Hip Joint Range of Motion

The primary function of the hip-joint musculature is to support the weight of the head, arms, and trunk both in static erect posture and in dynamic postures. The ranges of motion for the hip joint are:

• Hip flexion — 90 degrees with the knee extended; 120 degrees (up to 135) with the knee flexed (in this flexed-knee position, tension in the hamstrings is released).
• Hip hyperextension — 10 to 30 degrees. (The Joint ROM chart lists hip hyperextension as 10–15°, with a handwritten "– 25.")
• Hip adduction — 30 degrees (limited by the tensor fascia lata and iliotibial band).
• Hip abduction — 45 degrees (limited by the 2-joint gracilis muscle).
• Hip medial rotation (inward) — 30 to 45 degrees.
• Hip lateral rotation (outward) — 45 to 60 degrees.

• Hip flexion: 90° (knee extended); 120° up to 135° (knee flexed — hamstring tension released).
• Hip hyperextension: 10–30° (chart: 10–15°, handwritten –25).
• Hip adduction: 30° (limited by tensor fascia lata & iliotibial band).
• Hip abduction: 45° (limited by 2-joint gracilis).
• Hip medial (inward) rotation: 30–45°.
• Hip lateral (outward) rotation: 45–60°.

• hip-complex — the anatomical hip structure.
• hip-flexors — produce hip flexion.
• hip-abductors — produce hip abduction (limited by gracilis).
