I. The development of standing position Normal children are able to stand independently at 11 to 12 months and can walk with support. Prior to this, four crawls can generally be completed, and standing upright and balance responses have emerged. Most children are unstable or cannot stand, mainly due to the inability of the lower limbs to bear weight, or due to abnormal postures such as pointed feet, internal and external knee rolls, and knee hyperextension. Static balance is a prerequisite for standing alone, and dynamic balance is a prerequisite for walking alone. Second, the method of training standing position 1, support standing position pelvic control training: parents behind the child, with both hands holding both sides of the child’s pelvis, try to make it stand straight; then you can slowly rotate the pelvis training, in the training process, as far as possible to keep the child’s heel does not leave the ground. 2, single-leg stand training: parents behind the child, with both hands holding both sides of the child’s pelvis, or let the child hold the ladder frame and other objects, and then make the child’s lower limbs on one side off the ground on the mat or other objects (about 10cm high), the other side of the lower limbs to support the whole body weight, maintain 3-5 minutes; change the other side to do the same. 3, lunge standing training: parents behind the child, you can help the child to shift the weight to one side of the lower limb weight-bearing, hold 3 ~ 5 minutes; change the other side to do the same.
