Why is that absurd? my chiropractor is doing it with me and it's been working fine - he adjust all extremities too - he's terrific and I don't think it is absurd at all. I came to him 2 weeks ago in extreme pain and couldn't sit for even a second without the pain increasing threefold - now I am 80% better and even sat without pain for 30 minutes today.
I don't think it's good to generalize like that - are you a chiropractor?
