| Research Abstract |
The purpose of the study was to develop neuropsychological tests to evaluate pain, and other sensation and perception, in migraine patients and patients with phantom limb pain. We also tried to identify visual stimuli which cause or relive their pain, and develop techniques to relieve their pain from psychological approaches. Our study suggested that migraine patients are hypersensitive to luminance contrast, especially with certain spatial frequencies in natural scenes. Our study also showed that the use of colored filters may help their reading. Mirror therapy was effective in a patient whose upper left limb was amputated more than 30 years ago, and his "vividness of sensation" in his left arm recovered from proximal to distal.
