Prognosis

CRPS can be divided into acute and chronic forms, with a reasonably good prognosis in the first year, but a poorer prognosis thereafter.[115][116]

In a population-based study, type 1 CRPS resolved in 74% of patients, most within the first year, including many who received no specific intervention.[4] This suggests that spontaneous resolution may be more common than previously thought. Outcome was not associated with age, sex, or affected site, but the best resolution rate was associated with occurrence following fractures (91%).[4] One review concluded that, for patients with long-lasting type 1 CRPS, there is insufficient evidence to draw conclusions regarding prognosis.[117] Subsequent reviews of CRPS suggest that prognosis is not as poor as commonly assumed.[51][118]
