Kinoped lower extremity performance improvement, injury prevention, and rehabilitation system

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.
