29.11.10 - Development of a severity score for CRPS
Recently a study was conducted to evaluate the validity and utility of a continuous type score to index severity of CRPS. Psychometric and medical evaluations were performed in 114 CRPS patients and 41 non-CRPS patients. Based on the presence or absence of 17 clinically-assessed signs and symptoms of CRPS, an overall CRPS Severity Score (CSS) was derived. Results indicate that the CSS corresponds with and complements currently accepted dichotomous diagnostic criteria for CRPS, and support its validity as an index of CRPS severity.
