Sensory Processing Disorder

Patients with fetal alcohol syndrome, autism, traumatic brain injury, or other maladies may be more likely to have SPD, but all of us have our unique and, at times, disconcerting patterns of sensory processing. Motor planning arises from: proprioception - one's ability to sense the position of muscles and joints in space; tactile sense - feedback from touch allows one to know how hard to squeeze, to push, to pull, and so on; vision - visual feedback allows one to calibrate a movement to reach a specific target; and vestibular sense - this balance apparatus directs righting and equilibrium reactions thus establishing a "severe platform" from which to initiate a movement.
