除了平均步态间隔，步幅与步幅的变异性被认为传达了关于神经控制机制的重要信息。步距变异性具有长程相关性，并用标度指数来描述其类分形性。然而，其生理起源和具体机制尚不清楚。根据我们的仿真结果，我们发现相位重置可以产生长程相关时间序列数据。考虑到相位重置也与脊上神经控制系统有关，本文认为它可能是步态变异的一种原始机制。
Other than average gait interval, stride-to-stride variability is believed to convey important information about neural control mechanism. Long-range correlation is found in stride interval variability and scaling index is used to describe the fractal-like behavior. However, the physiological origin and specific mechanism are still unknown. According to our simulation finding, it is found that phase resetting could produce long-range correlation time series data. Consider that phase resetting is also related to the supraspinal neural control system, this paper proposes that it may function as an original mechanism for the gait variability.
