“Vibroacoustic therapy (VAT) is a type of sound therapy that involves passing pure low frequency sine wave vibrations into the body via a device with embedded speakers.[1][2] This therapy was developed in Norway by Olav Skille in the 1980s.[3] The Food and Drug Administration has approved vibroacoustic therapy for increasing circulation, pain relief, and increasing mobility.[4] Vibroacoustic therapy is being evaluated to treat a number of conditions including fibromyalgia,[5] cerebral palsy[6] and Alzheimer’s Disease.[7]” Wikipedia
