This article made me conscious of my use of the mouse: I realize that I move it only with a ~3cm square, which allows to reach all corners of the screen by only moving my fingers, while the base of my palm stays "locked" to the desk. When using multiple screens, the mouse does some quick hops to reach them, but almost never leaves that square.<p>This requires configuring the mouse to have sufficient "speed". I've never had any musculoskeletal disorder, probably thanks to making such small moves with my hand and staying relaxed.
