Complex regional pain syndrome (CRPS) is characterised by constant regional neuropathic pain that is usually associated with abnormal sensory, autonomic, motor and/or trophic changes. Though it usually develops after trauma to a limb, in CRPS pain is disproportionate in time or intensity to the usual course of pain after injury. There are two subtypes of CRPS: in type I no overt nerve lesion ca...

Objective We present a case report of complex regional pain syndrome (CRPS) type I following total hip replacement in a patient with insulin-dependent diabetes mellitus. Discussion CRPS type 1 as a primary complication following successful hip replacement surgery has not been reported before. We would suggest that CRPS may be a possible cause of persistent pain after successful total hip replac...

Complex regional pain syndrome (CRPS), previously referred to as reflex sympathetic dystrophy, causalgia, algodystrophy, Sudeck’s atrophy and shoulder-hand syndrome, is an uncommon and poorly understood neuropathy that normally affects the limbs. CRPS is characterized by pain and altered sensation; motor dysfunction and soft tissue change; vasomotor and autonomic alterations; and psychosocial d...

BACKGROUND There is little knowledge regarding the association between psychological factors and complex regional pain syndrome (CRPS) in children. Specifically, it is not known which factors precipitate CRPS and which result from the ongoing painful disease. OBJECTIVES To examine symptoms of depression and anxiety as well as the experience of stressful life events in children with CRPS compa...

Heightened sensitivity to painful stimulation commonly spreads from the affected limb to the ipsilateral forehead in patients with complex regional pain syndrome (CRPS). In addition, acoustic startle evokes greater auditory discomfort and increases in limb pain when presented on the affected than unaffected side. In contrast, limb pain ordinarily evokes analgesia in the ipsilateral forehead of ...

Chronic complex regional pain syndrome (CRPS) is a debilitating pain condition accompanied by autonomic abnormalities. We investigated gray matter morphometry and white matter anisotropy in CRPS patients and matched controls. Patients exhibited a disrupted relationship between white matter anisotropy and whole-brain gray matter volume; gray matter atrophy in a single cluster encompassing right ...

Complex regional pain syndrome (CRPS) is a chronic pain syndrome that causes intractable pain, disability, and poor quality of life for patients. The etiology and pathophysiology of CRPS are still poorly understood. Due to a lack of proper diagnostic tools, the prognosis of CRPS is primarily based on clinical observation. The objective of this work is to evaluate a new imaging modality, photoac...

Background: Recurrent complex regional pain syndrome I is not rare in the pediatric population. The authors conducted this study to evaluate the efficacy of continuous peripheral nerve blocks with elastomeric disposable pumps associated with initial Bier blocks for the treatment of recurrent complex regional pain syndrome I in children. Methods: After parental informed consent, 13 children who ...

In 1994, a consensus group of experts gathered by the International Association for the Study of Pain (IASP) agreed on new diagnostic criteria for the reflex sympathetic dystrophy (RSD) and causalgia, and renamed them complex regional pain syndrome (CRPS) types I and II, respectively. CRPS is a complex pathophysiological entity characterised by pain, trophic and vasomotoric changes, limited fun...

This study tested for evidence supporting the clinical lore of three sequential stages of complex regional pain syndrome (CRPS) and examined the characteristics of possible CRPS subtypes. A series of 113 patients meeting IASP criteria for CRPS underwent standardized history and physical examinations to assess CRPS signs and symptoms in four domains identified in previous research: pain/sensory ...
