Summary: With the growth of the world's population, limited healthcare resources cannot provide adequate nursing services for all people in need. The wheelchair-mounted robotic arm (WMRA) with interactive technology could help to improve users' self-care ability and relieve nursing stress. The proposed object affordance-based implicit interaction technology using a laser pointer can significantly reduce the user's limb involvement time in operating the WMRA.

Summary: This study compared the trunk biomechanics of a robotic assisted transfer device and a mechanical floor lift in transfer tasks. The results showed that the robotic assisted transfer device required smaller range of trunk flexion, lateral bend, axial rotation, distance, velocity, and acceleration compared to the floor lift. The electromyography signals were also smaller with the robotic assisted transfer device. Therefore, the robotic assisted transfer device may provide additional benefits and be an appealing alternative intervention to the mobile floor lifts.

Summary: A novel solar driven hybrid system composed of a concentrated solar collector, thermionic generator, and thermoelectric device has been proposed, with analytical investigations on power output and efficiency. The design parameters affecting system performance have been studied, with two different scenarios considered for the data of five cities in Asia. Results show that the increase in ratio of resistances does not have a significant effect on the efficiency and power of the process.

Summary: Device-free localization (DFL) systems utilize changes in the radio frequency channel to detect and localize obstacles in a target area. This paper proposes a modular DFL system called MA-RTI, which utilizes a multipath-assisted radio-tomographic imaging algorithm. The system is configured using a 3D spatial model and idle measurements, and achieves a localization accuracy of 1.0m in 50% of cases and 1.8m in 80% of cases when deployed in a real-world office environment with four sensor nodes.

Summary: This article introduces a mobile motion capture system,RobCap, which can accurately obtain three-dimensional kinematics of human motion with large displacements. RobCap tracks human motion in a local moving frame by installing an optoelectronic motion capture system (Codamotion) on a robotic arm and expresses the local kinematics of markers in a global coordinate system. The performance evaluation shows that RobCap has sufficient accuracy and precision to be used as a mobile motion capture system for large displacements.

Summary: This study investigated the benefits of 4-week, in-home wearable focal muscle vibration therapy on pain, balance, mobility, and sensation in people with diabetic peripheral neuropathy (DPN). Results showed significant improvements in average pain, pain interference with walking ability, and standard and cognitive Timed Up-and-Go scores. Balance and sensations improved but not significantly, with a trend towards correlation between changes in balance and baseline pain. Participants were highly satisfied with the therapy and compliance was 100%. Further studies with larger samples and better outcome measures are needed.

Summary: Inadequate provision of wheelchairs for children in low-resource settings can have negative impacts on their growth, development, health, and participation. This scoping review aimed to understand the current state of paediatric wheelchair provision in low-resource settings and identify factors, strategies, and gaps that can lead to more successful provision. The findings highlight the need for improvements in design, production, personnel capacity, and service delivery systems, as well as the importance of child-focussed provision and end-user involvement in research.

Summary: This study aimed to assess the impact of cognitive function on motor learning using the SIPPC robot in infants. The results showed that the movement strategies required for the SIPPC robot varied depending on the infants' cognition. The robot was well-matched to the cognitive ability of infants with CP, but lower cognitive ability was related to delayed improvement in motor skills.

Summary: Hallux strength is important for sports performance, balance and fall prevention. The current clinical standard for assessing hallux strength, MRC manual muscle testing, may not detect subtle weakness and longitudinal changes. To address this, we developed a new load cell device and testing protocol to quantify hallux extension strength. Our initial validation study demonstrates the feasibility and repeatability of this new device and protocol, supporting further validation and refinement for widespread clinical and research use.

Summary: This study explores the requirements for accessible Autonomous Vehicles (AVs) and AV services from the perspective of consumers, particularly people with disabilities (PwDs) and older adults. The results show significant divergence in transportation choices based on the underlying causes of disabilities, as well as differences in AV preferences and desired vehicle types. The study emphasizes the importance of wheelchair accessibility, user profiles, and seamless communication with AVs across all participant clusters. It also suggests a moderate comfort level with AV deployment among PwDs and older adults.
