Sensory Integration theory was developed by an occupational therapist, Dr. A. Jean Ayres. It is a neurological process that our sensations are perceived, interpreted and organized for effective integration with the environment. Visual, auditory, tactile, vestibular, proprioceptive, olfactory and gestation sensations are integrated at the brain stem to generate adaptive responses for functional activities. The result of sensory integration would be presented in a form of daily functional performance such as attention, emotional control, coordination, motor planning, organization and self-esteem. Adaptive behavioural responses are important for children daily self-care and study and social participation.
