BioTENS is a compact, Ultra-Low Frequency, Transcutaneous Electrical Neural Stimulator (ULF-TENS). This ULF-TENS delivers a precisely regulated, bilaterally simultaneous, rhythmic stimulus to both the masticatory and the facial muscles. Based on a patent issued in 1984, a single pair of electrodes (without the need for any ground) provides gentle stimulation, mediated* through the fifth (Vth) and seventh (VIIth) cranial nerves, such that the benefits are received by the entire masticatory and facial musculature.
When BioTENS is used to relax muscles prior to taking a clinical bite registration, it is possible to observe the effect of the ULF-TENS on the muscles by recording the electrical activity with an electromyograph (BioEMG II). The BioEMG II can show the levels of activity before and after the TENS pulsing. Many pain patients exhibit more muscle activity before pulsing and less activity after pulsing.
