1. A portable device for quantifying movements of pronation and/or supination of a person, and intended to be used when the person has an elbow on a horizontal support, the portable device comprising:
a solid armature comprising:
means for attaching, configured to secure one hand of the person in the device, during the movements of pronation and/or supination;
a central pivot element intended to be in contact with the horizontal support, during angular oscillations of the hand,
between two opposed identical first block angles relative to a vertical position called neutral position, the first block angles being defined between the solid armature and the horizontal support and
the first block angles defining a small amplitude,
first means for blocking the movement of pronation and the movement of supination of the elbow, at the two first block angles; and
second means for blocking the movement of pronation and the movement of supination,
at two identical opposed second block angles relative to the neutral position, between the solid armature relative to the horizontal support,
the second block angles defining a large amplitude greater than the small amplitude; and
an Inertial Measurement Unit (IMU) configured to measure movement data, wherein the solid armature consists of a frame with: two parallel principal parts with rigid bars mounted perpendicularly to two parallel transversal parts with transversal rods, the means for attaching being mounted on the parallel transversal rods.
