Mendoza et al. (2009) introduced a coin rotation task as a convenient test of motor dexterity. it involves timed completion of twenty 180° rotations of a nickel using the thumb, index, and middle fingers. research participants' results on the coin rotation task are compared with their results on a test of grip strength — a measure of another construct: global upper-extremity strength. the correlation between the coin rotation task and the grip strength task were found to be not statistically significant.
