What is the normal range of hip flexion?

• A. 0-125°
• B. 0-90°
• C. 0-60°
• D. 0-150°

Answer: (A)

Hip flexion is the movement of lifting the thigh toward the abdomen in the sagittal plane. From a neutral starting position, the normal range extends far beyond a simple right angle, with the upper limit commonly cited as the full, functional capacity seen in healthy adults when measured with the knee straight. This means you can bring the thigh quite a bit forward, and that broader range is what the option representing the full upper limit captures. The other ranges describe much smaller arcs, or an arc that isn’t consistent with standard measurement in typical hip-flexion testing. So the choice that reflects the full, commonly accepted upper limit best represents normal hip flexion.
