WHAT MAKES NUCCA SPECIAL? NUCCA recognizes the critical relationship between the upper cervical spine (neck) and the central nervous system and brain stem function. When the top vertebrae of the spine (called the Atlas) is misaligned, it can result in stress, tension and pressure on the entire nervous system. This can impact all functions of the body, from breathing, to digestion, to circulation. When left untreated, it can result in varying health conditions and chronic pain.
