Sensory integration disorder refers to the disorder of sensory function integration in the brain, such as vestibular sensory disorder, left-right brain balance disorder, and visual-auditory disorder. It is mainly manifested by temper tantrums, poor body coordination, strong interest in specific colors, shapes and sounds, and inability to control strength and speed. Sensory Integration Disorder is determined by observation method, growth and development questionnaire, Sensory Integration Developmental Rating Scale, and Child Behavioral Questionnaire under the guidance of a professional physician, and a corresponding treatment plan is formulated. Sensory integration disorder is usually corrected by sensory training methods, such as auditory training, visual training and so on. Sensory integration disorders are common in early childhood. Parents who notice abnormal behavior in their infants are advised to take their infants to the doctor in a timely manner for standardized training under the doctor’s guidance.
