Correct Sitting
Sit back in your chair between 100º & 110º, (Not 90º or
straight upright), with your thighs parallel to the floor. Place
your feet firmly and evenly on the floor and slightly in front of
you (the knee joint is at an open angle).
Following these steps benefit you by:
Reducing disc pressure and muscle tension significantly Placing
less stress on the joints of the lower extremities Distributing
body weight properly to avoid pressure points Providing the
stability required for tasks with high visual and motor control
circulation (computer work) Increasing and promoting blood
circulation and digestion Lowering the hydrostatic pressure on the
lower extremity circulation
Correct Monitor Position
Center your monitor directly in front of you to limit neck
twisting or side bending. Position the top of the monitor to be
slightly below eye level.
Following these steps benefit you by:
Reducing eye strain Reducing musculoskeletal stress Minimizing
neck discomfort
Correct Keyboard Position
Maintain your proper seated posture (continue to sit back in your
chair). Raise or lower the Keyboard Platform so that it is
positioned in your lap, just above your legs (height adjustment
lever must be in open position). Position the palm rest close to
your waist so that you upper arms are relaxed and are hanging
naturally close to your body (do not reach or lean forward). Keep
your forearm/elbow angles open while your palms are resting
comfortably on the palm rest (you should feel no tension in your
lower/upper arms). Keep your wrists in a neutral position (the
palm rest should feel soft against your palms). Form a straight
line with your fingers/hand/wrist while resting your palms on the
palm rest (while keying, allow your palms to glide across the palm
support). Rest your fingers on the keys (you will not
unintentionally activate the keys). Center yourself so that the
monitor, the height adjustment console, the home row keys and the
midline of your body are aligned (your neck or trunk should not be
twisted).
Following these steps benefit you by:
Reducing stress and minimizing fatigue in your arm, neck,
shoulder, and back muscles Allowing you to maintain your proper
seated posture, subsequently reducing disc pressure Adapting your
keyboard to you, not you to the keyboard Providing the necessary
micro breaks needed for your muscle recovery Increasing and
promoting your blood circulation and recuperative abilities
Placing your wrists in the safest position while keyboarding -
Wrist Neutral
Correct Mousing Position
Maintain a proper seated posture. Relax upper arm while it hangs
naturally and close to your body. Keep forearm/elbow at an open
angle (greater than 90º). Support your palm and your wrist in a
neutral position. Navigate your mouse by using whole arm
movements. (Don't skate the mouse with quick wrist movements.)
Following these steps benefit you by:
Reducing stress and minimizing fatigue in your arm, neck,
shoulder, and back muscles Allowing you to maintain your proper
seated posture, subsequently reducing disc pressure Adapting your
keyboard to you, not you to the keyboard Providing the necessary
micro breaks needed for your muscle recovery Increasing and
promoting your blood circulation and recuperative abilities |
