From: Dynamic stability and spatiotemporal parameters during turning in healthy young adults
Walking direction for healthy young adults during straight walking, step turn and spin turn. Curves and shadows represent mean and 95% bootstrap CBs. The positive values indicate left turns while negative values right turns. Horizontal colorbars display areas where significant differences (p < 0.05) exist (A: step vs straight; B: spin vs straight; C: absolute value of walking direction in step vs spin). Meanwhile, intensity of colorbar indicates difference size from small (blue) to large (red). Color vertical lines show key events: heel strike (HS), toe off (TO), mid stance (MS). Results of time normalization are: HS1—0, MS1—22%, HS2—51%, TO1—61%, MS2—66%, HS3—100%, TO2—111%, MS3—122%, HS4—151%, TO3—162%
