The term “complex” is associated with vertebral subluxation because, as the word implies, the condition is multifaceted and has many components. This is due to the fact that a vertebral subluxation complex can be the root cause of many healthcare issues. When one or more vertebrae are out of place or fail to perform their intended motion, they can disrupt the nervous system’s function. Because the vertebral bones are designed to contain and protect this system, interference can cause pressure on the spinal cord or nerve roots as they exit the spinal column. When a vertebral subluxation complex manifests itself, a variety of symptoms can occur that affect the spine, its associated soft tissues, and even the tissues and organs controlled by the affected nerves. Some of the effects include abnormal muscle function, abnormal soft tissue function, abnormal nerve function, decreased range of motion, and pain. It can also lead to arthritis.
