Disabil Rehabil Assist Technol 2024; 19:745-753. [PMID: 36107814 DOI: 10.1080/17483107.2022.2121008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2021] [Revised: 08/28/2022] [Accepted: 08/31/2022] [Indexed: 10/14/2022]
Abstract
PURPOSE With an ageing population, the use of mobility scooters by community-dwelling older adults with mobility limitations has been increasingly prevalent in Singapore. Their experiences in using mobility scooters remain unclear. This study aimed to explore the impact of mobility scooters on occupational performance and engagement among elderly Singaporeans. MATERIALS AND METHODS Mobility scooter users were recruited via purposive and snowballing sampling. Semi-structured interviews were conducted in English or Mandarin via phone call or face-to-face and audio-recorded with permission. Interviews were transcribed verbatim in their original language and translated to English (when applicable) for thematic analysis. RESULTS Twelve eligible participants (mean age: 75 years) completed the interviews. They were predominantly female Chinese with 7 receiving training from occupational therapists (OT). Four main themes emerged from the interviews describing their experiences of using mobility scooters: factors of decision-making in getting a mobility scooter, enhanced occupational participation with the use of the mobility scooter, enablers for community participation and barriers to community participation. Despite having barriers, older adults with mobility limitations generally still had positive experiences to continue using mobility scooters to perform occupations in the community. CONCLUSIONS This study highlights the benefits of mobility scooters in supporting users' occupational performance and engagement in the community. Continual efforts are required from all stakeholders to provide an accessible environment and improve societal attitudes to further support the mobility scooter users.IMPLICATIONS FOR REHABILITATIONMobility scooter users can be deterred from performing their preferred occupations if they had a prior negative encounter and they mainly rely on self-developed coping strategies to overcome possible barriers in the community.Occupational therapists should identify and address the potential barriers when prescribing mobility scooters to older adult users.Occupational therapists should work collaboratively with other key stakeholders, such as external vendors and government agencies, to co-create a universal guideline to support and safeguard mobility scooter users.

Abstract
PURPOSE Rehabilitation professionals prescribe patients with suitable powered mobility aids (PMAs) based on patient characteristics, e.g., age and mobility. However, there is paucity of literature examining patient characteristics associated with PMA types in Asian contexts. This research aims to study (i) characteristics of Singapore PMA users and (ii) correlations between characteristics and two PMA types - motorised wheelchairs and powered scooters. It is hypothesised that patients' age, mobility status and medical conditions have correlations with PMA types. METHODOLOGY A cross-sectional, retrospective study design was used to investigate characteristics of patients (age ≥ 21 years) at Tan Tock Seng Hospital Occupational Therapy Seating Clinic between 2017 and 2019. Comparisons of proportions of motorised wheelchair users versus powered scooter users based on characteristics were analysed using Chi-square test. Subsequently, statistically significant patient characteristics were selected for a multiple logistic regression. RESULTS Among 352 patients, 21% and 79% were prescribed motorised wheelchairs and powered scooters, respectively. Patients aged 61-90 years were twice those aged 21-60 years. Males were double of females. Patients of (i) an older age, (ii) more ambulant, (iii) independent in transfers and (iv) in activities of daily living (ADLs), were more likely powered scooter users. Conversely, patients of (i) a younger age, (ii) less ambulant, (iii) require assistance in transfers and (iv) in ADLs were more likely motorised wheelchair users. Patients' gender and caregiver status showed no statistically significant correlations with PMA types. CONCLUSIONS Rehabilitation professionals could consider patients' age, mobility status, transfer status and ADL status when prescribing PMA for Asian populations.Implications for rehabilitationGuide rehabilitation professionals in making clinical decisions on the type of powered mobility aid (PMA) to prescribe based on patients' characteristics.Aid in the development of future guidelines for rehabilitation professionals in prescription of PMAs.

Abstract
There is a growing concern regarding the driving safety of Motorized Mobility Scooters (MMSs) for the elderly and mobility-impaired individuals. Although various research has made progress in sensor-based driving assistance systems to identify environmental hazards, few studies focus on investigating the impact of user behavior on MMS driving. In this paper, a driving status logging (DSL) system is developed to measure the user's behavior while driving. A cross-correlation analysis is implemented to quantify the temporal relationship between the head movement and steering operation in the driving of MMSs. The preliminary results suggest that the head movement can be used as an appropriate index to predict the intended steering operation in the driving of MMSs. Moreover, the quantified head-steering lag time provides the possibility to identify the hazardous driving pattern of MMS users.Clinical Relevance- The investigation of user behavior has the potential to improve the safety of MMSs. In this study, the user behavior in the driving of MMSs was quantitatively measured using the developed DSL system. Consequently, the temporal relationship between head movement and steering operation was first quantified in MMS-related research. These outcomes provide valuable insights into developing behavioral interventions to address the user's risky behavior patterns, thereby promoting the driving safety of MMSs.

Estimation of Steering and Throttle Angles of a Motorized Mobility Scooter with Inertial Measurement Units for Continuous Quantification of Driving Operation.

Abstract
With the growing demand from elderly persons for alternative mobility solutions, motorized mobility scooters (MMSs) have been gaining importance as an essential assistive technology to aid independent living in local communities. The increased use of MMSs, however, has raised safety issues during driving and magnified the necessity to evaluate and improve user driving skills. This study is intended to develop a novel quantitative monitoring method for MMS driving operation using inertial measurement units (IMUs). The proposed method used coordinate transformations around the rotational axes of the steering wheel and the throttle lever to estimate the steering and throttle operating angles based on gravitational accelerations measured by IMUs. Consequently, these operating angles can be monitored simply using an IMU attached to the throttle lever. Validation experiments with a test MMS in the stationary state confirmed the consistency of the proposed coordinate transformation with the MMS's geometrical structure. The driving test also demonstrated that the operating angles were estimated correctly on various terrains and that the effects of terrain inclination were compensated using an additional IMU attached to the scooter body. This method will be applicable to the quantitative monitoring of driving behavior and act as a complementary tool for the existing skills' evaluation methods.

Abstract
OBJECTIVE As a result of an aging population, mobility scooter use is increasing in Western countries. Consequently, an increase in mobility scooter-related injuries (MSRIs) is observed. Yet there is a paucity of studies in the literature assessing MSRIs. The purpose of this study was to investigate mechanism, severity, and localization of injury of MSRIs in the emergency department (ED) of a Dutch level 2 trauma center over a 9-year period. METHODS This was a retrospective study of MSRIs in the ED of a teaching hospital in the Netherlands between January 2010 and December 2019. All patients with an MSRI were included, as long as they were the driver of the vehicle. Data were collected from electronic patient files. The primary outcomes were severity of injury, defined by the Abbreviated Injury Scale (AIS) and Injury Severity Score (ISS), and mechanism and localization of injury. RESULTS A total of 382 patients were identified. Of these, 208 (54.3%) were female and the median age was 76 years (interquartile range [IQR] = 67.0-83.0). The median Charlson Comorbidity Index (CCI) was 5.0 (IQR = 4.0-6.0). Three (0.8%) patients had an ISS ≥ 16. The median ISS was 3.0 (IQR = 1.0-5.0). The lower extremity was the most commonly injured body region (46.5%), followed by head injury (36.3%), external injury (31.6%), and upper extremity injuries. Fractures were most commonly observed in the shoulder (10.2%), hip (8.9%), and ankle (6.3%). Most crashes were single-vehicle accidents (87.2%) and the most common mechanism of injury was rollover of mobility scooter (49.3%). Almost half of the patients (44.1%) had a fracture and the admission rate was 28.2% with a median length of stay (LOS) of 10 days. Fifty (13.1%) patients required surgery, of which 58% were hip repair surgery. CONCLUSION In this cohort of MSRIs, mobility scooter users had a median age of 76 years and severe comorbidity was common. Based on ISS, patients had a mild injury profile. However, the relatively high admission and surgery rates reflect the potential serious consequences of MSRIs and the obvious vulnerability of this population.

Abstract
Globally, the walker is one of the most common assistive technologies used by older adults with mobility impairments, which is also the case in New Zealand. However, there is a scarcity of knowledge regarding their specific requirements in housing design. Adopting an ethnographic approach, the perceptions and spatial use of 16 older adults who used a walker were investigated as part of a larger study on quality of life and housing design. Five emergent themes for walker user perception and spatial use were identified, from which design considerations were distilled and then categorised into 10 design elements. The study highlights differences between the requirements for accommodating walkers and those for accommodating wheelchair users. It provides new insights into improved housing design for older adults, which have the potential to be incorporated into existing frameworks for accessible design and universal design thereby improving the independence and safety of older adults.

Abstract
Background By 2030, the global population of people older than 60 years is expected to be higher than the number of children under 10 years, resulting in major health and social care system implications worldwide. Without a supportive environment, whether social or built, diminished functional ability may arise in older people. Functional ability comprises an individual's intrinsic capacity and people's interaction with their environment enabling them to be and do what they value. Objectives This evidence and gap map aims to identify primary studies and systematic reviews of health and social support services as well as assistive devices designed to support functional ability among older adults living at home or in other places of residence. Search Methods We systematically searched from inception to August 2018 in: MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, CENTRAL, CINAHL, PsycINFO, AgeLine, Campbell Library, ASSIA, Social Science Citation Index and Social Policy & Practice. We conducted a focused search for grey literature and protocols of studies (e.g., ProQuest Theses and Dissertation Global, conference abstract databases, Help Age, PROSPERO, Cochrane and Campbell libraries and ClinicalTrials.gov). Selection Criteria Screening and data extraction were performed independently in duplicate according to our intervention and outcome framework. We included completed and on-going systematic reviews and randomized controlled trials of effectiveness on health and social support services provided at home, assistive products and technology for personal indoor and outdoor mobility and transportation as well as design, construction and building products and technology of buildings for private use such as wheelchairs, and ramps. Data Collection and Analysis We coded interventions and outcomes, and the number of studies that assessed health inequities across equity factors. We mapped outcomes based on the International Classification of Function, Disability and Health (ICF) adapted categories: intrinsic capacities (body function and structures) and functional abilities (activities). We assessed methodological quality of systematic reviews using the AMSTAR II checklist. Main Results After de-duplication, 10,783 records were screened. The map includes 548 studies (120 systematic reviews and 428 randomized controlled trials). Interventions and outcomes were classified using domains from the International Classification of Function, Disability and Health (ICF) framework. Most systematic reviews (n = 71, 59%) were rated low or critically low for methodological quality.The most common interventions were home-based rehabilitation for older adults (n = 276) and home-based health services for disease prevention (n = 233), mostly delivered by visiting healthcare professionals (n = 474). There was a relative paucity of studies on personal mobility, building adaptations, family support, personal support and befriending or friendly visits. The most measured intrinsic capacity domains were mental function (n = 269) and neuromusculoskeletal function (n = 164). The most measured outcomes for functional ability were basic needs (n = 277) and mobility (n = 160). There were few studies which evaluated outcome domains of social participation, financial security, ability to maintain relationships and communication.There was a lack of studies in low- and middle-income countries (LMICs) and a gap in the assessment of health equity issues. Authors' Conclusions There is substantial evidence for interventions to promote functional ability in older adults at home including mostly home-based rehabilitation for older adults and home-based health services for disease prevention. Remotely delivered home-based services are of greater importance to policy-makers and practitioners in the context of the COVID-19 pandemic. This map of studies published prior to the pandemic provides an initial resource to identify relevant home-based services which may be of interest for policy-makers and practitioners, such as home-based rehabilitation and social support, although these interventions would likely require further adaptation for online delivery during the COVID-19 pandemic. There is a need to strengthen assessment of social support and mobility interventions and outcomes related to making decisions, building relationships, financial security, and communication in future studies. More studies are needed to assess LMIC contexts and health equity issues.

Abstract
For people with disabilities or chronic diseases, an electrically supported tricycle (e-trike) could facilitate independence and participation in physical activity, and improve health conditions. This study investigates the exercise intensity and perceived exertion of e-trike cycling. Twenty healthy participants cycled on an e-trike with different speeds (12 and 18 km/h) and different levels of electric pedal support at an outdoor athletics track. Exercise intensity was measured with oxygen consumption (V˙O2) using a Cosmed K4B2 analysis unit, perceived exertion was measured with the Borg Rating of Perceived Exertion scale, pedaling power, and engine power were measured with a torque sensor. The effect of speed and support was analyzed with a Linear Mixed Effects model. V˙O2 was 18.67 ± 3.13 ml/kg/min without support, with electric support the exercise intensity was significantly below moderate intensity (i.e. 10.5 ml/kg/min) at t = 11.37, p < .001, 95% CI: 1.90, 2.77. The Borg score without support was 9.79 ± 1.72 and all other conditions below this, which were significantly below moderate intensity (i.e. 11) at t = -3.07, p = .007, 95% CI: -2.04, -0.38. Speed and support significantly affected V˙O2 (F = 185.49, p < .001). E-trike cycling is a low intensity activity, but intensity can be influenced by changing speed and support level.

Abstract
INTRODUCTION As our society ages, mobility scooters are a fast-growing mode of transportation. The growing prevalence of mobility scooters as a mode of transportation has the potential to not only affect the lives of older adults who use them but to impact urban environments at large as well as have implications for the safety of pedestrians and of other vehicle users. GOAL The goal of this paper is to explore the gaps in the existing literature regarding mobility scooters, laying out key areas for future research. RESULTS We propose three areas of research that focus on mobility scooter use by older people: (1) research involving users - impacts on older people employing mobility scooters; (2) studying the impact on urban space - public spaces and passageways used as travel routes, the barriers impeding travel and lack of appropriate parking solutions in the urban environment; and (3) issues of safety - mobility scooter driving and travel regulations and infrastructure design regulations. DISCUSSION Addressing these gaps in knowledge has the potential to contribute to the social and physical sustainability of future urban environments as well as to the wellbeing of older adults.

Abstract
Cities are constantly transforming and, consequently, attracting efforts from researchers and opportunities to the industry. New transportation systems are being built in order to meet sustainability and efficiency criteria, as well as being adapted to the current possibilities. Moreover, citizens are becoming aware about the power and possibilities provided by the current generation of autonomous devices. In this sense, this paper presents and discusses state-of-the-art transportation technologies and systems, highlighting the advances that the concepts of Internet of Things and Value are providing. Decentralized technologies, such as blockchain, are been extensively investigated by the industry, however, its widespread adoption in cities is still desirable. Aligned with operations research opportunities, this paper identifies different points in which cities’ services could move to. This also study comments about different combinatorial optimization problems that might be useful and important for an efficient evolution of our cities. By considering different perspectives, didactic examples are presented with a main focus on motivating decision makers to balance citizens, investors and industry goals and wishes.

Abstract
Objective: Powered mobility devices (PMDs) are commonly used as aids for older people and people with disabilities, subgroups of vulnarable road users (VRUs) who are rarely noted in traffic safety contexts. However, the problem of accidents involving PMD drivers has been reported in many countries where these vehicles have become increasingly popular. The aim of this study is to extract and analyze national PMD-related accident and injury data reported to the Swedish Traffic Accident Data Acquisition (STRADA) database. The results will provide valuable insight into the risks and obstacles that PMD drivers are exposed to in the traffic environment and may contribute to improving the mobility of this group in the long term. Methods: The current study is based on data from 743 accidents and 998 persons. An analysis was performed on a subset of data (N = 301) in order to investigate the development of accidents over a period of 10 years. Thereafter, each accident in the whole data set was registered as either single (N = 427) or collision (N = 315). Results: The results show that there was a 3-fold increase in the number of PMD-related accidents reported to STRADA during the period 2007-2016. With regard to single accidents, collisions, as well as fatalities, the injury statistics were dominated by males. Single accidents were more common than collisions (N = 427 and N = 316, respectively) and the level of injury sustained in each type of accident is on par. The vast majority of single accidents resulted in the PMD driver impacting the ground (87%), due to either PMD turnover (71%) or the driver falling out of the PMD (16%). The reason for many of the single accidents was a difference in ground level (34%, typically a curb). Cars, trucks, or buses were involved in 67% of collision events; these occured predominantly at junctions or intersections (70%). Abbreviated Injury Scale (AIS) 3+ injuries were dominated by hip and head injuries in both single accidents and collision events. Conclusions: The present study shows that further research on PMD accidents is required, with regard to both single accidents and collision events. To ensure that appropriate decisions are made, future work should follow up on injury trends and further improve the quality of PDM-related accident data. Improved vehicle stability and design, increased usage of safety equipment, proper training programs, effective maintenance services, and development of a supporting infrastructure would contribute to increased safety for PMD drivers.

Abstract
Purpose: This cohort study investigated changes in physical activity, community mobility and social participation following the first-time purchase of a mobility scooter.Methods: A national sample of persons aged 65+ years was surveyed using customized semi-structured interviews that explored changes in physical activity via the International Physical Activity Questionnaire modified for the elderly, and community involvement. Participants were recruited at the point of purchase of their first mobility scooter, and interviewed at this time and again at 2 and 6 months post-purchase.Results: Eighteen participants (F = 10, M = 8) aged between 65 and 95 years were recruited. Physical activity levels remained unchanged in 12 participants, and declined by at least one category in five participants. All participants reported improvement to their self-perceived quality of life following acquisition of a mobility scooter. Participants did not access additional forms of physical activity, though nine reported increased social participation. At baseline, five participants stated that the scooter was used for journeys they formerly made by other motorized transport, and by the 6-month interview, this number had risen to 15 participants.Conclusions: It is unlikely that changes in physical activity were related to the ageing process given the relatively short time span of the study. Thus it can be inferred that participants viewed their mobility scooter as a vehicle for maintaining their lifestyle rather than as a means to seek out additional activities. Improvements to perceived quality of life may be attributed to continuing or furthering community and social engagement, and a sense of retained independence.Implications for rehabilitationAn awareness of possible changes in physical activity associated with the purchase of a mobility scooter is needed.The purchase of a mobility scooter provides a viable means of transport to facilitate access to physical activity situations.Over-reliance on a mobility scooter has the potential to decrease health-related physical activity.The development and dissemination of a targeted health message about maintaining (or improving) physical activity levels is warranted to increase the awareness in this growing group of new, and current, mobility scooter riders in an increasingly ageing population.

Abstract
Purpose: Older people experiencing a decline in their mobility often choose to use a mobility scooter. They are used by those with mobility impairments to enable them to travel independently and engage in activities outside the home. This project explored the perceptions of mobility scooters by older adults who experience mobility difficulties but do not use mobility scooters. It aimed to understand how scooters were perceived by this group to uncover any barriers to scooter use and to help in predicting future uptake. Materials & Methods: Semi-structured interviews were carried out to enable the elicitation of attitudes and perceptions about mobility decline and mobility scooters. All the interviewees were classified as preclinically disabled so that they had some mobility limitations that would indicate that a mobility scooter could be beneficial to increase their mobility. Results: Non-mobility scooter user are wary of scooter users due to negative experiences interacting with them. Potential personal scooter uptake is viewed with great reluctance and as an indication that they themselves have given up. Conclusions: Older adults with mobility impairments could benefit from using a mobility scooter by gaining an improved quality of life, engagement and social relationships. However the wish to disassociate oneself with ageing or physically decline means that large proportions of this population are unwilling to. Implications for rehabilitation Mobility scooter use can aid those with restricted mobility to increase their independence and quality of life. Stigmatization of and previous negative interaction with mobility scooter users discourage potential users from utilizing them.

Abstract
Purpose: Older adults with low vision are a growing population with rehabilitation needs including support with community mobility to enable community participation. Some older adults with low vision choose to use mobility scooters to mobilize within their community, but there is limited research about the use by people with low vision. This paper describes a pilot study and asks the question: what are the experiences of persons with low vision who use mobility scooters? Methods: This study gathered the experiences of four participants with low vision, aged 51 and over, who regularly use mobility scooters. Diverse methods were used including a go-along, a semi-structured interview and a new measure of functional vision for mobility called the vision-related outcomes in orientation and mobility (VROOM). Findings: Four themes were found to describe experiences: autonomy and well-being, accessibility, community interactions and self-regulation. Discussion and implications: This study was a pilot for a larger study examining self-regulation in scooter users. However, as roles emerge for health professionals and scooters, the findings also provide evidence to inform practice, because it demonstrates the complex meaning and influences on performance involved in low vision mobility scooter use. Implications for rehabilitation Scooter use supports autonomy and well-being and community connections for individuals with both mobility and visual impairments. Low vision scooter users demonstrate self-regulation of their scooter use to manage both their visual and environmental limitations. Issues of accessibility experienced by this sample affect a wider community of footpath users, emphasizing the need for councils to address inadequate infrastructure. Rehabilitators can support their low vision clients' scooter use by acknowledging issues of accessibility and promoting self-regulation strategies to manage risks and barriers.

Abstract
PURPOSE To investigate user satisfaction with characteristics of powered scooters (scooters), frequency of use, and factors predicting daily scooter use. DESIGN Cross-sectional. SAMPLE Adult scooter users (n = 59) in Denmark and Norway, mean age 74.5 (standard deviation 12.3) years. METHODS Structured face-to-face interviews. The NOMO 1.0, the Quebec User Evaluation of Satisfaction with assistive devices (QUEST 2.0), and a study specific instrument were used to collect data. Descriptive statistics were applied, and regression analyzes were used to investigate predictors for daily scooter use. The International Classification of Functioning, Disability and Health (ICF) served as a framework for classifying variables and guiding the investigation. RESULTS Satisfaction with the scooter characteristics was high with most participants being very satisfied or quite satisfied (66.1-91.5%). Most scooters were used daily (36.2%) or several times a week (50.0%). User satisfaction with safety of the scooter [odds ratio (OR) = 11.76, confidence interval (CI) = 1.70-81.28] and reduced balance (OR = 5.63, CI = 0.90-35.39) increased the likelihood of daily use, while reduced function in back and/or legs (OR = .04, CI = 0.00-0.75), tiredness (OR = .06, CI = 0.01-0.51), and increased age (OR = .93, CI = 0.87-1.00) reduced the likelihood of daily use. 52.8% of the variance was explained by these variables. CONCLUSIONS User satisfaction was high, and most scooters were used frequently. User satisfaction with safety, specific functional limitations and age were predictors for daily scooter use. Implications for Rehabilitation Scooters seem to be a beneficial intervention for people with mobility impairment: user satisfaction and frequency of use are high. Users' subjective feeling of safety should be secured in the service delivery process in order to support safe and frequent scooter use. Training of scooter skills should be considered in the service delivery process.
