Fig. 7From: The influence of walking speed and effects of signal processing methods on the level of human gait regularity during treadmill walkingEffect of changing vector length (m) on the vGRF SampEn for different processing methods (r = .02). (WHOLE) raw time series; (SEGM) segmented and resampled signal; (NORM) segmented, resampled and normalized signal; (ZERO) segmented, resampled and detrended signal; results for walking with preferred (Vpref) and maximum tolerated (Vmax) speed; the error bars indicate 0.95 confidence intervalBack to article page
