If a 12-year-old child excludes congenital causes and is only caused by improper posture, he needs to adjust his incorrect posture to have a correct body posture. While adjusting and exercising, you can learn from American chiropractic techniques and targeted rehabilitation exercises. Children also need to have the habit of changing their hunched posture. They should consciously raise their heads and chest when walking, reading and writing, and stand up after studying for a period of time. Move all the joints of the body, don't sleep on a pillow that is too high, and choose a mattress with a certain level of support. This can also consolidate your posture after adjustment.
