The present invention relates to a two-degree-of-freedom planar rehabilitating, monitoring and/or evaluating device comprising a first guiding mechanism (2), a second guiding mechanism (3), substantially parallel to the first guiding mechanism (2), a third guiding mechanism (4), substantially perpendicular to the first and second guiding mechanisms (2, 3), and an end-effector (5), wherein the third guiding mechanism (4) is connected to the first and second guiding mechanisms (2, 3), and wherein the end-effector (5) is connected to the third guiding mechanism (4). The present invention also relates to a two-degree-of-freedom planar rehabilitating, monitoring and/or evaluating interactive device adapted for rehabilitation, monitoring and/or assessment of the upper limbs of a subject, comprising said device.
