Patty,
I have used The IDN approach for many years with different forms of dystonia and even spoke at the dystonia conference a few years back. It has a progressive build up effect by addressing the peripheral manifestations of the central disorder. By improving the peripheral environment they tend to feel better and even move better but this does take time and the effect is temporary as the central disorder takes over. Cervical dystonia is under dx yet IDN has a dramatic effect on this population but they require on going care. I even had a spasmotic torticollis (right looker) did extremely well with pain and increased function but could not turn his head any further than the day he walked in. I helped with all the aspects that caused the pain which allowed his function to improve without in any way changing the root cause, this is where DN fits in with this population
