Reliability and construct validity of the Activities Scale for Kids in Italian children with cerebral palsy

Effectiveness of action observation treatment based on pathological model in hemiplegic children: a randomized-controlled trial

BACKGROUND

Action observation treatment (AOT) is an innovative therapeutic approach consisting in the observation of actions followed by their subsequent repetition. The standard version of AOT consists in the observation/imitation of a typically developed individual, which is proposed as model (TDM-AOT).

AIM

This study aims to compare the effectiveness of AOT based on a pathological ameliorative model (PAM-AOT) versus TDM-AOT in improving upper limb ability in children with unilateral cerebral palsy (UCP).

DESIGN

The study consists in a prospective randomized controlled, evaluator-blinded trial (RCT), with two active arms, designed to evaluate the effectiveness of AOT based on pathological model (PAM-AOT) as compared to a standard AOT based on TDM (TDM-AOT).

SETTING

The 3-week AOT program was administered in a clinical setting. For some patients, the treatment was delivered at participant's home with the remote support of the physiotherapist (tele-rehabilitation).

POPULATION

Twenty-six children with UCP (mean age 10.5±3.09 years; 14 females) participated in the study, with the experimental group observing a pathological model and the control group observing a typically developed model.

METHODS

Motor assessments included unimanual and bimanual ability measures conducted at T0 (baseline, before the treatment), T1 (3 weeks after T0), T2 (8-12 weeks after treatment) and T3 (24-28 weeks after treatment); a subset of 16 patients also underwent fMRI motor assessment. Generalized Estimating Equations models were used for statistical analysis.

RESULTS

Both groups showed significant improvement in bimanual function (GEE, Wald 106.16; P<0.001) at T1 (P<0.001), T2 (P<0.001), and T3 (P<0.001). Noteworthy, the experimental group showed greater improvement than the control group immediately after treatment (P<0.013). Both groups exhibited similar improvement in unimanual ability (GEE, Wald 25.49; P<0.001). The fMRI assessments revealed increased activation of ventral premotor cortex after treatment in the experimental compared with control group (GEE, Wald 6.26; P<0.012).

CONCLUSIONS

Overall, this study highlights the effectiveness of PAM-AOT in achieving short-term improvement of upper limb ability in children with UCP.

CLINICAL REHABILITATION IMPACT

These findings have significant implications for rehabilitative interventions based on AOT in hemiplegic children, by proposing a non-traditional approach focused on the most functional improvement achievable by imitating a pathological model.

Participation Questionnaire for Preschoolers With Autism Spectrum Disorder: Item Development

Occupational therapists need to comprehensively assess the participation of children with autism spectrum disorder (ASD) in daily activities and evaluate the effectiveness of relevant interventions. Several participation measurement tools have been developed for children with ASD, but these tools require expert involvement, which is a barrier to large-scale surveys. To address these concerns, a caregiver-administered questionnaire-the Participation Questionnaire for Preschoolers (PQP)-was developed. However, this tool could be improved due to its narrow age range of 48-72 months and because the item development process does not reflect the perspectives of children and caregivers. Therefore, we expanded the PQP's target age range to 36-83 months and developed new items that reflect the perspectives of professionals and caregivers. Interviews were conducted with eight experts in supporting children with ASD and 11 caregivers of children with ASD. The interviews were transcribed, and a content analysis was performed. The number of questions was reduced from 51 to 36, and the order of items was changed for clarity. Two of the eight subdomains were removed to clarify the conceptual difference between activity and participation. The updated version of the PQP has two unique features: (1) it can be administered without expert involvement, and (2) it includes items specific to the challenges faced by children with ASD. Future development of the scale and validation of its measurement properties are needed.

Psychometric properties of the Spanish version of the Activities Scale for Kids (ASK): reliability, validity and the Rasch model

AIMS

To evaluate the psychometric properties of the Spanish version of the Activities Scale for Kids capability (ASKc) and ASK performance (ASKp) questionnaires.

DESIGN

It includes an analysis of different types of reliability (internal consistency, test-retest, inter-rater, Rasch model) and validity (convergent and discriminant) values.

SETTINGS

The sample was recruited in schools, associations and one hospital in Spain.

PARTICIPANTS

The main sample comprised 448 children (114 with disabilities); and 96 parents of the group of 114 children with disabilities, along with 2 therapists.

METHODS AND PROCEDURE

Children with physical disabilities completed questionnaires at two different time points; while healthy children only once. Both ASK questionnaires were also administered to parents. Therapists observed 69 children in 15 of the 30 activities listed in the ASKc.

PRIMARY AND SECONDARY OUTCOME MEASURES

ASKc and ASKp were used to measure physical disability among children. The Childhood Health Assessment Questionnaire (CHAQ), The Screening For and Promotion of Health-Related Quality of Life in Childrenand Adolescents - a European Public Health perspective (KIDSCREEN), Gross Motor Function Classification System (GMFCS), Manual Ability Classification System (MACS) and Functional Mobility Scale (FMS) were used to analyse convergent validity.

RESULTS

Excellent values were obtained for the reliability of the scale. Internal consistency was >0.95 (Cronbach's α) for both questionnaires. The intraclass correlation coefficient test-retest reliability was 0.94 (ASKc) and 0.93 (ASKp). Correlations between parents' and children's scores were 0.91(ASKc) and 0.90 (ASKp); and the correlation between therapists' and children's scores was 0.78. The Rasch analysis indicated that the Spanish version had a unidimensional structure. Furthermore, the results revealed adequate validity indices. Both ASK questionnaires correlated significantly with the CHAQ, three dimensions of the KIDSCREEN and the GMFCS, MACS and FMS. Finally, children without disabilities had higher ASKc and ASKp scores than children with disabilities (p=0.0001).

CONCLUSIONS

Both the ASKc and the ASKp versions are reliable and valid instruments that can be used to measure the capabilities of Spanish-speaking children, whose responses also demonstrate their own reliability as informants of the impact of disability on the activities of daily living.

Translation, cross-cultural adaptation, validity and reliability of the Brazilian Portuguese version of Activity Scale for Kids questionnaire

BACKGROUND

The Activity Scale for Kids (ASK) assesses the physical disability of children (5 to 15 years old) with neurological, orthopaedic or rheumatic diseases. The objective of this study was to translate and cross-culturally adapt the ASK for Brazilian Portuguese and assess the validity and reliability of the instrument.

METHODS

A total of 67 children and adolescents with musculoskeletal, neurological or rheumatic diseases participated in the study. We evaluated the comprehension of the pre-final version of the questionnaire in 24 participants and reliability and validity in the other 43 participants. The translation and adaptation of ASK to Brazilian Portuguese followed guidelines from previous studies. The validity of the Brazilian Portuguese version of the ASK was verified through Spearman's correlation with the Pediatric Quality of Life Inventory™ Version 4.0 (PedQL). Intraclass correlation coefficient verified inter- and intra-evaluator reliability, while internal consistency was assessed using Cronbach's alpha. Scores were used to assess the standard error of the mean and minimal detectable change.

RESULTS

The Brazilian Portuguese version of the ASK presented excellent reliability, internal consistency, agreement and moderate correlation with PedsQL (0.522, P < 0.001) between ASK performance and PedsQL; 0.537, P < 0.001 between ASK capacity and PedsQL.

CONCLUSION

The Brazilian Portuguese version of the ASK has good validity and reliability and may be used by professionals and researchers to assess the functioning of children and adolescents with disabilities.

Cognitive Orientation to Daily Occupational Performance (CO-OP) in Children with Cerebral Palsy: A Systematic Review with Meta-analysis

Background: Cognitive orientation to daily occupational performance (CO-OP) is a client-centered treatment approach that was developed in the 1990s by occupational therapists. Purpose: Exploring current evidence about the effectiveness of CO-OP on children with cerebral palsy (CP). Method: Major electronic databases were searched. A narrative synthesis of current literature and meta-analyses on randomized control trials (RCTs) were conducted on changes in occupational performance. Findings: Seven studies with 103 participants were included. Four studies were RCTs with moderate levels of evidence, and three studies had single-subject designs. Although beneficial effects of CO-OP on goal achievement and transferring learned skills were reported, meta-analyses showed that CO-OP had no significant effect on the performance (WMD = 1.52, 95% CI = -1.58 to 4.63, P = .33) and satisfaction domains (WMD = 1.71, 95% CI = -1.14 to 4.57, P = .24) of Canadian Occupational Performance Measure scores compared to alternative interventions. Implications: CO-OP improves occupational performance but not more than alternative interventions. Results are inconclusive due to small sample sizes and heterogeneity of alternative interventions and participants. Therefore, research with a larger number of participants with sound RCT methods is needed.

Can a pathological model improve the abilities of the paretic hand in hemiplegic children? The PAM-AOT study protocol of a randomised controlled trial

Introduction

Action Observation Treatment (AOT) is an innovative therapeutic approach consisting in the observation of actions followed by subsequent repetition. In children with unilateral cerebral palsy (UCP), it improves upper limb function in daily activities. The standard paradigm of AOT requires the observation of healthy models; however, it has been demonstrated that the mirror neuron system of children with UCP is more activated by observation of pathological models, showing a similar motor repertoire, than by the healthy model, suggesting that AOT based on pathological models is superior to the standard paradigm of AOT in the functional rehabilitation of the affected upper limb of children with UCP.

Methods and analysis

This protocol describes an active two-arm randomised controlled evaluator-blinded trial. Twenty-six children with UCP will participate in 3 weeks of intensive AOT: the experimental group will observe a pathological model, while the control group will observe a typically developed model. The primary outcome is the spontaneous use of the paretic hand, measured with the Assisting Hand Assessment. Secondary outcome measures are the Melbourne Assessment of Unilateral Upper Limb Function, the ABILHAND-Kids and the Activities Scale for Kids-performance. Assessments will be performed at baseline (T0), at the end of intensive AOT (T1), at 8–12 weeks (T2) and at 24–28 weeks (T3) after the end of intensive AOT.

Ethics and dissemination

The trial was approved by the Area Vasta Emilia Nord Ethics Committee (AVEN prot. n. 133117, 29 November 2018), and it was prospectively registered on ClinicalTrials.gov. The results will be submitted for publication to a peer-reviewed journal, discussed with parents of children participating in the trial and disseminated at suitable conferences.
