Try it at home with yourself or a friend at first. That often works. If it's going to work for you, there's usually some kind of resonance -- either a sore spot on your feet in the area mapped for back, or sort of an echo between the two. If it doesn't work, you might want to seek an expert. Massage therapists and reflexologists are easier to find now than they used to be.
