Flashcards
Neutral Body Posture
Neutral Body Posture
A posture that places the least amount of stress on the body by evenly distributing physical stress. Often referred to as 'zero gravity posture'.
Carpal Tunnel
Carpal Tunnel
A channel in the wrist surrounded by bones and a nonelastic ligament, through which blood vessels, tendons, and the median nerve pass.
Carpal Tunnel Syndrome
Carpal Tunnel Syndrome
A condition caused by increased pressure in the carpal tunnel, often due to repeated movements or bent wrists, leading to tingling, numbness, pain, swelling, and burning sensations in the hand.

Study Notes
Office Ergonomics
- A neutral body posture puts the least amount of stress on the body
- With a neutral posture, physical stress is evenly distributed
- Neutral body posture is also called "zero gravity posture" and "neutral position"
Sleeping Astronauts
- Astronauts exhibit the neutral position while sleeping due to the lack of gravity
Neutral Position
- In a neutral position the back is straight
- There is a 90° bend in the hip
- There is a 90° bend in the knee
- The head and neck are straight
- The shoulders are relaxed
- There is a 90° bend in the elbow
- The wrists are straight
Carpal Tunnel
- Carpal tunnel is a channel in the wrist surrounded by bones and a nonelastic ligament
- Several blood vessels, nine tendons, and the median nerve pass through this channel from the forearm into the hand
- Certain movements, especially repeated movements and bent wrists, can increase pressure in the carpal tunnel
- Symptoms of increased pressure in the carpal tunnel include tingling, numbness, pain, swelling, and burning sensation in the hand
Chair Positioning
- The back should be straight when sitting in a chair
- Your chair should fully support the S-curve in your spine
- The hips and knees should be at a 90° angle
- The feet and arms should be supported
Good Chair Characteristics
- The seat pan should be tilted backwards
- The backrest should be tilted
- The backrest should have a lumbar pad
- The backrest angle should be adjustable, with a locking mechanism
- The seat pan should have a waterfall edge design
- The chair should be fully adjustable, including the heigh and position of the armrests
Keyboard & Mouse Positioning
- The keyboard should be 2-3" lower than desk height
- If you can't lower the keyboard, raise your chair
- Center the alphabetical section of the keyboard to your body
- Keep the keyboard flat
- Only use a wrist rest pad when not actively typing
- Place the mouse next to your keyboard
Alternative Keyboards
- NIOSH found no difference in comfort or fatigue with alternative keyboards, and no evidence that they reduce risk
- Good work practices are key to good ergonomics at a computer workstation, not specific equipment
Monitor Positioning
- Position the monitor in front of the keyboard
- The top of the monitor should be at eye level
- The monitor should be an arm's length away
- Tilt the monitor backward by 10°
Glare
- Glare can cause eye strain and headaches
- Position the monitor between overhead lights and perpendicular to windows
- Select a glare screen for the model and size of monitor
Document Positioning
- Position documents next to the monitor at the same height
- Positioning documents to the side reduce head and neck movement
- Positioning documents to the side reduce eye refocusing distance
Telephone Use
- Cradling the telephone between neck and shoulder creates an awkward position
- Use a shoulder rest, speaker phone, headset, or Bluetooth device
