功能近红外光谱技术(FNIRS)在研究人类运动的神经控制方面有几个优点。它在参与者位置方面相对灵活，并允许在任务期间进行一些头部移动。此外，它价格便宜，重量轻，携带方便，几乎没有使用禁忌症。这为研究运动任务中的功能性大脑活动提供了一个独特的机会，这些人通常在发育中，以及那些有运动障碍的人，如脑瘫。然而，在研究运动障碍时，另一个考虑因素是实际进行的运动的质量以及额外的、非预期的运动的可能性。因此，为了正确解释fNIRS结果，需要同时监测测试过程中大脑血流变化和身体实际运动。在这里，我们展示了在运动任务中将fNIRS与肌肉和运动学监测相结合的方案。我们探索步态，一种单侧多关节运动(骑自行车)，以及两种单侧单关节运动(单独的脚踝背屈和单独的手挤压)。所提供的技术对研究典型和非典型的运动控制都是有用的，并且可以被修改以研究广泛的任务和科学问题。
There are several advantages that functional near-infrared spectroscopy (fNIRS) presents in the study of the neural control of human movement. It is relatively flexible with respect to participant positioning and allows for some head movements during tasks. Additionally, it is inexpensive, light weight, and portable, with very few contraindications to its use. This presents a unique opportunity to study functional brain activity during motor tasks in individuals who are typically developing, as well as those with movement disorders, such as cerebral palsy. An additional consideration when studying movement disorders, however, is the quality of actual movements performed and the potential for additional, unintended movements. Therefore, concurrent monitoring of both blood flow changes in the brain and actual movements of the body during testing is required for appropriate interpretation of fNIRS results. Here, we show a protocol for the combination of fNIRS with muscle and kinematic monitoring during motor tasks. We explore gait, a unilateral multi-joint movement (cycling), and two unilateral single-joint movements (isolated ankle dorsiflexion, and isolated hand squeezing). The techniques presented can be useful in studying both typical and atypical motor control, and can be modified to investigate a broad range of tasks and scientific questions.
