As a Moncton chiropractor, I spend a lot of time chatting to parents about their children's spinal health and what they can do at home to avoid unnecessary strain. Though technology continues to develop in the school systems, it seems that heavy chunky textbooks still end up coming home with children for homework. And, your child's spine is likely suffering due to improper weight overloading and inappropriate ergonomics with the backpack itself.
So, HOW HEAVY is too heavy? What is the PROPER way to wear a backpack?
