Summary: The objective of this cross-sectional study was to identify correlations among functional gait, cognitive function, and perceived dizziness in people with peripheral vestibular disorders and explore variables that could be used as prognostic factors of functional gait. The results showed that age, perceived level of disability, and vigilance were predictive factors of functional gait variability and high risk of falling. The study concluded that cognitive impairments affect functional gait in people with peripheral vestibular disorders, highlighting the importance of integrating cognitive assessment into rehabilitation programs.

Summary: This study aimed to examine the effects of dual-task walking on cognitive performance, gait performance, and gaze behavior in older adult fallers compared to non-fallers in a high-distraction real-world environment. Results showed that all participants exhibited decrements in gait and cognitive performance during dual-task walking, and changes in gaze behavior from single- to dual-task walking. Non-fallers appeared to have more freedom to divert their gaze to less relevant environmental stimuli while walking, and different measures of fall risk impacted patterns of gaze behavior differently.

Summary: Study on dual-task interference in older adults during walking and cognitive tasks revealed that there is a differential effect on gait and cognition, with higher cognitive cost for category fluency compared to letter fluency. In the case of letter fluency, maintaining cognitive performance resulted in sacrificing gait by increasing step width.

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: The study found that passive listening to multi-talker babble noise affects functional gait performance in both young and older adults, possibly due to the engagement of attention networks caused by the babble noise. Increasing age, worse functional gait performance, poorer hearing capacity, and lower performance on cognitive function tasks were found to be correlated.

Summary: This study explored the impact of cognitive and motor dual-task interference on oropharyngeal swallowing in patients with Parkinson's disease (PD). The results showed that oropharyngeal swallowing in PD patients is not only reflexive but also requires mental capacity, highlighting the importance of attentional resources in the central control of swallowing as a compensatory mechanism for PD-related dysphagia. The proposed dual-task protocol may be useful for challenging swallowing functional reserve.

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 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: The study aimed to assess the influence of chronotype on the effects of the lockdown on sleep and psychological outcomes. A total of 1671 participants in France filled out online questionnaires about their sleep and psychological symptoms. Statistical analyses showed that sleep quality decreased during the lockdown, with evening-type individuals being the most affected. Evening-type participants also experienced an increase in depressive symptoms. These findings suggest that individuals with an evening chronotype have lower resilience to the psychological and sleep-related effects of the lockdown.

Summary: This study investigated the cardiovascular responses to vestibular and visual stimuli in normal subjects. The results showed that visual stimuli can affect heart rate, but this effect is overridden by vestibular stimulation caused by real movement. Therefore, visual stimulation is able to modulate heart rate, but is overridden by vestibular stimulation.

Summary: We conducted a study on astronauts to explore the changes in duration judgment before, during, and after their stays on board the International Space Station. Results showed that astronauts had longer reaction times during spaceflight compared to preflight and control participants. Additionally, time intervals were under-produced during counting aloud tasks and under-reproduced during concurrent reading tasks. These alterations in time perception during spaceflight could be attributed to changes in vestibular inputs and difficulties in attention and working memory.

Summary: Patients with breast cancer often suffer from insomnia, which can have negative effects on their quality of life and cancer progression. Current approaches to manage insomnia in these patients only address sleep complaints and well-being, and may be difficult to implement after chemotherapy. Vestibular stimulation, however, has shown promising results in improving sleep and rest-activity rhythm, making it a suitable option for managing insomnia symptoms in breast cancer patients.

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 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.
