Examples of overlapped cyclograms for one healthy subject’s gait session (top) and thresholded cyclograms (bottom). Extracted (red) observations on thresholded cyclograms correspond to temporal synergies in PCA space, for the following gait speeds: (a) $2 \frac{\mathrm{m}}{\mathrm{s}}$; (b)$1.6 \frac{\mathrm{m}}{\mathrm{s}}$; (c) $1 \frac{\mathrm{m}}{\mathrm{s}}$; (d)$0.8 \frac{\mathrm{m}}{\mathrm{s}}$; (e)$0.4 \frac{\mathrm{m}}{\mathrm{s}}$. In brackets, the percentages of explained variance of the specific principal component (PC₁ or PC₂) are shown.
