Sensory Integration Therapy (SIT) is a treatment protocol, used to deal with sensory issues of a child having autism, ADHD, SPD, PDDNOS, Asperger's syndrome, etc...In this group, children are having hyper-sensitivities and hypo-sensitivities regarding the perception of senses in different areas like tactile (related to touch), visual, auditory, vestibular (related to postural control, balancing), olfactory (related to smell), proprioceptive (related to joint sensation) and gustatory (related to oral)...In SIT  different sensory stimulations (manual) are given based on Wilbarger's protocol. Along with that different therapeutic activities were planned according to the need of the child.

Speech or communication ..the ability to express one's thoughts or feelings is a sign of good perceptual ability and comprehension. Autistic or ADHD children have difficulties speaking because of perceptual deficits. As their perception gets corrected, these children start communicating by themselves. Some might have oral sensitivities, for which they need  Oro- motor therapies. Proper eye contact, imitation, tongue movement, and sitting tolerance are pre-requisite for developing speech.

 Speech in autistic and ADHD children is based on the development of understanding and comprehension...these group of children can already sing rhymes and can say alphabets and numbers...problems lies in communication and for this their perceptual functioning should get corrected first...

Special education is a structured programme, developed to improve the perceptual deficits of a child. Without proper perceptual function ,it becomes difficult for a child to perceive the information that he gets through the senses. Though they are hearing, they are looking at object, they are handling toys, still they can't react to a situation normally as they are unable to process  , understand and interpret the information. Because of this they can't give response to any commands, can't read and write like a nomal kid and can't behave properly in any situation. As they are unable to express their feelings, so they throw tantrums. Through special education the perceptual functioning gets corrected because of which the child with autism ADHD and  learning difficulties  starts reading and writing in a normal way and it also improves the comprehension ability of a child. They starts visualizing and analyzing information they get through senses ,thus starts  giving proper responses to commands.
