"Ergonomics" is a body of knowledge about human abilities and limitations and how these abilities and limitations should be applied to the design of equipment, machinery, and other devices to ensure safe, comfortable and effective use. Most homes and schools today are equipped with computers for student use. 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.
