The Sensory Integration Education & Research Foundation (SIERF) believes there is an acute need to develop an understanding of Sensory Processing Disorders in Los Angeles and around the world, where still so many are so unaware to have the ability to address those diagnosed with sensory processing disorders which impact child development and adult success. The current terminology sensory processing disorder (SPD) is defined as difficulty turning sensory messages into controlled behaviors that match the nature and intensity of the sensory information. The behaviors, resulting from difficulty responding to sensory information, disrupt learning, social competence and mastery of daily living skills needed for a child to succeed with developing appropriate skills needed for success at home, in school, in the community and later in the work environment. Currently more and more parents and professionals have become aware of the tremendous impact of this disorder on success with life skills and are seeking services from trained professionals. Thus the need for training and treatment is rapidly increasing. Research data has reported that the percentage of persons with this disorder is wide ranging – from 15% in the general population to upwards of 95 % in persons diagnosed within the autism spectrum.

The Senses - Vestibular – inner ear - Proprioception – tendons, joints, ligaments, muscles - Tactile – skin - Auditory – ear - Visual – eyes - Taste - Smell Vestibular System - Increased sensitivity to movement may lead to fearful reactions to swings, slides, ramps, or inclines, feet leaving the ground, head upside down, etc. - Trouble learning to climb or go down stairs or hills.

The Senses Our senses give us information about the world, about the physical condition of our body and the environment around us. Efficient processing of sensory information allows us to organize/integrate this information so that we can respond in an adaptive manner within our environments. Input from the senses is coordinated at the brainstem level and includes regulation of the emotions.

Years -The episode of extreme tantruming is way out of context. The child is unable to recover (modulate) without help from an adult as compared to a regular 2 year old tantrum. - Difficulty with transitioning. - Staying calm in places where there is smells that are offensive to the child, noise or visual stimulation e.g. grocery stores, malls, etc. - Motor delays in sitting up, standing, climbing or showing appropriate caution. - Mastering toileting. - Mastering expected hand function tasks involving silverware use, manipulating toys, etc. - Imitating simple movements.

Sensory Modulation/Regulation Continued - Sensory modulation is a neurological function that is responsible for producing this composite picture. - Sensory modulation occurs automatically, unconsciously & without effort in typically developing children. - For children with developmental challenges, the process may be inefficient, demanding effort & attention with no guarantee of accuracy. - Sensory modulation provides crucial foundation for later, more complex learning & behavior.
