<p>A passive exerciser is used for the treatment of the ankle. It comprises a holding frame (2) having a calf support (3) and a foot support (4). The foot support (4) can be pivoted relative to the calf support (3) by means of a pivoting motor drive (9) for dorsal extension (raising of the foot) and plantar flexion (lowering of the foot). For pronation (raising of the lateral margin of the foot) and supination (raising of the medial margin of the foot) there is provided a further pivoting motor drive (8) located between the foot support (4) and a pivoting bracket (7) connected to the calf support (3). The position of the pivot axes (10, 13 and 13a) is suited to the course of the movement axis of the upper ankle, on the one hand, and of the lower ankle, on the other hand. <IMAGE></p> |
