What is a phase of gait that involves the leg moving forward?

The phase of gait that involves the leg moving forward is known as the swing phase. During this phase, one leg is in the air, moving forward in preparation for the next step, while the other leg bears the body's weight. This motion is crucial for walking as it allows for forward progression and ensures that the foot is positioned for the next heel strike.

The swing phase has two distinct segments: the initial swing, where the leg moves forward from behind the body's center of gravity, and the terminal swing, where the leg prepares to make contact with the ground. Understanding this phase is essential for analyzing gait mechanics, improving walking patterns, and applying this knowledge in various physical rehabilitation or fitness contexts, including Pilates.

The stance phase, in contrast, is when the foot is in contact with the ground, supporting the body's weight. The contact phase is a subset of the stance phase, specifically focusing on the moment the foot makes contact with the ground. Lift-off refers to the moment when the foot begins to leave the ground, which happens at the end of the stance phase rather than during the forward motion of the leg.
