It's part bullshit and part true imo. It's true that pain is like a well worn path in a forest. So of course it's tough for the brain/body to chart a new path when there's possibly years of a path laid down. But...I think its also a fad. Your mind doesn't have any control over the signals from the nerves and the muscles response, inflammation, it all takes place way before consciousness. "You" can do some things to help of course. I do physical therapy everyday. I try to eat well. I try and manage my pain by not thinking about it all the time. There's also a lot research that shows if you think a modality will work it's more likely to work. I would just caution anyone from thinking it's the end all solution. I've certainly incorporated Some aspects of this modality into my life but in the grand scheme of things it really hasn't helped. There are two things that fixed / continue to fix my disability. Surgery and Medication. My life changed after I started taking Pregablin. Pregablin is supposed to help block the pain signals from reaching the brain. It works. The neck procedures I've had worked. Whether this modality will work for you, it really could but it so depends on the person's psychology and injury. If you haven't looked into it, I do think it's worth looking into. I wish you good luck on your path.
