If the electrical stimulation is effective, I would say it would probably be preferable to most drug therapies since just about all drugs have serious side-effects when taken over a lifetime - certainly mainstream rheumatoid arthritis drugs like Prednisone can have horrific side-effects.
They're also very, very expensive.
C diff, Lysteria, and Salmonella... Oddly, ecoli doesn't appear on the list. See table #2 & #3
I'm sure there are many patients who would be happy for a more cost effective option.
Interesting question is whether they then need to go through the process of FDA/similar approval. The cost savings aren't as simple as just creating the chemical structure... We are talking about immunoglobulins
Something new with few side effects might help lots of people avoid surgery.
I have been on a TNF-a inhibitor for over a year and the results thus far have been literally life changing - for the better. I haven't been this healthy or had this much energy since before adulthood.
