We worked on use of biofeedbsck. They monitored brainwave activity and we worked to achieve a mental state where we subconsciously ignored or stopped feeling the pain. By thinking in certain patterns or concentrating on objects we were able to move pain from conscious memory to an area where we just forgot about it. It involved some hypnosis but what I remember was it worked. The program was run by doctors and psychologists. This was what went through in 1974.
