Common postural malalignments and muscle imbalances include pronation distortion syndrome, lower crossed syndrome, and upper crossed syndrome. What is this collective pattern called?

• A. Lower crossed syndrome
• B. Pronation distortion syndrome
• C. Postural distortion patterns
• D. Upper crossed syndrome

Answer: (C)

These common compensations all reflect how muscle imbalances and altered joint positions tend to occur together, creating predictable patterns of posture. Pronation distortion describes how excessive foot pronation leads to internal leg rotation and knee misalignment; lower crossed shows an anterior pelvic tilt with weak abs and glutes paired with tight hip flexors and lower back muscles; upper crossed involves tight chest and neck muscles with weak upper back and deep neck flexors, producing a forward head and rounded shoulders. When you group these together as the overall pattern of altered alignment and muscle imbalance across the body, they’re called postural distortion patterns. The other terms refer to individual patterns, not the collective set.
