A subluxation is a vertebral misalignment. When the spine is misaligned it can cause nerve interference which disrupts how efficiently your brain can communicate with your body and affect your overall health and function. Subluxations may be caused by emotional, chemical or physical stresses on the body. Chiropractic adjustments relieve the stress on the nervous system by aligning the spine. This allows for better brain to body communication and for more optimal health and function.
