Which term refers to the first phase of the stance phase according to the Rancho classifications?

The term that refers to the first phase of the stance phase according to the Rancho Los Amigos classifications is "Initial contact." This phase marks the moment the foot strikes the ground and begins the process of weight acceptance. It is a critical phase where the body prepares to absorb shock and stabilize the limb, as this is when the initial contact with the surface occurs.

During this phase, the foot is typically positioned in such a way that the heel makes contact first, initiating the gait cycle. This step sets the foundation for the subsequent phases of walking, ensuring proper weight distribution and alignment for effective locomotion. Understanding this phase is essential for physical therapists and assistants when assessing gait mechanics and developing appropriate rehabilitation strategies for patients with walking impairments.
