Congenital limb defects occur when a limb does not develop normally during pregnancy. The quality of each person's everyday life is significantly impacted by any of these defects and there is no concrete treatment. 3D modeling and printing, enables the creation and customization of precise virtual and/or physical models, including models of the human anatomy. These technologies provide a novel method of producing new devices with optimized design and production time, improving adaptability, and incorporating functionality. To this end, we propose a method of designing and producing 3D printed assistive devices and we also present an example of an assistive device, done in the 3D Printing Center for Health, as well as its impact on the patient's daily life. With this device, the patient became able to play the guitar and hold a knife, thus helping on these two activities.

The purpose of this study was to 1) identify and describe the population seeking alternative and augmentative communication (AAC) evaluations at an assistive technology (AT) center in the Midwestern United States and 2) describe the AAC device features or services participants identify as most important at their initial AAC evaluations. Charts of 53 participants seeking AAC interventions at an AT center in the Midwestern United States were retrospectively reviewed. Information from the QUEST 2.0 was used to determine what AT features were identified as most important. The majority of participants seen at the AT center had progressive diseases. Across all of the participants, ease of use and effectiveness were identified as the "most important" aspects of an AAC device satisfaction. These findings highlight the importance of determining who is accessing AAC services across AT centers to determine whether barriers to AAC services exist. Moreover, patients report regarding what variables they deem as most important reflect the fact that excellent service-delivery may not overcome the importance of other variables, such as ease of use that impact AAC use.

Many students have difficulty in mastering syntax when programming. To alleviate this problem, the Scratch programming language was developed to have a visual block-based drag and drop code editor, where the shapes of the blocks and animation are used to make the syntax intuitive. To similarly make syntax intuitive to individuals who are blind or visually impaired (BVI) using tangible code blocks, a method needs to take into account perceptual processing differences between the senses and implementation differences between the physical and virtual world. The studies in this paper examined the effectiveness of using localized reciprocal shape information in combination with magnetic attraction for providing intuitive feedback about syntax. Supplementing the use of localized reciprocal shape constraints with magnetic attraction increased the accuracy and perceived ease of use by blindfolded BVI users to detect whether blocks successfully connected and, therefore, represented a code segment with valid syntax. This did not appear to change significantly with changes in the size and weight of the blocks, although stronger magnetic connections appeared preferred. We also introduced a "stopper" design to allow for code blocks to have exceptions to the regular syntax rules, while not adding complexity to the majority of code blocks.

While wheelchair skills training has demonstrated highly effective outcomes for wheelchair users, prevalence of receiving comprehensive skills training is low. Studies demonstrate a wheelchair skills "bootcamp" significantly improves occupational therapy students' capacity to demonstrate wheelchair skill performance; however, how bootcamps impact students' self-efficacy to deliver skills training in future clinical practice is unclear. This study explored a large dataset collected from nine successive student cohorts attending a structured wheelchair skills bootcamp at a single site. Bootcamps were 4-4.5 hours in duration and content was based on the Wheelchair Skills Program. Mean improvement in skill capacity was 34.8% (95% CI 33.5; 36.1) and wheelchair self-efficacy improved by 28.7% (95% CI 27.3; 30.1). Post-bootcamp self-efficacy scores for Assessment (80.9%), Training (78.5%), Spotting (87.4%), and Documentation (70.4%) all improved by 30-40%. Mandatory bootcamps had lower baseline scores but similar post-bootcamp and change scores as voluntary ones. Cohorts during the COVID-19 pandemic had significantly lower baseline scores for wheelchair skill capacity and confidence as well as self-efficacy with assessment, but significantly larger improvements post-bootcamp. An experiential bootcamp is effective across a wide range of occupational therapy student cohorts in preparing them to deliver wheelchair skills training in future clinical practice.

Crutches are the most prescribed ambulatory assistive device and are used for mobility and maintaining weight-bearing restrictions after injury or surgery. However, standard axillary crutches (SACs) can lead to overuse and other injuries and restrict upper limb movement. Hands-free crutches (HFC) do not restrict upper limb movement but their effect on balance control, with or without commonly prescribed walking boots, is poorly understood. The purpose of this study was to compare the effect of crutch type (SACs vs. HFC) and boot use on whole-body angular momentum (RAM), a measure of balance control. Participant's balance confidence, pain, comfort, and device preference were assessed. Seventeen participants were evaluated while walking without a crutch (NONE), with SACs, and with an HFC, and walked with and without a walking boot in each crutch condition. The gait pattern used with SACs resulted in significantly greater limb angular velocity (p < .05), and an 84% increase in RAM (p < .001) as compared to the HFC. There were no differences between the SAC and HFC for balance confidence, pain, or comfort, however most (71.1%) participants preferred the HFCs. These results suggest that individuals can better control angular momentum with the HFCs and thus may be less susceptible to loss of balance.

Assistive devices are designed to enhance individuals with disabilities' functional abilities. The rise of 3D printing technology enabled the production of individualized assistive devices (IADs). A REHAB-LAB is intended for IAD provision involving technical referents and occupational therapists. This study aimed to develop the REHAB-LAB logic model; to explore its fidelity and desirability; and to explore the characteristics of arising initiatives of IAD production. The REHAB-LAB logic model development involved stakeholders throughout the research process. A pragmatic multimethod approach followed two phases 1) logic model development and 2) exploration of its fidelity and desirability. The REHAB-LAB logic model presented the resources (equipment, space, human) required to implement IAD provision in a rehabilitation center, and the expected deliverables (activities and outputs). The REHAB-LAB logic model highlights the interdisciplinarity of IAD provision including occupational therapists, doctors, engineers, managers, and technical referents and places the users at the center of the IAD production. Results confirmed the fidelity and desirability of the REHAB-LAB logic model. The REHAB-LAB logic model can be used as a reference for future healthcare organizations wishing to implement an IAD provision. This research highlighted the interest of IAD provision based on the REHAB-LAB model involving users and transdisciplinary practices.

In this study, we aimed to investigate the benefits of co-design prompts/aids in the development of assistive devices for and with older adults who have cognitive impairment (CI), with the goal of improving their ability to live independently at home. We conducted a series of co-design workshops and utilized eight sets of multi-sensory aids to explore their values and effectiveness in engaging older adults with CI in co-design processes. Our findings revealed that the co-design aids had several benefits, including: (1) increasing the exchange of knowledge and awareness between older adults and designers; (2) eliciting insightful information through multi-sensorial aids, and (3) generating novel assistive design solutions to support seniors' independent living at home. We discuss our findings in relation to the multi-sensorial attributes of co-design aids, which empower older adults with CI to express their opinions and actively participate in co-designing assistive devices that meet their needs/expectations.

Worldwide, there is an increasing demand for assistive technologies (ATs) that can support people to live independently for longer. Health-care professionals (HCPs) often recommend AT devices, however there exists a lack of availability of devices and appropriate training in the field. This systematic review aimed to synthesize the available evidence into the experiences and training needs of HCPs in relation to AT. Six electronic databases were searched without date restrictions: MEDLINE, PsycINFO, SPP, SSCI, CINAHL, and ASSIA. Journal handsearching, searching reference lists of included studies and relevant reviews, and contacting experts in the field of AT were also conducted. Findings were analyzed using narrative synthesis. Data from 7846 participants from 62 studies were synthesized, eliciting perceived challenges in access to and provision of training, resulting in knowledge gaps across disciplines and geographic locations. Mechanisms to mitigate these issues included ongoing support following training and tailoring education to meet individual needs since comprehensive training is essential to maintain and improve competence, knowledge, and confidence. Further research is required to explore the impact and effectiveness of AT training for HCPs to ensure that users of devices are supported to live independent and healthy lives.

Having the skills to self-manage the demands of academic life in third-level education is critical to the successful completion of courses taken there. Independent study behavior is an aspect of university life that pervades all topics but one that requires the self-management of time in relation to study goals. Individuals with additional educational needs, such as autism, often have difficulty self-managing independent study. This may result in students failing to meet the standards required for successful course completion. The current study (n = 2) used a range bound changing criterion design to evaluate the effects of a behavioral intervention that included assistive technology in the form of a smartphone and wearable smartwatch. The intervention aimed to increase the duration of independent study behavior among university students with autism. The intervention combined self-management (goal setting, self-monitoring, self-recording) together with assistive tech. to prompt engagement in, and recording of, independent study behavior. Findings showed the intervention to be effective at increasing independent study duration for autistic adults attending third-level education.
