What is a probable result of working on the computer for extended periods of time?

• A. Lower back pain
• B. Upper cross syndrome
• C. Tennis elbow
• D. Carpal tunnel syndrome

Answer: (B)

Prolonged computer work tends to create a posture with the head forward and the shoulders rounded. This sustained position tightens the chest and upper back muscles while weakening the deep neck flexors and the scapular stabilizers. Over time, that muscle balance pattern is known as upper cross syndrome. It commonly presents with neck and shoulder discomfort and altered shoulder blade control, which fits the scenario of long hours at a computer best. The other options are more linked to specific joints or movements (elbow tendinopathy, carpal tunnel, or lower back strain) rather than the characteristic neck–shoulder imbalance seen with extended computer use.
