An active orthotic device, e.g. a hand orthosis, is attached to one or more limbs of a human subject and comprises a respective set of actuators () for moving a respective limb (A) among the one or more limbs. A method for controlling the orthotic device comprises obtaining one or more bioelectric signals, [S(t)], from one or more bioelectric sensors () attached to or implanted in the human subject; processing the one or more bioelectric signals, [(t)j, for prediction of an intended application force, FA(t), of the respective limb (A) onto an object; obtaining a force signal, PA(t), from a force sensing device () associated with the respective set of actuators () and/or the respective limb (A); and generating, as a function of a momentary difference, e(t), between the intended application force, FA(t), and the force signal, PA(t), a respective set of control signals, it(t), for the respective set of actuators ().

Control of an active orthotic device

The invention relates to a device () for pivoting an arm () relative a joint (). The device comprises at least one artificial tendon () attached to a distal end () of the arm and a driving mechanism (), the driving mechanism being connected to and adapted to pull the tendon and the distal end of the arm, and a method of operating the device.
