My wife and I have received benefit from the use of the Infratonic machine. One treatment relieved low back pain for my wife. She is a teacher and has found that using the Infratonic machine on her feet after work sooths her tired feet, and helps her to sleep well. And, I have an old knee injury, which was recently re-injured. I used the Infratonic on my knee one night and the pain was gone the next day. I have also used the Infratonic machine on my chest to strengthen my immune system. I have found the added benefit of a good night’s sleep. I am currently using the machine on the dan dien point to strengthen my internal organs, and plan to use it to promote calm in my ten month old child as she goes through the teething process.
