Applied Physiology & CF

Hi,
 
I heard a story this weekend regarding a 5yr old sufferer with CF who by attending and receiving treatment from an Applied Physiology course is showing none of the normal CF symptoms (digestion / infection etc).
 
The course in question is run by a Richard Utt (www.appliedphysiology.com).
 
Unfortunatley this is all the info. I received on this and was wondering if anybody else has heard of this treatment and its success rate.
 
I am contemplating attending such course with and for my son, but it is very expensive and would like to gather as much info.on it as possible before making a desision.
 
Thanks in advance.
