacity measures but were not clearly distinguishable from each other. The 6MWT was an independent predictor of variation in FMS score, accounting for 20% to 27% of the variance across the three FMS distances. While walking capacity impacts on community mobility in children with CP much of the variance remains unexplained, suggesting that other factors play an important role.     

Discriminative Validity of the Danish Version of the Pediatric Evaluation of Disability Inventory (PEDI)

ABSTRACT

The Pediatric Evaluation of Disability Inventory (PEDI) assesses functional status in children with disabilities aged 0.5–7.5 years. The purpose of this study was to examine if the Danish version of the PEDI was able to discriminate between nondisabled children and children with cerebral palsy (CP) or juvenile idiopathic arthritis (JIA). Convenience sampling was used to select the clinical samples that consisted of 22 children with CP and 14 children with JIA aged 1.5–7.5 years. An additional sample, consisting of 224 nondisabled children aged 1.0–5.9 years, was obtained on the basis of random sampling. The PEDI was administered as a questionnaire completed by the parents. Results from receiver operating characteristics (ROC) analysis showed that in the case of discrimination between children with CP and nondisabled children, the sensitivity and specificity were 77.3 and 97.8%, respectively. In the discrimination between children with JIA and nondisabled children, the sensitivity and specificity were 99.8 and 81.7%, respectively. Study results indicate that the Danish version of the PEDI shows good discriminative validity. Further studies of the discriminative validity are recommended.     

Effect of Group-Task-Oriented Training on Gross and Fine Motor Function,and Activities of Daily Living in Children with Spastic Cerebral Palsy

Abstract

Aims: To determine the effects of group-task-oriented training (group-TOT) on gross and fine motor function, activities of daily living (ADL) and social function of children with spastic cerebral palsy (CP).

Methods: Eighteen children with spastic CP (4–7.5?years, gross motor function classification system level I–III) were randomly assigned to the Group-TOT (9 children received group-TOT for 1?hour, twice a week for 8?weeks) or the comparison group (9 children received individualized traditional physical and occupational therapy). The Gross Motor Function Measure (GMFM)-88, the Bruininks-Oseretsky Test of Motor Proficiency 2^nd edition (BOT-2), and the Pediatric Evaluation of Disability Inventory (PEDI) were administered before and after the intervention, and in the Group-TOT, 16?weeks after the intervention.

Results: Children in the Group-TOT showed significant improvements in the GMFM-88 standing and walking/running/jumping subscales, the BOT-2 manual dexterity subscale, and the PEDI social function subscale (p?<?0.05); changes were maintained 16?weeks after the intervention ended. In contrast, the comparison group improved in only the BOT-2 fine motor integration subscale (p?<?0.05).

Conclusions: The findings provide evidence of effectiveness of group-TOT in improving gross and fine motor function, and social function in children with CP.     

Reliable Classification of Functional Profiles and Movement Disorders of Children with Cerebral Palsy

ABSTRACT

Objective: To examine the inter-rater reliability of the Communication Function Classification System (CFCS), Bimanual Fine Motor Function (BFMF), Surveillance of Cerebral Palsy in Europe (SCPE) classification tree, and Gross Motor Function Classification System (GMFCS) in children with cerebral palsy (CP) and periventricular white matter injury (PWMI) aged 4–11 years. Method: Twenty children were assessed by two raters using the four tools, in addition parents undertook ratings on the Manual Ability Classification System (MACS). Kappa statistics were used to calculate the level of agreement between raters’ classifications. Results: Participants comprised 12 males and 8 females with CP and PWMI, mean age 8 years 1 month (standard deviation 2 years 3 months). Inter-rater reliability across the four tools was 0.98 (CFCS, BFMF, and GMFCS) and 0.84 (SCPE). Implications: These findings suggest that these four tools are reasonably robust to inter-rater variability supporting their routine use along with the MACS in clinical and research applications.

Item Bank Development for a Revised Pediatric Evaluation of Disability Inventory (PEDI)

ABSTRACT

The Pediatric Evaluation of Disability Inventory (PEDI) is a useful clinical and research assessment, but it has limitations in content, age range, and efficiency. The purpose of this article is to describe the development of the item bank for a new computer adaptive testing version of the PEDI (PEDI-CAT). An expanded item set and response options were reviewed by clinician experts and examined at parent and clinician focus groups. Eleven parents participated in 32 cognitive interviews to examine content, format, and comprehension of items and responses. A set of 76 self-care, 78 mobility, and 64 social function items with pictures and a four-point “Difficulty” scale were developed. The PEDI's Caregiver Assistance scale was replaced by a “Responsibility Scale” with 53 items. Content validity was established incorporating input from clinicians and parents. The new item bank covers a broad range of functional activities for children of all ages and abilities.     

Therapeutic Effects of Horseback Riding Therapy on Gross Motor Function in Children with Cerebral Palsy: A Systematic Review

ABSTRACT

Purpose: This systematic review examined the efficacy of hippotherapy or therapeutic horseback riding (THR) on motor outcomes in children with cerebral palsy (CP). Methods: Databases were searched for clinical trials of hippotherapy or THR for children with CP. Results: Nine articles were included in this review. Although the current level of evidence is weak, our synthesis found that children with spastic CP, Gross Motor Function Classification System (GMFCS) levels I–III, aged 4 years and above are likely to have significant improvements on gross motor function as a result of hippotherapy and THR. Evidence indicates that 45-min sessions, once weekly for 8–10 weeks, result in significant effects. Conclusions: The current literature on hippotherapy and THR is limited. Large randomized controlled trials using specified protocols are needed to more conclusively determine the effects on children with CP. From the current evidence, it appears that hippotherapy and THR have positive effects on gross motor function in children with CP.     

Change in Parent-Identified Goals in Young Children with Cerebral Palsy Receiving a Context-Focused Intervention: Associations with Child,Goal and Intervention Factors

ABSTRACT

The purpose of this study was to examine the relationship between goal achievement measured by the Canadian Occupational Performance Measure (COPM) and child, goal, and intervention factors. Participants were 41 preschool children with cerebral palsy (CP) who were in the context-focused therapy arm of a randomized controlled trial. Factors including child age, Gross Motor Function Classification System (GMFCS) level, type and complexity of goals, and intervention strategies were analyzed. Children made large, positive mean changes on the COPM over 6 months (Performance = 3.8, SD = 1.9; Satisfaction = 4.3, SD 4.3) with younger children showing greater change. The COPM scores had low to moderate correlations with change on the Pediatric Evaluation of Disability Inventory and the Gross Motor Function Measure (GMFM-66). Regression analysis indicated that age, but not GMFCS level influenced COPM change scores. Goal complexity and intervention strategies were not significantly related to COPM change scores. The results provide support for using the COPM as an individualized measure of change in young children with CP receiving intervention.     

Higher Levels of Caregiver Strain Perceived by Indian Mothers of Children and Young Adults with Cerebral Palsy Who have Limited Self-Mobility

Aim: Describe and compare the caregiver strain experienced among Indian mothers of children and young adults with cerebral palsy (CP) living in low resource settings. Methods: 62 consecutive children and young adults with spastic CP (mean age 6.0 ± 4.5, range 2–21) and their parents were recruited from an outpatient physiotherapy department for this cross-sectional study. Ability to walk was classified using the Gross Motor Function Classification System and mother's caregiver strain was measured using caregiver strain index (CSI). Results: Mothers of children and young adults who have limited self-mobility perceived higher caregiver strain (mean CSI score 12.0 ± 1.3, p < 0.05) than mothers of children who can walk (mean CSI score 4.5 ± 3.0, p < 0.05). All 46 mothers of children and youth in GMFCS levels IV and V reported high levels of caregiver stress compared with only three of 16 mothers of children and youth who walk (levels I and II). Conclusions: Physiotherapists and occupational therapists serving children and youth with CP are encouraged to partner with families to identify goals for ease of caregiving, activity, and participation at home and in the community.     

The Effects of a 5-Day Virtual-Reality Based Exercise Program on Kinematics and Postural Muscle Activity in Youth with Cerebral Palsy

Aims: To determine the effects of a 5-day virtual reality (VR)-based intervention on anticipatory and reactive mechanisms of postural control in children and adolescents with cerebral palsy (CP). Methods: Eleven youth with CP (GMFCS levels I and II), ages 7–17, were allocated to intervention (N?=?5) and control (N?=?6) groups. Both groups attended balance assessment sessions 1?week apart. Participants in the intervention group received 1-hour one-on-one physiotherapist-supervised VR balance games for 5 consecutive days between assessments. For balance assessments, participants stood erect with eyes open on a movable platform that translated progressively through four speeds in the anterior/posterior direction. Participants performed two trials each of experimenter-triggered and self-triggered perturbations. Postural muscle activity and kinematics were recorded. The Anchoring Index and body segment cross-correlations were calculated as an indication of body stabilization, and the number of steps taken to regain balance/avoid falling were counted. Mann–Whitney U tests for between group differences in change scores were undertaken with an accepted significance level of 0.01. Results: No consistent differences in change scores were identified between groups. Conclusions: There was no effect of a 5-day VR-based intervention on postural control mechanisms used in response to oscillating platform perturbations. Subsequent studies will further tailor VR interventions to patients’ functional balance needs.
