Abstract

SUMMARY: In complex regional pain syndrome (CRPS), functional imaging studies gave evidence for an important role of the central nervous system (CNS) in the pathogenesis of the disease. Especially, reorganization in central somatosensory and motor networks was demonstrated, leading to an altered central processing of tactile and nociceptive stimuli, as well as to an altered cerebral organization of movement. These findings may explain a number of clinical signs and symptoms occurring in the course of the disease and seem to be closely related to chronic pain in CRPS. Neurorehabilitative strategies, which target cortical areas and aim to restore impaired sensorimotor function in patients with CRPS, therefore, may be effective not only in restoring impaired function but also in pain reduction. This article reviews findings of functional imaging studies, which have been conducted to clarify CNS involvement in the course of CRPS.

  1. A, Contrast map of the general linear model (GLM) calculated by subtracting the tapping condition of controls (right hand) from the tapping condition in patients (CRPS-affected side [ie, right hand]). Brain sections are referred to by the superior-inferior level in millimeters relative to a line through the anterior and posterior commissure. Z-score indicates level of significance. B, Contrast map of the GLM calculated by subtracting the tapping condition on the unaffected side (ie, left hand) from the affected side (ie, right hand) in patients with CRPS. Brain sections are referred to by the superior-inferior level in millimeters relative to a line through the anterior and posterior commissure. Z-score indicates level of significance. C, Implementation of the individual degrees of motor impairment (z-values of tapping frequencies [ie, values of the individual maximum tapping frequencies normalized to the mean maximum tapping frequencies of controls]) as regressors in the GLM model for the condition "tapping on the CRPS-affected side." With this approach, brain areas correlating with the degree of motor impairment are isolated. Key areas of activations are indicated according to the following abbreviations: SFC indicates superior frontal cortex; MFC, middle frontal cortex; IFC, inferior frontal cortex; AIP, anterior intraparietal area, MIP, medial intraparietal area; mtc, middle temporal cortex; loc, lateral occipital complex.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
