Chiropractic’s Basic Theory Vertebral Subluxations are displacements of the spinal bones (vertebrae) that can cause endangering stress to your spinal cord and nervous system. These subluxations are often due to poor sleeping habits, poor posture, strenuous exercise, injuries, auto accidents, sports, slips or falls, and the birthing process itself. Chiropractic adjustments are very helpful in correcting these subluxations and restoring optimal health. Subluxation Normal nerve Pinched nerve Normal nerve
