| Research Abstract |
To accomplish the goal-directed pointing task, at the first step visual and somatosensory information from the hand should be integrated to allow accurate recognition of the position of the hand in space and at the final step the relative spatial relationship between the hand and the target should be visually fine-tuned for accurate performance of the movement. We revealed that the accuracy of pointing movement of the complex regional pain syndrome (CRPS)-affected limb tended to be impaired under the light condition. However, motor disturbance of the affected limb seen under the light condition was not observed in the dark. These results suggest that the motor disturbance of the CRPS-affected limb would be attributable to impaired function of the central nervous system, especially impairment of perception of the spatial position of the CRPS-affected limb based on the visual and somatosensory information.
