She does not mention the CCSVI theory, that the true cause of MS is a blood reflux which injures the brain and spinal cord, but in truth I believe she is treating herself for CCSVI in two critical ways.
1) Her nutritional therapy serves two purposes: A) It prevents stress on the vascular system caused by food intolerances and toxins and B) it heals damaged tissue while optimizing brain health.
2) The EMS electrical stimulation on her back is "balancing" the Chinese Bladder Meridian which runs down the back and stimulates blood circulation.
Apparently she is one of those MS patients (myself included) who does not need angioplasty to open a blocked vein. I believe the various vein abnormalities (wall membrane too thin?) can be more subtle than a mechanically treatable stenosis. Blood circulation can be restricted by a weakened vein which narrows intermittently or collapses because of stress and can be kept open without angioplasty by removing the stress (e.g.glutens, aspartame, mercury fillings, cold, flus, toxins, ambition) and enhancing blood circulation (EMS electrical stimulation, massage, acupuncture, kinesiology, osteopathy, swimming.) For these patients toxic MS drugs may aggravate the problem. Individual solutions for the venous blood circulation problem can be as varied as the multiple stress factors which
trigger it. That is why what works for one MS patient may not work for another.
Everyone can benefit from optimal nutrition. But some MS patients may actually have a "blocked" vein which cannot be relieved solely through Dr. Wahls program. And it should be recognized that she is in fact treating CCSVI.
She, like many MS patients, probably does not have a CCSVI structural vein stenosis and cannot benefit from angioplasty.
