I might add that we are not suggesting you would leave the cervical spine in pure neutral during this adjustment, only that you do not preload the spine in lateral flexion, rotation and then extension before you thrust. It is a little bit like introducing the movement required to the particular joint in question and then giving it a bit of kick as it flies by. The difference between adjusting the cervical spine with and without preloading is substantial. The only requirements to adjusting with less force are timing and knowledge of the anatomy that lies under your fingers. The anatomy is required for plane lines and directions of force.
Timing is a bit more complex because it requires practice and tissue sense.
Tissue sense is heightened by use of motion palpation analysis procedures and can be learned quickly. When you begin to experiment with this type of adjusting you will find many advantages. Your patients will love the experience. Another benefit is to you, the doctor. While adjusting the cervical spine requires a fairly small amount of energy during a typically busy day, the low back is a different story.
