1. A system for assessing a patient, the system comprising:

  • a plurality of sensors, each sensor comprising a bipolar electrode, the plurality of sensors being configured for placement on a tissue surface of the patient and configured to produce signals responsive to at least EMG activity of at least one muscle proximate the tissue surface; and

    a probe comprising a flexible printed circuit board, wherein the plurality of sensors are arranged on the flexible printed circuit board in an array, the probe being configured with a size and shape to effect placement of the plurality of sensors in an oropharynx of the patient such that the plurality of sensors can detect EMG activity of the at least one muscle, the probe further comprising;

    a proximal handle; and

    a distal curved body with a convex upper surface and a concave lower surface, and wherein the plurality of sensors are located on the convex upper surface and on the concave lower surface.
