BACKGROUND: Complex regional pain syndrome (CRPS) is a painful and disabling condition that usually manifests in response to trauma or surgery. When it occurs, it is associated with significant pain and disability. It is thought to arise and persist as a consequence of a maladaptive pro-inflammatory response and disturbances in sympathetically-mediated vasomotor control, together with maladaptive peripheral and central neuronal plasticity. CRPS can be classified into two types: type I (CRPS I) in which a specific nerve lesion has not been identified, and type II (CRPS II) where there is an identifiable nerve lesion. Guidelines recommend the inclusion of a variety of physiotherapy interventions as part of the multimodal treatment of people with CRPS, although their effectiveness is not known. OBJECTIVES: To determine the effectiveness of physiotherapy interventions for treating the pain and disability associated with CRPS types I and II. SEARCH METHODS: We searched the following databases from inception up to 12 February 2015: CENTRAL (the Cochrane Library), MEDLINE, EMBASE, CINAHL, PsycINFO, LILACS, PEDro, Web of Science, DARE and Health Technology Assessments, without language restrictions, for randomised controlled trials (RCTs) of physiotherapy interventions for treating pain and disability in people CRPS. We also searched additional online sources for unpublished trials and trials in progress. SELECTION CRITERIA: We included RCTs of physiotherapy interventions (including manual therapy, therapeutic exercise, electrotherapy, physiotherapist-administered education and cortically directed sensory-motor rehabilitation strategies) employed in either a stand-alone fashion or in combination, compared with placebo, no treatment, another intervention or usual care, or of varying physiotherapy interventions compared with each other in adults with CRPS I and II. Our primary outcomes of interest were patient-centred outcomes of pain intensity and functional disability. DATA COLLECTION AND ANALYSIS: Two review authors independently evaluated those studies identified through the electronic searches for eligibility and subsequently extracted all relevant data from the included RCTs. Two review authors independently performed 'Risk of bias' assessments and rated the quality of the body of evidence for the main outcomes using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. MAIN RESULTS: We included 18 RCTs (739 participants) that tested the effectiveness of a broad range of physiotherapy-based interventions. Overall, there was a paucity of high quality evidence concerning physiotherapy treatment for pain and disability in people with CRPS I. Most included trials were at 'high' risk of bias (15 trials) and the remainder were at 'unclear' risk of bias (three trials). The quality of the evidence was very low or low for all comparisons, according to the GRADE approach.We found very low quality evidence that graded motor imagery (GMI; two trials, 49 participants) may be useful for improving pain (0 to 100 VAS) (mean difference (MD) -21.00, 95% CI -31.17 to -10.83) and functional disability (11-point numerical rating scale) (MD 2.30, 95% CI 1.12 to 3.48), at long-term (six months) follow-up, in people with CRPS I compared to usual care plus physiotherapy; very low quality evidence that multimodal physiotherapy (one trial, 135 participants) may be useful for improving 'impairment' at long-term (12 month) follow-up compared to a minimal 'social work' intervention; and very low quality evidence that mirror therapy (two trials, 72 participants) provides clinically meaningful improvements in pain (0 to 10 VAS) (MD 3.4, 95% CI -4.71 to -2.09) and function (0 to 5 functional ability subscale of the Wolf Motor Function Test) (MD -2.3, 95% CI -2.88 to -1.72) at long-term (six month) follow-up in people with CRPS I post stroke compared to placebo (covered mirror).There was low to very low quality evidence that tactile discrimination training, stellate ganglion block via ultrasound and pulsed electromagnetic field therapy compared to placebo, and manual lymphatic drainage combined with and compared to either anti-inflammatories and physical therapy or exercise are not effective for treating pain in the short-term in people with CRPS I. Laser therapy may provide small clinically insignificant, short-term, improvements in pain compared to interferential current therapy in people with CRPS I.Adverse events were only rarely reported in the included trials. No trials including participants with CRPS II met the inclusion criteria of this review. AUTHORS' CONCLUSIONS: The best available data show that GMI and mirror therapy may provide clinically meaningful improvements in pain and function in people with CRPS I although the quality of the supporting evidence is very low. Evidence of the effectiveness of multimodal physiotherapy, electrotherapy and manual lymphatic drainage for treating people with CRPS types I and II is generally absent or unclear. Large scale, high quality RCTs are required to test the effectiveness of physiotherapy-based interventions for treating pain and disability of people with CRPS I and II. Implications for clinical practice and future research are considered.

Complex regional pain syndrome (CRPS) is the current consensus-derived name for a syndrome usually triggered by limb trauma. Required elements include prolonged, disproportionate distal-limb pain and microvascular dysregulation (e.g., edema or color changes) or altered sweating. CRPS-II (formerly "causalgia") describes patients with identified nerve injuries. CRPS-I (formerly "reflex sympathetic dystrophy") describes most patients who lack evidence of specific nerve injuries. Diagnosis is clinical and the pathophysiology involves combinations of small-fiber axonopathy, microvasculopathy, inflammation, and brain plasticity/sensitization. Females have much higher risk and workplace accidents are a well-recognized cause. Inflammation and dysimmunity, perhaps facilitated by injury to the blood-nerve barrier, may contribute. Most patients, particularly the young, recover gradually, but treatment can speed healing. Evidence of efficacy is strongest for rehabilitation therapies (e.g., graded-motor imagery), neuropathic pain medications, and electric stimulation of the spinal cord, injured nerve, or motor cortex. Investigational treatments include ketamine, botulinum toxin, immunoglobulins, and transcranial neuromodulation. Nonrecovering patients should be re-evaluated for neurosurgically treatable causal lesions (nerve entrapment, impingement, infections, or tumors) and treatable potentiating medical conditions, including polyneuropathy and circulatory insufficiency. Earlier impressions that CRPS represents malingering or psychosomatic illness have been replaced by evidence that CRPS is a rare complication of limb injury in biologically susceptible individuals.

Several definitions and sets of diagnostic criteria of complex regional pain syndrome have been proposed, but to date none has been accepted completely. This article presents a specific subtype of the disease, called 'chronic, refractory complex regional pain syndrome' which is extremely severe, disabling and resistant to treatment. It also emphasizes difficulties with diagnosing complex regional pain syndrome because of its variable clinical presentation and diagnostic criteria being insufficiently precise. The necessity to distinguish between criteria for clinical use and for scientific purposes is suggested with a proposal of practical guideline for diagnosing acute complex regional pain syndrome. A review of treatments for complex regional pain syndrome is presented, with opinion on their effectiveness: good in an early stage, less well in chronic and generally poor in the chronic, refractory subtype.

The diagnosis and management of complex regional pain syndrome is often challenging. Early diagnosis and intervention improve outcomes in most patients; however, some patients will progress regardless of intervention. Multidisciplinary management facilitates care in complex cases. The onset of signs and symptoms may be obvious or insidious; temporal delay is a frequent occurrence. Difficulty sleeping, pain unresponsive to narcotics, swelling, stiffness, and hypersensitivity are harbingers of onset. Multimodal treatment with hand therapy, sympatholytic drugs, and stress loading may be augmented with anesthesia blocks. If the dystrophic symptoms are controllable by medications and a nociceptive focus or nerve derangement is correctable, surgery is an appropriate alternative. Chronic sequelae of contracture may also be addressed surgically in patients with controllable sympathetically maintained pain.

Multidisciplinary pain management clinics provide the standard of care for the diagnosis, evaluation, and treatment of patients who have chronic pain. Primary care physicians are encouraged to maintain an active role in the care of patients after referral to these pain centers, often for long-term opiate therapy or complex regional pain syndrome. Insights into the role of pain management clinics after referral are discussed in this article.

OBJECTIVE: The object of this study is to evaluate the importance of a correct timing for surgery, the different strategies of therapy and the use of the neuromodulation in the Complex Regional Pain Syndrome (CRPS) type II. PATIENTS AND METHODS: The last 2 years we observed 8 patients with the clinical picture of a CPRS type II, due to previous peripheral nerve lesions of the upper extremity. All the patients followed a therapeutic protocol of neuromodulation and reconstructive surgical repair. RESULTS: Six patients out of eight had almost a complete recovery of the symptoms 6 months after the surgery. CONCLUSIONS: Our study demonstrates that the patients who underwent surgical repair followed by neuromodulation didn't present any recurrence of the symptoms.

The challenge to understand reflex sympathetic dystrophy/complex regional pain syndrome may require a better understanding of the complex relationship between the central and peripheral nervous systems. There is no comprehensive hypothesis that clearly explains the etiology and no uniformly successful treatment method. This brief summary of the challenge reviews some of what is known, hypothesizes a possible etiologic mechanism, and proposes 10 common-sense principles for management that recognizes the handicap of limited knowledge.

Complex Regional Pain Syndrome (CRPS) Types I and II are characterized by various combinations of sensory, autonomic and motor abnormalities. Pain disproportionate to the severity and duration of the inciting event is the most devastating symptom. In animal studies, conditions resulting in exaggerated pain states demonstrate elevated pro-inflammatory cytokines. In addition, pro-inflammatory cytokines have been shown to induce or increase neuropathic and inflammatory pain. Utilizing high sensitivity enzyme linked immunosorbent assay (ELISA), we compared the levels of the pro-inflammatory cytokines interleukin-1beta (IL-1beta), interleukin-6 (IL-6) and Tumor Necrosis Factor-alpha (TNF-alpha) in the cerebrospinal fluid (CSF) of patients afflicted with CRPS to CSF levels found in other patients with and without painful conditions. The results from this study demonstrated significant increases in IL-1beta and IL-6, but not TNF-alpha in the CSF of individuals afflicted with CRPS as compared to controls. CSF cytokine levels in controls with painful conditions did not differ from levels in controls without pain. These increases showed no correlation with the patient's gender or weight. These results are consistent with studies that suggest that the pathogenesis of CRPS is due in part to central neuroimmune activation.
