Abstract: A passive exercise therapy station moves a patient's limb or body part through a prescribed range of motion without stress to the patient's limb or associated joints. A frame is formed of a pair of arches joined in parallel to one another, with a pair of overhead horizontal rails. One or more main cables extend over guide pulleys on the frame and past an adjustable guide carriage that travels along the overhead rails. An actuator positions the guide carriage at a desired location on the overhead rails. An exercise cable descends from the guide carriage to the patient. The exercise cable may be a web attached to the main cable. The exercise therapy station may be wheeled between rooms for therapy of a given patient.
