“hands on the forehead with some light pressure and then you're moving your head up ever so slightly there's a lot of patience when they do this make them such a an amount of effort in the beginning that they kind of clench to stay there and patients who have that habit from before they can they can do this without it being visible so you're not going to see them doing this it looks perfectly fine but they're clenching to stay there”

“if there's resistance it means they're clenching to stay there so you have to kill them to stop doing that so they want to employ minimal effort to stay in beautiful posture”
