Reply to comment by peanutbutterwife in Researchers have discovered a new situation from the everyday environment where our crucial ability to perceive what is truly vertical is compromised: when our body pitches (body pitch) and moves at the same time (body motion) by giuliomagnifico

I am a physical therapist but haven't ever heard it called that.

What is it usually called?

We simply refer to it as LOB, loss of balance and the attempt to regain midline either balance or equilibrium reaction. I can see how the term pitch could fit the action of being displaced.

In this study it doesn't seem like a sudden unexpected change in displacement but a response to the incline which we'd usually call a righting reaction, assuming that is what they mean by pitch in the study. Trying to confirm so I know I'm understanding it correctly.

edit: rereading it I believe by body pitch they mean the extent the person is leaning backwards so their head/upper body is posterior to the vertical axis. That would make sense since they used the dental chair to create "pitch" without movement.

I added this edit if you didn't see it:
