What defines the swing phase of the gait cycle?

The swing phase of the gait cycle is defined by the leg moving forward in the air. This phase occurs after the foot has lifted off the ground and extends until it prepares to make contact with the ground again. During this period, the limb is actively propelled forward, allowing the body to advance and progress down the walking path.

Understanding the swing phase is essential for analyzing gait patterns, as it encompasses critical functions like limb clearance from the ground and preparing for a smooth heel strike. The swing phase can also be subdivided into initial swing, mid-swing, and terminal swing, each serving specific movement requirements to facilitate efficient locomotion.
