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.

Claims

13-1. An orthosis as set forth in claim 1, further comprising a knee strap affixable to the first member, wherein the knee strap is positionable about and proximal to a knee portion of the patient.

30. An orthosis for stretching tissue around an ankle joint of a patient, comprising:

a first member affixable to a lower leg of the patient;

a second member affixable to a foot of the patient, and pivotally connected to the first member;

a drive assembly on the first member, the drive engaging the second member for selectively moving the second member with respect to the first member; and

a toe orthosis affixed to the second member.

31. An orthosis as set forth in claim 30 wherein the first member includes a first extension member extending there from, the first extension member defining an arcuate main channel therein;

and

the second member includes a second extension member having an arcuate shape, wherein the second extension member is slidably positionable though the arcuate main channel of the first extension member, such that the second member travels along an arcuate path when the second member is moved from a first position to a second position relative to the first member.

32. An orthosis as set forth in claim 30 further comprising a foot plate attached to the second member.

33. An orthosis as set forth in claim 32 wherein the foot plate is slidably mounted to the second member.

34. An orthosis as set forth in claim 32 wherein the foot plate is adjustably mounted to the second arm member.

35. An orthosis as set forth in claim 34 wherein the toe orthosis is affixed to the foot plate.

36. An orthosis as set forth in claim 30 further comprising a knee strap affixable to the first member, wherein the knee strap is positionable about and proximal to a knee portion of the patient.

37. An orthosis for stretching tissue around an ankle joint of a patient, comprising:

a first member affixable to a lower leg of the patient;

a second member affixable to a foot of the patient and pivotally connected to the first member; and

a drive assembly on the first member, the drive assembly engaging the second member for selectively moving the second member with respect to the first member, the drive assembly including main, upper, and lower gears rotatably mounted in the first member, the lower gear being in engagement with the main gear, and a drive belt positioned about the upper and lower gears, such that a rotation of the upper gear results in a rotation of the main gear.

38. An orthosis as set forth in claim 37 wherein the main gear engages the second member for selectively moving the second member with respect to the first member.

39. An orthosis as set forth in claim 38 further comprising a drive knob removably attached to the lower gear.

40. An orthosis as set forth in claim 38 further comprising a drive knob removably attached to the upper gear.

41. An orthosis as set forth in claim 38 wherein the drive assembly includes:

an worm gear operably connected to the main gear; and

a drive shaft attached to and extending from the worm gear, such that a rotation of the drive shaft results in a rotation of the main gear.

42. An orthosis as set forth in claim 38 further comprising a motor operatively connected to the main gear for selectively moving the second member with respect to the first member.

43. An orthosis as set forth in claim 38 wherein the drive assembly includes a locking assembly.
