Concussion of forces? When one force meets another force, the stronger force will prevail. This is how an adjustment works. The 'force' of the subluxation (its resistance or inertia) meets the 'force' of an adjustment (not a forceful adjustment...a specific adjustment applied with the perfect amount of force needed for that specific person). If the 'force' is applied precisely and with focus, then the patient benefits and the subluxation is reduced. As BJ Palmer said, "it is as simple as that!"
