초록/요약
Objective: To investigate altered prefrontal white matter integrity in complex regional pain syndrome (CRPS) and its relation with the degree of pain catastrophizing. Design: Cross-sectional study. Setting: University hospital. Participants: Twenty-one CRPS patients and 49 patients without CRPS (N=70). Interventions: Not applicable. Main Outcome Measures: The fractional anisotropy values within the prefrontal regions reflecting the structural integrity of white matter were measured in CRPS patients and patients without CRPS using diffusion tensor imaging. The degree of pain catastrophizing was also evaluated in CRPS patients. Results: The structural integrity of the prefrontal white matter was lower in CRPS patients than in patients without CRPS (P=.03). In addition, lower structural integrity in the prefrontal cortex was correlated with a higher degree of pain catastrophizing among CRPS patients (r= −0.54, P=.01). Conclusions: Our findings suggest that pain catastrophizing, which is frequently reported in patients with CRPS, may be associated with the dysfunction of the prefrontal white matter. © 2020 American Congress of Rehabilitation Medicine
