    Abstract: A lower extremity orthosis, including at least one actuator configured to control a motion of at least one joint of a person wearing the orthosis, is provided with a handle including a force sensor configured to produce a signal representing a force applied to the handle. A controller, which is in communication with the force sensor and the at least one actuator, is configured to modify the motion based on the signal from the force sensor. The system can be particularly employed to enable a physical therapist to have input in controlling and modifying the positions and/or forces prescribed by the lower extremity orthosis during rehabilitation of the person.

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