What is the primary role of pelvic rotation during gait?

The primary role of pelvic rotation during gait is to maintain balance and regulate speed. The pelvic rotation contributes to a smooth and coordinated movement pattern, allowing for efficient transfer of weight from one leg to the other during walking. This rotational movement helps to stabilize the pelvis and trunk, which in turn supports overall body balance as the center of gravity shifts with each step.

Additionally, the rotational mechanics of the pelvis can help to manage the walking pace, allowing for adjustments in speed as needed. Efficient pelvic rotation minimizes excessive lateral sway and promotes a more fluid gait, reducing the risk of falls and ensuring stability during ambulation.

In contrast, while enhancing foot clearance, increasing stride length, and facilitating knee flexion are important aspects of gait biomechanics, these actions are secondary functions supported by the primary role of pelvic rotation in maintaining balance and regulating gait dynamics.
