Embodiments of the invention relate to walking/running braces and to devices for enhancing locomotion, specifically human bipedal locomotion. More particularly, it relates to a controlled mechanical device which provides support of the torso via the hip sockets, reduces the metabolic energy associated with walking/running and reduces the incidence of falls caused by insufficient leg thrust. Embodiments of the invention also relates to reducing the strain and metabolic energy consumption associated with walking/running with a heavy backpack or other significant carried load.
