A system for selecting an activation of a lingual muscle of a subject, comprising: a first lead end; a second lead end; a stimulator configured to provide a stimulation to the first lead end and the second lead end; a memory system configured to store for recall a first stimulation parameter and a second stimulation parameter; a sensor configured to sense a subject and provide at least a first signal and a second signal; a processor system configured to execute instructions to: recall the first stimulation parameter and the second stimulation parameter; operate the stimulator to stimulate the subject at a first time per the recalled first stimulation parameter; operate the stimulator to stimulate the subject at a second time per the recalled second stimulation parameter; receive the first signal respective of the subject during the stimulation of the subject at the first time; receive the second signal respective of the subject during the stimulation of the subject at the second time; compare (i) the received first signal to at least one of the second signal or a predetermined signal and (ii) the received second signal to at least one of the first signal or the predetermined signal; determine a first efficacy value of the stimulation at the first time and a second efficacy value of the stimulation at the second time; and automatically select for stimulation of the subject per the recalled first stimulation parameter or the recalled second stimulation parameter based on the determined first efficacy value or the second efficacy value. a first lead end; a second lead end; a stimulator configured to provide a stimulation to the first lead end and the second lead end; a memory system configured to store for recall a first stimulation parameter and a second stimulation parameter; a sensor configured to sense a subject and provide at least a first signal and a second signal; a processor system configured to execute instructions to: recall the first stimulation parameter and the second stimulation parameter; operate the stimulator to stimulate the subject at a first time per the recalled first stimulation parameter; operate the stimulator to stimulate the subject at a second time per the recalled second stimulation parameter; receive the first signal respective of the subject during the stimulation of the subject at the first time; receive the second signal respective of the subject during the stimulation of the subject at the second time; compare (i) the received first signal to at least one of the second signal or a predetermined signal and (ii) the received second signal to at least one of the first signal or the predetermined signal; determine a first efficacy value of the stimulation at the first time and a second efficacy value of the stimulation at the second time; and automatically select for stimulation of the subject per the recalled first stimulation parameter or the recalled second stimulation parameter based on the determined first efficacy value or the second efficacy value. recall the first stimulation parameter and the second stimulation parameter; operate the stimulator to stimulate the subject at a first time per the recalled first stimulation parameter; operate the stimulator to stimulate the subject at a second time per the recalled second stimulation parameter; receive the first signal respective of the subject during the stimulation of the subject at the first time; receive the second signal respective of the subject during the stimulation of the subject at the second time; compare (i) the received first signal to at least one of the second signal or a predetermined signal and (ii) the received second signal to at least one of the first signal or the predetermined signal; determine a first efficacy value of the stimulation at the first time and a second efficacy value of the stimulation at the second time; and automatically select for stimulation of the subject per the recalled first stimulation parameter or the recalled second stimulation parameter based on the determined first efficacy value or the second efficacy value.
