Can it be done without a doctor?
Definitely. If it was unsafe, we wouldn't be offering this service online. But during the several years that we have practiced these exercises, we haven't had a SINGLE case when a person got worse. This refers both to people who visited our hospital in Perm and to those who communicated with us via e-mail and snail mail.
In fact, the exercises are almost impossible to do in such a way as to bring harm. The way they work guarantees that you will improve your health, not damage it. Of course, everything could be possible (in theory), but in practice we have yet to see someone who manages to do hurt one's health with these techniques.
We have taught parents who then did the exercises with their children. Even with kids, there have never been any problems. Sometimes the changes in health were slow, but they were always positive.
