Sensory Integration has strong theoretical and applied technical support Sensory Integration (SI) is a concept introduced by Dr. Ayres of the University of California in 1927, who divided the senses into seven categories: visual, auditory, olfactory, gustatory, tactile, vestibular, and proprioceptive. The theory of sensory integration was introduced to China in the 1980s and has evolved over the decades, becoming more and more skillful. According to Dr. Ayres, sensory integration is the neuropsychological process by which the brain selects, interprets, connects and unifies sensory information input from different sensory pathways, such as visual, auditory, olfactory, taste, touch, vestibular and proprioceptive, and is the basis for the individual’s daily life, learning and work. Sensory integration theory is based on modern neuroscience, especially brain science. Sensory integration training is based on neurophysiological and psychological research results, exploring the exchange and integration of information between sensory organs, nerve centers and motor organs, and the influence of sensory integration ability on the overall development of children’s basic abilities. The impact of sensory integration on the future survival and development of children 1) affects their daily life and quality of life; 2) affects their learning activities; 3) affects their psychological state; 4) affects interpersonal communication between individuals; 5) affects the normal life of others. To understand the importance of sensory integration disorder, we need to understand the manifestations of sensory integration disorder, there are five main aspects 1, visual abnormalities: poor hand-eye coordination, often misread words, numbers and radicals. 2, vestibular function and movement abnormalities: not dizzy or afraid to turn in circles, poor body balance, easy to fall, clumsy movements, etc. 3. Abnormal skin sensation such as touch: over-sensitive or over-retarded, unable to tolerate exogenous contact with the body’s skin such as shampooing and bathing. Abnormalities in the senses of smell, taste and pain may also exist. 4, timid, afraid: hate shaking, afraid to climb high, slow to adapt to unfamiliar environment, etc. 5.Other: poor concentration and persistence, low efficiency, etc. The causes of sensory integration disorder can be summarized into several aspects: genetic factors, environmental factors and genetic and environmental interaction factors. Sensory integration disorder in children is mostly the result of the interaction between genetic and environmental factors, and it varies greatly among individuals. Parental anxiety Some of the parents I see tend to be anxious, and their questions are usually along the lines of “Our child cries when he or she arrives in a new environment,” “Our child doesn’t play with other children, he or she just plays by himself or herself,” or “I was left behind by the kindergarten teacher again, I was left by the kindergarten teacher again, saying that our child hit others”, “Our child is afraid to slide, swing or walk on the balance beam ……”, “Our child is always running around, “Our child is always running around and can’t stay still for a while”, “Our child often throws tantrums”, “Our child has trouble concentrating”” Our child’s motor ability is not always up”, and so on, such problems and doubts have been plagued by teachers and parents, can not be effective solutions, it is time to consider whether the child is a sensory integration disorder. If parents can discover and understand the importance of sensory integration earlier, and provide their children with appropriate family education and professional sensory integration training in time, parents and teachers will be less stressed and burdened during the growth and development of children, and children will grow up healthier and happier.
