SOT stands for Sacro Occipital Technique (or Technic). "Sacro" means "related to, or associated with," the sacrum. The sacrum is the foundation for the spine. The sacrum is often called the tail bone though this is not exactly correct. "Occipital" means "related to or associated with the occiput. Occiput means "the back of the head". So, SOT is a method of normalizing the relationship between the foundation of the spine and the top of the spine. It is this relationship and how these two bones get along with one another, that has been proven to be so important in the normal functioning of the brain and spinal cord.
