Abstract: A powered orthotic device includes a brace having a first section and a second section, the first section and the second section operationally coupled at a pivot, the first and the second sections moving about the pivot to define flexion and extension directions, such directions defining inside and outside regions of the brace respectively. The device further includes at least one set of straps that removably attach the first section and the second section to a corresponding limb segment such that the pivot is proximate to a joint between each limb segment.

Abstract: A method of providing rehabilitation movement training for a person suffering from nerve damage, stroke, spinal cord injury, neurological trauma or neuromuscular disorder in attempting to move a body part about a joint using a powered orthotic device includes sensing at least one electromyographic signal of a muscle associated with motion about the joint, applying in a first direction with respect to the joint a force having a magnitude that is a first function of the at least one sensed electromyographic signal, and applying in a second direction with respect to the joint a return force that is a second function of the at least one sensed electromyographic signal, wherein the second function differs from the first function.
