After many methods of evaluation of the hand function, this last one does not neet any measuring of angle nor length because the hand is its own system of reference : the thumb is the scale for the measurement of the flexion and the plane of a table for the extension. The measurements are noted from 5 to 1, from the best to the worst function : so the best hand obtains the best score. The evaluation of the grip between palm and fingers needs cylinders of specified diameters corresponding with common things as pencil or knitting needle, but it is possible to use the opposite hand instead. Adding the measurement of the opposition, it is possible at the end of the examination to fill a hand global function form easy to enter in a computer. The advantage of this method is that it evaluates the result from the patients' point of view : that is to say in terms of different types of grip. It is a global and functional evaluation, easy to use in any circumstances, but other more precise methods may be employed simultaneously for special cases such as results in tendon or joint reconstruction. © 1988 Société d'Édition de l'Association d'Enseignement Médical des Hôpitaux de Paris.
