Lower crossed syndrome - posture. Which description best fits the typical posture?

• A. Anterior pelvic tilt with increased lumbar lordosis.
• B. Posterior pelvic tilt with decreased lumbar lordosis.
• C. Neutral pelvis with flat back.
• D. Pelvic tilt with knee flexion.

Answer: (A)

Lower crossed syndrome is driven by a pattern of muscle imbalance where the hip flexors and lower back muscles are tight while the abdominals and glutes are weak. This pulls the pelvis forward (anterior pelvic tilt) and increases the curve of the lower spine (lumbar lordosis). That combination describes the posture in which the pelvis tilts forward and the lumbar spine becomes more lordotic. Why this fits best: an anterior pelvic tilt with increased lumbar lordosis directly reflects the typical imbalance—tight hip flexors and back extensors pulling the pelvis forward and lifting the front of the pelvis, while weakness in the abdominal and gluteal muscles fails to counteract that pull. Why the other descriptions don’t fit as well: a posterior pelvic tilt with decreased lumbar lordosis would flatten the lower spine and tilt the pelvis backward, opposite to the typical pattern. Neutral pelvis with a flat back lacks the pronounced anterior tilt and lumbar curvature. A vague pelvic tilt with knee flexion doesn’t capture the characteristic forward-tilting pelvis and increased lumbar curve specific to lower crossed syndrome.
