Web surfing and computer software have resulted in prolonged or repetitive use of pointing devices such as mice and trackballs. Upper extremity, shoulder, and back discomfort can result from improper or prolonged use of these devices. Here are some tips to prevent problems.

Keep it close

Keep your pointing device close to your keyboard to avoid long reach.

• Select a keyboard tray large enough for your keyboard and pointing device
.
• Position the pointer at the same level as your keyboard. Avoid reaching over the keyboard to use your mouse.
• Elevate the pointer with a small pad or book to reduce shoulder discomfort.
• Consider using a mouse bridge to position your mouse over your 10-key pad, if unused.
