Driving to Learn in a Powered Wheelchair: The Process of Learning Joystick Use in People With Profound Cognitive Disabilities

BCI move: exploring pediatric BCI-controlled power mobility

Introduction

Children and young people (CYP) with severe physical disabilities often experience barriers to independent mobility, placing them at risk for developmental impairments and restricting their independence and participation. Pilot work suggests that brain-computer interface (BCIs) could enable powered mobility control for children with motor disabilities. We explored how severely disabled CYP could use BCI to achieve individualized, functional power mobility goals and acquire power mobility skills. We also explored the practicality of pediatric BCI-enabled power mobility.

Methods

Nine CYP aged 7-17 years with severe physical disabilities and their caregivers participated in up to 12 BCI-enabled power mobility training sessions focused on a personalized power mobility goal. Goal achievement was assessed using the Canadian Occupational Performance Measure (COPM) and Goal Attainment Scaling (GAS). The Assessment for Learning Powered Mobility (ALP) was used to measure session-by-session power mobility skill acquisition. BCI set-up and calibration metrics, perceived workload, and participant engagement were also reported.

Results

Significant improvements in COPM performance (Z = -2.869, adjusted p = 0.012) and satisfaction scores (Z = -2.809, adjusted p = 0.015) and GAS T scores (Z = -2.805, p = 0.005) were observed following the intervention. ALP scores displayed a small but significant increase over time (R 2 = 0.07-0.19; adjusted p = <0.001-0.039), with 7/9 participants achieving increased overall ALP scores following the intervention. Setup and calibration times were practical although calibration consistency was highly variable. Participants reported moderate workload with no significant change over time (R 2 = 0.00-0.13; adjusted p = 0.006-1.000), although there was a trend towards increased frustration over time(R 2 = 0.13; adjusted p = 0.006).

Discussion

Participants were highly engaged throughout the intervention. BCI-enabled power mobility appears to help CYP with severe physical disabilities achieve personalized power mobility goals and acquire power mobility skills. BCI-enabled power mobility training also appears to be practical, but BCI performance optimization and skill acquisition may be needed to translate this technology into clinical use.

The IndieTrainer system: a small-scale trial exploring a new approach to support powered mobility skill acquisition in children

The IndieTrainer system, consisting of a mobility device and video-based gamified training modules, was developed to assist children in attaining power wheelchair (PWC) skills. The purposes of this small-scale trial were to explore the use of the IndieTrainer system to provide PWC skills training and document parental satisfaction with the IndieTrainer system. We hypothesized that PWC skills training provided using the IndieTrainer system would result in improvements in both children's understanding of how to use a PWC and their PWC skill execution, and that parental satisfaction would be high. An open-label, single-arm trial was conduct as follows: (a) Baseline testing (T0); (b) A 3-week intervention consisting of two, 60-min-PWC skills training sessions per week; (c) Post-intervention testing (T1); and (d) A single session retention trial held 4 weeks after completion of the intervention (T2). Outcome measures included the Assessment of Learning Powered mobility use (ALP), Wheelchair Skills Checklist (WSC), Canadian Occupational Performance Measure (COPM), and Client Satisfaction Questionnaire-8 (CSQ-8). 25 child/parent dyads participated. Between T0 and T1, statistically significant differences (p-value <.0001) with large effect sizes in mean ALP and WSC scores (ALP: d = 3.14; WSC: d = 3.25) and COPM performance and satisfaction scores (Performance: d = 4.66; Satisfaction: d = 3.24) were achieved. Mean T1 total CSQ-8 score was 31.52/32. At T2, all children maintained or improved their T1 ALP and WSC scores. This study provides initial support for the usability and feasibility of the IndieTrainer system. Futhermore, larger scaled studies using more rigorous research designs are indicated.

The IndieTrainer system: a clinical trial protocol exploring use of a powered wheelchair training intervention for children with cerebral palsy

OBJECTIVE

The IndieTrainer system, comprised of both a mobility device and gamified training modules, was developed to aid powered wheelchair (PWC) skills acquisition in children with cerebral palsy (CP). The aims of this small-scale study are to: explore use of the IndieTrainer system to improve PWC skills in children who have CP and document parental/caregiver perceptions of, and satisfaction with, the IndieTrainer system.

METHOD

This small-scale study is an open-label single-arm clinical trial involving a three-week PWC training intervention consisting of two 60-minute training sessions per week. A single session retention trial will be held four weeks after the completion of the intervention period. All research activities will take place in-person in a laboratory-based setting located within a university. Twenty-five child-parent/caregiver dyads will participate in the study. Each child participant will be 3 to 21 years of age and have a diagnosis of CP or other similar condition. The Assessment of Learning Powered mobility use will be the primary outcome measure. Secondary outcome measures will include the Wheelchair Skills Checklist, the Canadian Occupational Performance Measure, the Customer Satisfaction Questionnaire-8, and a qualitative interview. Data analyses will involve one-way repeated measures ANOVAs followed by paired samples t-tests with Bonferroni adjustments.

IMPACT

The IndieTrainer system allows children to explore and use power mobility in their own manual wheelchair and was designed to meet the needs of power mobility learners across the continuum of learning. It is the first PWC training system to optimize learning for early learners who do not yet understand cause and effect concepts.

Characterization of Fine Motor and Visual Motor Skills in Aicardi-Goutières Syndrome

Aicardi-Goutières syndrome is a genetic inflammatory disorder resulting in dispersed neurologic dysfunction. Despite a recognition of overall motor impairment, fine and visual motor skills are undercharacterized. We hypothesize that there is a spectrum of fine and visual motor skills in the Aicardi-Goutières syndrome population as captured by a standard outcome measure, the Peabody Developmental Motor Scales (PDMS-2), which will be proportional to overall disease severity.In a cohort of 74 subjects, the Peabody Developmental Motor Scales-2 grasping and visual-motor integration subtests were administered concurrently with the Aicardi-Goutières syndrome Severity Scale (severe [range 0-3], moderate [range 4-8], and attenuated [range 9-11]). The cohort was also compared by genotype and performance as defined by raw scores. The distribution of Peabody Developmental Motor Scales-2 scores within a genotype was assessed by interquartile ranges (IQRs).Peabody Developmental Motor Scales-2 grasping and visual-motor integration performance was the least variable in the TREX1-cohort (IQR: 10.00-12.00) versus the SAMHD1 and IFIH1 cohorts (IQR: 51.00-132.00 and 48.50-134.00, respectively). Neurologic severity highly correlated with both fine and visual motor skills (Spearman correlation: r = 0.87, 0.91, respectively). A floor effect (lowest 10% of possible scores) was observed within the severe cohort (n = 32/35), whereas a ceiling effect (top 10%) was observed in the attenuated cohort (n = 13/17).This study characterized the spectrum of fine and visual motor function in the Aicardi-Goutières syndrome population, which correlated with overall neurologic dysfunction. The Peabody Developmental Motor Scales-2 grasping and visual-motor integration showed promise as potential assessment tools in moderate and attenuated Aicardi-Goutières syndrome cohorts. A better understanding of fine and visual motor function in this population will benefit clinical care and clinical trial design.

Technology for Adults with Intellectual Disability: Secondary Analysis of a Scoping Review

Background. Technologies are embedded in all daily life activities and are utilized by occupational therapy practitioners to facilitate participation; evidence on technology for adults with intellectual disability (ID) can support practice with the population. Purpose. Summarize the evidence on technology to support adults with ID. Method. Secondary analysis of a scoping review of articles published between 2002 and 2018. Articles in the original scoping review addressed participation, assessment, or interventions with adults with ID. Authors completed a secondary analysis of 159 articles to identify articles with information on technology. Findings. In total, 56 articles met the inclusion criteria. Technology categories were cognitive supports, mainstream technologies, supplemental communication, aids for daily living, seating and mobility, control interfaces, and preparatory technologies. Implications. This secondary analysis demonstrates the range of evidence identifying technology as a key support, the impacts of the proliferation of technologies, and the need for occupational therapy practitioners to advocate for accessible technologies.

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.

Effectiveness of the miWe Simulator Training on Powered Wheelchair-driving Skills: A Randomized Controlled Trial

OBJECTIVES

To evaluate the effectiveness of a home-based simulator training, in comparison with a videogame-based training, in terms of powered wheelchair driving skills, skills use in a real-world setting, and driving confidence.

DESIGN

Single-blinded randomized controlled trial.

SETTING

Community.

PARTICIPANTS

New powered wheelchair users (N=47) randomly allocated to simulator group (n=24, 2 drop-out) and control group (n=23, 3 drop-out).

INTERVENTIONS

The miWe wheelchair simulator (simulator group) or a kart driving videogame (control group) was setted-up at participants' homes (computer + joystick). They were instructed to use it at least 20 minutes every 2 days, during a period of 2 weeks.

PRIMARY OUTCOME MEASURE(S)

Assessments were done at baseline (T1) and post-training (T2) using the Wheelchair Skills Test Questionnaire (WST-Q, version 4.1), Wheelchair Confidence Scale (WheelCon), Assistive Technology Outcomes Profile for Mobility, and Life-Space Assessment (LSA). The time necessary to complete 6 WST tasks was measured with a stopwatch.

RESULTS

Participants of the simulator group significantly increased their WST-Q capacity score at T2 by 7.5% (P<.05), whereas the control group remained at the same score (P=.218). Participants of both groups rolled backward and went through a door significantly faster at T2 (P=.007; P=.016), but their speed did not change for the other skills. The WheelCon score significantly increased after training (+4% for the control group and +3.5% for the simulator group, P=.001). There was no T1-T2 difference between groups for the WST-Q performance scores (P=.119), the ATOP-Activity (P=.686), the ATOP-Participation scores (P=.814), and the LSA score (P=.335). No adverse events or side effects were reported during data collection or training.

CONCLUSIONS

Participants of both groups improved some skills and their wheelchair driving confidence. The simulator training group also demonstrated a modest post-training gain in their WST-Q capacity, but more studies would be needed to explore the long-term effects of the McGill immersive wheelchair simulator (miWe) simulator on driving skills.

Early Introduction of Power Mobility Devices for Children with Fukuyama Congenital Muscular Dystrophy and Its Psychological Impact on Caregivers: A Case Report

Recently, motorized mobility devices (or power mobility devices (PMDs)) have been introduced for infants and toddlers who lack the means for self-mobility. Previous reports have primarily focused on PMDs for individuals with cerebral palsy. Few have explored PMDs for individuals with neuromuscular diseases who have intellectual disabilities. This report presents a case study of the early introduction of a PMD for an infant with Fukuyama congenital muscular dystrophy and presents the results of an interview with the father regarding psychological aspects and the child's manipulative abilities. The PMD was introduced at the age of 1 year and 10 months, and the changes during the 19 months after the introduction were evaluated six times, using the Assessment of Learning Powered mobility use tool (ALP). A semi-structured interview with the father was conducted 19 months after the introduction. The ALP evaluation and the interview were conducted by one physical therapist and two physical therapy students, and the results were shared with the hospital's physical therapist and nurses at the nursing facility. This report provides a basis for expanding the scope of PMD use and for considering the family's involvement, especially for the child.

Relationships between Cognitive Functioning and Powered Mobility Device Use: A Scoping Review

BACKGROUND

Powered mobility devices (PMD) promote independence, social participation, and quality of life for individuals with mobility limitations. However, some individuals would benefit from PMD, but may be precluded access. This is particularly true for those with cognitive impairments who may be perceived as unsafe and unable to use a PMD. This study explored the relationships between cognitive functioning and PMD use. The objectives were to identify cognitive functions necessary to use a PMD and describe available PMD training approaches.

METHODS

A scoping review was undertaken.

RESULTS

Seventeen studies were included. Four examined the predictive or correlational relationships between cognitive functioning and PMD use outcomes with intellectual functions, visual and visuospatial perception, attention, abstraction, judgement, organization and planning, problem solving, and memory identified as having a relation with PMD use outcome in at least one study. Thirteen others studied the influence of PMD provision or training on users' PMD capacity and cognitive outcomes and reported significative improvements of PMD capacities after PMD training. Six studies found improved cognitive scores after PMD training.

CONCLUSIONS

Cognitive functioning is required to use a PMD. Individuals with heterogeneous cognitive impairment can improve their PMD capacities. Results contribute to advancing knowledge for PMD provision.

Powered mobility interventions for very young children with mobility limitations to aid participation and positive development: the EMPoWER evidence synthesis

BACKGROUND

One-fifth of all disabled children have mobility limitations. Early provision of powered mobility for very young children (aged < 5 years) is hypothesised to trigger positive developmental changes. However, the optimum age at which to introduce powered mobility is unknown.

OBJECTIVE

The aim of this project was to synthesise existing evidence regarding the effectiveness and cost-effectiveness of powered mobility for very young children, compared with the more common practice of powered mobility provision from the age of 5 years.

REVIEW METHODS

The study was planned as a mixed-methods evidence synthesis and economic modelling study. First, evidence relating to the effectiveness, cost-effectiveness, acceptability, feasibility and anticipated outcomes of paediatric powered mobility interventions was reviewed. A convergent mixed-methods evidence synthesis was undertaken using framework synthesis, and a separate qualitative evidence synthesis was undertaken using thematic synthesis. The two syntheses were subsequently compared and contrasted to develop a logic model for evaluating the outcomes of powered mobility interventions for children. Because there were insufficient published data, it was not possible to develop a robust economic model. Instead, a budget impact analysis was conducted to estimate the cost of increased powered mobility provision for very young children, using cost data from publicly available sources.

DATA SOURCES

A range of bibliographic databases [Cumulative Index to Nursing and Allied Health Literature (CINHAL), MEDLINE, EMBASE™ (Elsevier, Amsterdam, the Netherlands), Physiotherapy Evidence Database (PEDro), Occupational Therapy Systematic Evaluation of Evidence (OTseeker), Applied Social Sciences Index and Abstracts (ASSIA), PsycINFO, Science Citation Index (SCI; Clarivate Analytics, Philadelphia, PA, USA), Social Sciences Citation Index™ (SSCI; Clarivate Analytics), Conference Proceedings Citation Index - Science (CPCI-S; Clarivate Analytics), Conference Proceedings Citation Index - Social Science & Humanities (CPCI-SSH; Clarivate Analytics), Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects (DARE), NHS Economic Evaluation Database (NHS EED), Health Technology Assessment (HTA) Database and OpenGrey] was systematically searched and the included studies were quality appraised. Searches were carried out in June 2018 and updated in October 2019. The date ranges searched covered from 1946 to September 2019.

RESULTS

In total, 89 studies were included in the review. Only two randomised controlled trials were identified. The overall quality of the evidence was low. No conclusive evidence was found about the effectiveness or cost-effectiveness of powered mobility in children aged either < 5 or ≥ 5 years. However, strong support was found that powered mobility interventions have a positive impact on children's movement and mobility, and moderate support was found for the impact on children's participation, play and social interactions and on the safety outcome of accidents and pain. 'Fit' between the child, the equipment and the environment was found to be important, as were the outcomes related to a child's independence, freedom and self-expression. The evidence supported two distinct conceptualisations of the primary powered mobility outcome, movement and mobility: the former is 'movement for movement's sake' and the latter destination-focused mobility. Powered mobility should be focused on 'movement for movement's sake' in the first instance. From the budget impact analysis, it was estimated that, annually, the NHS spends £1.89M on the provision of powered mobility for very young children, which is < 2% of total wheelchair service expenditure.

LIMITATIONS

The original research question could not be answered because there was a lack of appropriately powered published research.

CONCLUSIONS

Early powered mobility is likely to have multiple benefits for very young children, despite the lack of robust evidence to demonstrate this. Age is not the key factor; instead, the focus should be on providing developmentally appropriate interventions and focusing on 'movement for movement's sake'.

FUTURE WORK

Future research should focus on developing, implementing, evaluating and comparing different approaches to early powered mobility.

Using a child's power mobility learner group to tailor power mobility interventions: a case series

PURPOSE

The purpose of this case series was to explore using a child's power mobility learner group (exploratory, operational, or functional) to tailor power mobility interventions. Materials and methods: Five cases representing 2 exploratory power mobility learners, 2 operational power mobility learners, and 1 functional power mobility learner are presented. In each case, the participant's power mobility learner group was used to tailor his/her power mobility intervention program including establishing desired outcomes/goals of power mobility use, selecting outcome measures, determining the power mobility device to be used, and identifying the specific intervention strategies to be used.

RESULTS

All participants demonstrated improvements in power mobility device use following provision of the tailored intervention. Cases involving use of the Canadian Occupational Performance Measure demonstrated clinically significant improvements in post-intervention scores.

CONCLUSIONS

These cases illustrate a means to tailor power mobility interventions that may potentially optimise learning by providing an environment and conditions that meet each child's specific needs. The short-term and long-term gains made by the children in these cases warrants a controlled study exploring the use of a child's power mobility learner group to tailor power mobility interventions.IMPLICATIONS FOR REHABILITATIONUsing a child's power mobility learner group to tailor power mobility intervention may potentially optimise learning by providing an environment and conditions that meet each child's specific needs.Children across the learning continuum represented by the 3 power mobility learner groups (exploratory, operational, and functional) may benefit from power mobility interventions.Using a child's power mobility learner group to tailor power mobility interventions may support translation research knowledge into clinical practice.

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.

Occupational Therapy-Related Assessments for Adults With Intellectual Disability: A Scoping Review

IMPORTANCE

Occupational therapy practitioners use structured assessment tools to gather information from adults with intellectual disability (ID) in order to develop the occupational profile, guide occupational therapy intervention, and assess change over time.

OBJECTIVE

To identify occupational therapy-related tools in the peer-reviewed literature for use in practice with adults with ID.

DATA SOURCES

Peer-reviewed literature published between January 2002 and January 2018 included in CINAHL, PsycINFO, PubMed, and Scopus. Study Selection and Data Collection: The review included articles that had information on occupational therapy-related assessment with adults 18 yr or older who had primary or co-occurring ID.

FINDINGS

Fifty-eight articles identified 73 occupational therapy-related assessment tools.

CONCLUSIONS AND RELEVANCE

This scoping review identified a broad range of assessment tools in the occupational therapy domain that are appropriate for adults with ID, some of which may be unfamiliar to occupational therapy practitioners. What This Article Adds: This scoping review provides occupational therapy practitioners with a summary of occupational therapy-related assessment tools for adults with ID and an assessment reference guide.

Evidence to Inform Occupational Therapy Intervention With Adults With Intellectual Disability: A Scoping Review

IMPORTANCE

Occupational therapy practitioners use a range of habilitative and compensatory approaches to teach new skills or modify tasks and environments to address occupational performance among adults with intellectual disability (ID); therefore, they must identify and use available evidence to guide intervention planning.

OBJECTIVE

To summarize the scope of evidence that can inform occupational therapy intervention with adults with primary or comorbid ID.

DATA SOURCES

Articles published in peer-reviewed journals between January 2002 and January 2018 and indexed in PubMed, CINAHL, PsycINFO, and Scopus. Study Selection and Data Collection: A total of 159 articles met inclusion criteria and contained information on occupational therapy intervention with adults ages 18 yr or older with primary or coexisting ID.

FINDINGS

Fifty-seven of the 159 articles focused on intervention to address occupational performance outcomes (i.e., employment, self-care, leisure and social interaction, community participation).

CONCLUSIONS AND RELEVANCE

A wide range of literature is available to support occupational therapy intervention with adults with ID. Occupational therapy practitioners may be less knowledgeable about this evidence because much of it is located in non-occupational therapy or international journals. What This Article Adds: This scoping review provides occupational therapy practitioners with evidence to support high-quality occupational therapy intervention with adults with ID.

"Make it fun": a qualitative study exploring key aspects of power mobility interventions for children

PURPOSE

Research suggests there are three groups of paediatric power mobility learners: exploratory, operational and functional. The purpose of this modified grounded theory study was to explore the key aspects of power mobility interventions for children in each of these paediatric power mobility learner groups.

MATERIALS AND METHODS

Data were gathered through face-to-face interviews conducted in-person or via Zoom^®. Three stakeholder groups were interviewed: (1) children ages 8-18 years who used a power wheelchair (PWC); (2) parents whose children (≤18 years of age) used a PWC; and (3) therapists/therapist researchers experienced in paediatric power mobility. An interview guide was created for each stakeholder group. Interviews were transcribed verbatim and an initial coding scheme was used to identify intervention activities specific to each learner group. Data for each learner group were then coded to reflect the essence of each intervention activity. Finally, patterns within the data were identified and codes were collapsed into thematic categories reflecting the key aspects of intervention for each learner group.

RESULTS

A total of 29 participants (nine children, seven parents and 13 therapists) took part in the study. Key aspects of power mobility interventions for each learner group, as well as fundamental aspects of power mobility intervention applicable to all learner groups, emerged in the data.

CONCLUSIONS

This study highlights both the similarities (fundamental aspects) and differences (key aspects targeting the specific needs of each learner group) of power mobility interventions for children in each of the three power mobility learner groups.Implications for RehabilitationThere are both similarities (fundamental aspects) and differences (key aspects targeting the specific needs of each learner group) in the needs of children in each of the three power mobility learner groups.Key aspects of power mobility interventions vary for children in each of the three paediatric power mobility learner groups and correspond with the learning needs of each power mobility learner group.The findings of this study will help clinicians and researchers to tailor power mobility interventions to meet the unique needs of children in each power mobility learner group.

Beginning power mobility: parent and therapist perspectives

PURPOSE

To explore parent and therapist experiences of early power mobility following participation in a Power Mobility Day - a 60-90 min play-based session where children with mobility limitations (<6 years of age) experienced four different early power mobility devices.

METHOD

Participants were purposefully selected from parents and therapists who took part in Power Mobility Days as part of a larger cross-sectional study. One semi-structured interview with each participant was conducted via telephone. Interviews were audio-recorded, transcribed, and analyzed using a content analysis approach.

RESULTS

Of 35 adults approached, 11 parents and 11 occupational or physical therapists completed interviews averaging 20 min (range 10-45 min), one week to three months after the session. Participants were parents or therapists of children aged 12 to 48 months of age with a variety of neuromotor diagnoses from different areas of the province. The overarching theme Empowering Children and Families to Explore was developed from themes: Earlier Experiences; A Novel Introduction; and Moving Forward.

CONCLUSION

Power Mobility Days provided a welcoming and inclusive child- and family-led introduction to power mobility. This novel approach may help change both therapists' and families' perception of child potential and perspectives on power mobility as an intervention.IMPLICATIONS FOR REHABILITATION:Exploratory sessions can provide a novel introduction to power mobility interventions.Child enjoyment has a reciprocal impact on family engagement with early power mobility.Experiential child- and family-led learning can increase awareness of power mobility options and possibilities.

Inter-rater reliability of the assessment of learning powered mobility use, version 2.0, when applied with children and adults engaged in Driving to Learn in a powered wheelchair

INTRODUCTION

The Assessment of Learning Powered mobility use (ALP) tool including the ALP instrument and facilitating strategies, was developed for Driving to Learn. This therapeutic intervention aims to provide children and adults who have profound cognitive disabilities with opportunities to learn tool use through powered mobility practise. To allow for longer intervention periods, a partnership was developed between professionals supervising Driving to Learn and persons accompanying children or adults to their practice sessions. Accompanying persons (relatives or assistants) gradually took on shared responsibility for applying the intervention and conducting assessments with the ALP-instrument. The aim of this study was to test the inter-rater reliability of the ALP-instrument version 2.0 as applied in this novel partnership in assessment and intervention.

METHOD

A psychometric analysis compared pair-wise assessments with the ALP-instrument version 2.0, made independently by professional supervisors and accompanying persons following each Driving to Learn session. Weighted kappa statistic was used to compare the matched pair ordinal data.

RESULTS

Eight professional supervisors and 22 accompanying persons independently completed assessments with the ALP-instrument after 55 sessions with six children and five adults, who each participated in five Driving to Learn sessions. When the scores from the 55 pairs of assessments were compared, a weighted kappa value of 0.85 was obtained, indicating very good inter-rater reliability between the two rater groups.

CONCLUSION

The resulting inter-rater reliability suggests that it is reliable to implement the ALP-instrument as part of partnership in intervention between supervisors and accompanying persons. Provision of longer periods of Driving to Learn is possible when those who accompany the child or adult are able to gradually assume responsibility for practice and assessment under the supervision of a professional. This partnership approach enables children and adults with multiple and complex disabilities to practise and learn in accordance with their conditions and needs.

Enhanced Steering and Drive Adaptations of Modified Ride-On Toy Cars for Improved Directional Control in Very Young Children With Severe Multiple Developmental Impairments

Background and Purpose: One emerging power mobility device (PMD) option that has gained recognition as a means for a cost-effective introduction to power mobility for young children is the battery powered modified ride-on toy car. Many groups, nationally and internationally, have been modifying battery powered ride-on toy cars by adding seating support and a large center placed push button switch for motor activation. The purpose of this technical report is to introduce an enhanced steering and drive system based on proportional control through a joystick. Key Points: This report offers (1) a technical description of these modifications that allow directional steering and programmable starting and driving velocity, (2) an example of a modified ride on toy, including common seating modifications, and (3) a short summary of results from a group of 7 children under the age of six with complex, severe disabilities. Clinical Impact: Although proportional joystick modifications are more complex than the common single switch activation, they allow children greater control to achieve self-initiated, self-directed movement that allow play, peer interaction, and exploration in their natural environments, even in the most highly complex cases. All seven children were able to intentionally self-initiate activation of the modified ride-on car and experience the subsequent movement.

Changes in Electroencephalography Activity in Response to Power Mobility Training: A Pilot Project

Purpose: The purposes of this pilot project were to examine the impact of power mobility training on (1) electroencephalography (EEG) activity in children with severe cerebral palsy (CP) and (2) power mobility skill acquisition. Method: A single-subject A-B-A-B research design with a 5-week duration for each phase (20 wk total) was replicated across three participants with severe CP (Gross Motor Function Classification System Level V). Data related to the target behaviour, as represented by EEG activity, were collected each week. Power mobility skills were assessed using the Canadian Occupational Performance Measure (COPM), the Wheelchair Skills Checklist (WSC), and the Assessment of Learning Powered mobility use (ALP). Weekly power mobility training was provided during the intervention phases. EEG data were analyzed by means of three measurement metrics (power spectral density, mutual information, and transfer entropy). Results: All three participants demonstrated changes in activation in frontoparietal EEG recordings and clinically significant improvements in power mobility skill acquisition as measured by the COPM as well as by the ALP and WSC. Conclusions: Power mobility training appeared to affect both neuroplastic and skill acquisition. Combining the use of EEG with direct therapist-observation measurement tools may provide a more complete understanding of the impact of power mobility training on children with severe CP.

Computational Thinking and Robotics: A Teaching Experience in Compulsory Secondary Education with Students with High Degree of Apathy and Demotivation

In present and future society, all individuals must be able to face the problems, risks, advantages and opportunities that will arrive with new paradigms in the labour market, social relations and technology. To reach this goal, a quality and inclusive education together with a proper and complete formation in technology (communications, robotics, programming, computational thinking (CT), etc.) must be imparted at all educational levels. Moreover, all individuals should have the same opportunities to develop their skills and knowledge, as stated in Goal 4 of the Sustainable Development Goals, Sustainable Education. Following this trend, in the present work, a practical experience about how to teach CT using robotics is developed, showing the results and evaluation of the lessons on robotics taught to students in their 4th year of compulsory secondary education, and where the students showed a high degree of apathy and demotivation. The teaching unit was based on an action research approach that includes a careful selection of pedagogical techniques and instruments to attract and keep the attention and interest of the students. In addition to the robotics lessons, a previous computational thinking training with Blockly Games was carried out, which contributed to noticeably increase the students motivation and to introduce them to the programming of robots. Moreover, gamification was used to motivate and evaluate the individual knowledge, and the students were required to present the work performed through a final project. The individual needs of the students were fulfilled with a daily monitoring. The results show that the pedagogical techniques, instruments and evaluation were adequate to increase the motivation of the students and to obtain a significant learning, showing how the teaching of CT may attract students that have lost interest and motivation, while providing them with abilities that will be essential for the learning throughout life.

American and Canadian therapists' perspectives of age and cognitive skills for paediatric power mobility: a qualitative study

Purpose: To explore the views of paediatric occupational therapists and physical therapists in Canada and the USA related to (1) the rationale for the age at which power mobility is considered for children and (2) the cognitive skills considered when trialling power mobility.Materials and methods: This study was part of a larger web-based survey study and analyzed responses to two open-ended survey questions: one related to age and one related to cognitive skills. Data were analyzed using the constant comparative method.Results: Analysis revealed four unique themes in the question related to age: (1) 'Power Mobility Should be Introduced at a Specific Age or Stage'; (2) 'Child Requirements'; (3) 'Developmental Impact of All Forms of Independent Mobility'; and (4) 'Benefits of Power Mobility'. In the question concerning cognitive skills, two unique themes were identified: 'Cognitive Skill Requirements?' and 'Non-Cognitive Requirements'. Two additional themes were identified in both questions: ('Non-child Requirements' and 'Power Mobility Trials, Use, and Options Are Dependent on Age and Goal').Conclusions: Data indicate wide variability in respondents' views related to the provision of power mobility. Additional research is needed to explore both therapists' reasoning regarding power mobility use for children and how to best facilitate knowledge translation in this area.Implications for RehabilitationWide variability exists related to the provision of power mobility for children.Children's age or stage in life influences therapists' consideration of power mobility.Many respondents considered cognitive skills when trialling power mobility but some did not.

'Power in Mobility': parent and therapist perspectives of the experiences of children learning to use powered mobility

AIM

The aim of this study was to gain insights, from the perspectives of both parents and pediatric therapists, into the experiences of children learning to use a power mobility device.

METHOD

The purposive sample included 33 participants: 14 parents of children who were learning, or had learned, to use a power mobility device and 19 pediatric occupational therapists or physical therapists. Data were gathered face-to-face via seven focus groups consisting of either parents or therapists, and eight one-on-one interviews. Data were analyzed using the constant comparative method.

RESULTS

Three main themes were identified: (1) 'Power in mobility' described how learning to use powered mobility changed more than just a child's locomotor abilities; (2) 'There is no recipe' revealed how learning to use powered mobility occurred along an individualized continuum of skills that often unfolded over time in a cyclical process; (3) 'Emotional journey' explored how learning to use powered mobility was an emotionally charged undertaking for all those involved.

INTERPRETATION

Learning to use a power mobility device is a complex process that often requires perseverance and determination on the part of the child, family, and therapist.

WHAT THIS PAPER ADDS

Powered mobility use impacts more than just a child's locomotor abilities. Learning to use a power mobility device is a highly individualized process. Learning to use powered mobility may be an emotionally charged process.

Power mobility skill progression for children and adolescents: a systematic review of measures and their clinical application

AIM

To identify and critically appraise standardized measures of power mobility skill used with children (18y or younger) with mobility limitations and explore the measures' application for 'exploratory', 'operational', and 'functional' learners.

METHOD

Five electronic databases were searched along with hand-searching for peer-reviewed articles published in English to July 2017 (updated 31st August 2017). Key terms included power(ed) mobility, power(ed) wheelchair, and database-specific terms. Studies included at least one child with a disability, and a detailed description of the measure of power mobility skill. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was followed with inclusion criteria set a priori. Two reviewers independently screened titles, abstracts, and full-text articles.

RESULTS

Of 96 titles, 24 articles met inclusion criteria, describing nine measures of power mobility skill. The Wheelchair Skills Checklist, the Powered Mobility Program (PMP), and the Power Mobility Training Tool were augmented by three adaptations of the PMP. Two additional measures were further developed to create a third, the Assessment of Learning Powered mobility use. Validity evidence related primarily to content development while reliability evidence was reported on only two measures.

INTERPRETATION

All measures are in the initial stages of development and testing. Research investigating the measures' appropriateness for different types of learners and environments is warranted.

WHAT THIS PAPER ADDS

There are four distinct measures of paediatric power mobility skill: three task-based, one process-based. Power mobility learners may be divided into three groups: exploratory, operational, and functional. Application of measures of power mobility skill differs for these three groups.

Power Mobility Training for Young Children with Multiple, Severe Impairments: A Case Series

AIMS

Young children with neurodevelopmental conditions are often limited in their ability to explore and learn from their environment. The purposes of this case series were to (1) describe the outcomes of using an alternative power mobility device with young children who had multiple, severe impairments; (2) develop power mobility training methods for use with these children; and (3) determine the feasibility of using various outcome measures.

METHODS

Three children with cerebral palsy (Gross Motor Function Classification System Levels IV, V, and V) ages 17 months to 3.5 years participated in the case series. Examination included the Pediatric Evaluation of Disability Inventory-Computer Adaptive Test (PEDI-CAT) and the Dimensions of Mastery Questionnaire (DMQ). An individualized, engaging power mobility training environment was created for each participant. Intervention was provided for 60 minutes per week over 12 weeks.

RESULTS

All participants exhibited improvements in power mobility skills. Post-intervention PEDI-CAT scores increased in various domains for all participants. Post-intervention DMQ scores improved in Participants 1 and 2.

DISCUSSION

The participants appeared to make improvements in their beginning power mobility skills. Additional research is planned to further explore the impact of power mobility training in this unique population.

Cognitive impairment and assistive devices: Outcomes and adverse effects

Purpose

The goal of this review was to investigate the relationship between cognitive impairment and assistive device use in elderly persons.

Methods

English-language articles for people aged 65 and over were identified by searching MEDLINE and Embase (1985–June 2015) with the keywords “self-help devices” and “cognition disorders” and relevant synonyms. Bibliographies of retrieved articles were also examined; 510 articles were selected for further evaluation. Abstracts of the remaining articles were evaluated and all of the studies that concerned one or more of the following criteria were included: geriatric, long-term care residents or cognitively impaired patients using assistive devices that addressed benefits, risks, adverse effects, or other problems. Ultimately, 15 articles were analyzed and included in the review.

Results

Very few good-quality studies that specifically addressed the research question were found. We found that cognitively impaired elderly patients were more likely to use assistive devices ineffectively than cognitively intact elders. In addition, the literature describes promising approaches to assistive device training and technologies to accommodate cognitive impairment in this population.

Conclusion

The evidence basis for recommendations and training for assistive devices for cognitively impaired elders is weak. More research is needed on safety and effectiveness of devices for this population.

Upper extremity neuro-rehabilitation through the use of power mobility

Power mobility is typically used as an accommodative form of assistive technology allowing individuals with impaired ambulation to remain mobile. While research has focused on the cognitive development and social benefits of power mobility for individuals with developmental disabilities, research is lacking on using this technology to rehabilitate physical dysfunction. Recent technology, such as robot-mediated neuro-rehabilitation, is proving effective in upper extremity rehabilitation, but lacks the movement feedback of power mobility. This article presents a case study of a client with cerebral palsy who experienced severe neural impairment following a motor vehicle accident. As a previous power mobility user, the client identified returning to using power mobility with the affected upper extremity as a key functional goal. This case study describes the series of steps that returned the client to independent mobility and increased upper extremity function.

Taking Control: An Exploratory Study of the Use of Tilt-in-Space Wheelchairs in Residential Care

Tilt-in-space (TIS) wheelchairs are common in residential care, but little empirical evidence exists regarding how they are used by residents and staff in these settings. As part of a larger study exploring the use of wheeled mobility in these facilities, we conducted a substudy to examine how TIS wheelchairs are used in practice and to explore the experiences of the residents who use them. We conducted a series of three participant observations and interviews with 6 residents or their family members and interviewed 10 staff. Our analysis identified taking control as the main overarching theme, subsuming two subthemes: promoting comfort and mobilizing to participate. Findings suggest that power TIS wheelchairs enable user control, whereas manual TIS wheelchairs promote staff control. These findings illustrate how TIS wheelchairs may enable or inhibit occupational engagement and suggest that vigilance is necessary to prevent their use as a restraint.

Joystick-controlled video console game practice for developing power wheelchairs users' indoor driving skills

[Purpose] This study aimed to determine the effectiveness of joystick-controlled video console games in enhancing subjects’ ability to control power wheelchairs. [Subjects and Methods] Twenty healthy young adults without prior experience of driving power wheelchairs were recruited. Four commercially available video games were used as training programs to practice joystick control in catching falling objects, crossing a river, tracing the route while floating on a river, and navigating through a garden maze. An indoor power wheelchair driving test, including straight lines, and right and left turns, was completed before and after the video game practice, during which electromyographic signals of the upper limbs were recorded. The paired t-test was used to compare the differences in driving performance and muscle activities before and after the intervention. [Results] Following the video game intervention, participants took significantly less time to complete the course, with less lateral deviation when turning the indoor power wheelchair. However, muscle activation in the upper limbs was not significantly affected. [Conclusion] This study demonstrates the feasibility of using joystick-controlled commercial video games to train individuals in the control of indoor power wheelchairs.

Promoting self-exploration and function through an individualized power mobility training program

PURPOSE

This case report describes the development and implementation of an intervention program that used a Power Wheelchair Trainer (Trainer) to enable an individual with severe impairments to participate in power mobility training.

CASE DESCRIPTION

The participant was an 18 year-old female with spastic quadriplegic cerebral palsy, Gross Motor Function Classification Level V. The examination included the Power Mobility Screen and the Caregiver Priorities & Child Health Index of Life with Disabilities (CPCHILD). Switches on the participant's headrest provided control of the Trainer. Intervention consisted of power mobility training in an engaging environment that was set-up to focus on specific power mobility skills.

RESULTS

Scores on the Power Mobility Screen and the CPCHILD were higher after intervention.

DISCUSSION

The outcomes of this case report appear to support the use of the Trainer, which allowed the participant to practice power mobility skills and participate in self-exploration of her environment.

Video methodologies in research: Unlocking the complexities of occupation

Background.

Video methods are used by numerous academic disciplines researching human action. Occupational therapists and scientists have primarily employed video data to enumerate subcomponents of occupational behaviour, to conduct reliability tests, and to study clinical reasoning. There is a gap in the literature using video data to explore complex dimensions of typical occupational behaviour.

Purpose.

This paper aims to encourage the use of video methodology beyond its current state in research on occupation.

Key Issues.

Drawing on recent theoretical developments in the literature and empirical illustrations from a video-based project with migrants, this paper demonstrates the potential contributions of video data to understandings of identity, the physical environment, the stream of occupations, and collective occupations. The paper also discusses the unique advantages and richness of collecting video data in comparison to interviews and traditional observations. The challenges in employing video methodologies are discussed.

Implications.

Video research offers unprecedented opportunities to study human occupation in incommensurable detail as it unfolds through sociocultural and physical environments.

A participatory approach to develop the Power Mobility Screening Tool and the Power Mobility Clinical Driving Assessment tool

The electric powered wheelchair (EPW) is an indispensable assistive device that increases participation among individuals with disabilities. However, due to lack of standardized assessment tools, developing evidence based training protocols for EPW users to improve driving skills has been a challenge. In this study, we adopt the principles of participatory research and employ qualitative methods to develop the Power Mobility Screening Tool (PMST) and Power Mobility Clinical Driving Assessment (PMCDA). Qualitative data from professional experts and expert EPW users who participated in a focus group and a discussion forum were used to establish content validity of the PMCDA and the PMST. These tools collectively could assess a user's current level of bodily function and their current EPW driving capacity. Further multicenter studies are necessary to evaluate the psychometric properties of these tests and develop EPW driving training protocols based on these assessment tools.

Practice considerations for the introduction and use of power mobility for children

AIM

The aim of the study was to support clinicians in recommending and justifying power mobility for children of different ages and abilities, and with different needs. The study comprised three distinct parts: a literature review; a Delphi consensus; and clinical practice considerations.

METHOD

A scoping review of eight electronic databases and manual searches carried out in February 2011 identified 15 themes or transferable messages among 27 articles meeting initial inclusion criteria and these formed the basis of a draft paper. Informal consensus at two international conference presentations refined and modified the paper to include 10 messages supported by 24 articles. The literature review was updated in May 2012 and a modified Delphi process sought to formalize the consensus process with an international panel of 16 expert clinicians and researchers using a priori criteria of 80% agreement.

RESULTS

Evidence from studies was classified using the American Academy of Cerebral Palsy and Developmental Medicine guidelines, with evidence from most studies being classified as either level IV or level V, apart from one study each with evidence classified as level II and level III. Expert consensus on the content and wording of nine transferable messages may raise evidence overall to level III.

INTERPRETATION

This paper suggests that power mobility may reasonably be considered as an effective and appropriate intervention for children lacking efficient, independent mobility from around 12 months of age including children who may never become competent drivers and children lacking independent mobility only in early childhood.
