Summary: This cohort investigation identifies the primary predictors of discharge walking function for nonambulatory poststroke patients undergoing high-intensity training during inpatient rehabilitation. The results indicate that steps per day, baseline Berg Balance Scale (BBS), and paretic leg strength are the primary predictors of walking outcomes.

Summary: Most rehabilitation interventions post-SCI target sublesional spinal networks, but mammalian locomotion involves more than just that. Recovery of cortical control is essential for voluntary movement and gait modulation. Neurostimulation delivered in phase coherence with ongoing locomotion immediately alleviated primary deficits in rats with incomplete SCI.

Summary: The study found that tardigrades exhibit key features of walking similar to insects and show flexibility in interleg coordination under different environmental conditions. This suggests functional similarities in walking coordination between tardigrades and arthropods, possibly due to a common locomotor control circuit or independent convergence onto an optimal control strategy.

Summary: This paper introduces a motion remapping-based locomotion technique that provides users with a realistic sensation of climbing and descending stairs in a virtual environment. Through experiments and application tests, it was found that applying visual gains to motions of climbing and descending stairs significantly enhanced the user's perceived presence and provided a positive user experience, without causing discomfort or postural instability. The proposed technique, which only requires visual cue control, is expected to be easily applied to commercial applications.

Summary: This study investigated the effects of augmented and disrupted feedback on the relationship between pelvis dynamics and foot placement in gait. The results showed that augmented feedback strengthened this relationship, while disrupted feedback did not significantly weaken it.

Summary: This paper investigates how to walk faster for two simple 2D walking models. Open-loop analysis is conducted and the concept of acceleration factor is proposed. It is found that the acceleration factor has a fixed correlation with the velocity transition trend, independent of the step length. Based on this, walking controllers are designed and closed-loop simulations are performed to achieve faster walking speeds.

Summary: This research presents a unified model for legged movement, including walking, slithering, and swimming, based on the principle of principally kinematic equations. By generating data-driven kinematic models, the study shows that legged locomotion can be explained and predicted using body shape, regardless of the number of legs, foot slipping, and turning rate.

Summary: This study used Akaike's information criterion (AIC) to determine the optimal degrees of freedom (DOF) for the lower extremities during walking and running, balancing the goodness-of-fit and generalizability of the model. The findings suggest that the 18-DOF model is the best choice for representing the lower extremities in terms of both fit and generalizability.

Summary: The study utilized internet videos to study the gait evolution of vertebrates, finding an ancestral lateral-sequence diagonal-couplet gait in quadrupedal gnathostomes. Mammals overcame this constraint with a wider range of phase values. The diagonal-sequence diagonal-couplet gait in mammals is significantly associated with arboreality.

Summary: Research on multisensory control of locomotion has shown that adults consciously adjust their walking pace when matching it with an auditory metronome. This study extends the investigation to young toddlers and adults, revealing that new walkers can also modify their gait in response to auditory input at or faster than their natural walking pace. The study also suggests that this modulation occurs automatically across ages, without explicit instructions to modify gait.

Summary: This research aims to combine multiple redirection strategies into an adaptive framework for natural locomotion in large virtual environments. The authors determine adaptation rules through machine learning and simulation-based experiments. They also introduce a static planning strategy to optimize redirection effects.
