Orthosis for gait modulation
First Claim
1. An apparatus, comprising:
- a first orthosis layer configured to substantially envelop a portion of a limb, the first orthosis layer including a retention portion and a mounting portion, the retention portion configured to retain the first orthosis layer about the portion of the limb, the mounting portion configured to be coupled to an electrical stimulator;
a second orthosis layer coupled to an inner surface of the first orthosis layer, the second orthosis layer configured to be coupled to a surface electrode, the first orthosis layer and the second orthosis layer collectively configured such that the surface electrode is disposed at a predetermined position overlying a peroneal nerve of the limb when the first orthosis layer and the second orthosis layer are disposed about the portion of the limb; and
a connector assembly configured to electrically couple the electrical stimulator to the surface electrode, at least a portion of the connector assembly configured to be disposed within a connector opening defined by at least one of the first orthosis layer or the second orthosis layer.

Abstract
A functional electrical stimulation (FES) orthosis, including: a frame, an inner layer coupled to an inner surface of the frame, an electrode base, and a connector assembly. The frame is configured to substantially envelop a limb, and includes a retention portion configured to retain the frame about the limb, and a mounting portion configured to be coupled to an electrical stimulator. The electrode base is coupled to the inner layer, and is configured to couple a surface electrode to the inner layer. The frame and the inner layer are configured such that the electrode base is disposed at a predetermined position relative to the limb. The connector assembly is configured to electrically couple the stimulator to the electrode base. At least a portion of the connector assembly is disposed within a connector opening defined by the frame.

17. An apparatus, comprising:
-
a frame assembly configured to substantially envelop a portion of a limb, the frame assembly including a retention portion and a mounting portion, the retention portion including a first member and a second member, an end portion of the first member spaced apart from an end portion of the second member to define an opening through which the portion of the limb is disposed when the frame assembly is being donned, the mounting portion configured to be coupled to an electrical stimulator; an electrode base coupled to an inner surface of the frame assembly, the electrode base configured to couple a surface electrode to the inner surface, the frame assembly configured such that the electrode base is disposed at a predetermined position overlying a peroneal nerve when the frame assembly is disposed about the portion of the limb; a connector assembly configured to electrically couple the stimulator to the electrode base, at least a portion of the connector assembly disposed within a connector opening defined by the frame assembly; and a fastening strap configured to be coupled across the opening to secure the frame assembly to the portion of the limb, the first member and the second member collectively configured to substantially retain the frame assembly about the portion of the limb before the fastening strap is coupled across the opening. - View Dependent Claims (18, 19, 20, 21, 22)
