A lower extremity exoskeleton (100), configurable to be coupled to a person, includes: leg supports (101, 102) configurable to be coupled to the persons lower limbs and designed to rest on the ground during stance phases, with each leg support (101, 102) having a thigh link (104, 105) and a shank link (106, 107) two knee joints (107, 108), each configured to allow flexion and extension between respective shank (106, 107) and thigh links (107, 108) an exoskeleton trunk (109) configurable to be coupled to the persons upper body, rotatably connectable to the thigh links (107, 108) of the leg supports (101, 102), allowing for the flexion and extension between the leg supports (101, 102) and the exoskeleton trunk (109) two hip actuators (145, 146) configured to create torques between the exoskeleton trunk (109) and the leg supports (101, 102) and at least one power unit (201) capable of providing power to the hip actuators (145, 146). In use, power is supplied to the hip actuators (145, 146) in an amount to reduce the energy consumed by a user during a walking cycle.
