What is the range of motion (ROM) requirement for normal hip flexion during gait?

For normal gait, hip flexion is essential for the proper swing phase of walking, allowing for adequate clearance of the foot and smooth progression of the leg forward. The typical range of motion required for effective hip flexion during gait is approximately 0 to 30 degrees. This allows for sufficient movement to lift the leg without causing any compensatory strategies that can lead to inefficiencies or injuries.

When considering the other ranges, they either do not provide enough flexion (0-10 degrees) or exceed the necessary amount (0-60 degrees) that is specifically needed for normal gait mechanics. Full extension is also not relevant to the flexion needed during dynamic activities like walking, as it refers to the opposite of flexion and thus would not apply in this context. The 0 to 30 degrees is the most accurate representation of the necessary hip flexion to ensure a smooth and functional walking pattern.
