Can the humpback of adults be restored by back improvement?

It's hard for adults and it's been exposed for a long time. Just stretching hard does not guarantee that the spine is straight. If the humpback is corrected with orthopedic heel shoes, there is a test method in the patent of this invention. Barefoot, step on a book 2 cm in front of your feet, and step on the ground with your heel, so that you can correct your posture by moving your center of gravity back. You can try it first and buy it if it really works. This is a correct test to identify the function of heel shoes. Otherwise, it is the same to correct hunchback by leaning against the wall, with the center of gravity at the back, but the method of leaning against the wall can't always carry the wall, and shoes with heels can always be worn.
