Summary: This study investigated the immediate effect of attentional focus on dual-task walking and the training effect of attentional focus on walking, freezing of gait (FOG), and falls in participants with Parkinson's disease. The findings suggest that external-focus enhances walking automaticity and concurrent task accuracy for non-freezers, while internal-focus increases gait stability and has a positive effect on improving locomotion control and reducing falling risk for freezers.

Summary: Participants exhibited more local instability during self-paced treadmill walking compared to fixed-speed walking, and reduced stride time variability was not observed during self-paced dual-task walking. Dual-task interference effects were greater on stride time variability, local dynamic stability, and cognitive performance during self-paced walking. The results suggest that self-paced treadmill walking poses greater challenges and can serve as a better alternative to fixed-speed walking for dual-task investigations.

Summary: Technology advancements in smart glasses provide new opportunities for on-the-go interaction with technology. This study compared the use of two types of smart glasses (Everysight Raptor and Vuzix m100) for reading during walking to using a mobile phone. Results showed that when using smart glasses, participants walked slower with larger gait variability, read less text with lower comprehension scores, and perceived the glasses as less usable and more demanding than the phone. The findings highlight the negative impact of using smart glasses during walking and suggest the need to consider human attentional capacity when designing smart glasses interfaces and future urban environments.

Summary: Heterogeneous graph embedding is a method to learn low-dimensional representations from a graph with diverse nodes and edges, while preserving the underlying topology. Existing methods rely on hand-crafted meta-paths to explore the semantics of the graph, but these methods are prone to errors when the test distribution deviates from the priors. In this paper, a self-learning scheme called self-guided walk (SILK) is proposed, which bypasses meta-paths and learns adaptive attentions for node walking. Experimental results on four real-world datasets show that SILK outperforms state-of-the-art methods.

Summary: A novel rehabilitation device AN-EXTRA-Push was proposed, utilizing a brake and an elastic tendon to assist push-off by harnessing energy during stance phase and releasing it during push-off. The feasibility of the device was studied, with key parameters of brake engagement timing and elastic tendon stiffness determining the level of exoskeleton assistance. Insights from the study highlight the importance of timing in assistive torque, particularly the assistance termination determined by brake disengagement timing.

Summary: Previous research has shown that mechanical phase variables can accurately quantify the progression through a human gait cycle, even in the presence of disturbances. This study compared kinematic parameterization methods based on time, thigh phase angle, and tibia phase angle, finding that both phase parameterization methods were superior to time parameterization, with thigh phase angle generally better than tibia phase angle.

Summary: This study aims to investigate the effects of serial BLTT on spatial aspects of backward and forward walking in chronic post-stroke individuals with residual walking impairment. The results show an overall improvement in BLTT and overground walking speeds, bilateral step lengths, and single-support center of pressure distances over six training sessions. Additionally, there were weak positive associations between changes in BLTT speed, BLTT paretic step length, and overground forward walking speed.

Summary: This article proposes a novel human-in-the-loop control framework for a fully actuated lower limb exoskeleton, allowing users to walk without external stabilization tools. The control strategy is designed to imitate the natural lower limb motion of users through barrier energy function and regional functions. The proposed strategy controls the exoskeleton to follow appropriate ergonomic trajectories using an adaptive controller considering human effort and robot capabilities.

Summary: This study investigated the influence of different cognitive loads on the neural control of muscle activity during dual-task walking. The results showed that stride-time variability decreased and reaction time increased during walking with a digit 2-back task compared to normal walking and walking with watching digits. The intramuscular coherence in the beta band significantly increased during walking with the digit 2-back task. These findings suggest that young adults can enhance their central neural drive and reduce walking variability for cognitive tasks during dual-task walking.

Summary: This study compares the cueing effect of chromatic and achromatic colours in mitigating viewport switching cost in multiple-view visualisations, finding that chromatic colours contribute to better within-viewport attention management. By reducing the depletion of working memory resources on overcoming viewport switching cost, valid chromatic cues play a positive role in attention management in multiple-view visualisations.

Summary: To navigate complex environments, people must decide how to direct gaze to acquire relevant information and decide where, when, and how to move the body. Recent work supports the idea that gaze may be directed to reduce task-relevant environmental uncertainty and to ensure movement accuracy based on the cost (or effort) to move the body and maintain balance. Gaze and step decisions may relate to the value a person assigns to information gain, being certain of their actions, and conserving energy.

Summary: Increasing cadence significantly reduces peak impact force and instantaneous vertical loading rate during running, while acoustic pacing has no significant effect on impact forces and can be used to reduce impact force without introducing a counterproductive effect. Step-based and stride-based pacing also show no significant differences in impact force reduction.

Summary: The study aimed to investigate whether individuals can modulate their duty factor based on verbal instructions to change either their stance or flight time without changing their cadence, and which instruction is most effective. The results showed that participants were able to change their duty factor in the intended directions with verbal instructions. However, the instructions and acoustic pacing did not result in a consistent change in cadence. This suggests that running styles can be altered with verbal instructions to change stance or flight time for duty-factor modulation.

Summary: This study investigated the fatigue experienced by polio survivors during 6-min walking and how it influenced their normal and adaptive walking. The results showed that leg-muscle activation declined over time during adaptive walking and cardiorespiratory fatigue increased during all tests, especially in polio survivors. Furthermore, walking adaptability was further degraded by cardiorespiratory fatigue during narrow-beam walking in polio survivors. These findings suggest that fatigue might increase the risk of falls among polio survivors.

Summary: This study examined the differences in postural adjustments between erect, hyperlordotic, and swayback postures when facing external perturbations. The findings suggest that adopting hyperlordotic and swayback postures alters the contributions of the active and passive subsystems of the spine in postural control, potentially reducing the spine's ability to withstand loading and shear forces.

Summary: This study investigated sex differences in lower limb dynamic joint stiffness (DJS) during walking in older adults. The results showed that ankle DJS was lower in older women, which was caused by the reduced ankle plantarflexion moment. However, knee DJS did not elucidate the cause of knee osteoarthritis (OA) in older women.

Summary: This study investigates the effects of footwear type, navicular drop and ankle pronation on lower limb joint stiffness during running. The results show that navicular drop and dynamic ankle pronation do not affect joint stiffness, but footwear type significantly affects joint stiffness. Conventional footwear increases ankle and hip joint stiffness while reducing knee joint stiffness, which may have implications for injury risk.

Summary: This systematic review is the first to compile evidence on the effect of the menstrual cycle on postural control. The evidence regarding the influence of the menstrual cycle on postural control is unclear. However, a trend of decreased postural control from the early follicular phase to the ovulatory phase was observed in balance tasks that eliminated or altered sensory input.
