Elbow Orthosis

An orthosis for stretching tissue around a joint of a patient between first and second relatively pivotable body portions, the joint and the first and second body portions defining on one side of the joint an inner sector which decreases in angle as the joint is flexed and defining on the opposite side of the joint an outer sector which decreases in angle as the joint is extended, comprising:

• a first arm member affixable to the first body portion;
• a second arm member affixable to the second body portion and including a second extension member having an arcuate shape extending therefrom;
• a third arm member interposed between the first and second arm members, wherein the first arm member is slidingly connected to the third arm member and the third arm member is operatively connected to the second extension member and travels 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;
• and a drive assembly on the third arm member, the drive assembly engaging the second extension member for selectively moving the first and third arm members with respect to the second arm member.
