Brief summary (from the registry)
The purpose of this study is whether patients suffering from chronic back pain for more than one year will show a specific neurophysiological pattern in the EEG. This pattern is referred to as Thalamo-Cortical Dysrhythmia (TCD) and consists most likely of a self sustaining loop between the Cortex and Thalamus. This pattern has been found before in patients with very severe chronic pain. Specific lesions to the Thalamus result in a reduction of this pattern and decrease in pain. With this study the investigators will assess whether this pattern can be found in back pain patients of different types. Patients will be measured by EEG for the existence of TCD and will undergo detailed pain and psychological diagnostic.
