There are many children who seem to be very smart, but they are very active, not easy to focus, and difficult to stick to one thing; they seem to know how to do things, but they are short-tempered, clingy, crying and rolling around; they look cute, but when they go out or meet new people, they are timid and shy, and they have difficulty adapting to new environments; they think they are smart and clever, but their movements are uncoordinated and clumsy, and they are better than their peers both in life and in learning. They are more of a worry to their parents than their peers; …… What is wrong with these children? It is likely that these children have a sensory integration disorder! Sensory integration disorder refers to the inability of external sensory stimulation signals to effectively combine in the child’s brain nervous system, and the body can not function harmoniously, and over time, the formation of various disorders eventually affect physical and mental health. “Sensory integration disorder in children means that the child’s brain loses the ability to control and combine the organs of the body, which will weaken the cognitive and adaptive abilities to varying degrees, thus delaying the socialization process. In modern urban families, more than 85% of children with sensory integration disorder are affected, and about 30% of them have severe sensory integration disorder. Sensory integration disorder occurs mostly in children aged 4 to 12 years old, usually these children have normal intellectual development, but have learning or behavioral disorders. These children can watch and listen, but they do not look carefully enough, do not listen carefully enough, and cannot concentrate well. These problems are often not easily detected by parents because they are not affected by homework and academic performance in preschool, and only after they go to school do they realize that they are not as good as children of the same age in all aspects, and only through medical consultation do they know the crux of their learning difficulties. Children with sensory integration disorder have the following manifestations: 1, vestibular imbalance: poor self-control, restlessness, inattentiveness in class or homework, love to make small movements, run around during class, love to provoke others, aggressive behavior, poor balance, and love to walk and fall. 2. proprioceptive disorders: uncoordinated movements, slow reactions, clumsy hands and feet, always fail to do fine movements such as handicrafts, coloring, paper cutting, etc.; never learn to jump rope, shoot a ball, or slide a roller; when writing homework, they are particularly slow, play while writing, and do not write neatly; poor planning, organization, and self-care skills, so they rely on parents for everything. 3, tactile defense: do not like to be touched by others, these children do not like to shave their heads and cut their nails when they are small, grumpy, capricious, eat hands and bite nails, afraid of unfamiliar environments, do not fit in, timid, withdrawn, poor interaction. 4.Visual Perceptual Impairment: They like to watch TV but cannot read fluently, often lose words and miss words, write slowly and untidily, reverse strokes, copy wrong questions, write wrong numbers, and often make mistakes in calculation. 5. Auditory perceptual disorders: poor language expression, inability to give a complete account of an event, poor vocabulary, difficulty in forming words, making sentences and composing essays, etc. It is best to provide them with sensory integration training. Sensory integration training does not directly repeat teaching, but takes the form of games, so that children are willing to participate. How to treat: First, a psychologist will measure and diagnose the child’s degree of sensory integration disorder and the level of intellectual development and learning ability, and then a trainer will develop an individual training plan, giving vestibular, muscle, joint, skin touch pressure, visual and auditory stimulation through some specially developed apparatus, and combining these stimuli with movement, thus opening many neural pathways in the brain and awakening some of the dormant brain cells. This opens up many neural pathways in the brain and awakens some of the sleeping brain cells, thus improving the symptoms of learning difficulties caused by sensory integration disorders. Sensory integration training usually takes one to three months to achieve significant results, and children’s academic performance, logical reasoning, comprehension, motor coordination, interpersonal relationships, eating and sleeping, and emotions can be satisfactorily improved, and children’s intellectual development can also be improved to varying degrees.
