Method of using powered orthotic device
First Claim
1. 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, the method comprising:
- 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, via an actuator having a rotational energy output coupled to the device at a location proximate to a portion thereof adjacent 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.

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.

-
sensing an electromyographic signal of a muscle associated with motion about the joint; applying in a first direction with respect to the joint, via an actuator having a rotational energy output coupled to the device at a location proximate to a portion thereof adjacent to the joint, a force having a magnitude related to a magnitude of the sensed electromyographic signal; and applying in a second direction with respect to the joint a return force in the absence of a sensed electromyographic signal of the muscle. - View Dependent Claims (12, 13, 14, 15, 16, 17)
