My son is supposed to participate in a class about back care at school. What kind of information do they give children in these classes?

The content of the class depends on who’s teaching and how much time is available. Most back care classes begin with a general awareness of posture while sitting, standing, and lying down. These classes often stress the importance of activity and exercise. They also demonstrate proper lifting and carrying techniques.

There may also be some discussion of backpacks. Children are encouraged to limit the weight in their packs to 10 percent of their own body weight. Back care classes may suggest ways to reduce the weight of backpacks, such as keeping books already used in desks or lockers.
