International research priorities on the role of cognition in power mobility device use: In pursuit of informed clinical practices and knowledge translation

Theories, models and frameworks to understand barriers to the provision of mobility-assistive technologies: a scoping review

OBJECTIVES

There is strong evidence that mobility-assistive technologies improve occupational performance, social participation, educational and employment access and overall quality of life in people with disabilities. However, people with disabilities still face barriers in accessing mobility products and related services. This review aims to summarise and synthesise: (1) theories, models and frameworks that have been used to understand mobility-assistive technology access, (2) determinants of access and (3) gaps in knowledge.

DESIGN

A scoping review using the five-step framework by Arksey and O'Malley.

DATA SOURCES

We searched the MEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health Literature and SCOPUS databases for publications published between 2000 and 2024. We searched for articles published up to 20 March 2024.

ELIGIBILITY CRITERIA

We included English-published literature in peer-reviewed journals that reported (a) barriers to the provision of mobility-assistive technologies, (b) including at least one theory, model or framework and (c) between 2000 and 2024.

DATA EXTRACTION AND SYNTHESIS

We extracted the study characteristics, theories, models, framework usage, research recommendations, key findings on mobility-assistive technology barriers and theoretical propositions. We conduct a theoretical synthesis guided by Turner's approach.

RESULTS

We included 18 articles that used 8 theories, models and frameworks, synthesised into 9 propositions. The synthesised theory emphasises that mobility is essential for human flourishing, and that certain health conditions may impose restrictions on mobility. This impact can be alleviated by two direct determinants: (1) the provision of suitable services and (2) their comprehensive provision. Policies and costs influence these services indirectly. Environmental and personal factors also affect the use of these services. Ineffectively addressing these determinants can limit access to mobility-assistive technologies and subsequent disabilities.

CONCLUSION

Our synthetic model describes the logic of providing evidence-based mobility-assistive technologies, and we identify the determinants of access that can act as targets for future work to improve the provision of mobility-assistive technologies.

Feasibility and clinical applicability of a novel power wheelchair training approach

PURPOSE

To evaluate the feasibility and the clinical applicability of administering the COMET (cognition, occupation, mobility, evaluation and training) intervention.

MATERIALS AND METHODS

A pilot research was conducted with adults who were being considered for power wheelchair (PWC) provision, or who were recently provided a PWC, and who had been identified to benefit from a PWC training. The COMET intervention applies a goal directed, client-centred and occupation-based approach. Feasibility and applicability indicators were collected for: process, resources, management and treatment. Indicators were evaluated as "successful/unsuccessful". Clinical outcomes included the Goal Attainment Scale (GAS), the Canadian Occupational Performance Measure (COPM), the Power mobility Indoor Driving Assessment (PIDA) and the Wheelchair Skills Test (WST).

RESULTS

Four females (62.5 ± 3.5 years) with cognitive impairment participated in the study. Among the 13 indicators, 10 were successfully achieved. Indicators that did not meet the criteria for success were adherence rate, safety and treatment for the PIDA. Two adverse events were reported, with one minor injury. Participants demonstrated better than expected results on the GAS, the COPM scores and the WST. However, only two reported an improvement beyond 4% of the PIDA.

CONCLUSIONS

With few modifications, the COMET intervention and the study protocol will be feasible and applicable in clinical practice. Individuals with complex cognitive and mobility impairment demonstrated abilities to learn PWC use. Further investigation of the COMET intervention is required to evaluate its efficacy.Implications for rehabilitationA novel power wheelchair (PWC) training approach adapted to individual with complex mobility and cognitive impairments was developed: the COMET (cognition, occupation, mobility, evaluation and training) intervention.The COMET intervention applies a goal directed, client-centred and occupation-based approach.With minor modifications, the COMET intervention may be feasible and clinically applicable to train individuals with complex motor and cognitive impairments how to use a PWC.Further evaluation of the COMET intervention and lager control trialsare suggested.

Development of a new tool: progression of paediatric powered mobility- 3PM

PURPOSE

To develop a tool to assess the progression of powered mobility skills for children and determine its psychometric properties.

METHOD

A three-phase, the mixed-method design included: I) conceptualisation based on international specialists' input through a focus group or interview to generate initial items; II) tool development using a two-round Delphi survey and III) evaluation of psychometric properties from eight video recordings of children. The Progression of Paediatric Powered Mobility (3PM) was validated via Intraclass correlation coefficients (ICC) calculated from conventionally powered mobility assessments: the Powered Mobility Program, the Assessment of Learning Powered Mobility tool, and the Powered Mobility Proficiency test.

RESULTS

Content derived from 20 clinical experts led to the development of the first version consisting of 19 demographic and 61 driving skill items. Following two Delphi rounds, the final tool included 14 demographic and 41 driving skill items. Internal consistency was excellent (Cronbach alpha = 0.96) as was the inter-rater reliability (ICC = 0.96, 95% confidence interval = 0.95-0.96). Pearson correlation coefficients between the 3PM and other PM assessments demonstrated good convergent validity.

CONCLUSION

The 3PM, created through international collaboration with experts in PM, has excellent psychometric values as a valid measure that can be used reliably to assess children's powered mobility skills.Implications for rehabilitationThe 3PM reflects the three stages of powered mobility development: exploratory, operational, and functional stages.Input from clinical experts in PM mobility contributed to the identification of the key driving skills important to include in the 3PM.A reliable and valid tool can facilitate assessment and tailored intervention in paediatric powered mobility.

Lessons learned from a pediatric powered mobility lending program

PURPOSE

To evaluate children's characteristics and impact of a powered wheelchair lending program including comparisons of diagnostic sub-groups, and validation of a predictive model of powered mobility proficiency.

METHODS AND MATERIALS

This retrospective study included 172 children who participated in the ALYN powered mobility lending program from 3/2009-7/2022. Demographics and functional levels were measured via questionnaires; driving proficiency was evaluated when the wheelchair was returned, and parents and children were interviewed following their participation in the program.

RESULTS

Two diagnostic groups were identified: cerebral palsy (CP) (n = 136, median = 9.75 yrs) and other neuromuscular diseases (NMD) (n = 30, median = 5.83 yrs). They differed significantly in the age they commenced PM training, the male/female ratio, walking ability and access mode. Fifty-seven percent of the participants with CP achieved powered mobility proficiency, a rate that was significantly lower than the 73% proficiency found for the NMD group. Four significant predictors were identified: communication, manual wheelchair operation, access mode and go-stop upon request. They predicted proficiency in approximately 80% of cases. Overall feedback from the parents and children indicated that their personal and family's quality of life improved as a result of their child's ability to use a powered wheelchair.

CONCLUSIONS

A lending program provides children with opportunities to improve mobility skills in an appropriate powered wheelchair. Children who can communicate verbally, propel a manual wheelchair, use a joystick and go-stop upon request are significantly more likely to become proficient drivers; however, many who were unable to complete these tasks also improved and even became proficient drivers.

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.

Consensus for a power wheelchair training approach for people with cognitive impairments

PURPOSE

Power wheelchairs (PWCs) can enhance independent mobility. The World Health Organization recommends training PWC users. However, current PWC training approaches do not always meet the needs of PWC users with complex mobility and cognitive impairment. The aim was to co-develop an innovative approach to PWC training for individuals with complex mobility and cognitive impairments.

MATERIALS AND METHODS

A two-phase mixed method research, involving PWC users, clinicians and researchers throughout all aspects of the research, was realized. (1) Interviews and focus groups were used. (2) The Delphi method was followed to refine the PWC training approach.

RESULTS

Phase 1: Twenty-six stakeholders indicated that PWC training should consider the client as a partner, the learning environment, the proposed activities, interactions with the trainer and intervention format. Phase 2: two hundred and seven participants agreed that the PWC training should be goal directed, should be client-centred and occupation-based, should enhance client-therapist relationships and should be realized in a safe and adapted environment.

CONCLUSIONS

Stakeholders on PWC use came to agreement on key components that should be applied when training people with cognitive impairments.
