Kinoped lower extremity performance improvement, injury prevention, and rehabilitation system
A ground-effect footplate against which a user applies plantar force and moves their foot in 3D across all seven lower-extremity biomechanical axes to accomplish specific as well as global ambulatory objectives related to lower extremity performance improvement, injury prevention and rehabilitation. A device comprising at least one articulating leg connected to a ground-effect footplate and a surface for a user to position against. The device can be used in conjunction with software to create virtual ambulatory environments that mimic GRFVs and cause moments of force that initiate muscular activations that substantially mimic human ambulation, and can couple those movements with non-functional movements in order to improve ROM, speed, strength, and proprioception.
1. A lower extremity exercise device comprising:
a surface configured for use with a body to position and stabilize a pelvis of the user;
at least one articulated mechanical leg connected proximally to the surface, the at least one articulated mechanical leg creates resistance on three planes, wherein the resistance is varied by a two-way communication between electronics and pneumatic valve controllers to substantially mimic ground forces during ambulation;
a footplate connected distally to the at least one articulated mechanical leg, wherein the resistance is opposed by a plantar force of the user as the user performs functional and non-functional ambulatory patterns with a foot of the user;
a first mechanism comprising pneumatic cylinders connecting the surface to a rotational mechanism providing resistance on a frontal plane;
a second mechanism comprising the at least one articulated mechanical leg, the at least one articulated mechanical leg powered by the pneumatic cylinders;
wherein the pneumatic cylinders provide resistance on a sagittal plane of the user; and
the rotational mechanism providing movement of the footplate on a transverse plane of the user.
2. The lower extremity exercise device of claim 1 , wherein the surface is a cabinet.
3. The lower extremity exercise device of claim 1 , wherein the surface is a chair.
4. The lower extremity exercise device of claim 1 , wherein the at least one articulated mechanical leg allows resistive or assistive lower extremity movement across a functional range of motion of the user.
5. The lower extremity exercise device of claim 1 , wherein the footplate maintains a stable angular position on the frontal plane and the sagittal plane relative to a longitudinal body axis of the user.
6. The lower extremity exercise device of claim 1 , wherein an angular position of the footplate is adjustable on the frontal plane and the sagittal plane relative to a longitudinal body axis of the user.

8. The lower extremity exercise device of claim 7 , wherein the software commands the electronics and the sensors to manage resistance on a plurality of planes in real-time providing user feedback and guidance.
9. The lower extremity exercise device of claim 1 , wherein the at least one articulated mechanical leg is in a parallelogram configuration.
10. The lower extremity exercise device of claim 1 , wherein the at least one articulated mechanical leg further comprises a plurality of telescoping sections.
11. The lower extremity exercise device of claim 1 , wherein one of the three planes is a frontal plane.
12. The lower extremity exercise device of claim 1 , wherein one of the three planes is a sagittal plane.
13. The lower extremity exercise device of claim 1 , wherein one of the three planes is a transverse plane.
