4. A motion assistance apparatus, comprising:
a shank frame configured to support a shank of a user;
a thigh frame comprising a first end and a second end, the thigh frame is configured to rotate relative to the shank frame, and to support a thigh of the user, and when the motion assistance apparatus is worn by the user in a standing position, the second end is a highest end of the thigh frame;
a joint rotatably coupled to a first end of the shank frame and rotatably coupled to the first end of the thigh frame;
an elongated driving frame disposed adjacent to the thigh frame and comprising a first end disposed between the first end of the thigh frame and the second end of the thigh frame and the elongated driving frame extends along a length of the thigh frame such that a second end of the elongated driving frame extends past the second end of the thigh frame, wherein the second end of the elongated driving frame is positioned at an elevation higher than the second end of the thigh frame when the motion assistance apparatus is worn by the user in the standing position, and the elongated driving frame is configured to drive the thigh frame and to assist a motion of a hip joint of the user at least by transmitting a power provided to the second end of the elongated driving frame to the shank frame via the first end of the elongated driving frame; and
a connector comprising a first end and a second end, the first end of the connector directly connected to the first end of the elongated driving frame and the second end of the connector connected to the thigh frame so that the connector is configured to transmit the power of the elongated driving frame indirectly to the shank frame via at least the thigh frame.
