Older horses(horses older than 6 yrs.old) with negative plane coffin bones, especially behind, need wedging and support for the internal structures. Time after time it has been demonstrated that when this is done, the horse returns to full soundness and the HP/CBA is restored and maintained. And, when this support is removed, the internal spatial orientation of p3 returns to a negative plane and various and sundry pain and unsoundness issues resurface.
Now, I realize that the plural of anecdote is not, data, but there you have it none the less
