I came across an interesting discussion about biofeedback in the journal called Biofeedback. I have experience with biofeedback and have discussed some of this here http://www.teethremoval.com/biofeedback.html.
The article presents the narrative of a young cellist who is able to realize the potential of his talent and also able to eliminate migraine headaches.
William, the name young musician described in the article, sought relief from migraine headaches that were affecting him almost daily. His therapy, however, did not take the approach of treating the headaches, but of focusing on William as a person and as a performer. By improving his functionality, working through moments of obsessiveness, self-criticism, fear, and anxiety, the headaches could also be resolved.
William used sensors to read his brainwaves using software which gave feedback to the brain through a visual display and sound. This technology is able to help people past that moment when they obsess over whether they have given the correct answer or hit in this case played the right musical note. Neurofeedback, guided imagery, and coaching about decisions was able to help William move beyond the difficulties he encountered. During his senior recital in college, he was able to give a relaxed, confident performance that was met with a standing ovation.
It is possible that biofeedback and neurofeedback training can help people improve their performance. In additional many stress reduction tools such as mental imagery training can also be used to hep people better achieve positive results.
I am not quite sure how many people have used biofeedback before but it may be something to consider especially if you suffer from persistent headaches.
