System and method for knee rehabilitation

1. A system for improving knee mobility after medical treatment for injury or disease, comprising:

a support mechanism disposed proximate to a surface of a floor, the support mechanism configured for receiving a user having undergone medical treatment affecting knee mobility; and

a rigid and substantially rectangular frame, said frame consisting of a top member, two side members and a bottom member arranged in a same plane to form the substantially rectangular frame, said frame having a predetermined width adapted to correspond to a waist size of the user, said top member having a padded portion, the padded portion of the top member configured for engaging a treated leg of the user at or near the popliteal space of the treated leg to support the popliteal space of the treated leg at a raised position, and said two side members terminating in bases immediately adjacent to the bottom member, the bases configured to:

provide traction between said two side members and the floor;

pivot said two side members to a plurality of angles from the floor; and

position said two side members substantially perpendicular to a thigh of the treated leg,

enabling said frame to induce a knee of the treated leg of the user to bend inwards or outwards in response to gravitational force affecting a lower portion of the treated leg.

2. The system of claim 1 , wherein the system further comprises a handheld strap configured to engage a portion of the lower portion of the treated leg of the user, the handheld strap being further configured to actuate the lower portion of the treated leg to bend the knee of the treated leg inwards in response to force applied to the handheld strap by the user.

3. The system of claim 1 , wherein the padded portion of the top member is further configured for engaging a portion of the treated leg proximate to the ankle, the padded portion further configured to support the ankle at an elevation allowing at least one of gravitational force or user force to induce extension of the knee of the treated leg.

4. The system of claim 1 , wherein the padded portion of the top member is removably attached.

5. The system of claim 1 , wherein the padded portion of the top member is translatable to a plurality of positions along the length of the top member.

6. The system of claim 1 , wherein the padded portion of the top member comprises a deformable material.

7. The system of claim 1 , wherein the bases include hinges configured to pivot the two side members to a plurality of angles with respect to the floor and allow the bases to maintain a flat contact with the floor.

8. The system of claim 1 , wherein the substantially rectangular frame has an adjustable height.

9. The system of claim 1 , wherein the substantially rectangular frame is collapsible.

10. A system for improving knee mobility after medical treatment for injury or disease, comprising:

a support mechanism disposed at an elevation in the approximate range of 15 to 40 inches from a surface of a floor, the support mechanism configured for receiving a user having undergone medical treatment affecting knee mobility, the support mechanism further configured for supporting the user in a seated position to alleviate pressure on the user's spine; and

a rigid and substantially rectangular frame, said frame consisting of a top member, two side members and a bottom member arranged in a same plane to form the substantially rectangular frame, said bottom member configured to provide structural support for said frame, said top member configured for engaging a treated leg of the user at or near the popliteal space of the treated leg to support the popliteal space of the treated leg at a raised position, and said two side members being substantially parallel to one another and terminating in bases immediately adjacent to the bottom member, the bases configured to:

provide traction between said two side members and the floor,

pivot said two side members to a plurality of angles from the floor; and

position said two side members substantially perpendicular to a thigh of the treated leg,

enabling said frame to induce a knee of the treated leg of the user to bend inwards in response to gravitational force affecting a lower portion of the treated leg.

11. The system of claim 10 , wherein the top member of the frame includes a padded portion configured for engaging the treated leg of the user at or near the popliteal space of the treated leg.

12. The system of claim 10 , wherein the system further comprises a handheld strap configured to engage a portion of the lower portion of the treated leg of the user, the handheld strap being further configured to actuate the lower portion of the treated leg to bend the knee of the treated leg inwards in response to force applied to the handheld strap by the user.

13. The system of claim 10 , wherein the bases include hinges configured to pivot the two side members to a plurality of angles with respect to the floor and allow the bases to maintain a flat contact with the floor.

14. The system of claim 10 , wherein the top member is positioned at an adjustable elevation from the floor.

15. The system of claim 10 , wherein a distance between the two side members is adjustable.

16. A method of improving knee mobility of a user having undergone medical treatment, the method comprising the steps of:

supporting the user in a seated position to alleviate pressure on the user's spine;

providing a rigid and substantially rectangular frame to support a thigh of the treated leg, said frame having a predetermined width adapted to correspond to a waist size of a user, said frame consisting of a top member, two side members and a bottom member arranged in a same plane to form the substantially rectangular, said bottom member configured to provide structural support for said frame, wherein said top member has a padded portion configured for engaging the treated leg of the user at or near the popliteal space of the treated leg to support the popliteal space of the treated leg at a raised position, and wherein said two side members terminating in bases immediately adjacent to the bottom member, the bases configured to provide traction between said two side members and the floor and pivot said two side members to a plurality of angles from the floor, positioning said two side members substantially perpendicular to a thigh of the treated leg;

engaging the treated leg of the user at or near the popliteal space of the treated leg with a portion of the padded portion of the top member of the rectangular frame; and

facilitating utilization of gravitational force to actuate a lower portion of the treated leg of the user to bend a knee of the treated leg inwards.

17. The method of claim 16 , wherein the method further includes:

applying user force to actuate the lower portion of the treated leg of the user to bend the knee of the treated leg inwards.

18. The method of claim 17 , wherein said step of applying user force to actuate the lower portion of the treated leg of the user to bend the knee of the treated leg inwards further includes:

utilizing a handheld strap, said handheld strap configured for engaging the lower portion of the treated leg.

19. The method of claim 16 , wherein

positioning said two side members substantially perpendicular to a thigh of the treated leg includes:

hingedly pivoting the two side members to a plurality of angles with respect to the floor while allowing the bases to maintain a flat contact with the floor.
