Claim:
1. A motorized device for training the lower limbs of a subject, the device comprising a pair of articulated systems (ASs), intended to form an interface with said subject, wherein each of said articulated systems comprises a base, a foot support assembly and a framework for said foot support assembly, wherein: said framework comprises two longitudinal, articulated subassemblies, a main subassembly and a supporting subassembly, said base comprises a support or carrier structure on which two rail track sections, a first rail track section and a second rail track section, are fixed, wherein a first cart is guided on said first rail track section and a second cart is guided on said second rail track section; said base further comprises a first driving screw and a second driving screw, wherein said first driving screw is arranged to drive said first cart and said second driving screw is arranged to drive said second cart; a first motor is arranged to rotate said first driving screw and a second motor is arranged to rotate said second driving screw, wherein rotation of said first and second driving screws results in linear movement of said first and second cart, respectively; wherein said motorized device further comprises: a third motor acting on a transmission assembly, wherein said transmission assembly is adapted to transmit a rotational movement of said third motor to said foot support assembly, wherein said foot support assembly is pivotally connected to said main subassembly, wherein said third motor is directly mounted, or directly mounted via a motor mount, on said first cart and in that said transmission assembly comprises a plurality of pairs of co-rotational belt pulleys, and a plurality of driving belts acting on said belt pulleys, wherein a rotational movement from said third motor on said first cart propels the rotation of a motor pulley, and wherein rotation of said motor pulley is transmitted via a first belt to a first pair of pulleys of said transmission assembly.
