In which phase of gait does the foot strike the ground?

The contact phase of gait is the point at which the foot makes initial contact with the ground. This is a critical part of the gait cycle, as it marks the beginning of the weight-bearing process for that leg. During this phase, the foot transitions from a state of motion to a stable position against the ground, allowing the rest of the body to continue moving forward smoothly.

This phase is essential for proper shock absorption and stability, as the muscles and joints of the lower extremity engage to control the impact of the foot striking the ground. The contact phase sets the stage for subsequent phases such as the mid-stance and propulsion phases. Understanding this aspect of gait mechanics helps practitioners assess and treat various movement disorders related to walking.
