Summary: This study introduces a new approach for calculating virtual time-to-contact (VTC) called directional VTC, which expands the evaluation of balance to include temporal, spatial, and control aspects. Through three case studies, preliminary results not only provided a closer look at balance control with multiple aspects, but also showed the effects of neurological diseases or challenging standing environments on balance.

Summary: This study aimed to investigate the effects of postural threat on sample entropy and traditional balance measures, as well as the role of physiological arousal, perceived anxiety, attention focus, and biological sex. The results showed that participants had increased physiological arousal, anxiety, and attention focus when threatened, and there were changes in sample entropy, anterior-posterior displacement, and balance frequency. Males and females responded similarly to threat, but males had significantly higher attention to balance and high-frequency sway. Increased sample entropy when threatened may reflect a shift to more automatic control, while directing more attention to balance may act to constrain these automatic changes.

Summary: Individuals with MS show poorer standing postural control during ML visual oscillations compared to controls, and blocking vision of the lower peripheral field can reduce overall sway in individuals with MS.

Summary: Elephants, as the largest legged animals, face challenges for stable standing but their postural oscillations are comparable to those of smaller animals like dogs and other species, suggesting that some aspects of sensorimotor postural control are not dependent on size.

Summary: The purpose of this review was to identify impaired postural control sub-components in people with COPD and summarize their characteristics. The results showed potential impairments in most of the sub-components, with heterogeneous characteristics for each sub-component. Reduced postural control may be associated with difficulties in activities of daily living (ADL).

Summary: This study investigates the effects of visual information on human anterior-posterior body sway in upright stance. Using a virtual reality system, researchers presented perturbations to induce body sway and found that the amplitude and velocity of visual input had significant impacts on body sway. Additionally, frequency analysis revealed that the gain of body sway increased with frequency, while coherence declined. The study provides valuable insights into how the central nervous system processes visual information for maintaining balance.

Summary: This study examines the contribution and sensitivity of different delay processes to balance. The results indicate that variable delay processes have the largest contribution to balance and are sensitive to historical context as well as current states.

Summary: This randomized controlled trial investigated the effects of dance therapy using telerehabilitation on trunk control and balance training in patients with stroke. The study found that dance therapy significantly improved trunk control and was comparable to conventional rehabilitation treatment. These results suggest that remote dance programs may be an effective alternative for stroke patients.

Summary: This study investigated the impact of cognitive impairment on the complexity of postural control in older adults. The results showed that the AD group had the lowest complexity in dual-tasking condition and a greater reduction in complexity compared to the other two groups. The complexity of postural control appears to be sensitive to the effects of cognitive impairment.

Summary: The proficiency of fundamental movement skill (FMS) is influenced by both maturation and diverse perceptual-motor experiences during childhood. This study investigates the potential changes to postural control in children after an educational gymnastics course. The results show that educational gymnastics enables children to make more rapid improvements to postural performance and control. Additionally, there are differences in postural control changes between males and females over a 3-month period.

Summary: The study found that individuals with Parkinson's disease exhibit similar postural responses to healthy individuals on an oscillatory support base, showing the ability to adjust various parameters of body balance based on the oscillation frequency.
