The application of virtual reality to home-based rehabilitation for children and adolescents with cerebral palsy: A systematic review and meta-analysis

BACKGROUND

Home-based rehabilitation enables children and families to participate in therapeutic activities built into their daily routines without the barriers of arrangement and transportation to facilities. Virtual reality is an emerging technology which has shown promising outcomes in rehabilitation.

PURPOSE

This systematic review aims to examine the feasibility and effects of virtual reality-enhanced home rehabilitation on Body functions and structures, Activity, and Participation outcomes in children and adolescents with cerebral palsy.

METHODS

Interventional studies were searched across five biomedical databases on November 26, 2022. Two independent reviewers conducted study selection, data extraction, and quality assessment. The Physiotherapy Evidence Database scale and National Institutes of Health Study Quality Assessment Tools were used to evaluate the quality of included studies. Meta-analysis was performed to examine the effects of the intervention.

RESULTS

Eighteen studies were included in this review. Home-based virtual reality rehabilitation appears feasible with effects on upper extremity and gross motor function, strength, bone density, cognition, balance, walking, daily activity performance, and participation. Meta-analyses revealed significant improvements in hand function (SMD = 0.41, p= .003), gross motor function (SMD = 0.56, p= .0002), and walking capacity (SMD = 0.44, p= .01) following home-based virtual reality intervention.

CONCLUSION

Home-based virtual reality may serve as an adjunct to conventional facility-based therapy to promote participation in therapeutic exercises and maximize rehabilitation outcomes. Further properly designed randomized controlled trials using valid and reliable outcome measures with adequately powered sample sizes are warranted to enhance the current body of evidence using home-based virtual reality in cerebral palsy rehabilitation.

The wide world of technological telerehabilitation for pediatric neurologic and neurodevelopmental disorders - a systematic review

Introduction

The use of Information and Communication Technology (ICT) for assessing and treating cognitive and motor disorders is promoting home-based telerehabilitation. This approach involves ongoing monitoring within a motivating context to help patients generalize their skills. It can also reduce healthcare costs and geographic barriers by minimizing hospitalization. This systematic review focuses on investigating key aspects of telerehabilitation protocols for children with neurodevelopmental or neurological disorders, including technology used, outcomes, caregiver involvement, and dosage, to guide clinical practice and future research.

Method

This systematic review adhered to PRISMA guidelines and was registered in PROSPERO. The PICO framework was followed to define the search strategy for technology-based telerehabilitation interventions targeting the pediatric population (aged 0-18) with neurological or neurodevelopmental disorders. The search encompassed Medline/PubMed, EMBASE, and Web of Science databases. Independent reviewers were responsible for selecting relevant papers and extracting data, while data harmonization and analysis were conducted centrally.

Results

A heterogeneous and evolving situation emerged from our data. Our findings reported that most of the technologies adopted for telerehabilitation are commercial devices; however, research prototypes and clinical software were also employed with a high potential for personalization and treatment efficacy. The efficacy of these protocols on health or health-related domains was also explored by categorizing the outcome measures according to the International Classification of Functioning, Disability, and Health (ICF). Most studies targeted motor and neuropsychological functions, while only a minority of papers explored language or multi-domain protocols. Finally, although caregivers were rarely the direct target of intervention, their role was diffusely highlighted as a critical element of the home-based rehabilitation setting.

Discussion

This systematic review offers insights into the integration of technological devices into telerehabilitation programs for pediatric neurologic and neurodevelopmental disorders. It highlights factors contributing to the effectiveness of these interventions and suggests the need for further development, particularly in creating dynamic and multi-domain rehabilitation protocols. Additionally, it emphasizes the importance of promoting home-based and family-centered care, which could involve caregivers more actively in the treatment, potentially leading to improved clinical outcomes for children with neurological or neurodevelopmental conditions.

Effectiveness of Virtual Reality for Upper Extremity Function and Motor Performance of Children With Cerebral Palsy: A Systematic Review

IMPORTANCE

Research on the functional and motor performance impact of virtual reality (VR) as an intervention tool for children with cerebral palsy (CP) is limited.

OBJECTIVE

To understand whether VR is an effective intervention to improve upper extremity (UE) function and motor performance of children diagnosed with CP.

DATA SOURCES

Databases used in the search were EBSCOhost, One Search, PubMed, Cloud Source, CINAHL, SPORTDiscus, and Google Scholar.

STUDY SELECTION AND DATA COLLECTION

Studies published from 2006 to 2021 were included if children had a diagnosis of CP and were age 21 yr or younger, VR was used as an intervention, and measures of UE function and motor performance were used.

FINDINGS

Twenty-one studies were included, and the results provided promising evidence for improvements in areas of UE function, motor performance, and fine motor skills when VR is used as an intervention. To yield noticeable UE improvements in children with CP, VR should be implemented for 30 to 60 min/session and for at least 360 min over more than 3 wk. Additional areas of improvement include gross motor skills, functional mobility, occupational performance, and intrinsic factors.

CONCLUSIONS AND RELEVANCE

The use of VR as an intervention for children with CP to improve UE function and motor performance is supported. More randomized controlled trials with larger sample sizes focusing on similar outcomes and intervention frequencies are needed to determine the most effective type of VR for use in clinical occupational therapy. Plain-Language Summary: This systematic review explains how virtual reality (VR) has been used as an intervention with children with cerebral palsy (CP). The review synthesizes the results of 21 research studies of children who had a diagnosis of CP and who were 21 years old or younger. The findings support using VR to improve upper extremity performance, motor performance, and fine motor skills. The findings also show that occupational therapy practitioners should use a VR intervention at a minimum frequency of 30 to 60 minutes per session and for at least 360 minutes over more than 3 weeks to yield noticeable improvements in upper extremity, motor performance, and fine motor skills for children with CP.

Reporting Completeness of Intensity-, Dose-, and Dosage-Related Items in Active Pediatric Upper Limb Neurorehabilitation Trials: A Systematic Review

OBJECTIVE

To analyze the reporting completeness of the TIDieR items 8-12, in particular intensity, dose, and dosage, in active pediatric upper limb neurorehabilitation trials.

DATA SOURCES

We searched PubMed Central, Scopus, CINAHL, OTseeker, and Web of Science for eligible publications.

STUDY SELECTION

We included publications analyzing active pediatric upper limb neurorehabilitation interventions and assessed the reporting completeness of 11 items for each intervention and control group.

DATA EXTRACTION

Two raters independently screened titles and abstracts and selected the publications using the RYYAN platform. We unblinded the results after the raters had completed their selection and resolved the disagreements by discussion. We used the same procedures to review the full texts.

DATA SYNTHESIS

We included 52 randomized controlled trials with 65 intervention and 48 control groups. Authors did not report all 11 items in any of the study groups. The overall reporting completeness varied between 1% (intensity) to 95% (length of the intervention). The reporting completeness of the TIDieR items ranged from 2% (modifications) to 64% (when and how much). We found no significant differences in the reporting completeness between the intervention and control groups.

CONCLUSIONS

Information essential for dose-response calculations is often missing in randomized controlled trials of pediatric upper limb neurorehabilitation interventions. Reporting completeness should be improved, and new measures to accurately quantify intensity should be discussed and developed.

Application of Virtual Reality-Assisted Exergaming on the Rehabilitation of Children with Cerebral Palsy: A Systematic Review and Meta-Analysis

BACKGROUND

Rehabilitation programs for children with cerebral palsy (CP) aim to improve their motor and cognitive skills through repeated and progressively challenging exercises. However, these exercises can be tedious and demotivating, which can affect the effectiveness and feasibility of the programs. To overcome this problem, virtual reality VR-assisted exergaming has emerged as a novel modality of physiotherapy that combines fun and motivation with physical activity. VR exergaming allows children with CP to perform complex movements in a secure and immersive environment, where they can interact with virtual objects and scenarios. This enhances their active engagement and learning, as well as their self-confidence and enjoyment. We aim to provide a comprehensive overview of the current state of research on VR exergaming for CP rehabilitation. The specific objectives are: To identify and describe the existing studies that have investigated the effects of VR exergaming on motor function and participation outcomes in children with CP. In addition, we aim to identify and discuss the main gaps, challenges, and limitations in the current research on VR exergaming for CP rehabilitation. Finally, we aim to provide recommendations and suggestions for future research and practice in this field.

METHODS

In June 2023, we conducted a systematic search on Scopus, Web of Science, PubMed, Cochrane, and Embase for randomized trials and cohort studies that applied VR-assisted exergaming to rehabilitating patients with CP. The inclusion criteria encompassed the following: (1) Randomized controlled trials (RCTs) and cohort studies involving the rehabilitation of children with CP; (2) the application of VR-based exergaming on the rehabilitation; (3) in comparison with conventional rehabilitation/usual care. The quality of the selected RCTs was evaluated using Cochrane's tool for risk of bias assessment bias includes. Whereas the quality of cohort studies was assessed using the National Institutes of Health (NIH) tool.

RESULTS

The systematic search of databases retrieved a total of 2576 studies. After removing 863 duplicates, 1713 studies underwent title and abstract screening, and 68 studies were then selected as eligible for full-text screening. Finally, 45 studies were involved in this review (n = 1580), and 24 of those were included in the quantitative analysis. The majority of the included RCTs had a low risk of bias regarding study reporting, participants' attrition, and generating a random sequence. Nearly half of the RCTs ensured good blinding of outcomes assessors. However, almost all the RCTs were unclear regarding the blinding of the participants and the study personnel. The 2020 retrospective cohort study conducted at Samsung Changwon Hospital, investigating the effects of virtual reality-based rehabilitation on upper extremity function in children with cerebral palsy, demonstrated fair quality in its methodology and findings. VR-assisted exergaming was more effective than conventional physiotherapy in improving the Gross Motor Function Measurement (GMFM)-88 score (MD = 0.81; 95% CI [0.15, 1.47], p-value = 0.02) and the GMFM walking and standing dimensions (MD = 1.45; 95% CI [0.48, 2.24], p-value = 0.003 and MD = 3.15; 95% CI [0.87, 5.42], p-value = 0.007), respectively. The mobility and cognitive domains of the Pediatric Evaluation of Disability Inventory score (MD = 1.32; 95% CI [1.11, 1.52], p-value < 0.001) and (MD = 0.81; 95% CI [0.50, 1.13], p-value < 0.0001) were also improved. The Canadian Occupational Performance Measure performance domain (MD = 1.30; 95% CI [1.04, 1.56], p-value < 0.001), the WeeFunctional Independence Measure total score (MD = 6.67; 95% CI [6.36, 6.99], p-value < 0.0001), and the Melbourne Assessment of Unilateral Upper Limb Function-2 score (p-value < 0.001) improved as well. This new intervention is similarly beneficial as conventional therapy in improving other efficacy measures.

CONCLUSIONS

Our findings suggest that VR-assisted exergaming may have some advantages over conventional rehabilitation in improving CP children's functioning and performance in daily life activities, upper and lower limb mobility, and cognition. VR-assisted exergaming seems to be as effective as conventional physiotherapy in the other studied function measures. With its potential efficacy, better feasibility, no reported side effects, and entertaining experience, VR-assisted exergaming may be a viable complementary approach to conventional physiotherapy in rehabilitating children with CP.

Short- to Long-Term Effects of Virtual Reality on Motor Skill Learning in Children With Cerebral Palsy: Systematic Review and Meta-Analysis

BACKGROUND

Many studies have started integrating virtual reality (VR) into neurorehabilitation for children with cerebral palsy (CP). The results of the effects of VR on motor skill learning, including the short- to long-term results of relevant studies, must be pooled in a generic framework.

OBJECTIVE

This systematic review and meta-analysis aimed to investigate the short- to long-term effects of therapies including VR on motor skill learning in children with CP.

METHODS

Two examiners followed the inclusion and exclusion criteria of the "Participant, Intervention, Control, and Outcome" framework. Randomized controlled trials (RCTs) and non-RCTs were considered if they compared VR-included interventions with control groups on motor functions and daily life activities in children with CP. PubMed, ScienceDirect, Embase, and IEEE Xplore databases were searched. The modified Downs and Black assessment was used to assess the methodological quality of the included studies. Meta-analyses and subgroup analyses for RCTs were conducted whenever possible.

RESULTS

A total of 7 RCTs, 2 non-RCTs, and 258 children with CP were included. The priority focus of 78% (7/9) of the studies was upper limb functions. There was a significant short-term effect of adding VR to conventional therapies on upper limb functions when compared with conventional therapies (P=.04; standardized mean difference [SMD]=0.39, 95% CI 0.01-0.76). The overall medium- to long-term effects showed a trend toward favoring the VR group, although the difference was not statistically significant (P=.06; SMD=0.37, 95% CI -0.02 to 0.77). For balance (P=.06; SMD=1.04, 95% CI -0.04 to 2.12), gross motor functions (P=.30; SMD=2.85, 95% CI -2.57 to 8.28), and daily life activities outcomes (P=.21; SMD=0.29, 95% CI -0.16 to 0.74), the overall effect in the short term also showed a trend toward favoring the VR group, but these results were not statistically significant.

CONCLUSIONS

VR seems to have additional benefits for motor skill learning in children with CP. Studies with follow-up outcomes of VR training focusing on balance and gross motor functions in patients with CP were quite limited. Future research on balance and gross motor function outcomes should target particularly long-term results of therapies including VR on motor skill learning.

Effectiveness and Users' Perceptions of Upper Extremity Exoskeletons and Robot-Assisted Devices in Children with Physical Disabilities: Systematic Review

AIM

Systematically determine the effectiveness and users' perceptions of upper extremity (UE) exoskeletons and robot-assisted devices for pediatric rehabilitation.

METHODS

PubMed/Medline, Web of Science, Scopus, and Cochrane Library were searched for studies with "exoskeletons"/"robot-assisted devices", children with disabilities, effectiveness data, and English publication. Intervention effectiveness outcomes were classified within components of the International Classification of Functioning, Disability, and Health, Children and Youth Version (ICF-CY). Secondary data (users' perceptions; implementation setting) were extracted. Risk of bias and methodological quality were assessed. Descriptive analyses were performed.

RESULTS

Seventy-two articles were included. Most evaluated body structure and function and activity outcomes with less emphasis on participation. Most effects across all ICF-CY levels were positive. Devices were primarily evaluated in clinical or laboratory rather than natural environments. Perceptions about device effectiveness were mostly positive, while those about expression, accessibility, and esthetics were mostly negative. A need for increased rigor in research study design was detected.

CONCLUSIONS

Across populations, devices, settings, interventions, and dosing schedules, UE exoskeletons and robot-assisted devices may improve function, activity, and perhaps participation for children with physical disabilities. Future work should transition devices into natural environments, design devices and implementation strategies to address users' negative perceptions, and increase research rigor.

The Use of Serious Gaming to Improve Sensorimotor Function and Motivation in People with Cerebral Palsy: A Systematic Review

The aim of this systematic review was to review the evidence for serious gaming interventions in improving sensorimotor function in children and adults with cerebral palsy (CP). Seven databases were searched with terms related to serious gaming and CP. Articles were evaluated according to the Downs and Black rating scale and important principles of serious gaming defined by Whyte et al. Extracted data included the population, intervention, serious gaming elements, outcomes, and authors' conclusions. Fifty-seven articles were identified for inclusion. Participants' ages ranged from 3 to 57 years. Interventions tested included commercial videogames as well as specially designed games. Most interventions had themed content, short-term goals, rewards, feedback, and multiple games. Outcome measures and study designs were inconsistent between studies. Sensorimotor function results of noncomparative studies were positive or neutral overall, but results of comparative studies were more mixed. We concluded that serious gaming interventions may be a useful adjunct to treatment as they are noninvasive, were not associated with deterioration in most cases, and may improve compliance. More comparative studies need to be completed to assess compliance and treatment outcomes. Future games should also aim to adhere more closely to the principles of serious gaming.

A protocol for a single-arm interventional study assessing the effects of a home-based joystick-operated ride-on-toy navigation training programme to improve affected upper extremity function and spontaneous use in children with unilateral cerebral palsy (UCP)

INTRODUCTION

Children with unilateral cerebral palsy (UCP) face significant limitations in upper extremity (UE) function and require effective interventions that promote intensive goal-directed practice while maximising motivation and adherence with therapy. This study builds on our past work and will assess the effects of a 6-week researcher-caregiver codelivered, home-based ride-on-toy navigation training (RNT) programme in young children with UCP. We hypothesise that the RNT programme will be acceptable, feasible to implement, and lead to greater improvements in unimanual and bimanual function when combined with conventional therapy, compared with conventional therapy provided alone.

METHODS AND ANALYSIS

15 children with UCP between 3 and 8 years will be recruited. During the 6-week control phase, participants will receive treatement-as-usual alone. During the subsequent 6-week intervention phase, in addition to conventional therapy, RNT will be provided 4-5 times/week (2 times by researchers, 2-3 times by caregivers), 30-45 min/session. We will assess UE function using standardised tests (Quality of Upper Extremity Skills Test and Shriner's Hospital Upper Extremity Evaluation), reaching kinematics, wrist-worn accelerometry, caregiver-rated ABILHAND-Kids questionnaire, and training-specific measures of movement control during RNT. Programme feasibility and acceptance will be assessed using device use metrics, child and caregiver exit questionnaires, training-specific measures of child engagement, and the Physical Activity Enjoyment Scale. All assessments will be conducted at pretest, following the control phase (midpoint), and after completion of the intervention phase (post-test).

ETHICS AND DISSEMINATION

The study is approved by the Institutional Review Board of the University of Connecticut (# H22-0059). Results from this study will be disseminated through peer-reviewed manuscripts in scientific journals in the field, through national and international conferences, and through presentations to parent advocacy groups and other support organisations associated with CP.

Can wrist-worn devices and a smartphone application influence arm activity in children with unilateral cerebral palsy? A proof-of-concept study

Aim

To determine whether a wrist-worn triaxial accelerometer-based device and software (including smartphone application), incorporating feedback, is feasible, acceptable, and can lead to increased affected upper limb use during everyday activities in children with unilateral cerebral palsy (UCP).

Methods

Study design: Mixed methods proof of concept study. Participants: Children aged 8-18 years with UCP; age-matched typically developing controls ("Buddies"), therapists. Intervention: Baseline (2 weeks): devices recorded arm activity. Active feedback (6 weeks): devices also gave vibratory prompts if affected arm activity fell below pre-set personalised thresholds (UCP group only; control group continued as per Baseline). Final 2 weeks: as baseline. Both groups accessed a smartphone application providing feedback on relative arm motion throughout the study. Assessment and analysis: ABILHAND-Kids questionnaires and MACS classifications captured baseline participant characteristics (UCP group). Accelerometer data was used to calculate relative arm activity (signal vector magnitude) corrected for time worn/day, and trends in relative arm activity examined using single case experimental design (both groups). In-depth interviews with families, "Buddies" and therapists assessed feasibility and acceptability of implementation. A framework approach was used for qualitative data analysis.

Results

We recruited 19 participants with UCP; 19 buddies; and 7 therapists. Five participants (two with UCP) did not complete the study. Baseline mean (stdev) ABILHAND-Kids score of children with UCP who completed the study was 65.7 (16.2); modal MACS score was II.Qualitative analysis demonstrated acceptability and feasibility of the approach. Active therapist input for this group was minimal. Therapists appreciated the potential for summary patient data to inform management. Arm activity in children with UCP increased in the hour following a prompt (mean effect size z = 0.261) for the non-dominant hand, and the dominant hand (z = 0.247). However, a significant increase in affected arm activity between baseline and intervention periods was not demonstrated.

Discussion

Children with UCP were prepared to wear the wristband devices for prolonged periods. Whilst arm activity increased bilaterally in the hour following a prompt, increases were not sustained. Delivery of the study during the COVID-19 pandemic may have negatively influenced findings. Technological challenges occurred but could be overcome. Future testing should incorporate structured therapy input.

Do randomised controlled trials evaluating functional outcomes following botulinum neurotoxin-A align with focal spasticity guidelines? A systematic review

PURPOSE

The impact of botulinum neurotoxin-A (BoNT-A) on functional outcomes when managing focal muscle spasticity remains unclear. It is possible that randomised controlled trial (RCT) design and/or reporting may be a contributing factor. The objective of this review was to determine the extent to which RCTs evaluating functional outcomes following BoNT-A align with focal spasticity guidelines.

MATERIALS AND METHODS

RCTs published from 2010 were included if they targeted focal spasticity, included BoNT-A, randomised a physical intervention to the upper/lower limb, or the primary outcome(s) related to the activity/participation domains of the International Classification of Functioning, Disability, and Health. Data extraction and quality appraisal using the Modified PEDro and Modified McMasters Tool were performed independently by two reviewers. General research practices were also extracted such as compliance with therapy reporting guidelines.

RESULTS

Fifty-two RCTs were eligible. Individualised goal setting was uncommon (25%). Six studies (11.5%) included multi-disciplinary management, and five (9.6%) included patient/caregiver education. Four studies (7.7%) measured outcomes beyond 6 months. The Median Modified PEDro score was 11/15.

CONCLUSIONS

Alignment with focal spasticity guidelines in RCTs was generally low. Our understanding of the impact of focal spasticity management on functional outcomes may be improved if RCT design aligned more closely with guideline recommendations.IMPLICATIONS FOR REHABILITATIONThe influence of BoNT-A on improved functional outcomes is yet to be determined.Individualised goal setting with a multi-disciplinary team is uncommon in an RCT design, despite it being a key guideline recommendation.Given the long-term nature of spasticity management, guidelines recommend short as well as long-term reviews following intervention however RCTs rarely assess beyond 6 months.

[Feedback strategies in assistive technology to promote social participation in children with cerebral palsy: Systematic review]

INTRODUCTION

Living with cerebral palsy has consequences such as social interaction. Assistive technologies used for improving independence only focuses on biological and physiological variables. The main objective in this review is to synthesize the evidence on interventions with assistive technologies, including feedback systems, with the aim of discovering outcomes of social participation in children with cerebral palsy.

METHODOLOGY

There were 5 databases from rehabilitation which showed 683 articles in which only 9 were included.

RESULTS

The studies assessed social participation with several instruments. The majority suggested positive effects in activities such as: walking, writing, playing, and social interaction. There were tools such as electronic pencils, switches, and exoskeletons present.

CONCLUSION

Due to the poor quality of the methodologies of these studies, the search does not establish solid conclusions. However, the evidence suggests that assistive technologies with feedback have a positive impact on aspects of social participation.

Telehealth and remote interventions for children with cerebral palsy: A scoping review

Background

Remote treatment, or telehealth, has shown promise for children with cerebral palsy (CP) prior to 2020; however, the beginning of the global COVID-19 pandemic limiting access to hospitals for face-to-face treatments has driven the need for telehealth and led to a surge in its development. Due to the recent developments, there has been limited synthesis of the available evidence of telehealth for children with CP.

Objective

This study aimed to analyze and summarize the existing evidence for telehealth interventions for the treatment of children with CP and identify any areas requiring further research.

Methods

A scoping review was performed. A systematic search of available literature in MEDLINE and PubMed was performed during July 2021. Inclusion criteria for articles were primary research and systematic reviews that investigated telehealth, included children with CP, were published between 2010-2021, and were written in English. Exclusion criteria were secondary research other than systematic reviews; interventions that did not meet the World Health Organization definition of telehealth; or studies where all participants were aged >18 years, children’s results were not reported separately, or there were no results reported for children with CP. A scoping review was chosen due to the expected heterogeneity of the participants, as well as the expected small sample sizes and inconsistency of measured outcomes; therefore, a narrative reporting of the results was considered appropriate.

Results

In all, 5 papers were identified, which included the results of 11 studies—2 of the included articles were systematic reviews, which included the results of 3 studies each. These 6 studies, together with 5 primary research articles, were included in this scoping review. The existing evidence is of low methodological quality, primarily consisting of case series. There is some evidence that the requirements of telehealth differ depending on the children’s developmental stage and functional level. Telehealth is reported to reduce caregiver burden. There is mixed evidence on children’s compliance with telehealth. Overall, the results of telehealth interventions for the treatment of children with CP were positive, indicating either comparable or improved results compared with children receiving usual face-to-face care.

Conclusions

The evidence base is lacking in breadth and methodological quality to provide robust clinical recommendations. Most studies investigated hand function only, indicating the limited scope of existing research. However, this review shows that telehealth has demonstrated potential to improve function for children with CP while making health care services more accessible and reducing caregiver burden. Areas requiring further research include telehealth interventions for the lower limb, postural management, and pain control and the barriers to implementing telehealth.

Effectiveness of virtual reality in children and young adults with cerebral palsy: a systematic review of randomized controlled trial

BACKGROUND

Cerebral palsy (CP) is one of the main causes of disability in childhood. Virtual reality (VR) has been used as a treatment option in this population, however its effectiveness is unclear.

OBJECTIVE

To evaluate the effectiveness of VR in patients with CP.

METHODS

We conducted electronic searches in EMBASE, MEDLINE, Cochrane library, PEDro, AMED, PsycoINFO, and LILACS databases and trial site registries such as ClinicalTrials.gov and ICTRP. We included randomized controlled trials that tested the use of VR alone or in combination with other interventions compared to more conventional rehabilitation or usual care in individuals with CP. The primary outcomes were upper and lower limb function, postural control, and balance. The secondary outcomes included global motor function, perception, cognition and spatial functions, motivation, motor learning, and adverse events. Two independent reviewers extracted and assessed included articles for risk of bias using the Cochrane risk of bias tool. We use a meta-analysis with random effect model whenever possible. We analyzed the quality of evidence using theGRADE approach.

RESULTS

We included 38 trials (pooled n = 1233 participants) in this review. There is very low quality of evidence that VR plus conventional rehabilitation is better than conventional rehabilitation for upper limb function. There is also very low quality evidence that VR alone is no better than conventional rehabilitation for upper and lower limb function. No adverse events were observed among the 10 trials that provided information on this outcome.

CONCLUSION

At present we have very limited to limited confidence in effect estimation for utilization of VR in this population. Future studies may change our confidence in results and effect estimates.

Immersive Virtual Environments and Wearable Haptic Devices in rehabilitation of children with neuromotor impairments: a single-blind randomized controlled crossover pilot study

Background

The past decade has seen the emergence of rehabilitation treatments using virtual reality. One of the advantages in using this technology is the potential to create positive motivation, by means of engaging environments and tasks shaped in the form of serious games. The aim of this study is to determine the efficacy of immersive Virtual Environments and weaRable hAptic devices (VERA) for rehabilitation of upper limb in children with Cerebral Palsy (CP) and Developmental Dyspraxia (DD).

Methods

A two period cross-over design was adopted for determining the differences between the proposed therapy and a conventional treatment. Eight children were randomized into two groups: one group received the VERA treatment in the first period and the manual therapy in the second period, and viceversa for the other group. Children were assessed at the beginning and the end of each period through both the Nine Hole Peg Test (9-HPT, primary outcome) and Kinesiological Measurements obtained during the performing of similar tasks in a real setting scenario (secondary outcomes).

Results

All subjects, not depending from which group they come from, significantly improved in both the performance of the 9-HPT and in the parameters of the kinesiological measurements (movement error and smoothness). No statistically significant differences have been found between the two groups.

Conclusions

These findings suggest that immersive VE and wearable haptic devices is a viable alternative to conventional therapy for improving upper extremity function in children with neuromotor impairments.

Feasibility and effectiveness of home-based therapy programmes for children with cerebral palsy: a systematic review

OBJECTIVE

To assess the feasibility and effectiveness of home-based occupational therapy and physiotherapy programmes in children with cerebral palsy (CP), focusing on the upper extremity and reporting on child-related and/or parent-related outcomes.

DESIGN

Systematic review.

DATA SOURCES

Electronic searches were performed in MEDLINE, EMBASE, CINAHL, PsycINFO, OTseeker and PEDro, and in ICTRP and CENTRAL trial registers, from inception to 6 June 2019.

ELIGIBLE CRITERIA

The review included all types of original studies concerning feasibility or effectiveness of home-based therapy in children aged <18 years with any type of CP. No language, publication status or publication date restrictions were applied.

DATA EXTRACTION AND SYNTHESIS

Study and intervention characteristics and the demographics of participating children and their parents were extracted. Feasibility was assessed by outcomes related to acceptability, demand, implementation, practicality, adaptation, expansion or integration. Regarding effectiveness, child-related outcome measures related to any level of the International Classification of Functioning, Disability and Health, or parent-related outcomes were investigated. Two authors independently extracted the data. Risk of bias was assessed using the Downs and Black checklist and the Joanna Briggs Institute Critical Appraisal Checklist.

RESULTS

The search resulted in a total of 92 records: 61 studies and 31 conference abstracts. Feasibility studies reported mainly on acceptability and implementation. Overall compliance to home-based training programmes (implementation) was moderate to high, ranging from 56% to 99%. In the effectiveness studies, >40 different child-related outcome measures were found. Overall, an improvement in arm-hand performance within group across time was shown. Only two studies reported on a parent-related outcome measure. No increase in parental stress was found during the intervention.

CONCLUSIONS

Based on the results of the included studies, home-based training programmes seem to be feasible. However, conclusions about the effectiveness of home programmes cannot be made due to the large variability in the study, patient and intervention characteristics, comparators, and outcome measures used in the included studies.

Documenting change with the Canadian Occupational Performance Measure for children with cerebral palsy

AIM

To assess the Canadian Occupational Performance Measure's (COPM) ability to document change over 3 years in children with cerebral palsy (CP).

METHOD

This was a prospective study with ambulatory children with CP, aged 2 to 6 years. Caregivers set one to three COPM goals which were rescored annually over 3 years. A ceiling effect for performance goals was operationalized as a score of 8. A Wald χ² generalized estimating equations model adjusted for age, sex, and Gross Motor Function Classification System (GMFCS) level, evaluated change over time.

RESULTS

In total, 124 children (47 [37.9%] females, 77 [62.1%] males; mean age 3y 11mo [SD 1y 1mo]; GMFCS level I [n=78, 62.9%], II [n=21, 16.9%], and III [n=25, 20.2%]) were set 345 COPM goals at baseline. By Year 3, 106 participants (85.5%) rescored 287 of the goals (83.2%). Performance scores increased between baseline mean (SD) 2.93 (0.56), Year 1 5.98 (0.58) with 34.8% at ceiling; Year 2 6.74 (0.60) 48.3% at ceiling; and Year 3 7.37 (0.60) 59.6% at ceiling (Wald χ² [3]=607.18, p<0.001). Satisfaction scores increased between baseline 4.42 (0.59), Year 1 6.82 (0.60) with 48% at ceiling; Year 2 7.53 (0.60) with 62.2% at ceiling (Wald χ² [3]=208.48, p<0.001); with no significant increase by Year 3 7.82 (0.62) with 66.9% at ceiling.

INTERPRETATION

COPM performance scores increased steadily over 3 years. By Year 2, a ceiling effect was seen in about half of the goals. The COPM may have utility to measure change over 3 years; periodic resetting of the descriptors of goal success are required to minimize ceiling.

A Serious Game on the First-Aid Procedure in Choking Scenarios: Design and Evaluation Study

Background

Choking is one of the causes of unintentional injury death. Gaining the knowledge of the first-aid procedure that has to be applied in case of choking can increase the chances of survival of persons with choking. Serious games can be a good channel for educating people about choking scenarios and the actions to be taken to save the persons with choking.

Objective

The objective of this study is to present and evaluate the effectiveness of a serious game designed to prevent choking and to promote the first-aid procedure that needs to be applied in case of choking.

Methods

In this study, we present a serious game as a set of minigames that reproduces the main steps of the protocol for the first-aid performed in choking. In the proposed game, the player acquires the role of a helper who has to save the person in a choking emergency by applying the main steps of the protocol. Time and score restrictions are imposed to pass each minigame. To test this game, we performed a pilot study with 48 high school students. Different tests were performed to assess the students’ preferences and their knowledge on choking before and after playing the proposed game. The obtained results were analyzed using Mann-Whitney U test when a grade variable was involved and by using Fisher exact test when 2 categorical variables were involved.

Results

The findings of our study showed that the players enjoyed the game. No statistical differences were detected when considering the gender of the player, their preferences for video games, or their previous experience in choking emergencies. By comparing the knowledge of these students before and after playing the game, we found that all the indicators of the knowledge about how to act in case of a choking emergency were improved through this serious game.

Conclusions

The findings of our study show that the proposed game is a good strategy for promoting and teaching first-aid procedures in choking emergencies to nonexperts in this field.

Digital Behavior Change Interventions for Younger Children With Chronic Health Conditions: Systematic Review

Background

The prevalence of chronic health conditions in childhood is increasing, and behavioral interventions can support the management of these conditions. Compared with face-to-face treatment, the use of digital interventions may be more cost-effective, appealing, and accessible, but there has been inadequate attention to their use with younger populations (children aged 5-12 years).

Objective

This systematic review aims to (1) identify effective digital interventions, (2) report the characteristics of promising interventions, and (3) describe the user’s experience of the digital intervention.

Methods

A total of 4 databases were searched (Excerpta Medica Database [EMBASE], PsycINFO, Medical Literature Analysis and Retrieval System Online [MEDLINE], and the Cochrane Library) between January 2014 and January 2019. The inclusion criteria for studies were as follows: (1) children aged between 5 and 12 years, (2) interventions for behavior change, (3) randomized controlled trials, (4) digital interventions, and (5) chronic health conditions. Two researchers independently double reviewed papers to assess eligibility, extract data, and assess quality.

Results

Searches run in the databases identified 2643 papers. We identified 17 eligible interventions. The most promising interventions (having a beneficial effect and low risk of bias) were 3 targeting overweight or obesity, using exergaming or social media, and 2 for anxiety, using web-based cognitive behavioral therapy (CBT). Characteristics of promising interventions included gaming features, therapist support, and parental involvement. Most were purely behavioral interventions (rather than CBT or third wave), typically using the behavior change techniques (BCTs) feedback and monitoring, shaping knowledge, repetition and substitution, and reward. Three papers included qualitative data on the user’s experience. We developed the following themes: parental involvement, connection with a health professional is important for engagement, technological affordances and barriers, and child-centered design.

Conclusions

Of the 17 eligible interventions, digital interventions for anxiety and overweight or obesity had the greatest promise. Using qualitative methods during digital intervention development and evaluation may lead to more meaningful, usable, feasible, and engaging interventions, especially for this underresearched younger population. The following characteristics could be considered when developing digital interventions for younger children: involvement of parents, gaming features, additional therapist support, behavioral (rather than cognitive) approaches, and particular BCTs (feedback and monitoring, shaping knowledge, repetition and substitution, and reward). This review suggests a model for improving the conceptualization and reporting of behavioral interventions involving children and parents.

The Effect of a Rehabilitation Specific Gaming Software Platform to Achieve Individual Physiotherapy Goals in Children with Severe Spastic Cerebral Palsy: A Randomized Crossover Trial

Cerebral palsy (CP) is the most common cause of permanent neurological disabilities in children. Many children require long-term daily physiotherapy (PT), and videogaming is a promising tool to increase motivation in rehabilitation. The short- and medium-term effects of an intervention with rehabilitation specific videogames were evaluated on individually defined therapy goals, gross motor function, and motivation. Thirty-two children with bilateral spastic CP, Gross Motor Function Classification level III-IV, and 6-15 years were randomized into an intervention group (regular PT and gaming) or a control group (regular PT), followed by a crossover. The effects of both training periods (each 12 weeks) were compared using the Goal Attainment Scale (GAS), Trunk Control Measurement Scale (TCMS), Pediatric Balance Scale (PBS), Gross Motor Function Measure-88 (GMFM-88), and Dimensions of Mastery Motivation Questionnaire (DMQ). After 3 months follow-up, children were retested using the GMFM, TCMS, and PBS. The GAS change scores were significantly higher after the intervention compared to the control period (8.5 and 2.4, P < 0.001). The change scores for standing exercises (3.85 and 0.22, P = 0.04) and dynamic sitting balance (5.9 and -1.7, P < 0.001) were also significantly higher. After 3 months follow-up the results did not persist. A combined approach of regular PT and rehabilitation specific gaming showed significant effects on individually defined therapy goals, dynamic sitting balance, and standing exercises. However, the lack of persistent effect indicates that continuous individual goal-oriented PT with the addition of gaming is needed.

Engaging children with cerebral palsy in interactive computer play-based motor therapies: theoretical perspectives

PURPOSE

To provide a theoretically grounded understanding of engagement in interactive computer play-based motor therapies by children with cerebral palsy in home settings.

METHODS

A motivational framework for engagement and its relationship with three contemporary theories (self-determination theory, expectancy-value theory, social cognitive theory of self-regulation) was overviewed. A scoping review was conducted to understand how engagement is influenced by features of the technology and intervention design that impact intrinsic and extrinsic motivation, child and parent values and expectancies, and the processes of self-regulation. Multiple reviewers screened and extracted data from 26 articles describing home-based clinical trials of interactive computer play-based motor interventions for children with cerebral palsy. A narrative synthesis framework was used for analysis.

RESULTS

Features of the technology and the intervention influence feelings of autonomy (e.g., personalization), competence (e.g., calibration), and relatedness (e.g., social play, virtual therapist/coach). There may be multiple and differently valued goals in interactive computer play-based interventions (e.g., game- and therapy-focused) that, if disconnected or unmet, negatively impact engagement. Multiplayer interactions, real-time feedback and progress tracking provide information that influences self-regulation and engagement over time.

CONCLUSIONS

Optimizing engagement in interactive computer play-based motor interventions requires closer alignment with client-led values/goals; design of technologies and interventions that sustain intrinsic motivation; and feedback that informs/builds self-efficacy. Implications for rehabilitation The decision to prescribe an interactive computer play-based motor intervention should be guided by client-led goals and an informed understanding of the capacity of the interactive computer play-based intervention to meet individual client values/expectancies. Sustaining intrinsic motivation in interactive computer play-based motor therapies is greatly influenced by features of the technology (e.g., calibration, feedback, personalization) and the intervention (e.g., interactions with therapists, social play). Increased effort should be directed towards ensuring that interactive computer play-based interventions and technologies reward and reinforce efforts towards therapy goals.

Games Used With Serious Purposes: A Systematic Review of Interventions in Patients With Cerebral Palsy

The purpose of the present systematic review was to examine extant research regarding the role of games used seriously in interventions with individuals with cerebral palsy. Therefore, PubMed, PsyINFO, Web of Science, Scopus, and IEEE databases were used. Search terms included: “serious games” OR “online games” OR “video games” OR “videogame” OR “game based” OR “game” AND “intervention” AND “cerebral palsy.” After the full reading and quality assessment of the papers, 16 studies met the inclusion criteria. The majority of the studies reported high levels of compliance, motivation, and engagement with game-based interventions both at home and at the clinical setting intervention. Regarding the effectiveness of the use of games, the results of the studies show both positive and negative results regarding their effectiveness. The efficacy was reported to motor function (i.e., improvements in the arm function, hand coordination, functional mobility, balance and gait function, postural control, upper-limbs function) and physical activity. Findings of this review suggest that games are used as a complement to conventional therapies and not as a substitute. Practitioners often struggle to get their patients to complete the assigned homework tasks, as patients display low motivation to engage in prescribed exercises. Data of this review indicates the use of games as tools suited to promote patients’ engagement in the therapy and potentiate therapeutic gains.

Serious Games for Children with Chronic Diseases: A Systematic Review

OBJECTIVE

The purpose of this study was to systematically review the literature to assess if serious games impact health outcomes for children less than 18 years of age with chronic diseases. Additionally, the impact of self-efficacy, adherence, knowledge, use of theory, parent involvement, and study quality was also examined.

MATERIALS AND METHODS

Searches were conducted in databases EBSCO, PubMed, and Web of Science between June and August 2016. Randomized controlled trials using a serious game as an intervention, for participants under 18 years of age, to improve their chronic disease were included.

RESULTS

Data were extracted by two independent researchers, including: Title, author, and publication year; chronic disease; game description; number and age of participants; intervention duration; significant findings; parent involvement; theory; and study quality. Any disagreements were tackled and consensus was achieved. Eighteen studies were included in the review. The areas of health addressed included cerebral palsy, asthma, diabetes, developmental coordination disorders, and vision disorders. In these articles, eight health outcome variables were measured, including: lung function, glycemic control, hospital visits, motor proficiency, and visual acuity. Psychosocial variables that were assessed included self-efficacy and knowledge. Two articles included parents in the intervention, and three articles used theory. Six studies had significant health outcome finding, and four studies found a significant change in one psychosocial variable.

CONCLUSION

This review demonstrates the potential for games to improve health outcomes of young individuals. However, the mixed results suggest that more serious game interventions need to be better designed and rigorously tested to support their impact on improving health outcomes.

Effectiveness of Virtual Reality in Children With Cerebral Palsy: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

BACKGROUND

Researchers recently investigated the effectiveness of virtual reality (VR) in helping children with cerebral palsy (CP) to improve motor function. A systematic review of randomized controlled trials (RCTs) using a meta-analytic method to examine the effectiveness of VR in children with CP was thus needed.

PURPOSE

The purpose of this study was to update the current evidence about VR by systematically examining the research literature.

DATA SOURCES

A systematic literature search of PubMed, CINAHL, Cochrane Central Register of Controlled Trials, ERIC, PsycINFO, and Web of Science up to December 2016 was conducted.

STUDY SELECTION

Studies with an RCT design, children with CP, comparisons of VR with other interventions, and movement-related outcomes were included.

DATA EXTRACTION

A template was created to systematically code the demographic, methodological, and miscellaneous variables of each RCT. The Physiotherapy Evidence Database (PEDro) scale was used to evaluate the study quality. Effect size was computed and combined using meta-analysis software. Moderator analyses were also used to explain the heterogeneity of the effect sizes in all RCTs.

DATA SYNTHESIS

. The literature search yielded 19 RCT studies with fair to good methodological quality. Overall, VR provided a large effect size (d = 0.861) when compared with other interventions. A large effect of VR on arm function (d = 0.835) and postural control (d = 1.003) and a medium effect on ambulation (d = 0.755) were also found. Only the VR type affected the overall VR effect: an engineer-built system was more effective than a commercial system.

LIMITATIONS

The RCTs included in this study were of fair to good quality, had a high level of heterogeneity and small sample sizes, and used various intervention protocols.

CONCLUSIONS

Then compared with other interventions, VR seems to be an effective intervention for improving motor function in children with CP.

Virtual Reality and Serious Games in Neurorehabilitation of Children and Adults: Prevention, Plasticity, and Participation

Use of virtual reality (VR) and serious games (SGs) interventions within rehabilitation as motivating tools for task specific training for individuals with neurological conditions are fast-developing. Within this perspective paper we use the framework of the IV STEP conference to summarize the literature on VR and SG for children and adults by three topics: Prevention; Outcomes: Body-Function-Structure, Activity and Participation; and Plasticity. Overall the literature in this area offers support for use of VR and SGs to improve body functions and to some extent activity domain outcomes. Critical analysis of clients' goals and selective evaluation of VR and SGs are necessary to appropriately take advantage of these tools within intervention. Further research on prevention, participation, and plasticity is warranted. We offer suggestions for bridging the gap between research and practice integrating VR and SGs into physical therapist education and practice.

Exercise interventions for cerebral palsy

BACKGROUND

Cerebral palsy (CP) is a neurodevelopmental disorder resulting from an injury to the developing brain. It is the most common form of childhood disability with prevalence rates of between 1.5 and 3.8 per 1000 births reported worldwide. The primary impairments associated with CP include reduced muscle strength and reduced cardiorespiratory fitness, resulting in difficulties performing activities such as dressing, walking and negotiating stairs.Exercise is defined as a planned, structured and repetitive activity that aims to improve fitness, and it is a commonly used intervention for people with CP. Aerobic and resistance training may improve activity (i.e. the ability to execute a task) and participation (i.e. involvement in a life situation) through their impact on the primary impairments of CP. However, to date, there has been no comprehensive review of exercise interventions for people with CP.

OBJECTIVES

To assess the effects of exercise interventions in people with CP, primarily in terms of activity, participation and quality of life. Secondary outcomes assessed body functions and body structures. Comparators of interest were no treatment, usual care or an alternative type of exercise intervention.

SEARCH METHODS

In June 2016 we searched CENTRAL, MEDLINE, Embase, nine other databases and four trials registers.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) and quasi-RCTs of children, adolescents and adults with CP. We included studies of aerobic exercise, resistance training, and 'mixed training' (a combination of at least two of aerobic exercise, resistance training and anaerobic training).

DATA COLLECTION AND ANALYSIS

Two review authors independently screened titles, abstracts and potentially relevant full-text reports for eligibility; extracted all relevant data and conducted 'Risk of bias' and GRADE assessments.

MAIN RESULTS

We included 29 trials (926 participants); 27 included children and adolescents up to the age of 19 years, three included adolescents and young adults (10 to 22 years), and one included adults over 20 years. Males constituted 53% of the sample. Five trials were conducted in the USA; four in Australia; two in Egypt, Korea, Saudi Arabia, Taiwan, the Netherlands, and the UK; three in Greece; and one apiece in India, Italy, Norway, and South Africa.Twenty-six trials included people with spastic CP only; three trials included children and adolescents with spastic and other types of CP. Twenty-one trials included people who were able to walk with or without assistive devices, four trials also included people who used wheeled mobility devices in most settings, and one trial included people who used wheeled mobility devices only. Three trials did not report the functional ability of participants. Only two trials reported participants' manual ability. Eight studies compared aerobic exercise to usual care, while 15 compared resistance training and 4 compared mixed training to usual care or no treatment. Two trials compared aerobic exercise to resistance training. We judged all trials to be at high risk of bias overall.We found low-quality evidence that aerobic exercise improves gross motor function in the short term (standardised mean difference (SMD) 0.53, 95% confidence interval (CI) 0.02 to 1.04, N = 65, 3 studies) and intermediate term (mean difference (MD) 12.96%, 95% CI 0.52% to 25.40%, N = 12, 1 study). Aerobic exercise does not improve gait speed in the short term (MD 0.09 m/s, 95% CI -0.11 m/s to 0.28 m/s, N = 82, 4 studies, very low-quality evidence) or intermediate term (MD -0.17 m/s, 95% CI -0.59 m/s to 0.24 m/s, N = 12, 1 study, low-quality evidence). No trial assessed participation or quality of life following aerobic exercise.We found low-quality evidence that resistance training does not improve gross motor function (SMD 0.12, 95% CI -0.19 to 0.43, N = 164, 7 studies), gait speed (MD 0.03 m/s, 95% CI -0.02 m/s to 0.07 m/s, N = 185, 8 studies), participation (SMD 0.34, 95% CI -0.01 to 0.70, N = 127, 2 studies) or parent-reported quality of life (MD 12.70, 95% CI -5.63 to 31.03, n = 12, 1 study) in the short term. There is also low-quality evidence that resistance training does not improve gait speed (MD -0.03 m/s, 95% CI -0.17 m/s to 0.11 m/s, N = 84, 3 studies), gross motor function (SMD 0.13, 95% CI -0.30 to 0.55, N = 85, 3 studies) or participation (MD 0.37, 95% CI -6.61 to 7.35, N = 36, 1 study) in the intermediate term.We found low-quality evidence that mixed training does not improve gross motor function (SMD 0.02, 95% CI -0.29 to 0.33, N = 163, 4 studies) or gait speed (MD 0.10 m/s, -0.07 m/s to 0.27 m/s, N = 58, 1 study) but does improve participation (MD 0.40, 95% CI 0.13 to 0.67, N = 65, 1 study) in the short-term.There is no difference between resistance training and aerobic exercise in terms of the effect on gross motor function in the short term (SMD 0.02, 95% CI -0.50 to 0.55, N = 56, 2 studies, low-quality evidence).Thirteen trials did not report adverse events, seven reported no adverse events, and nine reported non-serious adverse events.

AUTHORS' CONCLUSIONS

The quality of evidence for all conclusions is low to very low. As included trials have small sample sizes, heterogeneity may be underestimated, resulting in considerable uncertainty relating to effect estimates. For children with CP, there is evidence that aerobic exercise may result in a small improvement in gross motor function, though it does not improve gait speed. There is evidence that resistance training does not improve gait speed, gross motor function, participation or quality of life among children with CP.Based on the evidence available, exercise appears to be safe for people with CP; only 55% of trials, however, reported adverse events or stated that they monitored adverse events. There is a need for large, high-quality, well-reported RCTs that assess the effectiveness of exercise in terms of activity and participation, before drawing any firm conclusions on the effectiveness of exercise for people with CP. Research is also required to determine if current exercise guidelines for the general population are effective and feasible for people with CP.

Development of a parent-reported questionnaire evaluating upper limb activity limitation in children with cerebral palsy

BACKGROUND AND PURPOSE

Upper limb activity measures for children with cerebral palsy have a number of limitations, for example, lack of validity and poor responsiveness. To overcome these limitations, we developed the Children's Arm Rehabilitation Measure (ChARM), a parent-reported questionnaire validated for children with cerebral palsy aged 5-16 years. This paper describes both the development of the ChARM items and response categories and its psychometric testing and further refinement using the Rasch measurement model.

METHODS

To generate valid items for the ChARM, we collected goals of therapy specifically developed by therapists, children with cerebral palsy, and their parents for improving activity limitation of the upper limb. The activities, which were the focus of these goals, formed the basis for the items. Therapists typically break an activity into natural stages for the purpose of improving activity performance, and these natural orders of achievement formed each item's response options. Items underwent face validity testing with health care professionals, parents of children with cerebral palsy, academics, and lay persons. A Rasch analysis was performed on ChARM questionnaires completed by the parents of 170 children with cerebral palsy from 12 hospital paediatric services. The ChARM was amended, and the procedure repeated on 148 ChARMs (from children's mean age: 10 years and 1 month; range: 4 years and 8 months to 16 years and 11 months; 85 males; Manual Ability Classification System Levels I = 9, II = 26, III = 48, IV = 45, and V = 18).

RESULTS

The final 19-item unidimensional questionnaire displayed fit to the Rasch model (chi-square p = .18), excellent reliability (person separation index = 0.95, α = 0.95), and no floor or ceiling effects. Items showed no response bias for gender, distribution of impairment, age, or learning disability.

DISCUSSION

The ChARM is a psychometrically sound measure of upper limb activity validated for children with cerebral palsy aged 5-16 years. The ChARM is freely available for use to clinicians and nonprofit organisations.
