Development of the Standardized Navigation Of Winter Mobility & Accessibility Network (SNOWMAN) course.

Introduction: Manual wheelchairs (MWC) users have limited mobility during winter months as they encounter many environmental barriers that restrict their community participation. This paper outlines the creation and standardization of an outdoor environment designed to simulate the real-life conditions and obstacles experienced by MWC users in winter. Methods and results: This study consisted of four phases. In Phase 1, researchers used a qualitative ethnographic approach to document the specific challenges and adaptive strategies used by MWC users in winter conditions. In Phase 2, key informants with expertise in MWC winter mobility were invited to co-design the Standardized Navigation Of Winter Mobility & Accessibility Network (SNOWMAN) course. Participants reviewed draft design solutions and offered their input and suggestions to expand upon the initial design. A second co-design workshop included additional key informants, including service providers, policymakers, and professionals with expertise in landscape architecture and engineering, to validate the design solution. The workshops resulted in a detailed illustration of the SNOWMAN course, including five sections: platforms with side slopes, a miniature ice rink, curbs and curb cuts, a path with uneven winter surfaces, and modular ramps at various slopes. Phases 3 and 4 marked the conclusion of the study and involved fabrication of the SNOWMAN course and establishment of a standardized protocol for course setup and maintenance. Discussion: The project aimed to offer several additional potential benefits, supported by the various stakeholders across the study phases, that extend beyond creation of a controlled and safe environment for wheelchair users to develop their winter mobility skills. Practicing wheelchair skills in this area may assist wheelchair users in gaining confidence which may ultimately translate to increased participation in the community.

Changes in functioning and health during the first 6-months of the COVID-19 pandemic among individuals with a spinal cord injury.

STUDY DESIGN: Single-cohort longitudinal survey design. OBJECTIVES: To identify what ongoing impact the COVID-19 pandemic has on functioning and health in individuals with SCI. Using the ICF model as a guide, outcome measures were chosen to explore potential constructs and aspects of health and functioning which may have been affected by regulations. SETTING: Online, Canada. METHODS: Participants provided demographic and clinical characteristics at baseline. They completed standardized online measures at three time points, each roughly one month apart (June, July, and August of 2020). The measures assessed mental health, resilience, boredom, social support, technology use, life space, and participation. Repeated measures ANOVAs were used to identify longitudinal changes for each measure. RESULTS: We collected data from 21 participants with SCI (mean age 54 years, 12 male). We found a large effect size for participation (η2 = 0.20), which increased over time. We also found medium effect sizes in both anxiety (η2 = 0.12) and social network usage (η2 = 0.12). Anxiety decreased over time and social networking usage fluctuated slightly but with an increase from time point one to time point two. CONCLUSION: The results indicate that individuals with spinal cord injury appear to be staying relatively stable during the pandemic with improvements in a few key aspects, such as potentially increased participation and decreased anxiety. The results also suggest that it is important to continue fostering ways for individuals with spinal cord injury to stay connected, engaged, and informed.

Accessible exercise for wheelchair users: comparing the usability of two adapted exercise machines.

INTRODUCTION: Exercise is an important occupation for wheelchair users. Limited access to adapted aerobic exercise equipment in the community and lack of knowledge on how to exercise are barriers to exercise participation among wheelchair users. To address these barriers, the adapted rower (aROW) and adapted skier (aSKI) exercise machines and educational materials were created. PURPOSE: 1) To compare wheelchair users' perspectives of the effectiveness and usability of the aROW and aSKI. 2) To explore perceptions of educational materials to support use of the machines. MATERIALS AND METHODS: A sequential, mixed-methods study design was used. Six wheelchair users trialled the machines, and completed an interview and two usability questionnaires. Qualitative data were analysed using thematic and conventional content analysis. Usability scores of both machines were compared using the Wilcoxon Signed Ranks Test. RESULTS: Data show high usability of the aROW and aSKI. More set up challenges were reported for the aROW than the aSKI. Participants perceived both machines provided effective cardiovascular workouts, and each met their exercise goals differently. Participants preferred the instructional videos over instructional sheets and provided suggestions for improving both. The Wilcoxon Signed Ranks Test showed no statistically significant difference in usability between the aROW and aSKI. CONCLUSION: Implementing the aROW and aSKI in the community may address some equity issues that wheelchair users face by providing more aerobic exercise options. Results will inform educational material revisions to support use of the machines.IMPLICATIONS FOR REHABILITATIONThe adapted rower (aROW) and adapted skier (aSKI) were perceived as highly usable, suggesting provision of more adapted aerobic exercise options, like the aROW and aSKI, may address some exercise-related equity issues wheelchair users experience.Wheelchair users may consider multiple factors when choosing adapted exercise equipment, highlighting the importance of providing multiple options for adapted aerobic exercise equipment to facilitate agency in choice of exercise.

Quality of Physical Activity Participation Among Adults with Disabilities Through Pandemic Restriction.

Background. Physical activity (PA) is essential for maintaining well-being in adults with disabilities. This population experienced reduced PA during the COVID-19 pandemic; yet, the impact on quality of PA participation remains unclear. Purpose. This secondary analysis explored how pandemic restrictions impacted six experiential dimensions of quality of PA participation among adults with disabilities. Methods. An exploratory sequential mixed-methods design, including semi-structured interviews (n = 10) and self-reported surveys (n = 61), was conducted in May-2020 and February-2021. Quality of PA participation was measured using the Measure of Experiential Aspects of Participation (MeEAP). Participants included community-dwelling adults over 19 years of age (mean 59.2 ± 14.0 years) living with stroke, spinal cord injury, or other physical disabilities. Findings. Directed content analysis identified three themes related to adjusting PA participation for restrictions, motivation barriers, and valuing social support. These themes highlighted five factors, such as resilience, as potential quantitative predictors of quality of PA participation. While paired correlations with MeEAP scores were observed, these factors were not statistically predictive in multiple regression analysis (adjusted R2 = -0.14, F(10,50) = 0.92, p = .53). Implications. The interplay between Meaning, Autonomy, Engagement, and Belongingness dimensions of quality of PA participation was complex, with an emphasized role for mental health, in adults with disabilities.

Perceptions of power-assist devices: interviews with manual wheelchair users.

PURPOSE: The study had three main objectives. (1) To investigate the perceived impact of power-assist devices (PADs) on manual wheelchair (MWC) user mobility. (2) To compare perceptions about different types of PADs. (3) To identify preferred features and design characteristics of PADs. METHODS: Semi-structured interviews were conducted with community-dwelling MWC users aged 31 years and older, with at least 2.5 years of experience using an MWC independently (n = 16). Data were thematically analysed using an inductive approach. RESULTS: Two main themes related to participants' perceptions about the effects of PAD use were identified: (1) "Expanding my world", which illustrated the perceived benefits of using PADs (e.g., gaining a sense of autonomy and access to new environments, maintaining physical health) and (2) "Falling short", which described challenges with PADs (e.g., safety, reliability and portability issues). Participants also identified strengths and limitations of different types of PADs that were mainly related to specific user-device and device-environment interactions as well as various functional characteristics. Moreover, participants outlined their priorities for future PAD design, including improving controllability, customizability and affordability of these devices. CONCLUSIONS: Participants' perceptions about PADs varied across different types of devices and in different contexts. However, PADs were generally perceived as enhancing the capabilities of MWCs. Our findings provide insight into the factors that can be considered when selecting a PAD and can inform the development of future PADs that are better equipped to overcome challenges that MWC users frequently encounter.Implications for RehabilitationPower-assist devices (PADs) for manual wheelchairs (MWCs) have the potential to improve the mobility, community participation and well-being of users.Some of the existing PADs have safety and reliability issues that affect their performance and limit their use by MWC users.The three types of PADs (front-mounted attachments, rear-mounted attachments, powered wheels) offer different types of assistance that can benefit users with various capabilities.

Evaluation of two power assist systems for manual wheelchairs for usability, performance and mobility: a pilot study.

BACKGROUND: Power-assist devices for manual wheelchairs offer benefits, including increased community participation. Several power-assist devices are commercially available, but research on benefits and limitations of devices is limited. OBJECTIVE: To compare the usability, performance, and mobility of two power-assist device systems for manual wheelchairs in indoor and outdoor environments. METHODS: This mixed methods pilot study included 11 volunteers with limited wheelchair experience. Participants tested two different power-assist device configurations: (1) the Batec® and (2) the SmartDrive® + Freewheel®. Indoor & outdoor obstacle courses contained relevant skills from the Wheelchair Skills Test, Power Mobility Community Driving Assessment, and Power Mobility Indoor Driving Assessment. The NASA Task Load Index and System Usability Scale assessed participants' perceptions of cognitive demand and usability. A semi-structured interview was conducted to explore participants' experiences. RESULTS: Substantial differences were found in the NASA Task Load Index, and System Usability Scale scores. Participant interviews and researcher observations revealed each device performed better on some obstacle course elements. Qualitative findings showed a general preference for using the Batec® for long trips outside and off-road terrains, primarily due to the Batec's® perceived better speed control, maximum speed, and simpler braking system. Conversely, the SmartDrive® + Freewheel® was deemed most useful indoors and in tight spaces; due to a smaller wheelchair footprint, better turning radius, and increased device portability. CONCLUSION: Further studies are required to understand the usability, performance, and mobility of power-assist devices. Moving forward, these findings will inform end users and occupational therapists when procuring manual wheelchair power-assist devices.Implications for rehabilitationPower-assist devices (PADs) for manual wheelchairs increase the potential for community participation.Qualitative findings showed a general preference for using the Batec® for long trips outside and for off-road terrains, primarily due to the Batec's® perceived better speed control, maximum speed, and simpler braking system.The SmartDrive® + Freewheel® was deemed most useful indoors and in tight spaces; due to a smaller wheelchair footprint, better turning radius, and increased device portability.Increasing knowledge and research about PADs will support development of alternative options for manual or power wheelchairs users. PADs may allow manual wheelchair users (MWC) to delay moving to a power wheelchair (PWC), potentially reducing the perceived stigma associated with transitioning to a power wheelchair and impacting health outcomes.

Perception of autonomy among people who use wheeled mobility assistive devices: dependence on environment and contextual factors.

PURPOSE: To evaluate and compare the perceived autonomy of people using wheeled mobility assistive devices (WMADs) in five community-based environments. To evaluate how personal, environmental, and assistive device-related factors impact the perceived autonomy of WMAD users. METHOD: A study-specific questionnaire was used to evaluate perceived satisfaction of WMAD users with their autonomy in five environments: the Home Environment, Buildings Outside of the Home Environment, Outdoor Built Environment, Outdoor Natural Environment, and Transportation. For each environment, participants rated their satisfaction with autonomy about 15 personal, environmental, and assistive device-related factors. Qualitative perceptions were also collected with open-ended questions. RESULTS: Participants included 123 full- and part-time community-dwelling WMAD users. Participants' overall satisfaction with autonomy in the Outdoor Natural Environment was statistically significantly lower compared to the other four environments (p < 0.05). In all environments, the top factor respondents were most satisfied with was WMAD ease of use. Their least satisfaction was when negotiating stairs, curbs, or obstacles in the Home, Buildings Outside of the Home, and the Outdoor Built Environments. In the Outdoor Natural Environment, the most dissatisfaction was with manoeuvring on different terrains. Responses to open-ended questions supported the quantitative findings and highlighted the effects of various factors on autonomy (e.g., subject-environment familiarity). CONCLUSIONS: WMAD users reported the greatest restriction to their autonomy in outdoor environments. Different context-specific factors were found to impact autonomy in different environments. Understanding how environment-specific contextual factors contribute to overall perception of autonomy may inform the development of future strategies to overcome identified limitations and challenges.Implications for RehabilitationWheeled mobility assistive device (WMAD) users experienced the highest autonomy in their home environments, specifically, when having access to home modification services.WMAD users had the lowest autonomy in the outdoor natural environment, with manoeuvrability on different terrains being the main predictor of the overall satisfaction with autonomy in this environment.Environment-specific contextual factors with significant impacts on perceived autonomy were identified that can inform the design and development of future WMADs (e.g., distance travelled, safety).

Design of an mHealth application for winter mobility for mobility device users.

BACKGROUND: There is limited evidence on the strategies, resources, and tools shown to improve winter mobility and community participation. OBJECTIVE: This paper describes a multifaceted approach taken to develop an mHealth application that provides information, resources, and strategies to facilitate winter mobility for mobility device users, service providers, community organisations, and researchers. METHODS: The study was conducted in three phases: (1) A scoping review of peer-reviewed and grey literature was completed to identify literature that reported on tools, strategies, resources, and recommendations used to promote winter mobility; (2) Online asynchronous focus groups were conducted to identify the type of content that mobility device users wanted to include in the web-based application; and (3) A prototype mHealth application was developed based on the findings from the previous phases. Using a rapid prototyping process that included stakeholder review through an online survey, four cycles of application design and development were undertaken. RESULTS: The scoping review identified 23 peer-reviewed studies and limited grey literature on winter mobility strategies, resources and recommendations. Twenty-four participants from across Canada engaged in one of five focus groups. Focus group analysis led to the development of the content categories for the mHealth application. The initial prototype application developed was reviewed by; 27 mobility device users, 16 health care providers, and seven consumer organisation representatives identified areas of strength and further refinement in regard to application design. CONCLUSIONS: The approach used in this study provided a method to develop an application based on the ideas, needs, and interests of a variety of stakeholders. Once fully developed, the application has the potential to fill the gaps related to the lack of a unified collection of winter mobility strategies and resources, and open the dialogue on methods to improve winter participation among mobility device users.IMPLICATIONS FOR REHABILITATIONDespite winter conditions being a common challenge among mobility device users, there is an absence of an organised approach towards helping individuals manage their winter mobility needs.As the development and usage of mHealth applications continues to increase, it is valuable to use methods of designing applications based on the ideas, needs, and interests of a variety of stakeholders.Development of a framework for collating information on winter mobility strategies and resources is the first step towards launching an mHealth application.

Providing Accessible ReCreation Outdoors-User-Driven Research on Standards: Protocol for Mobile and Web-Based Interviews for Winter Assessments.

BACKGROUND: Although there have been recent efforts to improve access to Canadian national parks, many remain not fully accessible to people with disabilities. Winter conditions, in particular, present challenges that limit their participation in outdoor activities. OBJECTIVE: This study aimed to develop a novel method to assess park access during winter, which will inform recommendations for national park standards to meet the needs of all park visitors (regardless of ability) during winter conditions. METHODS: A larger participatory mixed methods research project exploring park access was adapted. A 3-phase approach has already been proposed to achieve the study objectives. In the first phase, a scoping review of the existing accessibility standards will be conducted. In the second phase, objective audits of trails and features in 6 parks, 3 in western Canada and 3 in eastern Canada, will be conducted, as well as mobile interviews with 24 various participants in each region regarding their experiences of and recommendations for improving the park's accessibility. In the final phase, a Delphi participatory consensus development process will be used, based on the data gathered in the first 2 phases, to prioritize recommendations for standards. This paper will focus on the second phase of the study, specifically on whether the in-person winter mobile interviews (ie, walking and wheeling interviews) with people who have a wide range of disabilities while visiting 3 parks in 2 provinces were modified. Changes were made to accommodate the extreme winter weather conditions in Quebec while using safe and informative data collection methods. RESULTS: In Quebec, one park, where winter conditions are safer, has been assessed in person (n=4). Web-based interviews were used to facilitate the assessment of other winter and summer conditions in two other parks (n=8). Winter and web-based interviews were completed in April 2022. Data are currently being collected and analyzed, and results will be completed by December 2022. CONCLUSIONS: We expect that adapting the protocol to gather further information on winter conditions and access to parks will provide high-quality and rich data to better inform park access standards. This participatory mixed methods research will inform the development of park standards that consider the accessibility needs of all people.

The COVID-19 Pandemic Related Lived Experiences of Individuals With a Spinal Cord Injury/Disease.

Introduction: COVID-19 related restrictions and recommendations have impacted everyone. Those living with a disability, such as individuals with a spinal cord injury (SCI), may have had pandemic related changes made yet more challenging by societal failures to accommodate their mobility, physical abilities, and health care needs. To better understand participants experiences we drew upon Heidegger's phenomenology and the mobilities paradigm. The objective of this study was to explore COVID-19 pandemic related lived-experiences of individuals with an SCI. Materials and Methods: This study used an interpretive phenomenological methodology. Semi-structured interviews were the primary means of data collection. These were conducting in May and June of 2020, roughly 2-3 months into the pandemic. Transcript data were analyzed using a phenomenological methodology. Results: We interviewed 22 participants with SCI, the mean age was 54 years, and nine were females. We identified three themes: (1) Experiencing changes to mobility and daily life described how new rules had impacted everyday life and usual routines, particularly in regard to mobility. (2) Struggling with new challenges explored some of the negative experiences of the pandemic. (3) Being resilient in the face of a new normal conveyed the resilience participants exhibited despite challenges. Conclusion: Although our findings indicate some positive changes and highlight the strengths that many individuals with SCI have, they also accentuate issues with ableism within the medical system. Certain changes were made primarily because people without disabilities needed them, and several COVID-19 changes were made without consulting individuals with disabilities. With physical movement restricted, our findings emphasize the importance of the movement of information and a need for increased dialogue with people in the SCI community about their ongoing pandemic related needs.

Standing power wheelchairs and their use by children and youth with mobility limitations: an interrupted time series.

: Standing power wheelchairs (PWSDs) expand positioning and mobility options for individuals with motor impairments. Although more available, little is known about how PWSDs are used in everyday life. PURPOSE: to describe children's use of PWSDs in the first three months post-wheelchair delivery and the impacts on satisfaction with participation in daily life. MATERIALS AND METHODS: An interrupted time series of purposefully sampled children aged 5-18 years who were receiving a PWSD. The Wheelchair Outcome Measure for Young People (WhOM-YP) documented satisfaction with patient-reported meaningful participation outcomes. Data loggers objectively measured wheelchair mobility outcomes including distance travelled, bouts of mobility, and duration. Data were measured over two sessions pre-wheelchair-delivery and at one week, one month and three months post-wheelchair-delivery. RESULTS: Six children aged 7-18 years participated, four diagnosed with cerebral palsy, two with spina bifida. Analyses of individual data illustrated positive change in overall WhOM-YP satisfaction scores after PWSD provision though change varied across time, as did, distance, bouts of mobility and duration of use. Participants identified 14 in-home and 16 out-of-home unique participation outcomes, although several commonalities existed. CONCLUSION: PWSDs hold promise for increasing children's satisfaction with participation in daily life, in addition to possibly increasing mobility outcomes. IMPLICATIONS FOR REHABILITATIONFor children with mobility limitations, PWSDs may promote participation in daily life and increased mobility.Data logger technology provides valuable information about children's PWSD use and how this varies over time.Benefits and challenges exist with implementing PWSD and data logger technologies.When implementing PWSD use, it is critical to consider context, training and support needs of clients and caregivers.

Providing Accessible Recreation Outdoors-User-Driven Research on Standards (PARCOURS): Protocol for a Multiphase Study.

BACKGROUND: Canada's national parks are world-renowned. However, despite recent attempts to improve access, many are not accessible to people with disabilities. With the advent of provincial and federal legislation, standards are being developed to assist with the design and management of parks. OBJECTIVE: The overarching objective of this study is to inform accessibility standards for federal parks that meet the needs of all park visitors, regardless of ability. The specific objectives of this study are to identify park accessibility standards that exist internationally, identify the accessibility challenges that people with disabilities face in park environments, and prioritize and recommend accessibility standards for national parks. METHODS: A 3-phase approach will be used to achieve the study objectives. In the first phase, a scoping review of the existing accessibility standards will be conducted. The second phase will include objective audits of trails and features in 6 parks, 3 in western Canada and 3 in eastern Canada, as well as mobile interviews with 24 diverse participants in each region regarding their experiences of and recommendations for improving the park's accessibility. In the final phase, a Delphi participatory consensus development process will be used, based on the data gathered in the first 2 phases, to prioritize recommendations for standards. RESULTS: We expect to find gaps in existing standards that do not account for the diverse range of accessibility requirements that people with disabilities have for visiting parks. We also expect to find that existing standards, on their own, may not be enough to ensure equitable access to all the experiences and amenities that parks have to offer. Development of subsequent guidelines and best practices may be necessary to address complex scenarios for which standards may not be the best approach to ensuring accessibility. CONCLUSIONS: The participatory and mixed methods approaches used in this study will provide rich insights for developing accessible park standards that consider the diverse needs of people with disabilities. The findings will also support the development or enhancement of park standards at all levels of government. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/33611.

Acute physiological comparison of sub-maximal exercise on a novel adapted rowing machine and arm crank ergometry in people with a spinal cord injury.

STUDY DESIGN: Non-randomized crossover trial. OBJECTIVES: The objective of this study was to assess the oxygen uptake during exercise using the Adapted ROWing machine (AROW) compared to the more commonly used Arm Crank Ergometry (ACE) for people with spinal cord injury/disease (SCI/D) with or without trunk stability. SETTING: Canada, Vancouver. METHODS: Participants were from a convenience sample of 14 adults with SCI/D (age 21-63 y) which include those with lumbar to low cervical impairments currently exercising at least once per week using cardiovascular exercise equipment at our Physical Activity Research Centre. The interventions were non-randomized steady-state exercise bouts at self-selected low and moderate workloads on the AROW and ACE for 5 min each. Our primary outcomes were the rate of oxygen consumption (mL/kg/min) and the Borg 0-10 Rating Scale of Perceived Exertion (RPE). RESULTS: A repeated measures two-way ANOVA (p < 0.05) indicated that exercising on the AROW resulted significantly greater oxygen consumption and perceived exertion than ACE at similar sub-maximal workloads which may be explained by the differences in efficiency between the devices (Partial eta squared = 0.84, F stat = 48.25; Partial eta squared = 0.86, F stat = 53.54). CONCLUSIONS: We have demonstrated that this form of upper extremity exercise had a greater RPE and VO2 on the ACE at a given workload. Thus, the AROW could provide a functional upper extremity workout that can be used for daily exercise for those with varying levels of SCI.

Perception of autonomy among people who use wheeled mobility assistive devices: Dependence on the type of wheeled assistive technology.

We evaluated perceived autonomy among users of different types of wheeled mobility assistive devices (WMADs) across five environments and identified the effect on user autonomy due to specific device characteristics. A study-specific questionnaire was used to assess satisfaction with autonomy of WMAD users in the Home, Buildings Outside of the Home, Outdoor Built, Outdoor Natural Environment, and Transportation. For each environment, 15 contextual factors were rated for their impact on participants' autonomy. Our results revealed that manual wheelchair with add-on (MWC+AO) users had higher overall satisfaction with their autonomy compared to other WMAD users. MWC+AO users reported higher satisfaction with autonomy due to their health conditions compared to other WMAD users across all environments. In Outdoor Natural Environments, MWC+AO users had the highest satisfaction with autonomy across all factors except for negotiating hills. When performing activities in Buildings, MWC users with and without add-ons reported higher satisfaction for all factors compared to power wheelchair users, except for maneuverability on different surfaces. Satisfaction with autonomy regarding contextual factors varied among WMAD users, however, MWC+AO(s) appeared to provide a more balanced sense of autonomy across most factors and environments. More in-depth investigations are required to evaluate impacts of add-on use on autonomy.

Exploring exercise participation and the usability of the adaptive rower and arm crank ergometer through wheelchair users' perspectives.

PURPOSE: Arm crank ergometry and adaptive rowing are existing exercise options for wheelchairs users, but not commonly available. This study was conducted to explore exercise participation of wheelchair users, as well as the usability of the adaptive rowing ergometer (aROW) and arm crank ergometer (ACE). METHODS: This mixed-methods study used a concurrent triangulation design. Following completion of both exercise sessions (5 min each), participants (n = 14) with spinal cord injury/disease (SCI/D) completed the System Usability Scale (SUS), and a semi-structured interview. Participants were asked about the use of both exercise modalities, and general exercise participation. SUS data were analyzed using a paired sample t-test and qualitative data were analyzed through conventional content analysis. RESULTS: Wheelchair users exercised for improved physical and mental health, as well as for functional independence, and community participation; however, lack of accessible equipment was a prominent barrier. Both the aROW and ACE have high usability, but the aROW was perceived as more enjoyable and effective for cardiovascular exercise. CONCLUSIONS: The implementation of the aROW into community gyms has the potential to help close the existing gap in inclusive equipment and may help people with disabilities to be more fully included in their community and lead healthier lives.Implications for rehabilitationWheelchair users perceive exercise as a meaningful activity that enhances physical health and risk of disease, functional independence, community participation, and overall social and emotional health.The adapted rowing machine was perceived as highly usable and was felt to be more enjoyable and effective for cardiovascular exercise compared to traditional arm crank ergometers.The adaptive rower provides an additional accessible equipment option for wheelchair users to obtain effective cardiovascular exercise.More available equipment may increase community participation and promote inclusion for wheelchair users.

Offline and Real-Time Implementation of a Terrain Classification Pipeline for Pushrim-Activated Power-Assisted Wheelchairs.

Pushrim-activated power-assisted wheelchairs (PAPAWs) are assistive technologies that provide propulsion assist to wheelchair users and enable access to various indoor and outdoor terrains. Therefore, it is beneficial to use PAPAW controllers that adapt to different terrain conditions. To achieve this objective, terrain classification techniques can be used as an integral part of the control architecture. Previously, the feasibility of using learning-based terrain classification models was investigated for offline applications. In this paper, we examine the effects of three model parameters (i.e., feature characteristics, terrain types, and the length of data segments) on offline and real-time classification accuracy. Our findings revealed that Random Forest classifiers are computationally efficient and can be used effectively for real-time terrain classification. These classifiers have the highest performance accuracy when used with a combination of time- and frequency-domain features. Additionally, we found that increasing the number of data points used for terrain estimation improves the prediction accuracy. Finally, our results revealed that classification accuracy can be improved by considering terrains with similar characteristics under one umbrella group. These findings can contribute to the development of real-time adaptive controllers that enhance PAPAW usability on different terrains.

Comparison of Manual Wheelchair and Pushrim-Activated Power-Assisted Wheelchair Propulsion Characteristics during Common Over-Ground Maneuvers.

Pushrim-activated power-assisted wheels (PAPAWs) are assistive technologies that use force sensor data to provide on-demand propulsion assistance to manual wheelchair users. However, available data about kinetic and kinematic of PAPAW use are mainly limited to experiments performed on a treadmill or using a dynamometer. In this work, we performed experiments to gather kinetics of wheelchair propulsion and kinematics of wheelchair motion for a variety of over-ground wheelchair maneuvers with a manual wheelchair with and without PAPAWs. Our findings revealed that using PAPAWs can significantly reduce the propulsion effort and push frequency. Both linear and angular velocities of the wheelchair were significantly increased when using PAPAWs. Less force and push frequency could potentially reduce risk of chronic upper limb injury. Higher linear velocity could be desirable for various daily life activities; however; the increase in the angular velocity could lead to unintended deviations from a desired path. Future research could investigate PAPAW controllers that amplify the desired intentions of users while mitigating any unwanted behaviours.

The Impact of COVID-19-Related Restrictions on Social and Daily Activities of Parents, People With Disabilities, and Older Adults: Protocol for a Longitudinal, Mixed Methods Study.

BACKGROUND: The COVID-19 pandemic has led to wide-scale changes in societal organization. This has dramatically altered people's daily activities, especially among families with young children, those living with disabilities such as spinal cord injury (SCI), those who have experienced a stroke, and older adults. OBJECTIVE: We aim to (1) investigate how COVID-19 restrictions influence daily activities, (2) track the psychosocial effects of these restrictions over time, and (3) identify strategies to mitigate the potential negative effects of these restrictions. METHODS: This is a longitudinal, concurrent, mixed methods study being conducted in British Columbia (BC), Canada. Data collection occurred at four time points, between April 2020 and February 2021. The first three data collection time points occurred within phases 1 to 3 of the Province of BC's Restart Plan. The final data collection coincided with the initial distribution of the COVID-19 vaccines. At each time point, data regarding participants' sociodemographics, depressive and anxiety symptoms, resilience, boredom, social support, instrumental activities of daily living, and social media and technology use were collected in an online survey. These data supplemented qualitative videoconference interviews exploring participants' COVID-19-related experiences. Participants were also asked to upload photos representing their experience during the restriction period, which facilitated discussion during the final interview. Five groups of participants were recruited: (1) families with children under the age of 18 years, (2) adults with an SCI, (3) adults who experienced a stroke, (4) adults with other types of disabilities, and (5) older adults (>64 years of age) with no self-reported disability. The number of participants we could recruit from each group was limited, which may impact the validity of some subgroup analyses. RESULTS: This study was approved by the University of British Columbia Behavioural Research Ethics Board (Approval No. H20-01109) on April 17, 2020. A total of 81 participants were enrolled in this study and data are being analyzed. Data analyses are expected to be completed in fall 2021; submission of multiple papers for publication is expected by winter 2021. CONCLUSIONS: Findings from our study will inform the development and recommendations of a new resource guide for the post-COVID-19 period and for future public health emergencies.

Scoping review of propelling aids for manual wheelchairs.

Manual wheelchair (MWC) users face a variety of obstacles limiting their participation. Different MWC models and new add-on components intended to improve propulsion may impact users' function and participation, although there is a lack of research on this topic. The aims of this study were to: 1) identify MWC propelling aids (PA) that are reported in the literature; 2) classify the outcomes used to evaluate the influence of PA according to the International Classification of Functioning, Disability and Health (ICF); and 3) summarize evidence for the influence of PA. A scoping review was conducted in 2017 using Pubmed, Medline, Embase, CINAHL, Compendex, IEEE Xplore, RESNA and ISS proceedings, Google, and Google Scholar. The content of each manuscript was assessed by two independent reviewers. A total of 28 PA (19 human-powered; 9 power-assisted) were identified from 163 manuscripts. The three most cited ICF subdomains were "Activity & Participation" (n = 125), "Body Function" (n = 100), and "Personal Factors" (n = 55). The findings suggest an overall positive influence of PA on various ICF domains/subdomains, but initial findings should be interpreted with caution. Confirmation of the effect and safety of PA requires higher levels of evidence.

Outdoor recreation among wheeled mobility users: perceived barriers and facilitators.

PURPOSE: Participation in outdoor recreation is associated with improvements in mental, emotional, and physical health. Individuals with impairments affecting mobility, such as wheelchair users, face environmental, physical, and social barriers to participation in outdoor recreation. There is limited research on outdoor recreation participation among wheelchair users, especially concerning informal recreational opportunities. Formal programmes that offer access to outdoor recreation are often oversubscribed and also do not enable opportunities to participate more spontaneously. OBJECTIVES: (1) To explore the experiences and impact of participation in outdoor recreation activities by wheelchair users, with an emphasis on more informal activities; and (2) to identify perceived barriers and facilitators to participation in outdoor recreation activities. METHODS: Semi-structured interviews were the main means of data collection in this interpretive description study; this was supplemented by photographs of activity involvement provided by participants. These data were analysed thematically. RESULTS: Fifteen Canadian wheelchair users participated in the study. Three themes emerged following analysis: (1) Into the Woods explores participants' current outdoor recreation experiences, (2) Ain't No Mountain High Enough looks at the barriers and challenges participants face, and (3) Just Around the Riverbend discusses participants' desired changes to enable their further participation. CONCLUSIONS: The study highlighted participants' current experiences, their perceived barriers, and several ways to enhance outdoor recreation participation among wheelchair users, including: developing new adaptations, creating policies, increasing access to affordable equipment and programmes, and reducing barriers in built and natural environments.Implications for rehabilitationWheelchair users participate in a wide variety of outdoor activities.Wheelchair users experience various barriers and challenges when participating in outdoor recreation.Despite recent improvements, environmental changes are needed to allow wheelchair users to access outdoor recreation.Further development of adaptive equipment is needed in order for wheelchair users to access their desired outdoor recreation activities.
