During the initial swing acceleration phase, what is the knee position?

• A. 30 degrees of flexion
• B. 45 degrees of flexion
• C. 60 degrees of flexion
• D. 75 degrees of flexion

Answer: (C)

During the initial swing acceleration phase of gait, the knee is positioned at approximately 60 degrees of flexion. This position is crucial because it allows for optimal leg clearance as the foot moves forward, preventing stumbling or dragging on the ground. The 60 degrees of flexion strikes a balance between maintaining stability and providing the necessary motion for efficient progression during walking or running. In this phase, the hip is flexing while the knee begins to flex, which facilitates forward momentum. Additionally, this flexion angle is important for preparing the leg for subsequent phases of the gait cycle, such as mid-swing and terminal swing, allowing for a smooth transition and maintaining an appropriate cadence and rhythm. Thus, the 60 degrees of flexion is an essential component of effective locomotion during the initial swing phase.
