So frequently are behavioral and developmental disorders addressed through a variety of behavioral and chemical approaches that the significance of the biomechanical aspects of these conditions can be underestimated. This article introduces the importance of the nervous system with its biomechanical relationships to the spine and cranium, and the noninvasive approaches of chiropractic and craniosacral therapy for the benefit of sensory, motor, and neurological function in individuals with ASD, PDD, and SPD.

As a parent of a toddler with ASD, PDD, and SPD diagnoses, I sympathize with other parents’ drive to identify a cause and a solution. As a chiropractor with 14 years of experience and a fellowship in chiropractic pediatrics, and in pursuit of my certification in craniosacral therapy, I am additionally driven to identify a course of action that improves the structure and function of individuals with sensory, motor, and neurological dysfunction with these diagnoses. In individuals with these special needs, an approach that naturally improves the bodies’ structure or biomechanics is an essential component to their functional, educational, behavioral, and emotional development, as well as to their quality of life.

I have become aware of the many nuances and joys of viewing life through the eyes of a special-needs child. This experience has challenged me to further study and appreciate the significance of the body’s most important organ system, the central nervous system.

According to Sharon Rosenbloom, SLP, author of Souls, Beneath and Beyond Autism and mother of a son on the autistic spectrum, even the DMSR (the manual for diagnosis of individuals with ASD) acknowledges mainly language, social, and behavioral variations, yet it minimizes sensory involvement. Recognizing the significance of sensory involvement with individuals with ASD, PDD, and SPD diagnoses is the essence of realizing the significance of the nervous system.

The central nervous system is comprised of the brain and brain stem, the spinal cord, and the nerve attachments, which communicate with the body’s cells, tissues, muscles, and organs. Within just 18 days of conception, it is the first body system to develop. It evolves to encompass a communication network of more than 45 miles of nerves, which sends vital messages between the brain and body at rate of 325 mph. Within a 24-hour time frame, the communication of this system is responsible for more than 103,000 heart beats, 2,100 gallons of blood pumped, and more than 23,000 breaths, thus exercising about 7 million brain cells.

The nervous system’s importance to the body is highlighted by the fact that it is incased in protective bone—the brain by the skull and the spinal cord by the spinal column.

Furthermore, fluid flow, affected by the relationship between the sutures of the boney skull and the sacrum, as well as receptor input at the joints of the boney spinal column influence nervous system input. Therefore, improper biomechanics or body/boney mechanics can negatively impact the body’s nervous system reception affecting the body sense of position (proprioception); motion, balance, muscle tone, coordination, motor planning, and auditory-language processing (vestibular sense); and touch perception (tactile sense) essential for academic learning, emotional security, and social skills. Even further-reaching are the effects of poor mechanics on pain perception (nociception), as well as on many other body functions through the specialized communication of the autonomic portion of the nervous system. The 12 cranial nerves located at the brain stem are additionally significant to the body’s effective and appropriate sense of smell, sight, taste, and hearing. This central nervous system and its intimately related boney protection system are a profound link between a person’s external and internal environments, especially one with special needs. This link is critical in enabling a person to interact with his or her surroundings and with others.

Healthcare practitioners are challenged to quantify variations of this vital communication with individuals diagnosed with ASD, PDD, and SPD. In fact, conventional testing of neurology, such as an MRI, EEG, and varied genetic blood markers, may commonly appear unremarkable. However, in an effort to see the forest beyond the trees, or to identify improvements to be made in the function of the nervous system beyond a diagnosis, noninvasive analysis for nerve system stress (subluxations) performed by a doctor of chiropractic can yield productive information relevant to the care of these children. This author utilizes Infrared Thermography (IT) and/or Surface Electromyography (sEMG), as well as Digital Foot Scans as adjunct and illustrative tools for such analysis following a history, consultation, and examination.
