Sensory Integration Dysfunction also called sensory processing disorder is a neurological disorder causing difficulties with processing information from the five classic senses senses (vision, auditory, touch, olfaction, and taste), the sense of movement (vestibular system), and/or the positional sense (proprioception).

Sensory information is sensed normally, but perceived abnormally. This is not the same as blindness or deafness because sensory information is sensed but tends to be analyzed by the brain in an unusual way that may cause pain or confusion.

The concept of sensory integration comes from a body of work developed by A. Jean Ayres, PhD, As an occupational therapist, Jean Ayres was interested in the way in which sensory processing and motor planning disorders interfere with daily life function and learning.

This theory has been developed and refined by the research of Dr. Ayres, as well as other occupational and physical therapists. In addition, literature from the fields of neuropsychology, neurology, physiology, child development, and psychology has contributed to theory development and intervention strategies.


Aims of Sensory Integration:

  1. Normalize overly sensitive or under reactive to touch, movement, sights, or sound
  2. Improve of concentration and physical coordination and self control
  3. Development of awareness and movement system
  4. Improve the motor skills and language science

Play as a way of supporting psychomotor development (concentration, memory, mind, manual skills, balance).
