Specific Learning Disability is an educational category within special education that identifies an impairment area such as reading, writing, or math despite a student's intelligence. Individualized Education Plan teams address learning disabilities with educational interventions and accommodations. One accommodation for students with a specific learning disability is assistive technology. Occupational therapists need evidence to inform decision-making regarding assistive technology tools to meet the individualized needs of students with learning disabilities. This case report describes how a school-based occupational therapist evaluated one student's assistive technology needs to accommodate her specific learning disability in reading and writing. This evaluation resulted in student-specific and evidence-based recommendations pertinent to age, need, and preferences. Reported outcomes include increased independence with accessing educational materials, increased access to age-appropriate reading material, and increased pleasure reading participation.

Children with physical impairments may have trouble effectively performing the hand movements used in haptic exploration and may miss information about object properties. Assistive robotic systems with haptic feedback may enable children with physical impairments to haptically explore objects. However, it is important to understand if they might be encountering difficulty in assessing object properties with the system. As such, we examined two methods to ascertain a user's uncertainty or stress when doing the exploration, user confidence and electrodermal activity (EDA). Twenty adults and ten children without physical impairments manipulated four pairs of objects to examine size, roughness, hardness and shape. All participants performed the manipulation by controlling a robotic system and by manual exploration in a randomized crossover design. Adults' confidence was lower when using the robotic system and correlated with lower accuracy at determining object properties. Children's responses indicated that they may not have understood how to self-rate confidence. EDA, a potentially objective measure of stress during the task, was actually lower for adults when they used the robotic system, suggesting less physiological arousal than when using their hands. Children's EDA was variable.

New types of wheelchairs are being introduced in the market to maximize opportunities for children to participate in meaningful occupations. However, interventions to support the inclusion of children with mobility limitations by using mobility support are desirable as these children continue to experience barriers to community and school participation, happiness, and inclusion. Little is known about the training programs and interventions designed to effectively integrate wheelchair use into the occupations of children with mobility limitations. This rapid review identified 10 studies addressing programs and interventions to equip children with mobility limitations with wheelchair-related skills and competencies. Three overarching themes, including (1) technology-mediated simulation, (2) custom-made wheelchairs, and (3) skills training and exercises, based on the type of intervention were identified. The development, safety, and playfulness of children with mobility limitations are crucial factors when providing wheelchair-related interventions.

This study translated and culturally adapted the Wheelchair Use Confidence Scale for Manual Wheelchair Users (WheelCon-M) and the Wheelchair Use Confidence Scale for Power Wheelchair Users (WheelCon-P) into Arabic and examined their reliability and validity. Internal consistency and test-retest reliability were examined, and concurrent validity was evaluated using Pearson correlation coefficients with the Arabic versions of the Functioning Everyday with a Wheelchair (FEW) and the Functional Mobility Assessment (FMA). The Arabic translated versions of the WheelCon-M (WheelCon-M-A) and the WheelCon-P (WheelCon-P-A) were administered to 33 adult wheelchair users. Cronbach's α was 0.94 (p < 0.01) for the WheelCon-M-A and 0.95 (p < 0.01) for the WheelCon-P-A. The WheelCon-M-A and WheelCon-P-A were reliable with respect to test-retest with an ICC of 0.974 (p < 0.01) and 0.965 (p < 0.01), respectively. The Pearson correlation coefficient of the WheelCon-M-A scores was 0.776 with the FEW scores and 0.685 with the FMA scores (p < 0.01). The Pearson correlation coefficient of the WheelCon-P-A scores was 0.782 with the FEW scores and 0.654 with the FMA scores (p < 0.01). This study has provided preliminary evidence of new valid, reliable, and useful tools for healthcare professionals to help measure confidence with wheelchair use among Arab wheelchair users.

The Memory Book approach to dementia care effectively fosters daily communication with individuals with dementia. With technological advancements, the traditional memory book intervention has evolved into digital forms. However, it remains unclear whether family caregivers (FCGs) perceive this transition as beneficial or not, especially when their loved ones with dementia demonstrate communicative deficits. To investigate the perceived usefulness of digital memory books, we conducted a survey using the Technology Acceptance Model in which 169 FCGs of individuals with dementia participated. The participants were categorized into two groups based on their observations of communicative deficits in their loved ones. We compared the perceived usefulness of digital memory books between these two groups using Welch's two-sample t-test. Additionally, we employed univariate general linear models to explore the communicative deficits underlying the participants' perceptions. Our findings revealed that FCGs dealing with communicative challenges in their loved ones found digital memory books to be more useful. Furthermore, 7 out of 11 communicative deficits assessed (e.g., anomia) significantly influenced FCGs' perception. The digital memory book intervention has the potential to improve both the quality and quantity of communication between FCGs and individuals with dementia alleviating caregiving burdens for FCGs.

Wayfinding is the process of navigating from one's present location to their desired location. While wayfinding technologies are increasingly used by people with disabilities, there is little understanding of the barriers specific to wayfinding technology. The objective of this study was to understand the wayfinding technology barriers experienced by Canadians with disabilities. A total of 213 participants with varying disabilities (i.e. mobility, visual, hearing, memory and learning disabilities) completed a survey of open-ended questions about their personal experiences with different types of technologies. Technologies were categorized into public (i.e. digital and tactile interfaces) and personalized (i.e. mobile/website applications, wearable devices, smart assistive devices), and qualitative content analysis was used. Main themes were identified and either common across both groups (i.e. compatibility, demands on personal resources, information provision, interactability) or specific to one technology type (i.e. stigma, specific to personalized technology). Detailed subthemes provided greater specificity on the types of barriers encountered. For example, infection risk was noted as a barrier to public technology and high costs was a barrier for personalized technology. Results support the inclusion of wayfinding technology within accessibility standards and provide insights to clinicians on how to best support people with disabilities and their use of technology.

This study aimed to assess the development and usability of the Visually Impaired Masseur Assistance Application (VIMAA) designed to respond to signs of danger or instances of sexual harassment experienced by Visually Impaired Masseurs (VIMs). It harmonizes Rapid Application Development (RAD) method and qualitative in-depth interviews. RAD was implemented with emphasis on four core stages: requirement identification, design workshop, construction, and implementation, while Qualitative in-depth interviews were conducted utilizing thematic analysis for usability testing. Functionality testing also verifies the effectiveness of VIMAA features while requesting help, notification, and feedback. Pre-test identified four themes, including traumatic experiences and the need for protection. Post-test revealed themes such as ease of requesting assistance and switching to speech mode. VIMs perceive that VIMAA as user-friendly, practical, and acceptable. The requesting help, notification, and feedback features also work well. This study presents the effectiveness of VIMAA in establishing a framework that is accessible by a diverse spectrum of VIMs. The insights derived from this research also furnish valuable perspectives on the preferences of users reliant on mobile applications designed for VIMs, thus providing significant impetus for future research and development endeavors in this domain.

This study conducted a secondary analysis to objectively measure the effects of modified ride-on cars (MROCs) training in different postures on physical activity (PA) levels in children with motor delays. Data from 39 participants were analyzed in a randomized controlled trial. The participants included those using MROC in standing postures (n = 11, mean age = 22.87 months), MROC in sitting postures (n = 16, mean age = 19.53 months), and a control group that received conventional therapy (n = 12, mean age = 23.30 months). PA intensity was measured using an ActiGraph GT3X on the participants' wrists and right hip at weeks 1, 6, and 12 of the 12-week intervention period. This trial was registered at ClinicalTrials.gov (NCT02527356). The demographic data were similar across the groups. No significant differences were found in the interaction, group, or time effects for any of the positions (p > 0.05). The PA levels were consistent in at least light PA intensity range. MROC training may yield PA levels comparable to those of conventional therapy. Variations in activity and motor impairment severity could affect outcomes. Future studies should investigate factors such as task characteristics, motor delay severity, PA cutoff points, and training dosage that may influence PA intensity.

Augmentative and alternative communication (AAC) supports offer communication aids for individuals with severe speech and physical impairments. This study presents the development and proof of concept for an iPad application designed to evaluate the design preferences of both adults and children for AAC scanning and emerging P300-brain-computer interface access to AAC (BCI-AAC), both of which utilize item highlighting. Developed through a multidisciplinary and iterative process, the application incorporates customizable highlighting methods and display options for spelling-based and pictorial symbol interfaces. Initial testing involved five participants, including two adults with physical impairments and three children without physical impairments. Participants created unique interface displays using picture overlays, motion, and other highlighting methods. Feedback indicated strong usability and enjoyment during application use. Recommendations included expanded sound options and pre-made templates. This study demonstrates preliminary proof of concept for the application and supports the need for further research to explore user preferences and optimize communication outcomes across various AAC modalities. While BCI-AAC technology remains in its early stages, its integration into this application helps promote user-centered BCI-AAC development.

Visually impaired individuals actively utilize devices like computers, tablets, and smartphones, due to advancements in screen reader technologies. Integrating freely available deep learning models, image captioning can further enhance these readers, providing an affordable assistive tech solution. This research outlines the critical software requirements necessary for image captioning tools to effectively serve this demographic. Two qualitative investigations were conducted to determine these requirements. An online survey was first conducted to identify the main preferences of visually impaired users in relation to audio descriptive software, with findings visualized using word clouds. A subsequent study evaluated the proficiency of existing deep learning captioning models in addressing these stipulated requirements. Emphasizing the need for comprehensive image data, the results highlighted three primary areas: 1) characteristics of individuals, 2) color specifics of objects, and 3) the overall context of images. The research indicates that current captioning tools are not entirely effective for the visually impaired. Based on the delineated requirements and suggested future research paths, there is potential for the development of improved image captioning systems, advancing digital accessibility for the visually impaired.
