Complex Regional Pain Syndrome (CRPS), characterized by severe pain and swelling, and changes in the skin on affected limb, is intractable pain for long-term after injury. Because the diagnostic criterias of CRPS are very broad , it is difficult to select effective treatments for CRPS in clinical. Previous reports showed that patients with CRPS neglect affected limb (decline of body-specific attention) and hyperattention is directed to the space where the affected limb is placed. However, there is no report that both body-specific attention to affected limb and spatial attention to the affected space were measured at the same time. Other studies showed that mental rotation and prism adaptation tasks reduced pain of CRPS probably due to modulating body-specific attention and spatial attention. Therefore, in this research, we investigate the relationship between changes of body-specific and spatial attention and change of the pain in CRPS by using psychophysiological methods.

In mental rotation task, the patient sits on the chair in front of PC on the table and watch image of either left or right hand rotated at 0-360 degrees on the PC display. The patients perform will be asked to judge of either left or right hand against the hand picture diplayed, and then to push the button of either left or right by unaffected finger. The patients perform 4 sessions (96 trials in a session) and it takes about 16 minutes to complete this intervention.
The patients perform the mental rotation task first for two weeks (five times a week, ten times in total). After two weeks, they perform prism adaptation task for two weeks.
In prism adaptation task, the patients wear the prism glasses which change visual angle from left to right or right to left. The patients who wear the glasses sit on the chair in front of PC with touch-panel display on the table. When visual stimulus appears on the display at random location in the monitor, they directly push the visual stimulus by unaffected finger. One set of this task take about four minutes and they perform four sets.
The patients perform the prism adaptation task first for two weeks (five times a week, ten times in total). After two weeks, they perform mental rotation task for two weeks.
