Children and adults with developmental disabilities may have a dysfunctional sensory system or SPD (Sensory Processing Disorder). In other words, their sensory system is not able to receive proper signals from their surroundings. Their system could be either under or over reactive to the inputs that they receive from their surroundings.
Sensory integration helps in better functioning of an individual’s sensory system. It helps the sensory system to receive the right stimulation from its environment.
