1. A system for treating obstructive sleep apnea (OSA) in a subject, the system comprising:
a power source;
an electromyogram (EMG) sensor configured to detect muscle activity of a muscle that controls tongue movement;
a neuromuscular stimulator configured to be in electrical communication with the power source, the neuromuscular stimulator comprising an array of electrodes configured to stimulate distal arborizing branches of a hypoglossal nerve of the subject;
a controller programmed to deliver a therapy signal to the array of electrodes, in response to muscle activity detected from the EMG sensor, to stimulate the distal arborizing branches of the hypoglossal nerve to open an oropharyngeal airway of the patient.
