Backpacks have become the most popular means by which students carry books and other articles to and from school. If used improperly, both computers and backpacks can cause unnecessary body strain. Children are especially at risk. This fact sheet provides basic information to parents and school staff on using ergonomic practices to prevent computer and backpack-related stresses or  \nCOMPUTERS  \nComputers are one example of human use of machines. Injuries related to computer use are common. Studies of adults in workplaces have found that inadequately placed computer workstations can result in a wide range of injuries. Students using computers at school--children's workplaces--are subject to the same injuries as adults. In a recent study, Cornell University researchers observed 95 elementary school children from 11 schools as they worked at computer in classrooms and computer labs. They found “striking mis-fits” between the children and the computer workstations. In every computer workstation, the monitor and keyboard were placed inappropriately high, forcing students to strain their necks, hands, wrists, arms, back and shoulders. This improper placement of the computer monitor and keyboard puts children at risk for developing painful cumulative trauma disorders (CTD’s) or repetitive stress injuries (RSI’s) . Eyestrain,  \nblurred vision, and headaches can result from sitting too close to the monitor and glare from the computer screen. As computer use in schools and homes increases, children’s health problems will also increase, especially as they get older. Poor work habits coupled with ill-fitting computer workstations can have harmful physical effects that can last a lifetime.  \nTIPS FOR PARENTS AND TEACHERSON ERGONOMICALLY CORRECT COMPUTER USE  \nTeaching ergonomics to children at a young age is critically important. They will develop healthier, safer lifelong work habits.  \n1  \n• Limit the amount of time children work at the computer, making sure they take periodic breaks during computing time.  \n• Make sure that the chair at the workstation fits the child correctly. The chair should provide proper lower back support,(a rolled up towel or small pillow can serve as an appropriate lower back support) . Use adjustable computer workstations that can be modified to accommodate children of different sizes.  \n• Children’s wrists should be level with their forearms while typing-not angled up or down. Their upper arms should be close to the body and relaxed and their elbows should be placed at angle greater than 90 degrees. The mouse should be at the same height as the keyboard. While they are working at the computer, the child’s head should be balanced on neck, not craning forward.  \n• Children’s knees should be positioned at approximately 90-to  \n120-degree angle. Their feet should rest on the floor, or on a footrest, box, stool or similar object.  \n• Reduce eyestrain by making sure that monitors are positioned to minimize glare on the screen, or install a glare screen that fits over the monitor. The monitor should also be positioned so that it is at or below the child’s eye level. The screen should be directly in front of the child, at least 18-30 inches away.  \n• Make sure that children drink enough water throughout the day since children’s muscles need adequate hydration to work properly an","cbCaisMexcD4g4rw","https://ap.wps.com/l/cbCaisMexcD4g4rw","pdf",276651,"English","# What Is Ergonomics?\n# Problems\n## Computers\n## Backpacks\n# Tips for Parents and Teachers\n## Ergonomically Correct Computer Use\n## Ergonomically Correct Backpack Use","[{\"question\":\"What is ergonomics and why does it matter for students?\",\"answer\":\"Ergonomics is knowledge about human abilities and limitations and how to apply them to equipment design for safe, comfortable, effective use.
