Patent ID: 8636627

Claim:
A lower-limb training apparatus that implements off-axis functional motions of a user, said lower limb training apparatus comprising: a sagittal plane exercise machine for major lower limb movement within a human sagittal plane in use, and a mount for an off-axis movement mechanism; an off-axis movement mechanism coupled to said mount for performing a secondary off-axis motion of the lower limbs, and a footplate arranged to hold a user's foot and coupled with the off-axis movement mechanism wherein said off-axis movement mechanism comprises at least one of: (1) a pivoting mechanism that includes a disk arranged to rotate about a tibial rotation axis of a user, wherein said secondary off-axis motion comprises a pivoting perturbation of said footplate and guides internal/external tibial rotation of the user's foot while said footplate moves in the direction of said major lower limb movement in the sagittal plane; (2) a sliding mechanism that includes a mediolateral slider wherein said secondary off-axis motion comprises a sliding movement of said footplate and guides a frontal plane sliding motion of the user's foot while said footplate moves in the direction of said major lower limb movement in the sagittal plane.
