5To support your back, try the following:● Use a chair that supports your lower back (see detail 1).● Adjust your work surface and chair height to assume a comfortable and natural body posture (see detail 2).To promote comfortable leg postures, try the following:● Clear away items from beneath your desk to allow comfortable leg positioning and movement.● Use a footrest if your feet do not rest comfortably on the floor.To minimize reaching and to promote comfortable shoulder and arm postures, try the following:● Place your keyboard and mouse or trackball at the same height; these should be at about elbow level. Your upper arms should fall relaxed at your sides (see detail 3).● When typing, center your keyboard in front of you with your mouse or trackball located close to it (see detail 4).● Place frequently used items comfortably within arm’s reach (see detail 5).To promote proper wrist and finger postures, try the following:● Keep your wrists straight while typing and while using a mouse or trackball. Avoid bending your wrists up, down, or to the sides. If your keyboard has legs, extend them if this helps you maintain a comfortable and straight wrist position.● Type with your hands and wrists floating above the keyboard, so that you can use your whole arm to reach for distant keys instead of stretching your fingers.X118135401mnl.indb 5 1/19/2006 12:12:15 PM
