Valid and reliable assessment tools to test wheelchair service personnel/provider knowledge are needed to support good practice. The International Society of Wheelchair Professionals' Basic Manual Wheelchair Service Provision Test (Version 1) has been widely used across contexts and settings to assess the knowledge of personnel who provide manual wheelchair services. Test Version 2 has been recently developed according to current evidence. The objectives of this study were to assess the internal consistency reliability and construct validity for the Test Version 2. A convenience sample of 156 test-takers completed an online test with 170 multiple-choice questions. Internal consistency was measured using Cronbach's alpha, which ranged from 0.58 to 0.91 across different domains. Most questions (55.9%) were classified as "easy," while 28.2% were "medium" difficulty. Regression analysis showed that test-taker characteristics, particularly years of experience, explained nearly half of the variation in test scores (R² = 0.47). The findings provide preliminary evidence supporting the test's reliability and construct validity.

Socially assistive robots (SARs) are increasingly recognized for their potential in helping older adults age in place. Effectively meeting the diverse needs of older adults requires a proper classification of SARs' functions. However, existing function categories are primarily proposed from the perspective of researchers, rarely from older adults themselves. This study addresses this gap by employing a user-centered design approach to explore how older adults classify SARs' functions. Using the open card sorting technique, we first identified 30 functions supporting the daily tasks of older adults. Subsequently, twenty-five older adults aged 60 to 86 with diverse educational backgrounds participated in an iterative function categorization. The initial sorting ranged from 2 to 10 groups but generally centered around 4 to 6. Through multidimensional scaling and hierarchical clustering, we revealed a hierarchical structure of SARs' functions. Which identified four main categories: "Home Management," "Smart Healthcare," "Entertainment and Communication," and "Monitoring and Maintenance," with their sub-categories and super-categories. These findings provide valuable insights for designing SARs that better align with older adults' needs.

Wheelchair users with poor trunk control and postural abnormalities require additional posture support devices and wheelchair modifications to sit upright. Therefore, this study was conducted to observe the function of wheelchair users in the modified wheelchair and their satisfaction with both the modified wheelchair and intermediate wheelchair service. A descriptive study was conducted, and 14 participants were recruited through consecutive sampling. Post-intervention data were collected from these wheelchair users using the Functioning Every Day with a Wheelchair (FEW) and the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST) questionnaires. The data were analyzed through frequency tables and a two-sample t-test. The scores indicated that wheelchair users functioned well in the modified wheelchairs. The range of FEW was 4.8 to 5.6, respectively, with a mean of 5.15 ± 0.227, out of a maximum possible score of 6. The QUEST device sub-score was 4.514 ± 0.2381 and the service sub-score was 4.550 out of a maximum possible score of 5 (SD = 0.3716) indicating that the users were highly satisfied with both the modified wheelchairs and intermediate service provided. Wheelchair users functioned well in the modified wheelchair and expressed a high level of satisfaction with both the modified wheelchair and intermediate wheelchair service provided.

Dynamic Seating is an intervention used as a part of a manual or power wheelchair to provide movement against resistance in response to client force. This technology can be used for various clinical applications including preventing client injury and equipment breakage; dissipating extensor forces; providing movement for sensory input, calming, and increased alertness; increasing muscle strength, trunk and head control; and other medical benefits. The purpose of this RESNA Position Paper is to provide a definition for this technology in relation to other seating and wheeled mobility technologies as well as present clinical indicators for this seating intervention including literature to substantiate these claims. Although more recent and stronger evidence is needed, existing research does support the application of dynamic seating in numerous clinical scenarios.

Despite its widespread use, the clinical effectiveness of custom-contoured wheelchair seating for individuals with neuromuscular disorders remains unclear. A scoping review was conducted using PubMed, Scopus, and Web of Knowledge databases in November 2021 and updated April 2022. A total of 17 full text articles were included. Discussion themes were grouped based on three outcomes of interest: (1) posture and musculoskeletal deformity, (2) quantitative measures of body structures and functions, and (3) qualitative perceptions, opinions, and quality of life indicators. This review highlighted the lack of literature exploring the impact of custom-contoured seating on cardiopulmonary function, pressure injury management, and upper limb function; although, there was no indication that risk is increased compared to alternative seating and it performed well in terms of perceived user satisfaction, comfort, and function. The findings also demonstrated immediate benefits to postural alignment, although, the longitudinal effect on progression of musculoskeletal deformity compared to alternative seating is more ambiguous. This review aimed to scope the evidence-base for custom-contoured seating for wheelchair users with neuromuscular disorders to synthesize information from the existing literature, inform current practice, and identify knowledge gaps for further experimental investigation.

We evaluated a socially assistive robot (SAR) named Hyodol during a six-week intervention. This study enrolled 69 older adults with cognitive decline. To screen the eligibility, we have used the following three criteria, namely Korean-Mini-Mental Status Exam score ≤ 26). Clinical Dementia Rating 0.5-2), and Diagnostics and Statistical Manual V. Participants were divided into three groups based on their cognitive function (i.e. very mild cognitive impairment (vMCI), mild cognitive impairment (MCI), and moderate cognitive impairment (MOCI). The groups were instructed to use Hyodol at home for a six-week period. Baseline and post-intervention surveys were performed after six weeks to examine the changes in perceived health, depression, and cognitive function. The vMCI group showed a reduction in the depression score after the intervention (t = -2.447, p = 0.040), in comparison to their peers in the control group. Further, the MCI group showed an improvement in the cognitive function score after the intervention (t = 2.690, p = 0.021). No significant improvement was found among MOCI participants who used the SARs. The significance of this study was to examine whether participants with different levels of cognitive functioning would diverge after a period of intervention using the Hyodol SARs. Moreover, it presented preliminary data for services and policies for home care treatment targeted to cognitive decline in older adults.

Many conditions can lead to a result in communication difficulties in both children and adults. One intervention utilized by rehabilitation professionals to overcome the problem is the use of speech-generating devices. Although the majority of users benefit from these tools, it is reported that roughly one third eventually abandon them. Existing literature suggests a variety of factors that lead to abandonment, yet the phenomenon continues. This study seeks to understand what constitutes successful device use through a qualitative study that examines the experiences of self-reported speech generating device users to identify commonalities to offer practitioners guidance in prescribing these devices. The data from this study resulted in three preliminary themes: 1) match between user and device attributes, 2) presence of communication partner support, 3) value of occupational roles and routines and their motivational benefit for device use.

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.
