Summary: This study revealed that mouse locomotor learning is accompanied by specific paw kinematic progressions that change with different stages of performance. Mice refine interlimb coordination and stride length during learning, ultimately adopting a more variable locomotor strategy.

Summary: The study found that applying varied pelvis assistance force towards the paretic side during walking can improve weight shift towards the paretic side and increase muscle activity of the paretic leg.

Summary: Motor imagery (MI) is the ability to mentally engage in a task without voluntary movement. MI is important for motor development and skill acquisition in children. However, there is a lack of measures to assess MI responsiveness in children, creating a research gap.

Summary: The study investigated the impact of repeated movement patterns on implicit use-dependent learning mechanisms, finding that the Adaptive Bayesian model is more sensitive to variable practice, while the gradual disappearance of biases may be more in line with the Strategy plus Use-Dependent model.

Summary: Research has found that children with specific learning disorders may exhibit poorer motor skills which could be exacerbated by the complexity of motor activities and comorbidities.

Summary: Octopuses coordinate their arms through a nerve ring at the arms' base, in addition to brain-based sensorimotor integration and control. When one arm is mechanically stimulated, neural activity is generated in the nerve ring and in other arms, while the activity in the nerve ring decreases with distance from the stimulated arm. Various spiking patterns of neural activity occur in the axial nerve cords and the nerve ring.

Summary: This study examines how an individual's gaze behavior adapts during a target stepping task and found that participants increased their fixation distance and decreased their step error with practice. The results suggest that participants shifted their gaze fixation farther ahead and placed greater emphasis on the visual information used for feedforward motor control as their motor performance improved.

Summary: Muscle contraction determines animal movement and is limited by the characteristic dimensionless number of effective inertia, F. Physiologically similar musculoskeletal systems possess equal fractions of muscle's maximum performance. An optimal musculoskeletal anatomy with F close to unity enables maximum work and power delivery. External forces introduce parasitic losses and challenge traditional skeletal force-velocity trade-offs. F systematically varies under isogeometric transformations, providing insights into animal locomotor performance.

Summary: This narrative review aims to establish a framework for understanding age-related changes in neural control of human locomotor adaptation, focusing on reactive feedback and predictive feedforward control driven by sensory feedback during locomotion. The effects of aging on different locomotor adaptation paradigms will be discussed in light of the neural mechanisms underlying locomotion.

Summary: The study assessed the evidence and methodological quality of studies on implicit and explicit motor learning in typically developing children and children with developmental disorders. It found that implicit paradigms are as effective as explicit paradigms in both groups of children, but there is scope for improvement in methodological quality to draw stronger conclusions, including through retention testing, inclusion of a control group, manipulation checks, and assessment of relevant co-variables.

Summary: This study explores the feasibility of locomotor assistance with a telerobotics approach, where trainers provide physical assistance to locomoting patients through a robotic manipulandum. Initial results suggest that this approach is effective in modulating targeted gait features in patients with locomotor impairments.

Summary: The study found that there were no significant differences in the number or coordination of forward treadmill steps taken by newborns on a moving treadmill with different optic flow conditions. However, the Faster condition resulted in significantly fewer leg pumping movements compared to the Random control condition.

Summary: This study demonstrates that healthy adults are able to retain savings in split-belt adaptation over a three-week period, indicating the importance of including only naive split-belt walkers in such studies. These findings can be used to compare with long-term savings in patient groups to gain insights into successful gait training in rehabilitation.

Summary: Intermittent adaptation to novel walking patterns induced by external perturbation may lead to greater retention of adapted locomotion in stroke survivors compared to continuous adaptation.

Summary: The article introduces a miniature magnetic gearbox for driving wireless millimeter-scale robots. The gearbox is driven by a rotating external magnetic field, producing high torque and demonstrating high transmission efficiency. This miniature device enables various functionalities, including crawling, jumping, clamping, needle-puncturing, and syringe actions.
