I don't have a reference, but several years ago I read an article that described improving one's hand-writing by engaging the entire arm up through the shoulder. The amount of movement further up the arm is small, but it transforms the overall effort. As I recall the article describing, many people "freeze up" their arm, resulting in all the effort being made in the wrist and hand. This also increases strain and fatigue.
I tried what they suggested, a few times, and it did seem to have some effect, but I didn't stick with it methodically.
Sorry not to have a reference, but maybe Google will find it, if it sounds of interest.
