With kids heading back to school this week, I came across an interesting video about the risk of injury to children from improper use of backpacks. Several schools have banned the use of backpacks with wheels, so from now on more kids will have to carry their books instead. Orlando chiropractor, Dr. Dan Pavlik, gives some great advice for parents in this video about picking out the right kind of backpack. The doctor also cautions parents not to let their kids carry backpacks that are too heavy because it can lead to back pain and posture problems. Click here for the video.
