Descriptive Pilot Study of the Effects of a Standardized Neuromodulation Program on Cortical Brain Function in Chronic Low Back Pain Patients

"20 sessions of neurofeedback of 5 minutes each consisting of :~* The patient is equipped with an electroencephalography headset. The feedback visual has the form of a candle flame and is modulated by alpha synchrony.~* The height of the flame is proportional to the intensity of the patient's pain. The patient has to concentrate on the height of this flame by thought to modulate it and, at the same time, to decrease the intensity of his own pain."

The patient in alpha synchrony related state and in rating state will undergo an fMRI
