Device for quantifying finger independence

摘要

The device (D) has a module including a receiving structure (S) for subassemblies (S1), where each subassembly includes a sleeve (6) for passage of a piston (7). A piston position preset by a screw allows non-isometric measurements during movement of the piston. Isometric measurements are taken during blocking of the piston in a position made by a maximum compression of a return unit. A contact is provided between the piston and a disk mounted above a sensor by screwing the screw until obtaining a contact between a flat end of the screw and an upper face of the disk relative to the sensor.
