How aging impacts cortical dynamics and gait during dual-task turning revealed by fNIRS.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The aim of this study is to explore the differences in cortical activation and gait performance during turning walking under cognitive dual-task conditions between young and older adults during cognitive-turning dual task walking, as well as variations in brain functional connectivity in this context. Seventeen young adults and seventeen older adults were included in the study. All participants completed two tasks: a figure-eight turning walk (single-task, ST) and a figure-eight turning walking while performing a digital alert cognitive task (dual-task, DT). Data collection was conducted using functional near-infrared spectroscopy and a three-dimensional motion capture system to extract and calculate the activation of motor and sensory cortices, functional connectivity, and gait parameters. Compared to ST, the cortical activation in the young adults was significantly increased during DT (p ≤ 0.041) and was higher than that of the older adults (p ≤ 0.003); the older adults showed no significant change in cortical activation, and the stride length decreased (p = 0.013) and was lower than that of the young adults (p = 0.023). Additionally, compared to ST, the functional connectivity between primary somatosensory cortex and other brain regions increased in the older adults during DT (p ≤ 0.035). The older adults are more likely to fall when performing cognitive-turning DT. One of the important reasons for the difference between them and young adults is the distinct brain modulation mechanisms employed by the two groups when facing challenging dual tasks. Enhancing brain functional connectivity may be a more effective strategy for the older adults to promoting dual-task performance. This study provides insights for aging-related steering disorders and more evidence for the influence of aging on neuro-motor control mechanism.
