Moving control of the mouse is most efficient in what is known as the precision grip (Napier, 1956) where index finger and thumb work closely together, and not by moving the whole arm from the shoulder (as in many so-called ergonomic mouse designs). The use of a precision mouse can also result in less muscle strain in the forearms because this involves less wrist extension (Kotani & Horii, 2003, Ulmann, et al., 2003).
