1 How to Sit at a Computer I2 Regular computer users perform 50,000 to 200,000 keystrokes each 3day. Under certain circumstances and for vulnerable individuals, 4frequent computer use that involves awkward postures, repetition,and 5 forceful exertions may be related to nerve, muscle, tendon, and 6ligament damage.
7 If you use a computer extensively (several hours each day), many 8experts recommend that you consider properworkstation layout and 9posture techniques to minimize your risk of developing injuries of the 10hand/arm, shoulder, neck, and back.
11 Overuse injuries develop over time, and may set in morequickly if 12you spend long hours sitting at a computer at home, as well as at 13work.
14 Symptoms
15 Symptoms of a problem can include numbness in the fingers, sore 16wrists, lower back pain, oreyestrain (redness, dryness, soreness, 17temporary blurring of vision, and headaches).
18 You may also develop general aches and pains in the neck, 19shoulders, arms, back, thighs, and lower legs (posturalfatigue) or 20persistent pain or discomfort in muscles, tendons, and other soft 21tissue (repetitive strain injury).
