Orthosis and method for scoliosis treatment

The invention discloses an orthosis for scoliosis treatment and further discloses a scoliosis orthosis method adopting the orthosis. The method comprises the steps that the relative displacement between a left half plate and a right half plate is adjusted to be matched with the height difference of the hips of the two sides of a patient; the upper limbs of the patient are lifted and supported on the hand supporting plates according to the heights of the hand supporting plates on the two sides; the height difference between the left half plate and the right half plate is adjusted again to apply force to the hip to act on the waist spine until the lateral bending of the waist is reduced, the left half plate and the right half plate drive the hand supporting plates on the two sides to move synchronously through the back support, the height of the hand supporting plates is adjusted, and force is applied to the upper limbs to act on the chest spine until the chest bending is reduced; a human body is driven to form
