ABSTRACT:
An apparatus for stretching a joint of the human body (such as a knee joint) is disclosed. This apparatus contains an extension harness, a line cord, a first guide for the line cord which preferably is attached to the harness (such as grommets in the harness or pulley blocks attached to the harness), a second guide for the line cord (such as a pulley system, or an eye hook), and an anchor. When the harness secured around a patient's knee and attached to an anchoring surface, movement of the line cord causes movement of the harness.
