Sensory integration refers to the process that people obtain external information through the senses of sight, hearing, smell, taste and touch, and then sort out this information through the brain, and then make corresponding behaviors through the body. Sensory training is the training of this process.

Sensory disorder refers to the unsynchronized or uncoordinated response in this process, which is mainly manifested in: clothes are always in a mess, shoes are often worn incorrectly, pain response is slow, people are afraid of heights, they are easy to bump into desks and chairs, and they often wrestle. Children's sensory education is to improve these abilities, which can improve children's concentration, social skills, emotional control and self-confidence.
