Abstract: The present invention relates to a method for estimating the physical activity exerted by an upper limb (10) of a person (1), the method being characterised in that it comprises the steps of: (a) Acquiring, by inertial measurement means (20) solidly attached to a forearm (11) of said upper limb (10) of said person (1), an angular speed of said forearm (11); (b) Estimating, by data processing means (21, 31, 41), a torque exerted by the muscles of an arm (12) of the upper limb (1) on said forearm (11) as a function of the measured angular speeds, of an orientation of said forearm (11), and of physical parameters of said forearm (11); (c) Determining, by the data processing means (21, 31, 41), a power exerted by the upper limb (10) as a function of the estimated torque and of the measured angular speed.

Abstract: The invention relates to a device for measuring the pinch force between a person's thumb and index finger, comprising: first and second parallel blades, said blades being disposed at a distance from one another and embedded at a first longitudinal end thereof; a sensor for measuring the pinch force exerted between the two blades at the second longitudinal end thereof, perpendicularly to the respective main planes thereof; a means for displaying the pinch force; and a means for storing and/or processing the pinch force. According to the invention, the first blade forms part of a rigid parallelepiped frame and the second blade is disposed in the space inside the parallelogram.
