Just now saw John's link for one such program in FL. 

In my working life as a Speech/Language Pathologist, I was privileged to witness the amazing results of Hippotherapy with cerebral palsy afflicted kids, Autistic children and adults, behavioral disorders and children with fetal alcohol syndrome. 

There's no doubt this type of therapy would benefit many of our vets with PTSD and various other related traumatic injuries.

Here is LINK  to the AHA site showing the certified therapists in each state.

Most of the hippotherapists I knew were not only skilled in the techniques but also in the navigation of the various bureaucratic paperwork necessary to get folks the help.

Gene I had to look that up, never heard of it before. Thats cool therapy.

Like herb, I didn't recognize the name but I have seen stories about the successfulness of these programs.  Personally believe you are correct in saying that this type of therapy would be very helpful to those struggling with PTSP and similar disorders. 

There are several hippotherapists in AZ. I'm writing one inquiring about the possibilities. Maybe, we can put some therapists and various vet organizations together.
