Abstract
Monitoring joystick operations in power wheelchairs (PWCs) is promising for investigating user-wheelchair interaction and providing quantitative measures to assess the user's driving performance. In this paper, an add-on measurement system, Power Wheelchair Maneuvering Logger (PWhML), is developed to provide an easy-to-implement and cost-effective solution for monitoring the user's joystick operations in PWCs. The proposed system uses two compact inertial measurement units (IMUs), which are respectively attached to the joystick and wheelchair armrest for movement sensing. A coordinate transformation-based method is proposed to estimate the joystick operating angles using the acceleration data measured by the attached IMUs. The accuracy of the proposed method was thoroughly evaluated under different conditions. The evaluation trials in a stationary PWC reported a mean absolute error (MAE) of 0.59° in the forward/backward direction and 0.64° in the leftward/rightward direction, validating the established geometry model for coordinate transformation. The subsequent driving experiments on outdoor test courses demonstrated the effectiveness and robustness of the proposed method in various terrain conditions (MAE of less than 3°). A clustering analysis based on the t-distributed stochastic neighborhood embedding method correctly categorized different driving activities using the joystick operating angles measured by PWhML. These results indicate that integrating the developed PWhML into PWCs can facilitate a quantitative measurement of the user's driving behavior, providing valuable insights to identify careless operation patterns and help PWC users to improve driving performance.

Nuri RP, Xu X, Aldersey HM. Users' satisfaction and experiences in using assistive devices distributed by a rehabilitation centre in Bangladesh: a cross-sectional study. Disabil Rehabil Assist Technol 2024; 19:868-877. [PMID: 36215415 DOI: 10.1080/17483107.2022.2129849] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2022] [Revised: 09/18/2022] [Accepted: 09/22/2022] [Indexed: 10/17/2022]
Abstract
PURPOSE This study aimed to understand Bangladeshi users' satisfaction with their assistive devices, including (a) device characteristics, e.g., size, weight, safety, ease of use, comfort, and effectiveness, and (b) availability of parts and repair services. We also described how frequently individuals with disabilities living in the community used assistive devices in their daily activities and how the use of assistive devices promoted individuals' wellbeing. METHOD We conducted a cross-sectional survey with assistive device users or their guardians (if under 18) in Bangladesh about their experience and satisfaction with their assistive device 6 months after receiving it. The research team developed a survey questionnaire consisting of both closed and open-ended questions. All data were collected via telephone interviews. We employed descriptive statistics to analyse quantitative data and inductive analysis for the qualitative data. RESULTS We found that out of the 376 participants, nearly 95% used assistive devices on a regular basis, and their satisfaction with the devices was high. Participants reported that assistive devices improved mobility, independence, and wellbeing of persons with disabilities. A few participants (6.4%) reported that their devices were damaged. Some participants identified concerns with their assistive devices, including (i) inappropriate size of ankle-foot orthoses, manual self-propelled wheelchairs, and prostheses, (ii) back slabs (a type of brace) being too short, and (iii) walking frames being too large. Several participants noted pain and discomfort when they used their assistive device. Additionally, some participants stated that environmental factors (e.g., muddy roads) contributed to the disrepair of their assistive devices. Finally, participants recounted that repair services were limited in rural areas of Bangladesh. CONCLUSION These findings indicate that the provision of assistive devices requires accommodating individuals' needs and ensuring appropriate environments in which to function. The results support the need for follow-up services after distributing assistive devices. Further research could explore the impact of assistive devices on the family quality of life of persons with disabilities.IMPLICATIONS FOR REHABILITATIONIt is essential for rehabilitation professionals to conduct follow-up services after distributing assistive devices among persons with disabilities.There is a need for the government of Bangladesh to revisit the Rights and Protection of Persons with Disability Act of 2013 and provide further clarity about their commitment to the provision of assistive devices and associated services (e.g., repair services) and its subsequent implementation.Policymakers in Bangladesh must be proactive to translate policy commitments into practice, as it relates to building an accessible environment for people using assistive devices. Further, government efforts are needed to educate policy implementers in all relevant ministries so that all responsible bodies are fully familiar with their national and international commitments regarding the rights of persons with disabilities.Future research could (i) include user's satisfaction with the service delivery process and (ii) measure the impact of assistive devices on family quality of life of persons with disabilities.

Abstract
BACKGROUND The complex task of Electric Powered Wheelchairs (EPW) prescription relies mainly on personal experience and subjective observations despite standardized processes and protocols. The most informative measurements come from joystick monitoring, but recording direct joystick outputs require to disassemble the joystick. We propose a new solution called "SenseJoy" that is easy to plug on a joystick and is suitable to characterize the driver behavior by estimating the joystick command. METHODS SenseJoy is a pluggable system embedded on EPW built with a 3D accelerometer and a 2D gyrometer placed within the joystick and another 3D accelerometer located at the basis of the joystick. Data is sampled at 39 Hz and processed offline. First, SenseJoy sensitivity is assessed on wheelchair driving tasks performed by a group of 8 drivers (31 ± 8 years old, including one driver with left hemiplegia, one with cerebral palsy) in a lab environment. Direct joystick measurements are compared with SenseJoy estimations in different driving exercises. A second group of 5 drivers is recorded in the ecological context of a rehabilitation center (41 ± 10 years old, with two tetraplegic drivers, one tetraplegic driver with cognitive disorder, one driver post-stroke, one driver with right hemiplegia). The measurements from all groups of drivers are evaluated with an unsupervised statistical analysis, to estimate driving profile clusters. RESULTS The SenseJoy is able to measure the EPW joystick inclination angles with a resolution of 1.31% and 1.23% in backward/forward and left/right directions respectively. A statistical validation ensures that the classical joystick-based indicators are equivalent when acquired with the SenseJoy or with a direct joystick output connection. Using an unsupervised methodology, based on a similarity matrix between subjects, it is possible to characterize the driver profile from real data. CONCLUSION SenseJoy is a pluggable system for assessing the joystick controls during EPW driving tasks. This system can be plugged on any EPW equipped with a joystick control interface. We demonstrate that it correctly estimates the performance indicators and it is able to characterize driving profile. The system is suitable and efficient to assist therapists in their recommendation, by providing objective measures with a fast installation process.

Abstract
INTRODUCTION A wide range of products are available to assist mobility, and it is, therefore, of great importance to obtain empirical information regarding the expected impact of the use of these products based on outcome measures. People affected by neurological disorders often use products to assist mobility such as wheelchairs (both manual self-propelled wheelchairs and externally propelled chairs such as electric wheelchairs), walkers, walking sticks, etc. It is important to conduct an assessment of the psychosocial impact of these products on the lives of affected people. METHODS We performed this assessment using the Psychosocial Impact of Assistive Devices Scale (PIADS) and a socio-demographic questionnaire. RESULTS The results showed greater psychosocial benefits relating to the use of electric wheelchairs in comparison with walking sticks or manual, non-self-propelled chairs. Moreover, significant differences are present in the three subscales of the PIADS in relation to variables such as age, training in the use of assistive technology (AT) and funding. CONCLUSION Therefore, we conclude that the use of AT should be promoted among this group as a way to improve their adaptability, competency and self-esteem, and to reduce limits on participation deriving from the physical and contextual barriers faced by this collective.Implications for rehabilitationAmong the assessment of different mobility AT displaying a higher score in the three subscales of the PIADS amongst people using electric wheelchairs than among those using non-self-propelled manual wheelchairs. On the other hand, we found that the walker has a significant score only in the competence subscale. Canes, for example the stick 4-p is significant in the three subscales, or the walking cane in terms of competence. Despite the fact that crutches and walking sticks obtained the lowest score in this study.Not only the assessment is necessary, but also the adjustment of AT to the person who is going to use it, as well as some training on how to use it. Only 23.8% of the participants received training in the use of their main assistive device in this study.The results seem to indicate that for elder users, the score on adaptability with the AT is lower. That may result in future lines of research in usability and improving in terms of the needs of end-users and these AT since a high percentage of people with neurological conditions are elder people.The application of specific scales such as PIADS that helps to measure the use and capacity of the AT prescribed to patients with neurological disease provides more informed clinical reasoning.

Abstract
Background Because resources are limited in low- and middle-income countries (LMIC), the development of outcome measures is of interest. Wheelchair outcome measures are useful to support evidence-based practice in wheelchair provision. Objectives The Wheelchair Interface Questionnaire (WIQ) is being developed to provide a professional perspective on the quality of the interface between a wheelchair and its user. This article discusses the development of the WIQ and its face and content validity. Method During field studies in Kenya, we sought to include professional report data on the wheelchair–user interface that could be analysed to inform design changes. None of the existing measures was focused on the interface between users and their wheelchairs. The WIQ was developed to meet this need. To investigate face and content validity, 24 experienced wheelchair professionals participated in a study that included two rounds of an online survey and a focus group in Kenya. Results Responses were categorised by topic and the WIQ was modified following each iteration. Participants affirmed the usefulness of a brief professional report measure to provide a snapshot of the user–wheelchair interface. Participants emphasised the importance of brevity, wide applicability and provision of specific feedback for wheelchair modification or design changes. The focus group agreed that the final version provided useful data and was applicable to virtually all wheelchair users in LMIC. Conclusion These preliminary studies indicate initial face and content validity of the WIQ as a method for providing a professional perspective on the interface between a user and his or her wheelchair. Keywords Outcome measure; wheelchair assessment; user–wheelchair interface; wheelchair appropriateness; professional report.

Abstract
Background: Evidence-based practice (EBP) in seating and wheeled mobility practice is often hindered by a dearth of published research.Purpose: The purpose of this review was to explore and critically appraise the use of single-subject research designs (SSRDs) in seating and wheeled mobility studies published between January 1995 and May 2018.Study Selection: Primary source, peer-reviewed SSRDs focused on exploring the impact of a seating and wheeled mobility intervention were included in the review.Data Extraction: Relevant data extraction, determination of level of evidence, evaluation of methodological rigor, and assessment of the risk of bias were each independently performed.Data Synthesis: The review yielded 19 studies (2 Level III, 15 Level IV, and 2 Level V). A majority of these studies incorporated a withdrawal-type of SSRD and involved subjects representing patient populations with seating and wheeled mobility needs. Methodological rigor/quality features most commonly absent in the included studies included: blinding/masking, inter-rater or intra-rater reliability, >5 data points in each phase, planned replication (≥3 subjects), procedural fidelity methods, randomization, stability of the data during baseline, statistical analyses and use of subject selection criteria. The limited number of published SSRDs, combined with the lower levels of evidence (Levels III-V) provided by these studies, indicates that the use of SSRDs in seating and wheeled mobility research is in the early stages of development.Conclusions: Increasing the methodological quality and rigor as well as reporting methods in future SSRDs involving seating and wheeled mobility interventions may help to support EBP in this area.Implications for RehabilitationSingle-subject research designs (SSRDs) offer both researchers and clinicians the opportunity to contribute to the existing knowledge base in ways that reflect actual clinical practice.SSRDs provide flexibility in adapting and modifying seating and wheeled mobility-related assistive technology devices to meet the individual needs of specific subjects.SSRDs preserve individual responses to seating and wheeled mobility-related assistive technology devices.SSRDs may help to enhance evidence-based practice (EBP) in seating and wheeled mobility practice by spanning the divide between research and practice.Increasing the methodological quality and rigor as well as reporting methods in future SSRDs may help to support EBP in seating and wheeled mobility practice.

Abstract
BACKGROUND. Adaptive equipment (AE) is frequently provided during stroke rehabilitation by occupational therapists. PURPOSE. This study aimed to identify the AE that people typically use after a stroke and the outcomes achieved as a result, and to explore people's experiences obtaining and using AE, to inform both practice and policy in this field. METHOD. A mixed-methods study, involving a postal questionnaire and interviews, used descriptive statistics and grounded theory to analyze the quantitative and qualitative data, respectively. FINDINGS. Questionnaire data ( n = 258) revealed mobility AE was issued most frequently, with increased safety as the primary reported outcome. Interview data ( n = 15) indicated relationships with health professionals and the hospital environment shaped early AE selection and use. Once home, making sense of AE and community participation were more influential. IMPLICATIONS. Therapeutic relationships and reflection time are critical to maximize AE use after stroke. Policy and related funding for AE need to prioritize community participation.

Abstract
BACKGROUND Children with severe disabilities are sometimes unable to access powered mobility training. Thus, we developed the Kinect-Wheelchair Interface Controlled (KWIC) smart wheelchair trainer that converts a manual wheelchair into a powered wheelchair. The KWIC Trainer uses computer vision to create a virtual tether with adaptive shared-control between the wheelchair and a therapist during training. It also includes a mixed-reality video game system. METHODS We performed a year-long usability study of the KWIC Trainer at a local clinic, soliciting qualitative and quantitative feedback on the device after extended use. RESULTS Eight therapists used the KWIC Trainer for over 50 hours with 8 different children. Two of the children obtained their own powered wheelchair as a result of the training. The therapists indicated the device allowed them to provide mobility training for more children than would have been possible with a demo wheelchair, and they found use of the device to be as safe as or safer than conventional training. They viewed the shared control algorithm as counter-productive because it made it difficult for the child to discern when he or she was controlling the chair. They were enthusiastic about the video game integration for increasing motivation and engagement during training. They emphasized the need for additional access methods for controlling the device. CONCLUSION The therapists confirmed that the KWIC Trainer is a useful tool for increasing access to powered mobility training and for engaging children during training sessions. However, some improvements would enhance its applicability for routine clinical use.

Abstract
Over 50 million United States citizens (1 in 6 people in the US) have a developmental, acquired, or degenerative disability. The average US citizen can expect to live 20% of his or her life with a disability. Rehabilitation technologies play a major role in improving the quality of life for people with a disability, yet widespread and highly challenging needs remain. Within the US, a major effort aimed at the creation and evaluation of rehabilitation technology has been the Rehabilitation Engineering Research Centers (RERCs) sponsored by the National Institute on Disability, Independent Living, and Rehabilitation Research. As envisioned at their conception by a panel of the National Academy of Science in 1970, these centers were intended to take a "total approach to rehabilitation", combining medicine, engineering, and related science, to improve the quality of life of individuals with a disability. Here, we review the scope, achievements, and ongoing projects of an unbiased sample of 19 currently active or recently terminated RERCs. Specifically, for each center, we briefly explain the needs it targets, summarize key historical advances, identify emerging innovations, and consider future directions. Our assessment from this review is that the RERC program indeed involves a multidisciplinary approach, with 36 professional fields involved, although 70% of research and development staff are in engineering fields, 23% in clinical fields, and only 7% in basic science fields; significantly, 11% of the professional staff have a disability related to their research. We observe that the RERC program has substantially diversified the scope of its work since the 1970's, addressing more types of disabilities using more technologies, and, in particular, often now focusing on information technologies. RERC work also now often views users as integrated into an interdependent society through technologies that both people with and without disabilities co-use (such as the internet, wireless communication, and architecture). In addition, RERC research has evolved to view users as able at improving outcomes through learning, exercise, and plasticity (rather than being static), which can be optimally timed. We provide examples of rehabilitation technology innovation produced by the RERCs that illustrate this increasingly diversifying scope and evolving perspective. We conclude by discussing growth opportunities and possible future directions of the RERC program.

Abstract
Background Comparative effectiveness research on wheelchairs available in low-resource areas is needed to enable effective use of limited funds. Mobility on commonly encountered rolling environments is a key aspect of function. High variation in capacity among wheelchair users can mask changes in mobility because of wheelchair design. A repeated measures protocol in which the participants use one type of wheelchair and then another minimises the impact of individual variation. Objectives The Aspects of Wheelchair Mobility Test (AWMT) was designed to be used in repeated measures studies in low-resource areas. It measures the impact of different wheelchair types on physical performance in commonly encountered rolling environments and provides an opportunity for qualitative and quantitative participant response. This study sought to confirm the ability of the AWMT to discern differences in mobility because of wheelchair design. Method Participants were wheelchair users at a boarding school for students with disabilities in a low-resource area. Each participant completed timed tests on measured tracks on rough and smooth surfaces, in tight spaces and over curbs. Four types of wheelchairs designed for use in low-resource areas were included. Results The protocol demonstrated the ability to discriminate changes in mobility of individuals because of wheelchair type. Conclusion Comparative effectiveness studies with this protocol can enable beneficial change. This is illustrated by design alterations by wheelchair manufacturers in response to results.

Abstract
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.

Associations Between Resilience, Community Belonging, and Social Participation Among Community-Dwelling Older Adults: Results From the Eastern Townships Population Health Survey. Arch Phys Med Rehabil 2017; 98:2422-2432. [PMID: 28455192 DOI: 10.1016/j.apmr.2017.03.025] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2016] [Revised: 03/24/2017] [Accepted: 03/30/2017] [Indexed: 10/19/2022]
Abstract
OBJECTIVE To examine the associations between resilience, community belonging, and social participation, and the moderating effect of resilience on the association between community belonging and social participation among community-dwelling older adults. DESIGN Cross-sectional; secondary analyses of the Eastern Townships Population Health Survey. SETTING Community. PARTICIPANTS A sample (N=4541) of women (n=2485) and men (n=2056) aged ≥60 years was randomly selected according to area. Most participants had <14 years of schooling, owned their dwelling, were retired, had 1 or 2 chronic conditions, and did not have depressive symptoms. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Self-reported data on age, education, depressive symptoms, social participation, community belonging, and resilience were collected by phone interviewer-administered questionnaire. A social participation scale measured frequency of participation in 8 community activities. A 4-point Likert scale ranging from "very strong" to "very weak" estimated sense of belonging to the local community. Social participation and sense of belonging questions came from Statistics Canada surveys. Resilience was assessed with the 10-item Connor-Davidson Resilience Scale, capturing the ability to cope with adversity. RESULTS Controlling for age, education, and psychological distress, greater resilience and community belonging were associated with greater social participation among women (R2=.13; P<.001) and men (R2=.09; P<.001). The association between community belonging and social participation varied as a function of resilience, especially in men. Greater community belonging further enhanced social participation, especially among women (P=.03) and men (P<.01) with greater resilience (moderator effect). CONCLUSIONS Resilience moderates the association between community belonging and social participation among community-dwelling older women and, especially, men. Interventions targeting social participation should consider the potential impact of resilience on improving community belonging. Future studies should investigate why resilience moderates associations between community belonging and social participation, and how to enhance resilience among older adults.

Abstract
PURPOSE To synthesize qualitative study findings on the meaning ascribed to wheelchairs and wheeled mobility devices (WMD) by WMD users. METHOD Bibliographic databases were systematically searched up to January 2015 to identify relevant papers. Reviewers selected studies, assessed methodological quality and thematically synthesized findings using a metasynthesis process described by Thomas and Harden (2008). RESULTS Twenty articles were included. Four descriptive themes emerged: physical environment interaction; sociocultural experiences; participation in activities and occupations; and WMD-self relationship. WMD use was found to be a complex experience that can fluctuate through interaction with aspects of the environment and opportunities for participation. The analytic theme, dynamic duality of WMD experience, addressed the simultaneous enabling and disabling aspects of WMD use. CONCLUSIONS Metasyntheses enable researchers to gain a deeper understanding of issues by examining findings across studies. Findings of this study provide a framework for understanding the complexity of WMD use. The framework has practical applications for clinicians and users of WMD in understanding the experience of WMD to be neither singular nor static. Implications for Rehabilitation The meaning of wheeled mobility device (WMD) use is dynamically influenced by the environment and opportunities afforded for occupational and social participation. A duality of experiences can emerge for WMD users, where wheeled mobility use can be at the same time positive and negative, based on the interaction with the environment. Clinicians need to determine the meaning that each individual user ascribes to the WMD, and to consider how that meaning may change over time. By understanding the meaning ascribed to WMD use by individuals, clinicians can be better prepared to work with the WMD users to address negative reinforcers of the experience in physical and sociocultural environments as well as highlighting the positive experiences.

Abstract
Recent studies have used data loggers to record a wide range of, sometimes differing, objective outcomes associated with the use of manual wheelchairs. To identify which outcomes are broadly perceived to be the most important to measure when objectively documenting manual wheelchair use, a cross-sectional survey was conducted with groups of researchers and clinicians in the field of wheeled mobility. We also surveyed the challenges these groups experienced when using data loggers. The survey was informed by a previous scoping review of the scientific and gray literature. Seventy-four people with various academic and professional backgrounds completed the survey: 57 researchers (77.0%) and 17 clinicians (23.0%). Regarding the importance they attributed to commonly measured outcomes, the most highly rated outcome identified by both groups was "distance traveled." There were significant differences between the groups' perspectives in rating and ranking the importance of "pressure-relief activities," "seat pressure," and "acceleration." In terms of challenges or barriers associated with the use of data loggers for monitoring manual wheelchair use, it appears that researchers and clinicians have relatively similar needs and preferences. However, only clinicians reported that the time they wanted to, or could, allocate to review recorded information was a potential hardship. Our hope is that these results will help further development and increase the functionality and applicability of data loggers for manual wheelchairs in research and clinical contexts.

Abstract
In recent years, studies have increasingly employed data logger technologies to record objective driving and physiological characteristics of manual wheelchair users. However, the technologies used offer significant differences in characteristics, such as measured outcomes, ease of use, and level of burden. In order to identify and describe the extent of published research activity that relies on data logger technologies for manual wheelchair users, we performed a scoping review of the scientific and gray literature. Five databases were searched: Medline, Compendex, CINAHL, EMBASE, and Google Scholar. The 119 retained papers document a wide variety of logging devices and sensing technologies measuring a range of outcomes. The most commonly used technologies were accelerometers installed on the user (18.8%), odometers installed on the wheelchair (12.4%), accelerometers installed on the wheelchair (9.7%), and heart monitors (9.7%). Not surprisingly, the most reported outcomes were distance, mobility events, heart rate, speed/velocity, acceleration, and driving time. With decreasing costs and technological improvements, data loggers are likely to have future widespread clinical (and even personal) use. Future research may be needed to assess the usefulness of different outcomes and to develop methods more appropriate to wheelchair users in order to optimize the practicality of wheelchair data loggers.

Abstract
OBJECTIVES To identify suitable tools for measuring important elements of participation for children, aged 18 months to 12 years, who need or use power mobility, and to indicate which tools should be considered for inclusion in a measurement toolkit. METHODS Parents, therapists and researchers with expertise in paediatric power mobility and participation (n = 70) completed an online modified Delphi survey, with consensus set a priori >80% agreement. Existing tools were matched against participation elements ranked most important for those in early childhood (18 months-5 years) and of school-age (6-12 years) by the panel. RESULTS Six out of 13 tools demonstrated potential, meeting at least three elements each, although none addressed all elements deemed important to measure by the panel. Only the Participation and Environment Measure for Children and Youth (PEM-CY) reached consensus for inclusion in a participation measure toolkit. CONCLUSION Further evaluation of these tools with this population is warranted.

Abstract
Several groups have developed brain-machine-interfaces (BMIs) that allow primates to use cortical activity to control artificial limbs. Yet, it remains unknown whether cortical ensembles could represent the kinematics of whole-body navigation and be used to operate a BMI that moves a wheelchair continuously in space. Here we show that rhesus monkeys can learn to navigate a robotic wheelchair, using their cortical activity as the main control signal. Two monkeys were chronically implanted with multichannel microelectrode arrays that allowed wireless recordings from ensembles of premotor and sensorimotor cortical neurons. Initially, while monkeys remained seated in the robotic wheelchair, passive navigation was employed to train a linear decoder to extract 2D wheelchair kinematics from cortical activity. Next, monkeys employed the wireless BMI to translate their cortical activity into the robotic wheelchair’s translational and rotational velocities. Over time, monkeys improved their ability to navigate the wheelchair toward the location of a grape reward. The navigation was enacted by populations of cortical neurons tuned to whole-body displacement. During practice with the apparatus, we also noticed the presence of a cortical representation of the distance to reward location. These results demonstrate that intracranial BMIs could restore whole-body mobility to severely paralyzed patients in the future.

Abstract
AIM This study aims to address the gap in research and contribute to the body of knowledge on the perspectives assistive technology device users have toward their devices. METHOD Mixed methods were used to better understand the impact of mobility assistive technology devices (MATDs) on participation for individuals with disabilities. The Functional Mobility Assessment was administered in conjunction with two qualitative questions developed by the research team allowing participants to expound on the impact of their MATD experience. Participants were recruited online via the National Spinal Cord Injury Association website and in-person at Abilities Expo in Atlanta, Georgia, and the International Seating Symposium in Nashville, Tennessee. RESULTS Results are consistent with findings from prior research regarding accessibility for individuals with disabilities. Corresponding findings were found in both the quantitative and qualitative data and are categorized into several major themes: environment (indoor and outdoor), surface heights, transportation, dependence, independence, quality of life and participation. CONCLUSION Quantitative data from this study indicate that users of MATD are satisfied with the way in which their devices enable maneuvering indoors, while qualitative data suggest otherwise. Implications for healthcare practitioners are described and future recommendations are provided. Implications for Rehabilitation Healthcare professionals should advocate for proper mobility assistive technology devices (MATDs) for their patients in order to enable increased independence, safety and efficiency. Healthcare professionals must be cognizant of the impact of the environment and/or environmental barriers when prescribing MATD. Additional areas of interest for future research may include investigating the impact of MATD in association with date of onset of disability, according to diagnoses, or specific to length of time since acquiring the device.

Abstract
PURPOSE This study was conducted to compare the performance of three types of chairs in a low-resource setting. The larger goal was to provide information which will enable more effective use of limited funds by wheelchair manufacturers and suppliers in low-resource settings. METHODS The Motivation Rough Terrain and Whirlwind Rough Rider were compared in six skills tests which participants completed in one wheelchair type and then a day later in the other. A hospital-style folding transport wheelchair was also included in one test. For all skills, participants rated the ease or difficulty on a visual analogue scale. For all tracks, distance traveled and the physiological cost index were recorded. Data were analyzed using repeated measures analysis of variance. RESULTS The Motivation wheelchair outperformed Whirlwind wheelchair on rough and smooth tracks, and in some metrics on the tight spaces track. Motivation and Whirlwind wheelchairs significantly outperformed the hospital transport wheelchair in all metrics on the rough track skills test. CONCLUSION This comparative study provides data that are valuable for manufacturers and for those who provide wheelchairs to users. The comparison with the hospital-style transport chair confirms the cost to users of inappropriate wheelchair provision. Implications for Rehabilitation For those with compromised lower limb function, wheelchairs are essential to enable full participation and improved quality of life. Therefore, provision of wheelchairs which effectively enable mobility in the cultures and environments in which people with disabilities live is crucial. This includes low-resource settings where the need for appropriate seating is especially urgent. A repeated measures study to measure wheelchair performances in everyday skills in the setting where wheelchairs are used gives information on the quality of mobility provided by those wheelchairs. This study highlights differences in the performance of three types of wheelchairs often distributed in low-resource settings. This information can improve mobility for wheelchair users in those settings by enabling wheelchair manufacturers to optimize wheelchair design and providers to optimize the use of limited funds.

Abstract
Using a powered wheelchair (PW) is a complex task requiring advanced perceptual and motor control skills. Unfortunately, PW incidents and accidents are not uncommon and their consequences can be serious. The objective of this paper is to develop technological tools that can be used to characterize a wheelchair user’s driving behavior under various settings. In the experiments conducted, PWs are outfitted with a datalogging platform that records, in real-time, the 3-D acceleration of the PW. Data collection was conducted over 35 different activities, designed to capture a spectrum of PW driving events performed at different speeds (collisions with fixed or moving objects, rolling on incline plane, and rolling across multiple types obstacles). The data was processed using time-series analysis and data mining techniques, to automatically detect and identify the different events. We compared the classification accuracy using four different types of time-series features: 1) time-delay embeddings; 2) time-domain characterization; 3) frequency-domain features; and 4) wavelet transforms. In the analysis, we compared the classification accuracy obtained when distinguishing between safe and unsafe events during each of the 35 different activities. For the purposes of this study, unsafe events were defined as activities containing collisions against objects at different speed, and the remainder were defined as safe events. We were able to accurately detect 98% of unsafe events, with a low (12%) false positive rate, using only five examples of each activity. This proof-of-concept study shows that the proposed approach has the potential of capturing, based on limited input from embedded sensors, contextual information on PW use, and of automatically characterizing a user’s PW driving behavior.

Abstract
Background Many older adults rely on a manual wheelchair for mobility but typically receive little, if any, training on how to use their wheelchair effectively and independently. Standardized skill training is an effective intervention, but limited access to clinician trainers is a substantive barrier. Enhancing Participation in the Community by Improving Wheelchair Skills (EPIC Wheels) is a 1-month monitored home training program for improving mobility skills in older novice manual wheelchair users, integrating principles from andragogy and social cognitive theory. The purpose of this study is to determine whether feasibility indicators and primary clinical outcome measures of the EPIC Wheels program are sufficiently robust to justify conducting a subsequent multi-site randomized controlled trial. Methods A 2 × 2 factorial randomized controlled trial at two sites will compare improvement in wheelchair mobility skills between an EPIC Wheels treatment group and a computer-game control group, with additional wheelchair use introduced as a second factor. A total of 40 community-dwelling manual wheelchair users at least 55 years old and living in two Canadian metropolitan cities (n = 20 × 2) will be recruited. Feasibility indicators related to study process, resources, management, and treatment issues will be collected during data collection and at the end of the study period, and evaluated against proposed criteria. Clinical outcome measures will be collected at baseline (pre-randomization) and post-intervention. The primary clinical outcome measure is wheelchair skill capacity, as determined by the Wheelchair Skills Test, version 4.1. Secondary clinical outcome measures include wheelchair skill safety, satisfaction with performance, wheelchair confidence, life-space mobility, divided-attention, and health-related quality of life. Discussion The EPIC Wheels training program offers several innovative features. The convenient, portable, economical, and adaptable tablet-based, home program model for wheelchair skills training has great potential for clinical uptake and opportunity for future enhancements. Theory-driven design can foster learning and adherence for older adults. Establishing the feasibility of the study protocol and estimating effect size for the primary clinical outcome measure will be used to develop a multi-site randomized controlled trial to test the guiding hypotheses. Trial registration Clinical Trials NCT01740635.

Abstract
PURPOSE The purpose of this article is to explore the use of Mobile Shower Commodes (MSCs) by adults with Spinal Cord Injury (SCI) and to understand how adults with SCI and expert clinicians identify and select MSC designs and features. METHOD Semi-structured interviews were conducted with seven adults with SCI and eight expert clinical prescribers using semi-structured guides. Transcripts were analysed thematically using the Policy, Human, Activity, Assistance and Technology, and Environment (PHAATE) model as the underpinning theoretical framework. RESULTS Analysis of the interview transcripts revealed 3 themes and 12 sub-themes. The main themes were: (1) Activities, routines and interacting factors, (2) Features for functioning and (3) Getting it right. Substantial links existed between and across the themes and subthemes. CONCLUSIONS The use of MSCs by adults with SCI is complex. MSC performance varies across activities, and during interactions between the user, the MSC, other assistive technologies, assistance and physical environments. Future studies should explore service delivery processes and develop validated clinical assessment instruments and outcome measures for MSC provision. Implications for Rehabilitation Mobile shower commode use is complex, involving nine distinct activities and three types of routines. Mobile shower commodes used by Australian adults with SCI are individualised to users and include customisations and custom-made components. Trialling individualised mobile shower commodes prior to funding is problematic and not reflected in assistive service delivery models. Validated clinical instruments for assessing and selecting mobile shower commode features are needed.

Abstract
PURPOSE A primary goal for aging policy is to optimize independence in later life. We estimate the cross-sectional association between physical and social challenge in the home environment and use of assistive devices (AD) for mobility in the home, controlling for lower extremity physical performance (short physical performance battery [SPPB]) and other factors. DESIGN AND METHODS Data are from the Women's Health and Aging Study I, a prospective study of the factors related to physical disability in a sample of moderately to severely disabled older women. We describe these associations in the baseline sample overall and also within subsets who do and do not have both a baseline and a 3-year follow-up observation. RESULTS On average, physical challenge in the home environment is inversely associated with level of AD use (p < .05) in the overall sample, independent of SPPB, living alone, and other factors. We do not find a significant (p < .05) association between social challenge and the level of AD use in the overall sample. Findings by follow-up responder status were similar (with minor variability). IMPLICATIONS Future cohorts who are better educated and more receptive to technology may confront challenges in the home environment that limit their ability to age in place. Our findings suggest that the physical challenges of the home are significantly related to AD use. Future analyses that explore the mechanisms of the home environment as a source of challenges to independent functioning could help in the design of future interventions for these cohorts as they age.

Abstract
PURPOSE The current study explored domains of assistive technology (AT) device outcomes that are most valued by AT users. A secondary objective was to identify elements in the device acquisition process that affect outcomes. METHOD Focus groups were conducted at geographically dispersed locations within the USA. The groups were moderated by experienced AT practitioners who followed a detailed procedure emphasizing a nominal group facilitation technique. RESULTS Twenty-four adult AT users, representing a range of ages and disability populations, participated in four focus groups. Many had over 15 years of experience with multiple device types. Qualitative analysis yielded 13 threads that embodied salient outcome domains (e.g. independence, subjective well-being, participation in work and school, cost-effectiveness) and key factors associated with the device acquisition process (e.g. lengthy periods of frustration, variable quality of service providers). Ironically, these data were evoked only after the term "outcomes" was omitted from focus group questions. CONCLUSIONS AT outcomes studies are needed that report data regarding (a) the impact of AT on participation, (b) costs of AT provision and (c) key elements in the AT service delivery process. Future studies will be further strengthened to the extent that their methodologies actively assimilate consumer perspectives. Implications for Rehabilitation Consumers highly value the impact of AT devices on their independence, subjective well-being and participation in work and school. The process of acquiring assistive technology devices is often lengthy and frustrating for consumers. Future AT outcomes research should report descriptive data regarding service delivery processes, as well as long-term impacts for consumers. Practitioners and researchers should avoid the use of potentially confusing professional jargon when administering surveys to consumers.

Abstract
OBJECTIVES To assess the construct validity of the Level of Sitting Scale (LSS) by examining the relationship between LSS scores and the type and amount of seating supports. METHODS Secondary analysis of the data for 114 children ≤18 years, with neuromotor disorders who participated in a responsiveness study of the Seated Postural Control Measure. RESULTS A significant inverse relationship (Spearman rho = -0.42, p < 0.05) was found between LSS scores and amount of seating support provided. Statistically significant differences were also revealed between LSS levels of sitting ability (p < 0.004) and pelvic, thigh, trunk and head seating components and type of seating system, using Kruskal-Wallis test. CONCLUSION This study provides evidence of construct validity for the LSS in use as a discriminative measure of sitting ability in children with neuromotor disorders. Further validation is justified. Clinically intuitive associations between sitting ability and seating interventions were confirmed.

Abstract
OBJECTIVE To examine the associations between perceived proximity to neighborhood resources, disability, and social participation and the potential moderating effect of perceived proximity to neighborhood resources on the association between disability and social participation in community-dwelling older women and men. DESIGN Cross-sectional. SETTING Community. PARTICIPANTS Older adults (296 women, 258 men). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Data for age, education, depressive symptoms, frequency of participation in community activities, perceived proximity to neighborhood resources (services, amenities), and functional autonomy in daily activities (disability) were collected by means of interviewer-administered questionnaire. RESULTS Greater perceived proximity to resources and lower level of disability were associated with greater social participation for both women (R(2)=.10; P<.001) and men (R(2)=.05; P<.01). The association between disability and social participation did not vary as a function of perceived proximity to neighborhood resources in women (no moderating effect; P=.15). However, in men, greater perceived proximity to neighborhood resources enhanced social participation (P=.01), but only in those with minor or no disability. CONCLUSIONS Future studies should investigate why perceived proximity to services and amenities is associated with social participation in older men with minor or no disabilities and with women overall, but has no association in men with moderate disabilities.

Abstract
This paper presents a method to automatically recognize events and driving activities during the use of a powered wheelchair (PW). The method uses a support vector machine classifier, trained from sensor-based data from a datalogging platform installed on the PW. Data from a 3D accelerometer positioned on the back of the PW were collected in a laboratory space during PW driving tasks. 16-segmented events and driving activities (i.e. impacts from different side on different objects, rolling down or up on incline surface, going across threshold of different height) were performed repeatedly (n=25 trials) by one operator at three different speeds (slow, normal, high). We present results from an experiment aiming to classify five different events and driving activities from the sensor data acquired using the datalogging platform. Classification results show the ability of the proposed method to reliably segment 100% of events, and to identify the correct event type in 80% of events.

Abstract
Background Powered wheelchairs are essential for many individuals who have mobility impairments. Nevertheless, if operated improperly, the powered wheelchair poses dangers to both the user and to those in its vicinity. Thus, operating a powered wheelchair with some degree of proficiency is important for safety, and measuring driving skills becomes an important issue to address. The objective of this study was to explore the discriminate validity of outcome measures of driving skills based on joystick control strategies and performance recorded using a data logging system. Methods We compared joystick control strategies and performance during standardized driving tasks between a group of 10 expert and 13 novice powered wheelchair users. Driving tasks were drawn from the Wheelchair Skills Test (v. 4.1). Data from the joystick controller were collected on a data logging system. Joystick control strategies and performance outcome measures included the mean number of joystick movements, time required to complete tasks, as well as variability of joystick direction. Results In simpler tasks, the expert group's driving skills were comparable to those of the novice group. Yet, in more difficult and spatially confined tasks, the expert group required fewer joystick movements for task completion. In some cases, experts also completed tasks in approximately half the time with respect to the novice group. Conclusions The analysis of joystick control made it possible to discriminate between novice and expert powered wheelchair users in a variety of driving tasks. These results imply that in spatially confined areas, a greater powered wheelchair driving skill level is required to complete tasks efficiently. Based on these findings, it would appear that the use of joystick signal analysis constitutes an objective tool for the measurement of powered wheelchair driving skills. This tool may be useful for the clinical assessment and training of powered wheelchair skills.

Abstract
PURPOSE To document perceived impacts in users' daily activities and social roles (social participation) following the acquisition of a first manual or powered wheelchair. METHODS A qualitative design with a phenomenological approach was used. Semi-structured interviews were conducted. An interview guide was developed based on the 12 social participation categories in the Disability Creation Process (DCP) conceptual model as themes underlying the questions: 'What has changed in your daily life since you got your new wheelchair?' and 'What has not changed in your daily life that you thought you would do differently with your new wheelchair?' RESULTS AND DISCUSSION The average age of the ten participants was 64.3 years (±16.3) and 90% had received a manual wheelchair. Four main themes emerged from the detailed analysis: changes in daily activities, expectations not met, impacts on social roles and emotional changes. The participants considered the changes in daily activities to be generally positive. Expectations not met mainly related to outdoor mobility. The participants had not anticipated the impacts on social roles and emotional changes, which demonstrate the complexity of human occupation. CONCLUSION Getting a wheelchair is a major and complex event in a person's life.

Abstract
OBJECTIVES To review models and instruments for the selection and advisory process of assistive technology in the rehabilitation field as reported in the current scientific literature. DESIGN Systematic literature review. METHODS A systematic literature search was conducted in MEDLINE (2003-2007). In a peer-review process with four independent investigators, studies were selected according to predefined inclusion and exclusion criteria. Because of the poor publication situation, non-research sources were included as well. The data extracted and compared are: information concerning the selection process for assistive technology, whether a client-centred approach is used during the selection procedure, the use of models and instruments, and their compatibility with the ICF. RESULTS The search resulted in 16 papers. None of the studies had an experimental design; nine of the publications were literature reviews. There is a lack of reliable and valid models and instruments for the selection process of assistive technology in the scientific literature. The prevalence of the Matching Person and Technology Model from Scherer (1998) is explicit in the publications. The ICF and ISO 9999 are the only classification systems mentioned in relation to assistive technology, although rarely. CONCLUSION This is a poorly developed field resulting in a lack of evidence-based procedures for AT selection. Such procedures are important to increase consumer satisfaction and the efficiency of AT provision. There is clearly a need for further research in this field.

Abstract
OBJECTIVES To use the World Health Organization's International Classification of Functioning, Disability and Health as a framework to identify and to evaluate wheelchair-specific outcome instruments that are useful for measuring activity and participation. DATA SOURCES CINHAL, PsychInfo, EMBASE, Google Scholar, Dissertation Abstracts Medline databases, and conference proceedings. STUDY SELECTION Activity and participation measures that were specifically intended for adults who use wheelchairs and that were published in English in a peer-reviewed journal were included in this review. Based on electronic database searches using a variety of search terms, articles were identified by title, and appropriate abstracts were retrieved. Articles were obtained for all relevant abstracts. For peer-reviewed measures included in the review, we obtained any instruction manuals and related publications, frequently published in conference proceedings and theses or available electronically, on the development and testing of the measure. DATA EXTRACTION Tools included in the review were evaluated based on their conceptual coverage, reliability, validity, responsiveness, usefulness, and wheelchair contribution, which indicated how well the tool isolated the effect of the wheelchair on activity and participation outcomes. DATA SYNTHESIS A number of conceptual, psychometric, and applicability issues were identified with the 11 wheelchair-specific measures included in the review. A majority of the measures were mobility focused. No single tool received excellent ratings in all areas of the review. Some of the most frequent issues identified included a failure to account for differences attributable to different wheelchairs and wheelchair seating, limited psychometric testing, and high administrative and respondent burden. CONCLUSIONS Good reliability evidence was reported for most of the measures, but validity information was only available for 6 of the 11 measures, and responsiveness information for 3. This review suggests that these measures could be improved with further psychometric testing and with some modification to ensure that the contribution of the wheelchair to activity and participation outcomes is clearly identified.
