Research evidence demonstrates the negative effects of Whole-Body Vibration (WBV) and correlation between exposure to WBV and detriment to health. ISO Standard 2631-1 (1997) is the accepted standard for human exposure to WBV in vehicle vibration, and provides vibration guidelines for health and comfort. These standards have not been applied to power wheelchairs (PWC), and no clinical tool exists that measures vibration levels during live power wheelchair driving. This study measures WBV and shock levels during PWC driving, considering the impact of terrains, base configurations, and seat cushions. A sensor tag accelerometer was used to measure vibration and shock in three different PWC configurations driven over seven different terrains. Data was collected for two runs per wheelchair, per terrain type, per cushion type. Differences were significant (p < .001) for overall mean and median peak vibration compared across the seven terrains, and for overall mean vibration for basic and enhanced cushions. Differences were also noted in mean and peak vibration in the three different base configurations (p = .0052). Results were compared with ISO 2631-1 guidelines. Mechanical shock on certain terrains created peak vibration levels with likely health risk. Results from this study can inform PWC prescription process.

The study aims to evaluate the effects of virtual reality (VR) programs on disease activity, central sensitization, kinesiophobia, body awareness, and pain catastrophizing in patients with fibromyalgia syndrome (FMS). Twenty-nine with FMS were randomized into the VR group or the control group (CG). FMS patients in the VR group were included in the VR-based relaxing treatment for 4 weeks, with one session per week. The progressive muscle relaxation technique and the breath-counting exercise were taught to participants in the CG. The Fibromyalgia Impact Questionnaire (FIQ), Central Sensitization Inventory Short-Form (CSI-SF), TAMPA, Pain Catastrophizing Scale (PCS), and Body Awareness Questionnaire (BAQ) were evaluated. Additionally, in the VR group, the Galvanic Skin Response (GSR), Simulator Sickness Questionnaire (SSQ), pain, stress, and exhaustion were assessed during each session. Post-treatment, the VR group showed significantly greater improvements than the CG in FIQ, CSI-SF, PCS, and BAQ (p < 0.05). Effect sizes in the VR group, except for TAMPA, ranged from large to very large (Cohen's d = 0.993-1.350). Although GSR scores decreased post-treatment, this reduction was not statistically significant (p > 0.05). Additionally, symptoms of SSQ, pain, stress, and exhaustion were notably reduced in the VR group. we recommend the widespread use of this innovative treatment approach in FMS patients.

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.

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.
