Quadra-TENS

QuadraTENS was designed in 2006 for medical and dental applications. It is a two-channel ULF TENS, which is the same as the BioTENS. Two channels allow you to relax two sets of muscles at the same time.

However, the QuadraTENS also offers a “burst” mode, which produces an increased contraction without the extra “shock” inherent in the single high amplitude spike required for an equivalent degree of muscle contraction. The burst mode is optimized to increase the effectiveness of ULF-TENS, especially when applied to larger muscles, such as the trapezius.

An optional pair of electrodes, placed bilaterally on the posterior triangle of the neck, provides stimulation of the eleventh (XIth accessory) cranial nerve, which contains the motor fibers to the trapezius and sternocleidomastoid muscles. Alternatively, the electron pair can also be placed directly above the motor point of the trapezius.

Thanks to the 28 millisecond delay between channels, the QuadraTENS completely eliminates crossover current between channels and provides a masking function, which is very useful for patients sensitive to craniofacial TENS stimulation. Unlike medications, ULF-TENS therapy has no side effects (nausea, fatigue, dependence, etc.). Over the past twenty years, many clinicians and patients have found TENS therapy to be remarkably helpful in managing facial, head, and neck pain.
