In my opinion, the best program for working at home on relaxation and self-regulation skills (so-called peripheral feedback, as opposed to brainwave feedback) is the Healing Rhythms program from www.wilddivine.com. It combines both Heart Rate Variability and GSR activation monitoring with many top-notch self-regulation exercises. In the office, my staff and I can teach you how to make the best use of that program in your own home.
