Method 1: daily observation, whether the child has the following 1, always like to carry a bag on one shoulder, one shoulder of the clothes always down 2, walking on both sides of the shoulder is not the same height, the head likes to tilt to the side 3, sitting at the table, the body forward lying down, tilted to the side 4, often hunchback with the chest 5, the two feet of the shoes are not the same wear and tear 6, walking with a limp 7, neck, shoulder, waist, leg pain, and with the aggravation of time. Method 2: The child’s upper body is bare, standing upright, with his/her back to the parents, who will check whether the shoulders are equal in height; (normal sides should be equal in height) 2, whether the left and right shoulder blades are symmetrical on both sides of the spinal column, and whether their lower corners are equal; (normal sides should be symmetrical, and the lower corners should be equal) 3, whether the lumbar concavities on both sides are symmetrical; (normal sides should be symmetrical) 4, whether the spinous processes are deviating from the midline. (Normal should be centered) Method 3: Forward Bending Test In a brightly lit place, parents face the child with a bare back, the child’s knees straight, feet together, stand straight, arms straight and palms together, slowly bend forward to about 90 °, and gradually place both hands with palms together in between the knees, so as to avoid the child’s torso and shoulders from pseudo-displacement. Parents’ eyes follow the child’s bending in parallel, from the cervical spine all the way to the lumbar region, paying attention to whether the two sides of the spine are uneven, and whether there is any unilateral rib bulge or unilateral muscle contracture. Asymmetry in any part of the back may indicate scoliosis. Method 4: Scoliometer examination During the forward bending test, the scoliometer is used to measure each segment of the child’s back (thoracic, thoracolumbar and lumbar), and the maximum angle of deviation and the site of the finding are recorded. If the most serious asymmetry of the back is more than 5°, then scoliosis is highly suspected.
