Feasibility Study of a Therapeutic Mobility Summer Camp for Children with Severe Cerebral Palsy: Power Fun

Go Zika Go: feasibility study with modified motorized ride-on cars for the mobility of children with Congenital Zika Syndrome (CZS)

PURPOSE

To explore the feasibility of an intervention using modified ride-on cars in terms of acceptability and potential changes in goal attainment, mobility, social function, and participation of children with Congenital Zika Syndrome (CZS).

MATERIALS AND METHODS

A pre- and post-intervention feasibility study was conducted with children with CZS, levels IV and V of the Gross Motor Function Classification System (GMFCS). The intervention consisted of 12 weeks of training (3 times a week for 40 min per session) and 4 weeks of follow-up. The primary outcomes included adherence, satisfaction, and learning in mobility. Secondary outcomes encompassed goal attainment, mobility, social/cognitive function, and participation. Descriptive statistics were performed. To explore potential individual changes with the intervention, Wilcoxon test was used to analyze Pediatric Evaluation of Disability Inventory - Computer Adaptive Test (PEDI-CAT) data and Young Children's Participation and Environment Measure (YC-PEM)/Participation and Environment Measure for Children and Youth (PEM-CY), along with standard error measurements of the PEDI-CAT domains.

RESULTS

Four children participated (median age 4.75 years; two females: three at level V on the GMFCS). Adherence was 75% of the total intervention time, and family members reported being satisfied or very satisfied. Children showed gains in learning the use of the modified ride-on cars and an increase in goal attainment after the intervention. Individual changes were observed in the PEDI-CAT domains (mobility and social/cognitive), but there were no significant changes in participation outcomes.

CONCLUSIONS

Children with CZS at GMFCS levels IV and V can learn to use motorized ride-on cars, attainment goals, and experience satisfaction.

Effectiveness of wheeled mobility skill interventions in children and young people with cerebral palsy: A systematic review

AIM

To systematically review the effectiveness of wheeled mobility interventions in children and young people with cerebral palsy (CP).

METHOD

A systematic literature search was performed in MEDLINE, Embase, Cochrane Central Register of Controlled Trials, EBSCO, PEDro, and Web of Science using database-specific concepts such as 'child' and 'wheelchair'. Studies focusing on wheeled mobility skill interventions with participants aged 6 to 21 years with CP were included.

RESULTS

Twenty studies with 203 participants were included. The impact of wheeled mobility skill interventions was assessed on mobility skills (n = 18), activity and participation (n = 10), and quality of life (n = 3). No studies reported effects on stress, fatigue, and motivational aspects. Interventions included power wheelchair skill training (n = 12), computer-based training (n = 5), smart wheelchair training (n = 2), and manual wheelchair training (n = 1), showing positive wheeled mobility intervention effects. Study quality based on the Methodological Index for Non-Randomized Studies scale was 9 out of 16 and 14 out of 24 for non-comparative and comparative studies respectively. Risk of bias was serious-to-critical on the Risk of Bias in Non-Randomized Studies of Interventions.

INTERPRETATION

Wheeled mobility interventions showed promising beneficial effects on wheeled mobility, activity and participation, and quality of life for children and young people with CP. Future studies with structured and standardized training programmes and assessment tools are warranted to further accelerate the wheeled mobility skill acquisition process in this population.

WHAT THIS PAPER ADDS

Wheeled mobility interventions improve wheeled mobility skills in individuals with cerebral palsy. The mobility skill acquisition process benefits from structured and standardized training. Knowledge of the intervention effects on participation and quality of life is limited. Most studies had moderate quality of evidence because of methodological limitations.

Evaluation of pediatric-specific resources to support utilization of the Wheelchair Skills Training Program by the users of the resources: a descriptive qualitative study

BACKGROUND

Children's ability to engage in meaningful activities is positively influenced by their ability to move independently. Preliminary evidence in children suggests that wheelchair skills training improves wheelchair skills, which are important for independent mobility. The Wheelchair Skills Training Program is a standardized program to teach wheelchair skills. However, it is underutilized in pediatric rehabilitation settings. To increase its utilization, 3 pediatric-specific Wheelchair Skills Training Program resources related to indoor skills were developed (i.e., a storybook, four instructional posters, and a training workbook). This study aimed to describe occupational therapists' (OTs) and pediatric manual wheelchair users' (PMWUs) perceived satisfaction with the storybook, instructional posters and training workbook, and to explore their perceptions regarding the usability, relevance, and feasibility of these resources in pediatric rehabilitation settings.

METHODS

A descriptive qualitative design was used. Convenience samples of OTs and PMWUs were recruited in a rehabilitation center and affiliated schools. A focus group with OTs and semi-structured interviews with PMWUs were conducted by videoconference to obtain participants' feedback on the resource prototypes and suggestions for improvement. Data were deductively analyzed using the Framework method.

RESULTS

Eight OTs and 5 PMWUs expressed general satisfaction with the resources, describing them as usable, relevant, and feasible to integrate into wheelchair skills training with novice wheelchair users and younger children. All OTs and 3 PMWUs expressed the desire to use the resources for wheelchair skills training. Two PMWUs perceived the resources were not relevant to them because they already mastered the skills. The participants suggested minor modifications for improving the resources (e.g., more action in the story, increased precision of illustrations related to the characters' position in the wheelchair).

CONCLUSION

OTs and PMWUs were satisfied with the resources, perceiving them to be applicable for training wheelchair skills among young children and novice wheelchair users. The resources represent a concrete solution to facilitate the use of the Wheelchair Skills Training Program in pediatric rehabilitation settings. Additional resources are needed to better reach older and more experienced PMWUs (i.e., of intermediate and advanced skill levels).

Feasibility and Preliminary Effects of a 1-Week Vestibular Rehabilitation Day Camp in Children with Developmental Coordination Disorder

AIM

This pilot study investigated the feasibility and preliminary effects of an intensive 1-week day camp program for children with Developmental Coordination Disorder (DCD) that focused on vestibular rehabilitation.

METHODS

Ten participants (6-10 years) were assessed twice pre-intervention, post intervention, and at 8-week follow-up. Videonystagmography, Video Head Impulse Tests (vHIT), and Modified Emory Clinical Vestibular Chair Test (m-ECVCT) test were assessed at baseline. Outcomes measures were gaze stability (Dynamic Visual Acuity; DVA), functional gait (Functional Gait Assessment; FGA), balance (Sensory Organization Test), motor function (Bruininks-Oseretsky Test), and participation (Miller Function and Participation).

RESULTS

No abnormal results were detected from the videonystagmography, vHIT and m-ECVCT. There was a 100% attendance rate at the camp and assessment sessions. FGA scores significantly improved following intervention and changes were maintained at follow-up. The number of children with abnormal DVA scores decreased from 3 to 1 to 0 between pre-intervention, post-intervention, and follow-up. There were no significant changes in any of the other outcomes following intervention.

CONCLUSIONS

Intensive vestibular rehabilitation delivered in a day camp format is feasible and show positive preliminary effects on functional gait and dynamic visual acuity in children with DCD.

Evaluating a Therapeutic Powered Mobility Camp for Children with Severe Cerebral Palsy

Background. Children and youth with severe cerebral palsy (CP) have limited independent mobility, which affects opportunities for overall development. Purpose. To examine the effectiveness of Power Fun, a therapeutic powered mobility summer camp. Methods. A quasi-experimental, repeated-measure design was used, with participants acting as their own control. Twenty-four participants with severe CP (aged 7-20 years) attended Power Fun for three weeks, five days/week. Assessments of powered mobility skills and functional mobility goals were conducted three weeks before the camp (T1), at baseline (T2), postintervention (T3), and at three-week follow-up (T4). Findings. An analysis of variance results indicated significant improvements in powered mobility skills (F(1,22) = 56.61, p < 0.001, η²_p = 0.74) and functional mobility goals (F(1,58) = 80.17, p < 0.001, η²_p = 0.74), with 70% of goals achieved postintervention. A descriptive analysis revealed three learning profiles. Implications. This study provides initial evidence supporting the effectiveness of Power Fun as an intervention promoting powered mobility for children with severe CP, across a range of abilities.

The Development and Evaluation of the Powered Mobility Function Scale (PMFS) for Children and Adolescents with Cerebral Palsy

Aims: To describe the development and evaluation of a novel task-based measure of powered mobility function: the Powered Mobility Function Scale (PMFS).Methods: PMFS was developed in Hebrew in four phases, with feedback from clinicians and clients. Psychometric properties (inter-rater, test-retest reliability, concurrent, convergent and known-groups validity) were evaluated for N = 49 children and adolescents with Cerebral Palsy (11.1 ± 4.8y) using Powered Mobility Program (PMP), Gross Motor Function Classification System (GMFCS), Manual Ability Classification System (MACS) and Pediatric Evaluation of Disability Inventory Computer Adaptive Test (PEDI-CAT)Results: PMFS development involved 3 versions over three years. Inter-rater reliability was κ=0.75-0.95 (video/observation). Test-retest reliability was κ=0.93-0.96. Concurrent validity (PMP) was ρ=-0.84-to-0.96. Convergent validity (PEDI-CAT) was ρ=-0.47-to-0.70. Known-groups validity (GMFCS/MACS) demonstrated medium effect sizes (r = 0.33-0.46)Conclusions: PMFS is valid and reliable for measuring powered mobility function in children and adolescents with CP. Future validation of the English version of PMFS is warranted.

Effects of a powered mobility summer camp as perceived by school staff: a qualitative study

PURPOSE

Powered mobility has a positive effect on social skills, self-esteem and overall development of children with motor impairments, but almost all previous studies were conducted with pre-school children. The aim of this study was to explore change beyond mobility following a therapeutic powered mobility summer camp for school-aged children and adolescents with severe cerebral palsy, as perceived by school staff.

MATERIALS AND METHODS

The participants in the therapeutic camp, which ran for 3 weeks, 5 days a week, three times over the summers 2018-2019, were children ages 7-19 (median age 11) with severe cerebral palsy who needed assistance in mobility and had limited hand function. Following the intervention, 19 semi-structured audio-recorded interviews were conducted with school staff, then transcribed and thematically analyzed using an inductive qualitative descriptive design with a phenomenological theoretical framework.

RESULTS

Four overarching themes were identified: (1) "Every step you take: mastering new, sometimes unexpected, skills", (2) "Break on through to the other side: changes in behaviour", (3) "Make new friends (but keep the old): Boosting social behaviour" and (4) "I'm a believer: The journey through self-efficacy to empowerment".

CONCLUSIONS

The interviews showed the immediate positive influence of powered mobility for children who previously did not have independent mobility, following an intensive intervention. Changes in initiative, empowerment, social relationships and behaviour highlight the importance of self-generated mobility, regardless of whether independence was achieved. School-aged children with severe cerebral palsy seem to benefit from an intensive powered mobility intervention in areas other than mobility skills themselves.IMPLICATIONS FOR REHABILITATIONPowered mobility intervention seems to encourage activity and initiation among children and youth with severe CP.This research adds to the understanding of the effect powered mobility can have on social interaction and communication.Powered mobility might be a means to allow development, in addition to being an important end.

Exploring young children’s activity and participation change following 6 months’ power mobility experience

Introduction

This pre-post study explored the effect of children’s 6 months’ experience in one of four early power mobility devices.

Method

Satisfaction with parent-selected goal achievement was measured using the wheelchair outcome measure for young people and compared with the assessment of learning powered mobility use, as well as device expectation fulfilment ratings.

Results

Forty-six children with mobility limitations, aged 13–68 months (mean 40.40; SD 15.60) participated. The most common condition was cerebral palsy ( n = 33; 71.74%). The Wilcoxon signed rank test measured the positive change in goal achievement ( z = 4.90; P<0.001; r = 0.51). Fair to good statistically significant Spearman’s correlations were observed between power mobility skill and goal achievement, as well as parent and therapist device expectation scores ( rs = 0.48, 0.46 and 0.66, respectively; P<0.001). Parent and therapist ratings did not differ significantly. No statistically significant associations were found between goal achievement and child (age, diagnosis, abilities) or environmental factors (device, access method, loan length).

Conclusion

Children at all phases of power mobility skill, using various devices and access methods, can demonstrate activity and participation change following power mobility experience. This study adds validity evidence supporting the use of the wheelchair outcome measure for young people with young children by parent-proxy rating.

Exploring change in young children's power mobility skill following several months' experience

PURPOSE

To measure and compare progression in children's power mobility skill among process and task-based measures following a loan of one of four early power mobility devices. Additionally, to explore different power mobility learner groups and skill development trajectories.

METHODS

In this pre-post study, children were purposefully sampled and power mobility skill was measured from video taken pre-post several months' experience (mean 192.40; SD 42.79 days) using the Assessment of Learning Powered mobility use (ALP) and two task-based measures. Associations among power mobility skill measures were examined. Child and environmental factors influencing ALP phase at loan-end were explored.

RESULTS

Forty-six children aged 13 - 68 months (mean 40.40; SD 15.60) participated, with cerebral palsy being the most common condition (n = 33; 71.74%). ALP change scores ranged from -2 to +4 ALP phases (median 1.0). Wilcoxon signed rank test was significant for pre-post differences with a large effect size (z = 5.50, p < 0.001; r = 0.57). End-of-loan Spearman correlations between ALP and two task-based paediatric measures were excellent (r_s = 0.92). Kruskal-Wallis test revealed significant effect of device, access method, diagnostic group and communication abilities on loan-end ALP phase.

CONCLUSION

Positive change was demonstrated with most children (n = 39; 84.78%) changing at least one ALP phase during the study. Positive change was seen with children at all phases of tool-use, using all devices and access methods. Process and task-based measures were highly correlated, but differed in application for different learner groups. Different trajectories of skill development may be associated with different child profiles and access abilities.IMPLICATIONS FOR REHABILITATIONChildren at all phases of tool-use can demonstrate positive change in power mobility skill using different devices and switch as well as joystick access methodsThe Assessment of Learning Powered mobility use (ALP) is useful for assessing tool-use and learning process skills for young children across the power mobility skill continuum.Task-based measures may also be helpful for guiding training and recording progress; The Power Mobility Training Tool (PMTT) is most useful for children exploring cause-effect and direction (ALP Phases 1-5), while the Power Mobility Program (PMP) is most useful for functional learners and those progressing from exploring direction to functional use (ALP Phases 5-8).Access method may influence power mobility learning trajectory and training.
