First Claim
1. An orthosis for flexing tissue about a joint of a wearer, the orthosis comprising:
- a first arm member configured to couple to a first body portion of the wearer;
a second arm member coupled to the first arm member, the second arm member configured to couple to a body portion of the wearer;
a positioning assembly including a gear, the positioning assembly coupled to the first arm member and configured to move the first arm member relative to the second arm member to any one of a plurality of discrete angular positions; and
a spring configured to provide a dynamic force to the joint when the first member is in any one of the plurality of discrete positions.

Abstract
The present disclosure provides an orthosis for stretching tissue around a joint of a patient between first and second relatively pivotable body portions flexing tissue about an arm joint of a wearer. 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. The second extension member is operatively connected to the first extension member and travels through the first extension member along an arcuate path when the second arm member is moved from a first position to a second position relative to the first arm member configured to couple to a first arm portion of the wearer, a second arm member pivotably coupled to the first arm member, the second arm member configured to couple to a second arm portion of the wearer, and a drive assembly coupled to the first and second arm members and configured to move the first arm member in an arcuate path.

15. A method of using a device for flexing tissue about a joint of a body portion of a wearer, comprising:
-
providing a device for flexing tissue about a joint of a wearer, the device comprising; a first member configured to couple to a first body portion of a wearer; a second member configured to couple to a second body portion of a wearer, the second member coupled to the first member at a device pivot connection; a positioning assembly including a gear, the positioning assembly coupled to the first arm member and configured to move the first arm member relative to the second arm member; and a spring member configured to move from a first position to a second position to provide a dynamic force to the joint; coupling the first arm member to the first body portion of the wearer; and coupling the second arm member to the second body portion of the wearer; and
operating the positioning assembly to move the first arm member relative to the second arm member to move the spring member from the first position to the second position.
