Powered Orthotic Device and Method of Using Same
First Claim
1. A powered orthotic device, for use with a limb having at least two joints, the device comprising:
- a brace system including at least two brace sub-assemblies, wherein a first brace sub-assembly is operative with respect to a first one of the joints and a second brace sub-assembly is operative with respect to a second one of the joints;
wherein the first brace sub-assembly includes;
a first section and a second section, the first section and the second section configured for relative motion with respect to one another about the first one of the joints, the first brace sub-assembly configured to removably attach its first section and its second section to a corresponding limb segment, anda first powered actuator assembly (1) configured to receive a first sensor signal from an electromyographic sensor, and (2) mechanically coupled to the first brace sub-assembly so as to apply a first force for driving the first and second sections of the first brace sub-assembly to move relative to one another, the first force based on the first sensor signal;
wherein the second brace sub-assembly includes;
a first section and a second section, the first section and the second section configured for relative motion with respect to one another about the second one of the joints, the second brace sub-assembly configured to removably attach its first section and its second section to a corresponding limb segment; and
a second powered actuator assembly (1) configured to receive a second sensor signal from a sensor selected from a group consisting of an electromyographic sensor, an inertial measurement unit, and combinations thereof, and (2) mechanically coupled to the second brace sub-assembly so as to apply a second force for driving the first and second sections of the second brace sub-assembly to move relative to one another, the second force based on the first sensor signal or the second sensor signal; and
wherein the brace system and the first and second actuator assemblies form a wearable component.

Abstract
A powered orthotic device for use with a limb having at least two joints includes at least two brace sub-assemblies. The first brace sub-assembly includes a first powered actuator assembly that receives a first sensor signal from an electromyographic sensor. The first powered actuator assembly applies a first force for driving sections positioned with respect to a first joint to move relative to one another. The second brace sub-assembly includes a second powered actuator assembly that is configured to receive a second sensor signal from a sensor selected from a group consisting of an electromyographic sensor, an inertial measurement unit, and combinations thereof. The second powered actuator assembly applies a second force for driving sections positioned with respect to a second joint to move relative to one another. The second force is based on the first sensor signal or the second sensor signal.
