Caveat: I use “mechanics” and “movement” here interchangeably. While I appreciate that “movement” is more encompassing than “mechanics” because the former accounts for perceptual and neurophysiological inputs and outputs, “mechanics”, really positions, are less esoteric from a coaching standpoint. These positions reflect perceptual influences without having to employ something like an fMRI or PET scan. We coach with our eyes and positions or mechanics are easier to observe.

In baseball sports medicine there has existed a mythical creature known as Glenohumeral Internal Rotation Deficit (GIRD) since before I was born. It’s considered normal for throwing athletes to present with some abnormal shoulder range of motion (ROM) findings. But just how Patellofemoral Pain Syndrome (PFPS) tells me nothing more than someone’s knee hurts, GIRD simply tells me, “these shoulders don’t match.”
I don’t even want to get into defining GIRD because that’s the point of this article. It doesn’t matter and here’s why.
