Neurofeedback is the biofeedback modality most commonly used to treat traumatic brain injury. It is almost always the case that mild TBI is the level seen by the private practitioner; severe cases of brain injury are usually not treated with neurofeedback, although there are exceptions (Larsen, 2009).
Thatcher (1999, 2000) advocates obtaining a quantitative electroencephalograph (QEEG) in order to determine which of the 2500 variables to focus on with respect to the neurofeedback. When the problematic sites are identified, these variables become the focus of targeted treatment. The QEEG then can be a means of scientifically noting progress in the TBI patient.
One interesting form of neurofeedback is called HEG biofeedback. This type of biofeedback trains the patient to increase their cerebral blood flow in the frontal lobe, and this is very helpful for most people who have had traumatic brain injury. In fact, this kind of biofeedback also helps with attention problems, headaches and depression.
