There are over 70 joints in our spinal column. Our daily activities can lead to restrictions in these joints and create areas that don't move as well. This can lead to pain, muscle spasms and faulty movement patterns. After assessing how your spine moves as a whole and how each vertebra moves individually, a gentle force can be applied to an individual joint to restore that motion and function of the joint. Your joints are lubricated with a thin layer of fluid. As your joints move, tiny bubbles begin to form inside this layer. The cracking sound you hear during an adjustment is simply from those bubbles popping.
