The Importance of Spinal Curves

Good posture is more than just a visual analysis of the way oneCurves of the spine are measured with precision by Dr Adam Fields stands, walks and sits.  It involves a scientific analysis of a spinal x-ray to calculate the spinal curves.  Engineers determined that the spine is more than 16 times stronger with the curves than if the curves are lost in life.  In fact, in our office your spinal curves will be analyzed, seated, flexing forward, arching backward and with the load of weights. 

Proper spinal curves with Pettbon Chiropractic, Dr Adam Fields, San Jose ChiropractorJust look at an Olympic power lifter who arches the lumbar spine upon lifting record amounts of weight.  This would be injurious with a rounded spine.



The cervical curve is the arc in the neck made up by the vertebrae. 

“Loss of the cervical curve stretches the spinal cord 5-7 cm and causes Disease.”       Alf Breig, MD  Neurosurgeon and Nobel Prize Recipient

Fetal Ultra Sound at 18 Weeks Showing a Cervical Curve

Notice the cervical curve on this feetal ultra sound at 18 weeks.


We have a cervical curve at 8 weeks in the womb.  As an adult your cervical curve should be approximately 45 degrees for optimum mechanical and neurological function.  When we lose the curve our spinal cord and it’s surrounding blood vessels are stretched.  This interrupts vital signal transmission to and from the brain.  Spinal curves are important! 



Research shows that a loss of the cervical curve can lead to the following:

  •      All measures of health status show significantly poorer scores as the head goes  further out in front of the body. 
  •      Chronic headaches
    Loss of cervical stretches the spinal cord. Restore your cervical curve with Pettibon Chiropractic

    With a proper curve your spinal cord is on the concave side of the curve. When the curve is lost the spinal cord is stretched leading to many health issues.

  •      Low back pain
  •      Degeneration of the spine
  •      Poor injury recovery
  •       Arm pain
  •       TMJ disorders
  •       A change in mental health status
  •       Acute and chronic neck pain
  •       Poor respiratory function/apnea
  •       Spinal cord atrophy
  •       Airway obstruction
  •       Increased vulnerability to injury

The thoracic curve (or the curve in the mid back) should not be flat or hunched.  When the thoracic curve is greater or less than normal it may be implicated in the following:

  •           An increase in falls
  •              An increased likelihood of suffering whiplash injury
  •              Sagging breasts
  •              Lowered lung capacity

Going Deeper and Looking to the Spinal Curves

As with the Olympic athlete example, the lumbar curve is essential for spinal strength and a loss of the curve is implicated in the following:

  • Degeneration of the lumbar discs (Note that a recuperation   of the curve with specific Pettibon exercises may rehydrate discs and increase their height)
  • Nerve compression leading to lower body pain, bowel/organ dysfunction
  •  Increased likelihood of disc herniations

 Scoliotic Curves     

Scoliosic helped with Pettibon ChiropracticFrom the front the spine should have no curves.  If there is a curve, depending on the size, this indicates scoliosis or a scoliotic curve.  There are health implications that will last a lifetime if untreated.  Please note that traditional/segmental chiropractic care has not been shown to be effective.  However, with the Pettibon System there is hope for people with scoliosis.

Realize that this is not standard chiropractic.  This is a system that integrates pattented spinal rehabilitation with chiropractic care to predictably and measureably help scoliosis.
