Abstract: An orthosis for increasing range of motion of a body joint. The orthosis includes a rotational linkage mechanism having a driving link and a driven link configured for rotation about a joint axis. The driven link is selectively attachable to a body part to rotate the body part about the joint axis. A dynamic force mechanism is operatively connected between the driving link and driven link to impart a dynamic force upon the driven link when the driving link rotates relative to the driven link and the driven link resists rotation with the driving link due to a resistance force imparted on the driven link by the body part reaching a maximum range of motion. The dynamic force is transferred through the driven link to the body part.

Abstract: An ankle stretch orthosis includes a foot assembly having a ball support assembly adjustably mounted on a foot plate. The foot assembly includes an adjustment mechanism for selectively adjusting a position of ball support assembly relative to the foot plate to align the ball support assembly with a ball portion of a foot that is one of supinated and pronated.

Abstract: An orthosis for stretching tissue around a joint of a patient between first and second relatively pivotable body portions. The orthosis includes a first arm member affixable to the first body portion and including a first extension member extending therefrom. A second arm member affixable to the second body portion is also included and has a second extension member having an arcuate shape extending therefrom. A third arm member including a third extension member having an arcuate shape extending therefrom is interposed between the first and second arm members. The third arm member is operatively connected to the first and second arm members, such that the first and third arm members travel along an arcuate path defined by the second extension member when the third arm member is moved from a first position to a second position relative to the second arm member.

Abstract: The present invention provides an orthosis for stretching tissue around a joint of a patient between first and second relatively pivotable body portions. The orthosis includes a first member affixable to the first body portion and including a first extension member defining an arcuate channel therein. A second member affixable to the second body portion is also included and has a second extension member having an arcuate shape extending there from. The second extension member is operatively connected to the first extension member and travels through and within the arcuate channel, along the arcuate path, when the second arm member is moved from a first position to a second position relative to the first member.
