Abstract:
1. An apparatus for therapeutically treating and/or training lower extremities of a person, the apparatus comprising: a frame including a pair of side-by-side linear guides; a pair of retainers that each secure one extremity of the person and are movable independently of each other along walking trajectories; a pair of driven controllable motion devices each associated with one of the linear guides, wherein each of the motion devices includes first and second carriages disposed in one of the linear guides and movable along that linear guide in a horizontal direction, and including an arm connected to one of the retainers and pivotably attached to the first carriage such that rotation of the arm relative to first carriage causes a corresponding retainer to vertically raise, wherein the arm is connected to the second carriage via a connecting element and wherein the first and second carriages are moveable relative to each other within the linear guide such that movement of the first carriage towards the second carriage causes the rotation of the arm; a pair of first linear drives each associated with one the motion devices for changing a longitudinal position of corresponding first and second carriages within a corresponding linear guide; a pair of second linear drives each associated with one of the motion devices, each of the second linear drives being connected to corresponding first and second carriages for transferring motion from the first carriage to the second carriage and for changing the relative position between the first and second carriages to rotate a corresponding one of the arms, wherein the first linear drive forms a main drive that moves both carriages and the second linear drive relative to the frame; and a pair of a rotary drives each disposed on one of the arms for changing inclination of a respective retainer.
