Belated thanks for the helpful posts above, which gave me some important questions to ask when my mom and I had a consult with an MD who does PEMF. Long story short, he said there would probably be some benefit but he couldn't guarantee it and he couldn't say how much, so at a cost of more than $1000, we weren't ready to take the plunge.

soccertese, the drug regimen that you follow is similar to the one my mom follows, but her respiratory dyskinesias have become pretty unbearable. Her neuro prescribed amantadine, but it is making it hard for her to walk -- it looks like she has aged 15 years in one week! Anyway, the quest continues...

Best wishes.
