There was a thing on NPR a while ago about billions paid to scam therapy centers. They would prescribe useless therapies to people with chronic back problems and other injuries. Without quality control this happens in every industry.
So... chiropractic?
Uh,I felt terrible about the whole thing, it seems like a cut and dried case of insurance fraud to me. My MD said she was sending me to physical therapy so I thought I'd be getting real treatment and didn't think about it further. I never heard of craniosacral therapy before that but it was clear that the physical therapist was practicing woo once I was actually there.
The worst thing is, since craniosacral therapy claims to treat almost every symptom and every disease she may refer 90% of her patients. :(
