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 system that creates virtual gravitational and virtual inertial performance environments with simulated ground reaction force vectors that substantially replicate or substantially modify external forces experienced during ambulation, the exercise system comprising:
a surface that stabilizes a pelvis of a user in a horizontally fixed pelvis position, the surface connected to or positioned in opposition to a footplate which delivers resistance on three planes against which a user reacts with plantar force to perform functional or nonfunctional movement patterns; and
the footplate provides simulated gravitational values and inertial values of the external forces, wherein the simulated gravitational values and the inertial values are varied to substantially mimic multiple lower extremity performance environments, including gravitational environments, and ambulation modes and speeds in a manner substantially similar to ambulation; wherein moments of force are created about all seven lower extremity biomechanical axes.
2. The lower extremity exercise system of claim 1 , wherein the footplate maintains a consistent angular position on a frontal plane and a sagittal plane relative to a longitudinal body axis.
3. The lower extremity exercise system of claim 1 , wherein the footplate varies its angular position on the frontal plane and the sagittal plane relative to the longitudinal body axis.
4. The lower extremity exercise system of claim 1 , wherein the resistance on three planes is delivered by the footplate to a plantar surface of a foot.
5. The lower extremity exercise system of claim 1 , wherein the plantar force against the footplate creates simulated ground reaction force vectors and moments of force that initiate functional kinetic chains as it moves along functional kinematic patterns.
6. The lower extremity exercise system of claim 1 , wherein the plantar force against the footplate as it moves along non-functional kinematic patterns creates ground reaction force vectors and moments of force that initiate non-functional kinetic chains.
7. The lower extremity exercise system of claim 1 , wherein the plantar force against the footplate creates functional plantar rocking as it moves along functional kinematic patterns.
8. The lower extremity exercise system of claim 1 , wherein plantar force against the footplate creates non-functional plantar rocking as it moves along non-functional kinematic patterns.
