Abstract: | OBJECTIVE: To evaluate clinical prognostic factors of complex regional pain syndrome type I (CRPS I) in patients with stroke in an attempt to improve the Perrigot score, which does not include shoulder subluxation, unilateral neglect, or depression. DESIGN: This was a prospective study. The initial clinical data (first month) included motor index, Ashworth scale, de Bats score for shoulder subluxation, Montgomery-Asberg Depression Rating Scale, and sensory disorders evaluation. The prognosis of CRPS I was evaluated from the Perrigot score. A score of CRPS I severity was measured on entry and 3 mo later. RESULTS: Of the 71 patients with hemiplegia who were included, 34.8% had a CRPS I. The five main clinical factors in the prognosis of CRPS I were motor deficit, spasticity, sensory deficits, and initial coma. The prognostic score of Perrigot was strongly correlated with the CRPS I severity and was predictive of subsequent progression. CONCLUSION: Shoulder subluxation, unilateral neglect, and depression did not seem to be determinant predictive factors of CRPS I severity. |
