Diagnosing Obstructive Sleep Apnea Using Electromyography of the Muscles of the Mouth

The transmembranous electromyography (tmEMG) probe is a disposable single-use bipolar recording device with the sensor configured with two electrodes located at the distal end of the probe in a parallel orientation. Unlike conventional EMG probes that are designed to be inserted into the muscle, the tmEMG probe is placed on the surface of the muscle similar to a surface electrode; the tip of the probe is approximately the size of a ball point pen, which allows us to record from the smaller muscles inside the mouth. Recordings will be taken from the genioglossus and palatoglossus in the mouth bilaterally. Recordings will be taken while the subject performs various maneuvers such as shallow breathing, deep breathing, and pressing their tongue against the side of their mouth.
