Once the sensory receptor is stimulated by the injury pain is initiated, i.e. the electrical signal from the site of stimulus is sent to the brain. This study proposes the use of an electroencephalogram (EEG) as an index for self-controlling of the acute pain via the EEG biofeedback system. Relationship between the EEG signal and the levels of pain is investigated. Once the acute pain is occurred, experimental results illustrate that alpha (8-13 Hz) frequencies decrease as well as the beta (20-25 Hz) frequencies increase in the posterior areas. This index can be further used for the acute pain control system in our ongoing study. The success of this technique would lead to the reduction of using the medicine for real-time controlling of the acute pain.
