Reorganization of fractal gait dynamics by auditory cueing with scale-dependent control
Fractal gait dynamics diminish during metronome walking, but the underlying control framework remains unclear. We demonstrate that metronomic cueing does not abolish fractal structure of gait but reorganizes it via delayed, multistride error correction. Analysis reveals that the characteristic DFA curvature arises when stride timing errors are corrected using information from approximately six preceding strides. This supports the interpretation that delayed error correction contributes to the reorganization of gait dynamics during metronome walking.
