Yeah, and in some ways, the new study is a complete return to 150+ years ago. In the American Civil War, a theory of "windage" was put forward, that the concussion from a projectile's blast was responsible for "soldier's heart" in the head.

And don't forget the stories in the late 1800s in the UK related to "railway spine" -- the documentation of psychosomatic effects following a railroad accident, attributed to torsion of the spine and brainstem.
