Parent Ms. Liu: I usually buy some mountaineering bags with spine protection and carrying systems. When placing a lot of heavy objects, the carrying function can effectively relieve shoulder pressure. I think it will be of great help to a child's spine during his growth stage.

Is the spine protection function really effective? Professionals related to orthopedics said: The principle of the spine-protecting schoolbag is that - the wide shoulder straps, chest straps, and waist belt form multi-point supports to disperse the pressure of the weight of the schoolbag on a single part; the ergonomic back panel fits the physiological curve of the back, reducing shaking friction when walking; and the reasonable internal compartment layout guides heavy objects close to the center of gravity of the body, reducing the actual sense of weight-bearing.

Bu Jinhui, a physician in the first ward of the Spine Surgery Department of Changsha Central Hospital: There is a rule for choosing a schoolbag: "Look at the design first, be careful about yourself, and try it with your children." Choose a bag with wide, padded shoulder straps, a chest strap and a belt. Do not choose a bag that is too heavy when empty, about 0.5 to 1 kg; the total weight of the bag filled with books should not exceed 10% to 15% of the child's weight, and the bottom of the bag should not exceed 5 to 10 cm below the child's waistline.
