The device for quantifying the independence of the fingers, comprising a plurality of pistons inserted in a receiving structure and allowing a digital support of the fingers of one hand except the thumb and subject to a displacement against means of reminders for contacting force sensors transmitting information to a recording computer unit, characterized in that the module is in the form of a module for manipulation by a patient user and held in the palm of the hand, said module comprising a receiving structure (S) of subassemblies (S1), each subassembly being arranged vertically and comprising a sleeve (6) with fixed position internally hollow for the passage of a piston (7). , said piston being mounted to slide freely in the sleeve and being hollow and internally threaded for receiving a piston adjusting screw (8) with respect to a sensor element (10), underlying position, and this against a means of return and compression (9), and in that the position of the piston preset by the screw (8) allows non-isometric measurements to be made during the displacement of the piston, and isometric measurements during the locking in position of the piston produced either by the maximum compression of the return means (9) and thus the contact between the piston (7) and the disc (11) mounted above the sensor (10). ) or by screwing the adjusting screw until the contact between the flat end of the screw and the upper face of a disc (11) in relation to the said sensor (10).Le dispositif pour quantifier l'indépendance des doigts, comprenant une pluralité de pistons insérés dans une structure réceptrice et permettant un appui digital des doigts d'une main à l'exception du pouce et soumis à un déplacement à l'encontre de moyens de rappels pour être en contact avec des capteurs de force transmettant des informations à une unité informatique d'enregistrement, se caractérise en ce que le module est établi sous forme d'un module destiné à être manipulé par un patient utilisateur et tenu
