From: Dynamic stability and spatiotemporal parameters during turning in healthy young adults
MoSA and MoSP for healthy young adults during straight walking, step turn and spin turn. Curves and shadows represent mean and 95% bootstrap CBs. Horizontal colorbars display areas where significant differences (p < 0.05) exist (A: step vs straight; B: spin vs straight; C: 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%. For step turn, both MoSA and MoSP were almost consistent with straight walking in the first step. Then MoSA decreased and MoSP increased slightly in the first half of the second step. Finally, MoSA increased and MoSP decreased noticeably. Minimum MoSP appeared in initial and terminal double support phases of the third step. For spin turn, MoSA was greater and MoSP was smaller than straight walking in all three steps. Before the middle of turn phase, MoSA was greater and MoSP was smaller than step turn. Then to the middle of depart, MoSA was smaller and MoSP was greater. Finally, both MoSA and MoSP were almost consistent with step turn. Minimum MoSP occurred at MS2 in turn phase
