yes Uri , it is necessary to cause a little pain in the process of reducing the muscular tightness attendant to Wikipedia reference-linkfacet joint immobility. This pain is however a very usefull guide in the course of reducing tone . As the pain is felt at the first attempt to move it presents as an indicator firstly that these muscular( and of course inflammatory ) tone increases are present. As mobilisation is continued, through a range that is acceptable and often quite enjoyable to the patient, the pain reduces as the muscles relax as the resistance to that passive movement decreases. At this point it can be obsereved that freedom of movement has been gained actively as well. Further mobilisation to adjacent joints continues the process untill there is no more to treat , or my time is up ( treatment times are 45 minutes ). Inflammatory change will disappear over the following 24 hours , in direct relation to the amount of joint freedom induced. These are permanent changes. The next steps are to undo whatever attendant dural tightness may have been aquired. In this way the strong likelihood of referred events are also undone. In the course of many thousands of treatments over nearly 20 years I have found that referred events are far more common than many have previously thought. So much so that I was moved to share this information with the likes of colleagues, friends, the general public and yes even the members of my local coven where I regularly bite the heads off live chickens.
Try hard to keep the debate lively Uri , though you would be wise to add more sagacity and less of the sneering know it all fumbling name calling. Listen carefully and even you may learn something of value.I do think however you are more inclined to watch and call from the sidelines than add something of value here.
Oh and by all means have the last word, I can't wait.
