Factors Associated with Provision of Wheelchairs in Older Adults

Program evaluation and healthcare process improvement focused on complex wheelchair procurement

The operations of a specialty wheelchair (WC) seating center can influence the evaluation to delivery timeframe in days for a complex rehab technology (CRT) WC. Operations at one facility improved due to departmental process improvement (PI) project with evaluation of the delivery workflow and implementation of changes. A retrospective chart audit gathered baseline data on the evaluation to delivery timeframe in days of a CRT WC for 50 individuals prior to PI changes. Standard departmental workflow collected 745 individuals' post-PI changes. The interventions took place from March 25, 2017, to April 5, 2018, and included defining and educating stakeholders on their roles and expectations, revisions of the electronic medical record, weekly and quarterly meetings with supplier leadership, paperwork completion goals, and follow-up paperwork centralization. Mean pre- and post-intervention evaluation to delivery timeframes in days was significantly different (162.2 versus 127.4 days, p < 0.0001). Overall, a reduction in the mean evaluation to delivery timeframe in days of CRT WC by 21.5% or 34.8 days occurred. Systematic change takes time as well as the commitment of all key players. PI changes resulted in evaluation to delivery timeframe reduction for patients to receive their CRT WCs.

Predictors of type of powered mobility aid for patients: a retrospective study in a Singapore acute hospital

PURPOSE

Rehabilitation professionals prescribe patients with suitable powered mobility aids (PMAs) based on patient characteristics, e.g., age and mobility. However, there is paucity of literature examining patient characteristics associated with PMA types in Asian contexts. This research aims to study (i) characteristics of Singapore PMA users and (ii) correlations between characteristics and two PMA types - motorised wheelchairs and powered scooters. It is hypothesised that patients' age, mobility status and medical conditions have correlations with PMA types.

METHODOLOGY

A cross-sectional, retrospective study design was used to investigate characteristics of patients (age ≥ 21 years) at Tan Tock Seng Hospital Occupational Therapy Seating Clinic between 2017 and 2019. Comparisons of proportions of motorised wheelchair users versus powered scooter users based on characteristics were analysed using Chi-square test. Subsequently, statistically significant patient characteristics were selected for a multiple logistic regression.

RESULTS

Among 352 patients, 21% and 79% were prescribed motorised wheelchairs and powered scooters, respectively. Patients aged 61-90 years were twice those aged 21-60 years. Males were double of females. Patients of (i) an older age, (ii) more ambulant, (iii) independent in transfers and (iv) in activities of daily living (ADLs), were more likely powered scooter users. Conversely, patients of (i) a younger age, (ii) less ambulant, (iii) require assistance in transfers and (iv) in ADLs were more likely motorised wheelchair users. Patients' gender and caregiver status showed no statistically significant correlations with PMA types.

CONCLUSIONS

Rehabilitation professionals could consider patients' age, mobility status, transfer status and ADL status when prescribing PMA for Asian populations.

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.

Powered mobility device use in residential aged care: a retrospective audit of incidents and injuries

BACKGROUND

Powered wheelchairs and motorised mobility scooters, collectively called powered mobility devices (PMD), are highly valued by older Australians, including those living in residential care, to facilitate personal and community mobility. The number of PMDs in residential aged care is expected to grow proportionally with that of the wider community, however, there is very little literature on supporting residents to use PMDs safely. Prior to developing such supports, it is important to understand the frequency and nature of any incidents experienced by residents whilst using a PMD. The aim of this study was to determine the number and characteristics of PMD use related incidents occurring in a group of residential aged care facilities in a single year in one state in Australia including incident type, severity, assessment, or training received and outcomes on follow-up for PMD users living in residential aged care.

METHODS

Analysis of secondary data, including documentation of PMD incidents and injuries for one aged care provider group over 12 months retrospectively. Follow-up data were gathered 9-12 months post incident to review and record the outcome for each PMD user.

RESULTS

No fatalities were recorded as a direct result of PMD use and 55 incidents, including collisions, tips, and falls, were attributed to 30 residents. Examination of demographics and incident characteristics found that 67% of residents who had incurred incidents were male, 67% were over 80 years of age, 97% had multiple diagnoses and 53% had not received training to use a PMD. Results from this study were extrapolated to project that 4,453 PMD use related incidents occur every year within Australian residential aged care facilities, with the potential for outcomes such as extended recovery, fatality, litigation, or loss of income.

CONCLUSION

This is the first time that detailed incident data on PMD use in residential aged care has been reviewed in an Australian context. Illuminating both the benefits and the potential risks of PMD use emphasizes the need to develop and improve support structures to promote safe PMD use in residential aged care.

Qualitative experiences of new motorised mobility scooter users relevant to their scooter skills: a secondary analysis

OBJECTIVE

To explore the experiences of new motorised mobility scooter users from the perspectives of the assessment and training of scooter skills.

DESIGN

Descriptive secondary analysis of qualitative data.

SETTING

Community.

PARTICIPANTS

20 New users of motorised mobility scooters.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Directed qualitative analysis of up to four semi-structured interviews over the course of the first year of scooter use, to identify themes and sub-themes that could inform recommendations regarding assessment and training protocols.

RESULTS

We identified two themes. The first related to potential new content. As one example of the sub-themes, there were many excerpts that dealt with the use of skills in various combinations and permutations that were used to carry out activities during everyday life and participate in society. These excerpts suggested the importance of training skills in combination to facilitate skill transfer (or generalizability). The second theme is related to enhancements of existing content. As one example of the sub-themes, there were several excerpts that dealt with scooter security. These excerpts led to the recommendation that removing and inserting the scooter key should be added to the assessment criteria for the "turns power on and off" skill of the Wheelchair Skills Test (WST) and its questionnaire version (WST-Q).

CONCLUSIONS

The experiences of scooter users over the first year of receiving a scooter appear to be relevant to the assessment and training of scooter skills and suggest themes for further study. Clinical trial registration number: NCT02696213 IMPLICATIONS FOR REHABILITATIONThe experiences of new scooter users are highly relevant to the assessment and training of scooter skills.These experiences suggest both potential new content and enhancements of existing content to the Wheelchair Skills Program Manual.

Service delivery for complex rehabilitation technology: a scoping review

PURPOSE

Complex rehabilitation technologies (CRT) support independence for individuals with disabilities by enabling mobility for function, employment, education, and independent living. CRT service delivery is evolving, with changes to funding, provider qualifications, consumer needs, and technological advances. This scoping review investigated service delivery processes for individuals with disabilities who have a mobility impairment, while specifically identifying best practices, barriers, and unique features of health delivery policies and practices.

METHODS

We used a framework described by Colquhoun et. al. for conducting scoping reviews, a six-step process that includes: 1) identifying the research question, 2) identifying studies, 3) selecting studies 4) data charting, 5) reporting results and 6) consultation. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) was also used for reporting results of the review.

RESULTS

Common categories were identified and organised into a hierarchical structure of four categories and 16 sub-categories. The primary categories included "policy", "consumer", "service delivery", and "wheeled mobility devices". The sub-categories described funding sources, consumer and professional populations, service delivery guidelines, and types of mobility devices. Analysis indicated the data were from 21 countries and 14 combinations of funding sources, and the articles were primarily descriptive studies.

CONCLUSION

This scoping review identified evidence from various countries, health systems, and stakeholder. Currently, this process does not proactively address the needs of individuals with mobility disabilities. The scoping review provides the foundation for the development of a novel policy on the provision of CRT services and devices to address these needs.Implications for RehabilitationExamination of national and international service delivery practices in diverse clinical and funding environments indicate various challenges and opportunities for improvement.CRT consumers are negatively impacted by current service delivery practices, including long wait times, lack of specialised clinical expertise, and limited consumer education opportunities.More consistent and widespread research is needed within the CRT provision industry to grow evidence-based practice related to complex rehabilitation technology and individuals with disabilities.

Inpatient rehabilitation wheelchair management quality improvement project: Implications for patients with spinal cord injury

CONTEXT/OBJECTIVE

Evaluate hospital fleet wheelchair (WC) requests submitted by physical therapists (PT) for patients with spinal cord injury (SCI) to trial and use during inpatient rehabilitation.

DESIGN

Quality improvement project secondary analysis of delivery process and WC trials.

SETTING

Urban inpatient rehabilitation hospital.

PARTICIPANTS

Internal review of 4,371 WC requests narrowed to 750 patients with SCI.

INTERVENTIONS

PTs submitted WC requests between March 25, 2017, and September 30, 2019.

OUTCOME MEASURES

WC delivery timeframe, level of SCI, type of WC.

RESULTS

PTs requested power (28%), and manual WC bases: standard (19.1%), tilt (18.9%), ultralight rigid (18.9%), ultralight folding (13.5%), and recliner (1.6%) respectively. Patients received fleet WCs 49.9% of the time within specified urgency timeframes. A Chi-Square test showed a significant association between WC request urgency and fulfillment within established timeframes (χ² = 19.68, P < 0.001, n = 750). Broken down by urgency level: 60.0% low (n = 12), 56.2% medium (n = 244), and 39.9% high (n = 118) received their WC within established timeframes. Patients with cervical level SCI (n = 162) had the highest mean wait time of 8.28 days for power WCs. The second highest wait time was 6.29 days (SD 6.6) for manual ultralight rigid WCs (n = 34).

CONCLUSION

Inpatient fleet WC delivery is critical to patients with SCI. Variation occurs by WC type requested and by the level of injury. Gaps exist in providing appropriate WCs in facility timeframe guidelines by the level of urgency that is within 24 h for high, 3-5 days for medium, and 5-7 days for low.

Evaluation of the feasibility of an error-minimized approach to powered wheelchair skills training using shared control

BACKGROUND

Powered wheelchairs promote participation for people with mobility limitations. For older adults with cognitive impairment, existing training methods may not address learning needs, leading to difficulty with powered wheelchair skills. Error-minimized training, facilitated by shared control technology, may provide learning opportunities more suited to this population.

OBJECTIVE

The objective of this study was to evaluate the feasibility of an error-minimized approach to powered wheelchair skills training using shared control in residential care. Feasibility indicators were hypothesized a priori to be feasible for use in a definitive RCT.

METHODS

A 2 × 2 factorial RCT compared an error-minimized powered wheelchair skills training program (Co-pilot) to a control intervention at two doses (6 sessions vs. 12 sessions). Data were collected on the feasibility of study processes (e.g., recruitment), resources (e.g., participant time), management (e.g., technology reliability), and training outcomes (e.g., adverse events, clinical outcomes).

RESULTS

Twenty-five older adults with cognitive impairment participated in the study. Technical issues were encountered in 14.5% of training sessions. Participants receiving 6 sessions of training adhered better to the treatment than those receiving 12 sessions. All participants learned the skills required for PWC use with minor errors, regardless of the training method or dose. Co-pilot participants and trainers reported feelings of safety and training benefits with the use of shared control technology.

CONCLUSIONS

Individuals with mild to moderate cognitive impairment are able to learn the skills required to drive a powered wheelchair in as few as six training sessions. Further evaluation of the Co-pilot training program is required.IMPLICATIONS FOR REHABILITATIONShared control teleoperation technology may be used to augment learning in older adults with cognitive impairments.Evaluation of the feasibility of use of novel rehabilitation technologies is critical prior to engaging in large-scale clinical research.Individuals with cognitive impairment are able to learn the required skills for operation of a powered wheelchair.

Wheelchair and seating assistive technology provision: a gateway to freedom

Aim: The meaning of wheelchair and seating assistive technology and the impact inappropriate provision has on people's lives from a service user's perspective within an Irish context is highlighted. There is a dearth in evidence examining the process of wheelchair and seating provision and the interconnectedness between satisfaction, performance and participation from an equality and human rights perspective. The purpose if the study is to investigate wheelchair service users' perspectives of wheelchair and seating provision in Ireland.Method: This is a mixed-methods study with an exploratory sequential design that includes two phases. During phase one, wheelchair service users were invited to take part in qualitative in-depth semi-structured interviews, which were thematically analysed and formed part of a larger ethnographic study involving multiple stakeholders in sustainable wheelchair and seating provision strategy development. In phase two, an online Survey Monkey questionnaire was distributed to obtain a wider overview of wheelchair service provision from a wheelchair service users perspective. Data obtained from the closed questions and content analysis for open comments was analysed descriptively for this phase.Results: Eight wheelchair service users agreed to participate in the interviews and 273 responded to the online survey. Thematic analysis and questionnaire frequency and content analysis revealed the vital meaning of wheelchair and seating assistive technology provision. However, bottlenecks within the system affect daily living, with qualitative data highlighting the obstruction to experiences of independent living from initial appointment to wheelchair breakdowns during daily life.Conclusion: Appropriate wheelchair and seating assistive technology provision is a basic human right, supported by the essential and embodied nature of the wheelchair as demonstrated through the wheelchair service users' perspective throughout this study. These findings highlight the impact of ad-hoc services on individual freedoms and how the overall pace of the system affects a person's ability to organise their time as an equal member of the community across the lifespan. A national review of wheelchair and seating assistive technology provision services is called for, giving consideration to access to services, assessment and delivery, follow up and management, education and training.IMPLICATIONS FOR REHABILITATIONWheelchair and seating assistive technology provision as a basic human right is misunderstood.Appropriate wheelchair and seating assistive technology provision should be provided to meet this primary need as a pre-requisite for survival.Every aspect of the wheelchair and seating provision process impacts on occupational performance, equality of opportunity and community mobility. Wheelchair and seating assistive technology professionals and providers have a responsibility to review their practice and service provision systems.

Influence of Cognitive Functioning on Powered Mobility Device Use: Protocol for a Systematic Review

Background

Power mobility devices (PMD) are critical to achieving independent mobility and social participation for many individuals who have trouble walking. Provision of PMDs is complex, with cognitive functioning expressed by clinicians as a major concern. Even if PMD use can be predicted by the level of cognitive functioning, outcome tools used to assess readiness do not consider how cognitive functioning may affect PMD use.

Objective

The specific aims of this review are to identify existing assessments used to assess cognitive functioning and PMD use, classify cognitive functions that are identified within existing assessments related to PMD use, and explore the relationships between cognitive functioning (ie, executive functions and attention) and PMD use.

Methods

A systematic review will be conducted using the electronic databases MEDLINE (Ovid), CINAHL, Embase, PsycINFO (Ovid), and Web of Science based on the concepts of PMD performance and capacity, and cognitive functioning. To be included, studies must have: a sample of PMD users (inclusive of age and diagnoses), an assessment of cognitive functioning, and an assessment of PMD capacity or performance. The International Classification of Functioning, Disability and Health will be used to classify cognitive functions. Study quality will be assessed using the Mixed Methods Appraisal Tool. Qualitative and quantitative studies will be analyzed in a complementary manner depending on their designs; a result-based convergent synthesis design will be applied.

Results

This proposed systematic review protocol has been registered in PROSPERO (CRD42019118957). It was funded by the Quebec Rehabilitation Research Network and approved on February 2019.

Conclusions

Results will inform the development of a PMD driving program that aims to enhance cognition. The results of this study will enhance understanding of the influence of cognitive functioning on PMD use and will support the clinical practice in choosing appropriate evaluative tools.

“A Chance to Try”: Exploring the Clinical Utility of Shared-Control Teleoperation for Powered Wheelchair Assessment and Training

Importance: Powered wheelchairs provide independence for people with mobility impairments; however, current training practices may not meet the needs of those with cognitive impairments. Shared-control teleoperation may have utility in a clinical setting when developing training suited to this population.

Objective: To explore the clinical utility of a shared-control teleoperation device for powered wheelchair assessment and training.

Design: In this qualitative study, we used two sequential semistructured interviews conducted a minimum of 2 wk apart. Thematic analyses were used with member checking, reflexive journaling, and triangulation of researchers to establish trustworthiness of the data.

Setting: Rehabilitation center and residential care and community settings.

Participants: Using purposive sampling, we recruited occupational therapists and physical therapists who were mostly female and who had a range of practice experience.

Results: Fifteen participants were interviewed, and two primary themes were identified: (1) “A big enabler” described how shared control provides opportunities to train people who may otherwise be denied powered mobility, and (2) “changing the learner experience” described how shared control may promote success in skill development through an alternative learning experience.

Conclusions and Relevance: Shared-control technology may have the potential to broaden the scope of therapeutic intervention by reducing risk to the driver and others in the environment and by facilitating alternative training approaches.

What This Article Adds: Technological advances that allow more control over a powered wheelchair by a clinician, known as shared control, may provide learning opportunities for people who are otherwise denied access to powered mobility. Shared control may also allow the use of new instructional techniques, increase safety in the training process, and reduce anxiety associated with learning.

Feasibility RCT protocol evaluating a powered-wheelchair training program for older adults

Background.

Powered-wheelchair use improves participation for people with mobility limitations; however, many individuals do not receive powered-wheelchair skills training that meets their learning needs.

Purpose.

The aim of this work is to evaluate the feasibility of a powered-wheelchair training program for older adults with cognitive impairment, using errorless learning strategies facilitated by shared control technology.

Method.

A feasibility 2 × 2 factorial randomized controlled trial will recruit 32 older adults in residential care with mild to moderate cognitive impairment who are new powered-wheelchair use. The intervention consists of six or 12 training sessions, facilitated by shared control technology, using errorless learning techniques. Control participants will receive six or 12 training sessions using trial-and-error methods. Feasibility and clinical outcomes data (primary outcome: powered-wheelchair skills) will be collected.

Implications.

Errorless learning facilitated by shared control technology may be an alternative to meet the powered-wheelchair learning needs of older adults with cognitive impairments.

Comparison of seating, powered characteristics and functions and costs of electrically powered wheelchairs in a general population of users

PURPOSE

To profile and compare the seating and powered characteristics and functions of electrically powered wheelchairs (EPWs) in a general user population including equipment costs.

METHOD

Case notes of adult EPW users of a regional NHS service were reviewed retrospectively. Seating equipment complexity and type were categorized using the Edinburgh classification. Powered characteristics and functions, including control device type, were recorded.

RESULTS

482 cases were included; 53.9% female; mean duration EPW use 8.1 years (SD 7.4); rear wheel drive 88.0%; hand joystick 94.8%. Seating complexity: low 73.2%, medium 18.0%, high 8.7%. Most prevalent diagnoses: multiple sclerosis (MS) 25.3%, cerebral palsy (CP) 18.7%, muscular dystrophy (8.5%). Compared to CP users, MS users were significantly older at first use, less experienced, more likely to have mid-wheel drive and less complex seating. Additional costs for muscular dystrophy and spinal cord injury users were 3-4 times stroke users.

CONCLUSIONS

This is the first large study of a general EPW user population using a seating classification. Significant differences were found between diagnostic groups; nevertheless, there was also high diversity within each group. The differences in provision and the equipment costs across diagnostic groups can be used to improve service planning. Implications for Rehabilitation At a service planning level, knowledge of a population's diagnostic group and age distribution can be used to inform decisions about the number of required EPWs and equipment costs. At a user level, purchasing decisions about powered characteristics and functions of EPWs and specialised seating equipment need to be taken on a case by case basis because of the diversity of users' needs within diagnostic groups. The additional equipment costs for SCI and MD users are several times those of stroke users and add between 60 and 70% of the cost of basic provision.

Factors Associated With Recommendations for Assistive Technology Devices for Persons With Mobility Limitations Using Workplace Accommodation Services

The objective of this study was to identify the interactions between impairment-related and work-related factors associated with recommendations for specific assistive technology devices (ATDs) for persons with mobility limitations who used workplace accommodation (WA) services. A retrospective and secondary data analysis was conducted on 132 WA service users with mobility limitations in Taipei City from 2008 to 2012 using chi-square automatic interaction detector (CHAID). The CHAID analyses revealed interactions between impairment-related factors (difficulty walking and upper extremity pain) and work-related factors (frequent moving around outdoors), which were significantly associated with the recommendation of powered wheelchairs ( p < .05). Interactions between the impairment-related factor (difficulty walking) and the work-related factor (frequent sitting for long periods of time) were associated with the recommendation of ergonomic chairs ( p < .001) for persons with mobility limitations. By identifying the interactions between impairment-related and work-related factors in recommending workplace ATDs for persons with mobility limitations, this study provides evidence-based ATDs recommendations for persons with mobility limitations.

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.

Evidence-Based Strategies for Preserving Mobility for Elderly and Aging Manual Wheelchair Users

Elderly and aging manual wheelchair (MWC) users have increased risk for accelerated loss of function and mobility that greatly limits independence and affects quality of life. This review paper addresses important issues for preserving function and mobility for elderly and aging individuals who use a MWC by presenting the current available evidence and recommendations. These include recommendations for maximizing function, by decreasing pain, improving the ability to self-propel, and prolonging mobility and endurance through ergonomics, individualized wheelchair selection and configuration, and adaptations for increasing the capacity to handle the daily mobility demands through training, strengthening, and exercise. Each recommendation is supported by current research in each relevant area.

What factors are associated with the provision of assistive technologies: the Bogotá D.C. case

AIM

To examine what demographics and clinical factors are associated with the provision of assistive technology (AT) devices in a low-income country.

METHOD

Retrospective cross-sectional exploratory study design including 15 of the 20 localities across Bogotá D.C., Colombia, a city with 6,776,009 inhabitants.

RESULTS

The type of AT device provided was significantly dependent (p < 0.001) on the client's diagnosis, impairment, age, and socio-economic strata, whether the client has a care giver, the geographical zone in which the client lives, the year of the AT provision, and the total number of AT delivered. In contrast, the client's gender (p > 0.05) and the client's affiliated type of healthcare service had no effect. In addition to that, the client's age, the client's socio-economic strata, the number of AT devices provided to the client, and the diagnostic type were the factors with the strongest level of association with the type of AT device provided.

CONCLUSIONS

Our research showed that the provision of AT in Bogotá D.C. prioritizes both people who are at the highest levels of vulnerability, and as many people as possible with the budget. That is, the low socio-economic strata, younger and older people, and the provision of at least one AT device.

IMPLICATIONS FOR REHABILITATION

Provision of AT is intended for equal opportunities for the social participation of people with a disability. Also, people with disabilities have the right to access AT regardless of the type of limitation, gender, race, age or region where they live. Research regarding AT in developing countries is scarce; thus, there is a need to conduct studies in such contexts. This study provides scientific evidence to support the development of models, approaches and strategies of AT provision in low-income countries where resources for rehabilitation are scarce.

Power mobility with collision avoidance for older adults: user, caregiver, and prescriber perspectives

Collision avoidance technology has the capacity to facilitate safer mobility among older power mobility users with physical, sensory, and cognitive impairments, thus enabling independence for more users. Little is known about consumers' perceptions of collision avoidance. This article draws on interviews (29 users, 5 caregivers, and 10 prescribers) to examine views on design and utilization of this technology. Data analysis identified three themes: "useful situations or contexts," "technology design issues and real-life application," and "appropriateness of collision avoidance technology for a variety of users." Findings support ongoing development of collision avoidance for older adult users. The majority of participants supported the technology and felt that it might benefit current users and users with visual impairments, but might be unsuitable for people with significant cognitive impairments. Some participants voiced concerns regarding the risk for injury with power mobility use and some identified situations where collision avoidance might be beneficial (driving backward, avoiding dynamic obstacles, negotiating outdoor barriers, and learning power mobility use). Design issues include the need for context awareness, reliability, and user interface specifications. User desire to maintain driving autonomy supports development of collaboratively controlled systems. This research lays the groundwork for future development by illustrating consumer requirements for this technology.

Recipients of electric-powered indoor/outdoor wheelchairs provided by a national health service: a cross-sectional study

OBJECTIVE

To describe the characteristics across all ages of powered wheelchair users and the assistive technology prescribed by a regional specialist wheelchair service.

DESIGN

Cross-sectional study.

SETTING

Regional wheelchair service.

PARTICIPANTS

Electric-powered indoor/outdoor wheelchair (EPIOC) users (N=544) with 262 boys and men (mean age ± SD, 41.7±20.7y; range, 8-82y) and 282 girls and women (mean age ± SD, 47.2±19.7y; range, 7-92y).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Demographic, clinical/diagnostic details of EPIOC recipients, including pain, (kypho)scoliosis, and ventilators. Technical features, including specialized (adaptive) seating, tilt in space, and modified control systems. Factors were related to age groups: 1 (0-15y), 2 (16-24y), 3 (25-54y), 4 (55-74y), and 5 (≥75y).

RESULTS

Neurologic/neuromuscular conditions predominated (81%) with cerebral palsy (18.9%) and multiple sclerosis (16.4%). Conditions presenting at birth or during childhood constituted 39%. Of the participants, 99 had problematic pain, 83 had (kypho)scoliosis, and 11 used ventilators. Specialized (adaptive) seating was provided to 169 users (31%); most had cerebral palsy or muscular dystrophy. Tilt in space was used by 258 (53%) participants. Younger people were more likely to receive tilt in space than older ones. Only 92 had specialized (adaptive) seating and tilt in space (mean age ± SD, 29±17.8y; range, 8-72y). Of the participants, 52 used modified control systems.

CONCLUSIONS

The diversity of EPIOC users across age and diagnostic groups is shown. Their complex interrelations with these technical features of EPIOC prescriptions are explored. Younger users were more complex because of age-related changes. This study provides outcomes of the EPIOC prescription for this heterogeneous group of very severely disabled people.
