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.
