What is the normal range of hip extension?

• A. 0-25°
• B. 0-15°
• C. 0-5°
• D. 0-20°

Answer: (B)

Hip extension is the backward movement of the thigh from a neutral hip position. In healthy adults, the normal closed-chain ROM for hip extension is about 0 to 15 degrees when the knee is extended and the pelvis is stabilized. This range reflects typical joint flexibility without compensation from the spine or pelvis. Values beyond roughly 15 degrees can occur with greater flexibility or different measurement methods, but 0–15 degrees is the standard normative range. The options suggesting larger ranges (0–25 or 0–20) would exceed the typical end range for most individuals, while 0–5 degrees is generally too small to be considered normal in a healthy adult.
