System and method for knee rehabilitation

1. A system for knee rehabilitation, comprising:

a rigid frame consisting of a top member and two reinforced side members including a left side member and a right side member, wherein each of the side members terminate in a base and each base terminates in a free end,

each side member extending in a straight linear fashion between a first end and its respective base, the side members connected solely by the top member extending in a straight linear fashion between the first ends, the top member arranged in a same plane with, and substantially perpendicular to, the two side members;

the top member at least partially covered by a padded portion attached thereto, the padded portion configured to engage a treated leg of a user in a seated position above a floor at or near a rear popliteal space to support a knee of the treated leg in a raised position;

and

wherein each side member includes a transition between the top member and each first end of each side member, each transition including a rubberized grip, each grip being configured for allowing the user to stabilize or position the frame relative to the floor using a hand;

the bases configured to:

1) Provide traction between the side members and the floor;

2) Pivot the side members through a plurality of angles relative to the floor;

and

3) position the side members substantially perpendicular to a thigh of the treated leg;

thus enabling the frame to induce the knee to bend inwards or outwards in response to one or more of gravitational force, user-assisted force, or user-directed force affecting a lower portion of the treated leg.

2. The system of claim 1 , wherein each of the transitions is a rounded transition.

3. The system of claim 1 , further comprising:

a strap configured to:

engage the lower portion of the treated leg;

and

actuate the lower portion of the treated leg to bend the knee inwards in response to the user-directed force applied to the strap.

4. The system of claim 1 , wherein the padded portion is further configured to:

engage a portion of the treated leg proximate to an ankle;

and

support the ankle at an elevation allowing the one or more of gravitational force, user-assisted force, or user-directed force to induce extension of the knee of the treated leg.

5. The system of claim 1 , wherein the padded portion is attached to the top member via at least one bearing, the bearing extending at least partially along the top member.

6. The system of claim 5 , wherein the bearing at least partially encloses the top member.

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

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

9. The system of claim 8 , wherein the padded portion comprises:

at least one inner layer substantially aligned with the thigh, the inner layer having a first deformability;

and

at least one outer layer disposed between the treated leg and the inner layer, the outer layer having a second deformability greater than the first deformability.

10. The system of claim 1 , wherein the height of the frame is adjustable thus enabling the frame to induce the knee to bend inwards or outwards through a range of motion based on the height of the frame.

11. The system of claim 1 , wherein the frame is collapsible.

12. A method for improving knee mobility, comprising:

supporting a user proximate to a flat surface in a seated position above the flat surface, the seated position associated with alleviating pressure on a spine of the user;

providing a rigid frame to support a thigh of a treated leg of the user, the rigid frame consisting of:

a top member and two reinforced side members including a left side member and a right side member, wherein each of the side members terminate in a base and each base terminates in a free end,

each side member extending in a straight linear fashion between a first end and its respective base, the side members connected solely by the top member extending in a straight linear fashion between the first ends, the top member arranged in a same plane with, and substantially perpendicular to, the two side members,

the top member at least partially covered by a padded portion configured to engage the treated leg at or near a popliteal space to support a knee of the treated leg in a raised position,

the bases being configured to provide traction between the side members and the flat surface and to allow the side members to pivot through a plurality of angles relative to the flat surface;

and

wherein each side member includes a transition between the top member and each first end of each side member, each transition including a rubberized grip, each grip being configured for allowing the user to stabilize or position the frame relative to the flat surface using a hand;

positioning the side members substantially perpendicular to a thigh of the treated leg;

engaging the treated leg at or near the popliteal space via the padded portion;

and

facilitating utilization of one or more of gravitational force, user-assisted force, or user-directed force to actuate at least one lower portion of the treated leg to bend the knee inwards through a range of motion.

13. The method of claim 12 , wherein facilitating utilization of one or more of gravitational force, user-assisted force, and user-directed force to actuate at least one lower portion of the treated leg to bend the knee inwards includes:

engaging the at least one lower portion via a handheld strap held by the user.

14. The method of claim 12 , further comprising:

increasing range of motion of the treated leg by lengthening the side members to increase a height of the top member relative to the flat surface.

15. A method for improving knee mobility, comprising:

supporting a user proximate to a flat surface in a seated position above the flat surface, the seated position associated with alleviating pressure on a spine of the user;

providing a rigid frame to support a thigh of a treated leg of the user, the rigid frame consisting of:

a top member and two reinforced side members including a left side member and a right side member, wherein each of the side members terminate in a base and each base terminates in a free end, each side member extending in a straight linear fashion between a first end and its respective base, the side members connected solely by the top member extending in a straight linear fashion between the first ends, the top member arranged in a same plane with, and substantially perpendicular to, the two side members,

the top member at least partially covered by a padded portion configured to engage the treated leg at or near an ankle,

the bases being configured to provide traction between the side members and the flat surface and to allow the side members to pivot through a plurality of angles relative to the flat surface;

and

wherein each side member includes a transition between the top member and each first end of each side member, each transition including a rubberized grip, each grip being configured for allowing the user to stabilize or position the frame relative to the flat surface using a hand;

positioning the side members substantially perpendicular to a thigh of the treated leg;

engaging the treated leg at or near the ankle via the padded portion; and

facilitating utilization of one or more of gravitational force, user-assisted force, user-directed force to induce extension of a knee of the treated leg.
