Sensory processing (sometimes called “sensory integration” or SI) is a term that refers to the way the nervous system receives messages from the senses and turns them into appropriate motor and behavioral responses. Our senses give us information about the physical condition of our body and the environment around us. SI involves the brain’s ability to receive, organize, and make sense of different kinds of sensations entering the brain all at the same time. When sensations flow in a well-organized or integrated manner, the brain can use those sensations to form perceptions, behaviors, and learning. When the flow of sensation is disorganized, it can result in sensory processing disorder (SPD). SI-based therapy helps patients’ neurological systems to process, interpret, and organize the stream of sensations, and therefore improves children’s behavioral and motor responses.
