Summary: The study aimed to clarify the gravity-dependent regulation of muscle activities during walking in humans, finding that muscle activity could be explained by spatial and temporal modules under different gravity conditions. With decreased gravity, muscle modules acting on support phase linearly decreased while the module contributing to activation prior to foot contact showed nonlinear U-shaped modulation. The gravity-dependent modulation profiles also changed with variations in walking speed.

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: Metachronal propulsion, a phenomenon commonly seen in organisms with a shrimp-like body plan, is achieved through the beating of pleopods during locomotion. This study investigates the relationship between Reynolds number, stroke kinematics, and swimming mode in these organisms. The results show that different length scales and Reynolds numbers require different stroke kinematics to achieve different swimming modes. Additionally, different species exhibit unique combinations of kinematics that result in metachrony, suggesting the influence of factors other than length scale and Reynolds number. The study also highlights the importance of considering stroke kinematics, length scale, and swimming mode when achieving uniform phase lag in five-paddle systems.

Summary: This study investigates whether jerk cost (JC) can differentiate between swimming levels. The results show that elite swimmers have faster lap times and lower levels of JC compared to non-elite swimmers. Additionally, higher speed swimming is associated with more accelerations and decelerations, resulting in higher JC and lower smoothness. Overall, JC provides a simple and useful index for swimming technique.

Summary: Functional movement disorder (FMD) is a common manifestation of functional neurological disorder with diverse phenotypes. This meta-analysis examined the relationship between age at onset, phenotype, and gender in FMD. The study found that women had an earlier age of onset than men, and mixed FMD, tremor, and weakness were the most common phenotypes. The data supports the concept of both grouping FMD as a unitary disorder and splitting it into individual phenotypes.

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 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.
