More danger of anthropomorphism

Those of you who read this blog--thanks for your time--know that I am concerned about how we assume that therapeutic interventions used with humans are being taken without translation into the animal therapy world. I call this "anthropomorphism".
The latest trend in this has been in the idea of "core" muscular strength as a deterrent to back pain in humans. This idea is now being promoted in the equine world. There are now such things as equine "pilates" that are pilates in use of the name only. It is a sad situation to me, that two medical professionals decided that a series of stretches, using enticements like reaching for a carrot, to get the horse to move in a non-traditional way is the same as Pilates. This is an obvious rip off of a branded name.
But beyond this there is still the problem of taking the concepts of "core" strength and equating it to something useful for the equine, when, in fact, it is still a controversy in the human context as pointed out in this NY Times Article: http://well.blogs.nytimes.com/2009/06/17/core-myths/?em
Let me get off my soap box and state that anytime we humans or our animals can be encouraged to perform non-traditional movements our body will benefit from it. Getting up from the computer and stretching, teaching your horse carrot stretches or better yet clicker, taking your dog for a swim will all tend to increase the options for movement available to the body. Increasing the movement options--or as Rolfers say "adaptive capacity"--allows the body to choose from a greater repetoire of movements to remain energetically efficient.
Any thoughts?
