I tore my medial meniscus recently and am now using an Otto 128 three times daily when I apply arnica on my injured knee. It remains an important healing tool in my recovery process and is ideal for travel which is imminent. I was able to use my new weighted planetary forks to help a nurse’s aid with a migraine, give some relief to a friend suffering from Parkinson’s, and help relax his partner, all one day after returning home. Yesterday I brought the Mode set of five forks with me for a monthly program I offer at our local nursing and rehab center. This is a wonderful octave set that when brought close to the ears of each individual I could see their entire facial expression relax, that includes the smiles on two deaf people. I have had many successes with Biosonic Tuning Forks and cannot imagine life without a few for daily use.
