Abstract：
Advances in neuroimaging technology, like functional near-infrared spectroscopy (fNIRS), support the evaluation of task-dependent brain activity during functional tasks, like balance, in healthy and clinical populations. To date, there have been no studies examining how interventions, like yoga, impact task-dependent brain activity in adults with chronic acquired brain injury (ABI). This pilot study compared eight weeks of group yoga (active) to group exercise (control) on balance and task-dependent neural activity outcomes. Twenty-three participants were randomized to yoga (n = 13) or exercise groups (n = 10). Neuroimaging and balance performance data were collected simultaneously using a force plate and mobile fNIRS device before and after interventions. Linear mixed-effects models were used to evaluate the effect of time, time x group interactions, and simple (i.e., within-group) effects. Regardless of group, all participants had significant balance improvements after the interventions. Additionally, regardless of group, there were significant changes in task-dependent neural activity, as well as distinct changes in neural activity within each group. In summary, using advances in sensor technology, we were able to demonstrate preliminary evidence of intervention-induced changes in balance and neural activity in adults with ABI. These preliminary results may provide an important foundation for future neurorehabilitation studies that leverage neuroimaging methods, like fNIRS.
摘要：
神经影像技术的进展，像功能近红外光谱（fNIRS），支持在功能性任务期间评估任务依赖性大脑活动，就像平衡，在健康和临床人群中。迄今为止,没有研究检查如何干预，比如瑜伽，影响慢性获得性脑损伤（ABI）成人任务依赖性脑活动。这项初步研究比较了八周的集体瑜伽（主动）与集体运动（对照）在平衡和任务依赖性神经活动方面的结果。23名参与者被随机分为瑜伽组（n=13）或运动组（n=10）。在干预前后，使用测力板和移动fNIRS设备同时收集神经影像学和平衡性能数据。线性混合效应模型用于评估时间的影响，时间x组交互，和简单(即，组内)效果。不管是什么群体,干预后,所有参与者的平衡均有显著改善.此外,不分群体,任务相关的神经活动发生了显著变化,以及每组神经活动的明显变化。总之,利用传感器技术的进步，我们能够证明干预导致成人ABI平衡和神经活动变化的初步证据.这些初步结果可能为利用神经影像学方法的未来神经康复研究提供重要基础。比如fNIRS.
