These results are not surprising to neurofeedback therapists. Many therapists have found that a large percentage of their patients with either fibromyalgia or chronic fatigue syndrome have suffered some form of head injury during their lifetime. Once the brain has been injured, it can become difficult for it to transition smoothly from one brainwave frequency to the next. This means that the brain is essentially "stuck in gear." If that gear happens to be one of fear or stress the patient is likely to end up feeling constantly exhausted; if it is stuck in the pain mode, as in the case of injury, fibromyalgia may result.
By far one of the most effective methods of getting the brainwaves back under control and help to shift the brain out of the patterns in which it is trapped, is neurofeedback therapy because it teaches the patient how take control of their brainwaves and manipulate them to achieve complete relaxation.
