The PainEraser 1 is a special adapter that turns the PE Driver (sold separately) into a High Frequency Vibrational Tissue Release (HFVTR) device that quickly and durably releases painful muscle spasm and connective tissue contraction. HFVTR was researched by neurologist Paul Nogier. He found a spectrum of frequencies (6000 to 12,000 oscillations per minute) to mechanically release scar tissue and extinguish the neurological reflexes that cause muscle spasm and tightness. The only competing HFVTR device is very expensive, awkwardly designed, and operates at only one speed. The PainEraser 1 can be used to treat within the full therapeutic frequency range discovered by Nogier, and all at a fraction of the price of the competing single speed device, which does NOT provide the whole therapeutic HFVTR frequency range discovered by Nogier.
