Summary: This study aimed to compare how older adults and young adults control their postural stability after stepping on a stair. Older adults were found to have difficulty stabilizing their body posture after stair ascent, particularly in terms of time to stabilization in the anterior-posterior direction.

Summary: The study aimed to compare the effects of video game training and traditional motorcognitive dual-task training on dual-task interference in older adults. Both types of training showed significant reductions in dual-task cost in amplitude, velocity, and Lyapunov, indicating they are suitable treatments for improving dual-task interference.

Summary: This study investigated postural control performance and cortical activities under different visual conditions using a virtual reality system and functional near-infrared spectroscopy. The results showed that concurrent visual and postural perturbations could facilitate cortical activities in specific brain regions, while visual distractors deteriorated postural control ability and cortical activation in corresponding brain regions.

Summary: The current study found that the amount of initial practice mediates the degree of dual-task interference observed when performing a novel speech production task with an attention-demanding visuomotor task.

Summary: This study investigated the effects of age and attentional focus instruction on postural and supra-postural tasks among older adults with mild cognitive impairments. The results showed that external attentional focus instruction had a positive impact on postural control, and supra-postural tasks were more beneficial for postural function compared to postural tasks. Therefore, designing training programs with supra-postural tasks can improve balance in older adults with mild cognitive impairments.

Summary: The study found that visually demanding secondary tasks have a greater impact on the performance of older pedestrians during road crossing compared to cognitively demanding tasks. Older participants showed increased errors and response time, and reported higher subjective workload during dual-task conditions.

Summary: This study compared the synergistic effect of cognitive training and aerobic/resistance physical exercise on dual-task performance in older adults, showing that the combined training protocols had a positive impact on task-set cost, while cognitive training specifically improved dual-task cost.

Summary: This study examines the dual task interference of cognitive and postural activities by setting individualized difficulty levels for tasks. The results show that postural sway features are affected by the individualized difficulty level, with more significant reductions observed in challenging postural tasks.

Summary: The study found that working memory capacity plays an important role in selective visual attention, with individuals having higher capacity performing better in the task. Additionally, visual stimuli located along the same meridian were perceived more accurately compared to stimuli located along different meridians.

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: This study examines the effects of cognitive and physical loads on dynamic and static balance performance of healthy older adults under various task conditions. The findings indicate gender differences, minimal impact of age on balance performance, and a decrease in dynamic balance performance under cognitive load. The study suggests that future research should consider the differences between dual- and multi-task methodologies in studying balance and control in older adults.

Summary: This study examines the effect of concurrent cognitive task on older adults' balance recovery stepping abilities from unannounced lateral perturbations while walking. The results show that cognitive load does not significantly affect balance recovery reactions in older adults, suggesting a posture first strategy. However, trade-offs between cognitive and postural performances were identified.

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: This study examined the effects of apathy and dual-task condition on postural control of chronic stroke survivors. The results showed that apathy exacerbated postural control impairments in these survivors, but concurrently performing a cognitive task reduced the impairments.

Summary: The study found that participants of different ages and work paces choose different movement sequences (WoDs) when performing repetitive light assembly tasks, but this does not affect their work efficiency. In practice, allowing operators to vary their movement sequences can help alleviate strain on the locomotor system.
