Which muscles are commonly tight in upper crossed syndrome?

• A. Upper trapezius, levator scapulae, pectoralis major, and pectoralis minor
• B. Lower trapezius and rhomboids
• C. Serratus anterior and latissimus dorsi
• D. Supraspinatus and infraspinatus

Answer: (A)

In upper crossed syndrome, a pattern emerges where some muscles become tight while others are weak, driven by a forward, rounded posture. The muscles that tend to be tight are the upper trapezius and levator scapulae, which pull the shoulders up toward the ears and can contribute to neck stiffness. The chest muscles, specifically the pectoralis major and minor, shorten with forward shoulder posture and pull the shoulders forward in a protracted position. This combination creates the characteristic look of elevated, forward shoulders and a forward head. That’s why this set of muscles is the best match. The lower trapezius and rhomboids are usually weak or inhibited in this pattern, not tight. Serratus anterior and latissimus dorsi don’t form the typical tight group associated with upper crossed syndrome, since serratus anterior is often underactive and latissimus dorsi isn’t a defining tight contributor in this syndrome.
