The significance of hand support Normally, children can support themselves with their hands and hold their heads at about 90° after 5~6 months of age, but it is difficult for children with motor dysfunction to do so. Children with motor dysfunction have some degree of brain damage, resulting in dysfunction in coordinating movements and continuously maintaining a certain posture, resulting in abnormal posture and inability to perform normal hand support movements, which may have certain effects on the child in the future if effective treatment measures are not taken to correct the abnormal movements and posture and restore the normal hand support movements. At the same time, because certain movements completed by the upper limbs, such as reaching for objects, grasping and pinching objects, etc., need to be based on the stability of the scapular girdle as well as the child’s body, combined with the coordination of movements between the head, scapular girdle and upper limbs, and the development and formation of these motor functions are often achieved by bearing a certain amount of weight. Therefore, for children with motor dysfunction should be corrected in a timely manner to restore their normal hand support movements and ensure their normal motor development in the future.
