Using Ergonomics To Prevent Injury

1. When children use a computer:

Make sure the seat is high enough so your child can see the monitor without looking up and so your child's shoulders are relaxed when he or she types.

Use a footstool to support your child's feet if they don't rest comfortably on the floor.

Use a firm pillow behind your child's back to scoot him or her toward the front of the chair.

Adjust the keyboard/mouse and Avoid glare on the monitor screen.

2. Ergonomics may prevent musculoskeletal injuries by:

Decreasing work load

Reducing physical and mental stress caused by the workstation setup

Increasing compensation

Sharing ideas

Ergonomics can help prevent musculoskeletal injuries by reducing the physical and mental stress caused by the workstation setup. This means that by ensuring that the workstation is designed to fit the individual's needs, such as having an adjustable chair and desk height, proper keyboard and mouse placement, and adequate lighting, it can help reduce the strain on the body and mind. This can lead to improved comfort, productivity, and overall well-being, ultimately reducing the risk of musculoskeletal injuries.

3. Taking regular breaks from your work and doing stretching exercises may reduce the risk of repetitive motion injuries.

True

False

Regular breaks from work and stretching exercises can help reduce the risk of repetitive motion injuries. Repetitive motion injuries occur when the same movements are repeated frequently, leading to strain and damage to muscles, tendons, and joints. Taking breaks allows the body to rest and recover, preventing excessive strain. Stretching exercises help improve flexibility, increase blood flow to the muscles, and reduce muscle tension, which can further decrease the risk of injuries. Therefore, it is true that taking regular breaks and doing stretching exercises can help reduce the risk of repetitive motion injuries.
