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 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.
Claims19
A device for increasing the range of motion of a joint, comprising:
- a first arm member including a first extension member extending therefrom;
- a first support member affixable to the first arm member, wherein the first support member is affixable to a first body portion;
- a second arm member including a second extension member having an arcuate shape extending therefrom, the second extension member is operatively connected to the first extension member so that relative movement between the first and second affixable members is determined by movement along the arcuate shape;
- and
- a second support member articulatingly mounted to the second arm member, the second support member including a sliding base member slidably mounted to the second arm member;
- a fixed base plate fixed to the sliding base member;
- and a pivotable base plate pivotably connected to the fixed base plate such that the pivotable base plate can arcuately pivot with respect to the fixed base plate and the second arm member,
- wherein the second support member is affixable to a second body portion and wherein the joint is interposed between the first and second support members.
A device for increasing the range of motion of a joint, comprising:
- a first arm member including a first extension member extending therefrom;
- a first support member affixable to the first arm member, wherein the first support member is affixable to a first body portion;
- a second arm member including a second extension member having an arcuate shape extending therefrom, the second extension member is operatively connected to the first extension member so that relative movement between the first and second affixable members is determined by movement along the arcuate shape;
- and
- a second support member articulatingly mounted to the second arm member, wherein the second support member is affixable to a second body portion;
- the joint is interposed between the first and second support members;
- the arcuate shape of the second extension member is a cam surface, and wherein the first extension member comprises cam followers that control the relative movement between the affixable members.
