bowen technique

i am having sessions for back ache and neck problems at the moment with a lovely gentleman who uses the Bowen Technique.

It involves small movements to realign your bones into the correct position. it is fantastic and works wonders for me.
Has anyone else tried it?

I've not heard of it but is it expensive? and is it widely available? both my dh and I have back problems. In the past I've been to a Chiropractor and he's had physio and traction;but we'd be interested in other methods
