Background: The purpose of this study was to provide empirical evidence on knowledge gaps in wheelchair skills, emerging technology, and preferred sources to find information about mobility assistive technologies (MAT) among Saudi mobility device users. Method: A previously developed English-language survey used in a previous pilot study was translated into Arabic and culturally adapted for MAT users within Saudi Arabia. This study followed Beaton guidelines for translating and performing cultural adaptation. A cross-sectional study was conducted anonymously to gather opinions of Saudis with disabilities who use MAT. The Arabic version was administered online using the Pitt-licensed version of the Qualtrics software. Referral sampling technique was used for recruiting, and the data from a sample of (N=353) are represented. Results: The overall face validity (FVI) for clarity and comprehension was 0.85, indicating that the Arabic Version was simple, easy to understand, and relevant for Saudi Arabian culture. The average age of respondents was approximately 39 (SD 9.6) years, and most had used their mobility devices for two to five years (N=164, 46.5%). Spinal cord injury (SCI) was the largest diagnostic group (N=141, 40%). Respondents reported gaps in knowledge about both manual wheelchair and power wheelchair skills. Physical therapists and/or occupational therapists, the internet, social media, physicians, and family and friends using AT were reported as the most frequent sources used to find information about mobility devices (85.6%. 72.8%, 60.3%, 48.2%, and 45%) respectfully. Conclusion: The survey findings revealed some gaps in knowledge among Saudi MAT consumers with respect to wheelchair skills and emerging technologies, suggesting a more knowledge translation research is needed in this area.

Despite the increasing use of assistive mobility devices, practical education to navigate real-world ground transportation barriers is lacking. The educational board game, called HERL-Town, was developed to teach safe and effective navigation for mobility device users (MDUs) in the community. The study examined the initial validity, reliability, and overall quality of HERL-Town as an educational tool for overcoming transportation barriers in real-world environments. HERL-Town featured fifty scenarios focused on transportation barriers and strategies, which were assessed for content validity, while the game quality was evaluated using the Model for the Evaluation of Educational Games (MEEGA+) tool. Twenty-three experienced MDUs and four caregivers participated in the study. The results indicated a good quality score of 60.15 and forty-five scenarios met the content validity standards. The overall reliability of the scenarios was moderate (ICC = 0.729). Early psychometric findings suggest HERL-Town as a promising effective educational game for helping new MDUs and their travel companions navigate safe and effective ground transportation barriers, hence enhancing their confidence, independence, and participation in the community.

Objectives: Wheelchair transfers risk injury to users and caregivers. Conventional transfer devices are injury-prone and time inefficient. The Powered Personal Transfer System (PPTS), utilizing a modified Electric Powered Wheelchair (EPW) and a hospital bed, provides a no-lift solution for bed-to-wheelchair transfers. Objective 1: Assess PPTS workload compared to existing methods. Objective 2: Evaluate PPTS EPW in daily mobility tasks. Objective 3: Perform Rehabilitation Engineering and Assistive Technology Society of North America (RESNA) wheelchair standards testing for PPTS EPW stability and performance. Methods: Fifteen professional and family caregivers, experienced in assisting EPW users, performed transfers between the bed and EPW using the PPTS. Subsequently, participants drove the PPTS EPW providing ratings on the ease of performing mobility tasks. Wheelchair testing was conducted following RESNA standards. Setting: : Simulated bedroom in a laboratory setting. Results: Participants reported low workload demands for employing the PPTS and indicated a preference for the PPTS over existing transfer devices/methods. Ease of performing everyday mobility tasks was not significantly different between the modified PPTS and the commercially available original manufacturer equipment EPW (p > 0.05). RESNA wheelchair standards testing confirmed that the PPTS EPW preserves functionality, stability and performance when compared to similar commercially available EPWs. Conclusion: The PPTS demonstrated promise in offering a practical, low demanding, and safe solution for transfers. It has the potential to enhance user and caregiver safety by reducing the incidence of caregiver injuries associated with assisting in transfer tasks. In addition to its efficiency and ease of use, it is an advancement in assistive technology for wheelchair transfers.

Despite advances in wearable robots across various fields, there is no consensus definition or design framework for the application of this technology in rehabilitation or musculoskeletal (MSK) injury prevention. This paper aims to define wearable robots and explore their applications and challenges for military rehabilitation and force protection for MSK injury prevention. We conducted a modified Delphi method, including a steering group and 14 panelists with 10+ years of expertise in wearable robots. Panelists presented current wearable robots currently in use or in development for rehabilitation or assistance use in the military workforce and healthcare. The steering group and panelists met to obtain a consensus on the wearable robot definition applicable for rehabilitation or primary injury prevention. Panelists unanimously agreed that wearable robots can be grouped into three main applications, as follows: (1) primary and secondary MSK injury prevention, (2) enhancement of military activities and tasks, and (3) rehabilitation and reintegration. Each application was presented within the context of its target population and state-of-the-art technology currently in use or under development. Capturing expert opinions, this study defines wearable robots for military rehabilitation and MSK injury prevention, identifies health outcomes and assessment tools, and outlines design requirements for future advancements.

Context/objective: Hard-shell toilet seats may compromise safety and hinder the participation of individuals at risk for pressure injuries (PIs) when using these facilities away from home in public, hotel, or family/friend restrooms. Moreover, people often add "wash-cloths" for additional padding for comfort, and to reduce the risk of PIs due to pressure or shearing on their wheelchairs surfaces. This study investigated the utilization of portable pads, initially designed for toilet use but adaptable to various places and contexts, while examining pad usability. Design: A cross-sectional descriptive survey design. Setting: Inpatient care, outpatient care, and community setting. Participants: 45 individuals at risk of PIs. Results: Participants extended the use of these pads beyond toilets, employing them as wheelchair armrest and leg rest pads in other settings. Feedback from a customized questionnaire indicated high levels of usefulness (8.5/10) and ease of use (9.1/10) attributed to the pads. Among the features, the top three favored were ease of use, comfort/cushioning, and function. Participants expressed a desire for a variety of sizes and colors to enable versatile usage and suggested incorporating a pocket for storing small items. Conclusions and relevance: Individuals at risk of PIs require cushioning not only on hard-shell toilet seats, but also for additional padding, protection and enhancing the use of wheelchairs. Rehabilitation professionals can play a crucial role in educating and training both clients and caregivers to understand PI prevention, enabling them to effectively leverage the pads in appropriate situations, thereby enhancing their comfort in their wheelchairs during social engagement.

Informal caregivers often provide transfer assistance to individuals with disabilities; however, repeated transfers are associated with a high risk of musculoskeletal pain and injury, and training and education around transfers is minimal. The purpose of this study was to develop and assess the content validity of a new tool, the Caregiver Assisted Transfer Technique Instrument (CATT), which could be used to provide an objective indicator of transfer performance. Item importance, clarity, and appropriateness of responses were rated on a five-point Likert scale by clinicians (n = 15), informal caregivers (n = 10), and individuals with spinal cord injury (n = 5). The content validity index and modified Kappa of each item was calculated. Participants also provided qualitative feedback on item content. In general, items were rated favorably for their importance (4.47 to 5.00), clarity (4.33 to 4.90), and appropriateness of responses (4.38 to 4.90), and most items had excellent content validity (k* ≥ 0.75). Feedback from participants led to the creation of two versions of the CATT: one for manual lifting techniques (CATT-M) and one for transfers performed via lift-based technologies (CATT-L). Future work will focus on establishing the reliability and validity of the CATT as well as developing training and education interventions surrounding assisted transfers.

Objective This study aims to enhance the accessibility and quality of mobility assistive technology (MAT) by investigating and bridging knowledge gaps between MAT providers and consumers with ambulatory limitations. Design A survey was conducted among MAT providers in the United States, consisting of sections on awareness, knowledge importance and desire, and knowledge sources. The responses were compared to data collected from consumers in a previous study. Results A total of 144 MAT providers participated, with 60% having received academic or professional training in relevant fields. Analysis revealed significant knowledge gaps between providers and consumers, particularly in AT assessment tools and knowledge sources. Moderate gaps were also observed in areas such as clinical practice guidelines, desired MAT information, and knowledge sources. However, the gaps in other areas were relatively small. Conclusion This study highlights the knowledge gaps between MAT providers and consumers, hindering the optimal utilization and fulfillment of user needs. Providers possess valuable information that consumers may lack, positioning them as primary knowledge sources. Addressing these gaps through targeted interventions, improved communication channels, and enhanced education can enhance the utilization of MAT and improve outcomes for individuals with ambulatory limitations.

Objective The purpose of this study was to further previous research and gather additional information regarding the usage of motorized shopping scooters as well as feedback for improvements to an air-powered scooter. Methods Online surveys were used to assess individuals’ shopping characteristics and experience using the motorized scooters and to gather feedback from store employees regarding their experience. K-Means clustering analysis was used to determine user demographics who chose to use the air-powered scooter versus the electric powered scooter while shopping. Results A total of 127 individuals provided informed consent, 65 individuals from Site 1 and 62 individuals from Site 2. 120 participants met the inclusion criteria and completed the survey. K-Means clustering found that age, type of personal mobility device, shopping bill total, and frequency using a motorized shopping scooter to be significant factors in whether individuals chose to use an air-powered scooter or electric-powered scooter. Conclusion Motorized shopping scooters are in high demand and used by a wide variety of individuals, yet electric-powered scooters are commonly unavailable due to having dead batteries or all the devices being in use. Air-powered scooters may serve as a practical replacement for the current electric-powered scooters found in grocery and retail stores.
