EDSS as a sole or main measurement of MS severity was discredited a long time ago, so why should it suddenly be the only measure of improvement after any kind of treatment? That would be absolutely foolish, something that would be done only by a technician who has no real understanding of the great disability and reduction in quality of life caused by fatigue, cog-fog, bladder problems, pain, etc.
In my case, my EDSS has improved a bit since liberation, enough that now I use my cane only in places like airports (until the the procedure I was steadily getting worse, using the cane everywhere, expecting to be in a wheelchair soon). However, it has been the tremendous improvement in energy levels that has made the biggest change in my quality of life. Of course, the only "objective" measure for that symptom is that I have no or only one nap a day instead of four, but since that is a consistent improvement that has endured for over ten months, I feel safe to say that it is not only because I had a good night's sleep. In fact, my sleep patterns don't appear to have changed (except that I may be waking up more refreshed).
In fact, self-reported results on
http://www.ccsvi-tracking.com do show that over 50% of liberated people do see some improvement in EDSS, but even if that were not the case, saying the CCSVI procedure should be dismissed if it doesn't improve EDSS in everyone is just plain uninformed.
