Complexity of human walking: the attractor complexity index is sensitive to gait synchronization with visual and auditory cues

The dataset contains raw signals recorded by a treadmill equipped with an embedded force platform (C-mill, Motek). The signals are the trajectories of the centers of pressure of 36 individuals walking at preferred walking speed. Signals are sampled at a frequency of 100Hz. Each file contains two columns corresponding the anteroposterior and the mediolateral directions.<br>Coding for files is:<br>subj_XX_YY.csv<br>XX: Subject's ID<br>YY: Experimental condition:<br>NC: No cueing. Normal treadmill walkingAC: Auditory cueing. Treadmill walking in time with an isochronous metronome set to the preferred step frequency.VC: Visual cueing. Treadmill walking while aligning footsteps with forms projected onto the treadmill belt ("stepping stones"). The distance between the forms corresponds to the preferred step length.<br><br> Please cite the following studies that provide further details <br> [1] P.
