Which shoulder girdle posture is often observed with upper limb hypertonicity?

• A. Scapular protraction and shoulder depression
• B. Scapular winging and shoulder protraction
• C. Scapular depression and shoulder adduction
• D. Scapular retraction and shoulder elevation

Answer: (D)

When the arm’s muscles have increased tone, the shoulder girdle often gets pulled into a raised, pulled-back position. The upper trapezius and levator scapulae lift the shoulder, while the rhomboids and trapezius pull the scapula toward the spine. This combination creates scapular elevation with retraction, a pattern commonly seen with upper limb hypertonicity because the muscles that elevate and retract stay tight while others don’t counterbalance them as effectively. So, the posture described—scapular retraction with the shoulder elevated—fits this imbalance in muscle tone best. Patterns like protraction with depression, winging, or simple depression with adduction point to different issues (such as weakness or nerve involvement) and don’t match the typical hypertonic pattern.
