I think my best reply would be to post a paragraph from a recommendation from one of the vets who has attended the EPT course. As I said in another post vets and farriers don't have a handle on this unless they have bothered to look at other sports as the research has outstripped the delivery of the information.
The vet below had an enquiring mind and was not quite happy with the results of traditional treatments so wanted to study under Professor Bowker as she had seen his published work and thought it important. Many vets don't have the time or inclincation to look at new research.

The Diploma of Equine Podiotherapy is much more than a "how to trim a hoof" course. We have learnt how to assess the whole horse, and apply the hoof care most appropiate. As a vet, it has given me an additional treatment option especially for those previously frustrating cases and hoof care now forms part of my treatment plan. I know WHAT to do, WHY it needs to be done and can simply explain it to the client from a scientific basis, and HOW to carry it out. It has really filled in the gap between vet and hoof care, and the horses and clients are seeing the benefits.

As for the question about EPT being impressive. I have not seen one single shod horse that has not improved with this type of trimming. Thats why I feel its so important for it to become well known especially in the race industry where the greatest amount of hoof deformation occurs.
Some motherhood statements here. 
I doubt any sensible person would not accept that the care and condition of a racehorse's feet are critical to its performance on the track.
The question is whether "equine podiotherapy" is in fact a science that provides quantifiable benefits, or just another one of those practices that sounds impressive, but which in reality does nothing to improve the animal's health and well-being.
I'd expect that today's vets and professional farriers have a good handle on things. Happy to be educated otherwise if that's not the case.
