The neuromotor control of walking relies on a network of subcortical and cortical structures. While kinematic differences between treadmill and overground walking are extensively studied, the neuromotor control processes are still relatively unknown. Hence, this study aims to investigate cortical activation during steady-state treadmill and overground walking using functional near-infrared spectroscopy, inertial measurement units and a heart rate monitor. We observed a higher concentration of oxygenated hemoglobin in prefrontal cortices, premotor cortices and supplementary motor areas during treadmill walking. Therefore, our results suggest that treadmill walking requires higher demands on cortical neuromotor control.
行走的神经运动控制依赖于一个由皮层下和皮层结构组成的网络。虽然跑步机行走和地面行走之间的运动学差异已得到广泛研究，但神经运动控制过程仍相对不为人知。因此，本研究旨在使用功能近红外光谱、惯性测量单元和心率监测器，研究在稳态跑步机行走和地面行走过程中的皮层激活情况。我们观察到，在跑步机行走过程中，前额叶皮层、运动前皮层和辅助运动区的氧合血红蛋白浓度较高。因此，我们的结果表明，跑步机行走对皮层神经运动控制的要求更高。
