One of the many adjusting techniques utilized in our office is called Diversified. This very safe adjustment technique performed by the skilled Chiropractor is very specific with accurate motion and contact point to the specific vertebrae that is being adjusted because of a subluxation. Often a "popping" or "clicking" sound is heard with this technique. That painless sound is simply the gas that is shifting and being released in the joint like when you open up a carbonated beverage.
