AbstractThe cognitive-evaluative (C-E) dimension of pain is commonly observed in patients with a relatively long duration of pain. However, little is known about the effects of pain relapse on the C-E dimension of pain. Moreover, the improvement process of the C-E dimension of pain following treatment is unknown. The objective of this case report was to (a) demonstrate that the C-E dimension was affected in the acute phase of neuropathic pain in cases of pain relapse, and (b) demonstrate the improvement process of the C-E dimension of pain. A woman was diagnosed with low back pain (LBP) and sciatica. The patient had previously experienced symptoms of LBP and sciatica; thus, this episode was a case of pain relapse. At the beginning of rehabilitation, the C-E dimension of pain was present in addition to the sensory-discriminative (S-D) dimension of pain. It was observed that improvement of the C-E dimension of pain was delayed in comparison with that of the S-D dimension of pain. The C-E dimension of pain was observed with pain relapse even though it was in the acute phase of pain. This case provides a novel insight into the C-E dimension of pain. Moreover, the delay in improving the C-E dimension of pain indicates a difference in the improvement process for each pain dimension.
