At heel strike, what is the typical degree of hip flexion?

During the heel strike phase of the gait cycle, the hip is typically positioned at about 20 to 40 degrees of flexion. This degree of hip flexion is essential for both stability and mobility as the body prepares to transfer weight onto the stance leg.

At heel strike, the body is transitioning from the swing phase of the gait, where the leg is moving forward in preparation for contact with the ground. The appropriate degree of flexion aids in shock absorption, as it allows the hip joint to absorb the initial impact of the foot contacting the ground, rather than placing excessive strain on the knee or ankle joints. Additionally, this range of hip flexion facilitates the forward momentum needed for propulsion during the subsequent phases of gait.

Understanding the normal range of hip flexion at heel strike is crucial for physical therapists when assessing gait mechanics and identifying potential abnormalities. It provides insight into lower extremity alignment, balance, and overall gait efficiency essential for rehabilitation and treatment planning.
