When you're focused on a screen, your shoulders creep up toward your ears. Your arms reach forward. Your upper back rounds. This position compresses the muscles and joints in your shoulder complex.
Hours of this creates what physical therapists call "upper crossed syndrome" â tight chest and neck muscles, weak upper back muscles. The result is chronic shoulder pain that painkillers can't fix.
Your shoulders aren't designed to stay in one position for hours. They're meant to move through their full range of motion throughout the day. Desk work denies them this movement.
Common Causes
Mouse reaching â Extending your arm to use a mouse strains the shoulder
Keyboard position â Typing with shoulders elevated causes tension
Monitor placement â Looking up or down affects shoulder position
Stress holding â We unconsciously tense shoulders when stressed
Static posture â Not moving for hours lets muscles tighten
