Upon polysomnographic examination, the subject was diagnosed with positional preference obstructive sleep apnea syndrome (OSAS), with 70% of episodes occurring while the patient was in the supine position (Figure 1).
Application of TENS electrodes. (a, b) The two TENS electrodes are placed bilaterally over the cutaneous projection of the fifth pair of cranial nerves notch, which is located between the coronoid and condylar processes. (c) A third grounding electrode is placed in the center of the back of the neck.

Tukwila, WA) generated a repetitive, synchronous, and bilateral stimulus through pulsed currents delivered at 1.5 s intervals and a frequency of 0.66 Hz. The two TENS electrodes (Myotrode SG Electrodes , Myotronics-Noromed Inc., Tukwila, WA) were then placed bilaterally over the cutaneous projection of the fifth pair of cranial nerves notch, which was located between the coronoid and condylar processes. This location was determined by manual palpation of the zone anterior to the tragus (Figures 2(a) and 2(b)). A third grounding electrode was placed in the center of the back of the neck (Figure 2(c)).
