Finally… the NUCCA adjustment. The correction itself is performed to the upper neck and typically feels completely under-whelming and painless. The amount of pressure applied is just enough to slightly dimple the skin in a slow and controlled way, no more than you would press into a ripe tomato. You will not feel any movement of the neck, nor will you hear any loud pops during a NUCCA upper cervical adjustment. This is because the amount of force applied is a gradual (not sudden) application of energy, intended to match and release the resistance of the joints. The entire adjusting process is typically 3-4 minutes, but can at times take up to 10 minutes.
Once the initial adjustment is made, 2 follow up X-ray films are taken to determine if the correction is complete. The post X–ray analysis is used to determine if the atlas was properly returned to its neutral position directly underneath the centre of the skull. Also, measurement of the neck and head is calculated to determine if the structures are balanced appropriately to gravity.
