A. Initial swing: the segment of a gait cycle in which the limb of interest lifts of the ground and begins to move forward, ends when both limbs are adjacent with each other (Figure 6.5E). B. Mid-swing: the initial segment of advancing the limb of interest forward, past the opposite limb. During this phase the tibia is vertical to the ground and the foot is parallel, preparing to make initial contact (Figure 6.5F). C. Terminal swing: the final 15% of a gait cycle in which the limb of interest begins to decelerate and prepare for initial contact, thus concluding one full gait cycle (Figure 6.5G).
