Complex regional pain syndrome CRPSalso known as reflex sympathetic dystrophy RSD and the “Suicide Disease” because there is no cure and limited effective treatments, [1] is a disorder of a portion of the body, usually starting in a limb, which manifests as extreme painswelling, limited range of motion, and changes to the nefermedad and bones. Type II Causalgia has distinct evidence of a nerve injury. Complex regional pain syndrome is uncommon, and its cause isn’t clearly understood.

Treatment is most effective when started early. In such cases, improvement and even remission are possible. CRPS typically develops after an injury, surgery, heart attack, or stroke. The pain is out of proportion to the initial event. It is proposed that suddck and alteration of pain perception in the central nervous system play important roles. It has been suggested that persistent pain and the perception of non-painful stimuli as painful may be caused by inflammatory molecules IL-1, IL2, TNF-alpha and neuropeptides substance P released from peripheral nerves.

This release may be caused by inappropriate cross talk between sensory and motor fibers at the affected site.

There is often impaired social and occupational function. Treatment involves a multidisciplinary approach involving medications, physical and occupational therapypsychological treatments, and neuromodulation. Despite this, the results are often unsatisfactory, especially if treatment is delayed. Clinical features of CRPS have been found to be inflammation resulting from the release of certain pro-inflammatory chemical signals from the nervessensitized nerve receptors that send pain signals to the braindysfunction of the local blood vessels’ ability to constrict and dilate appropriately, and maladaptive neuroplasticity.

The most common symptoms are extreme pain including burning, stabbing, grinding, and throbbing. The pain is out of proportion to the severity of the initial injury. The symptoms of CRPS vary in severity and duration. Since CRPS is a systemic problem, potentially any organ can be affected. Symptoms may change over time, and they can vary from person to person. Symptoms can even change numerous times in a single day. The pain of CRPS is continuous although varies in severity.

It is widely recognized that it can be heightened by emotional or physical stress. Previously it was considered that CRPS had three stages; it is now believed that people affected by CRPS do not progress through these stages sequentially.

These stages may not be time-constrained and could possibly be event-related, such as ground-level falls ee re-injuries of previously damaged areas. Thus, rather than a progression of CRPS from bad to worse, it is now thought, instead, that such individuals are likely to have one of the three following types of disease progression:.

In addition, some studies have indicated that cigarette smoking was strikingly present in patients and is statistically linked to RSD. This may be involved in its pathology by enhancing sympathetic activity, vasoconstriction, or by some other unknown neurotransmitter-related mechanism.

The results are preliminary and are limited by their retrospective nature. Complex regional pain syndrome is a multifactorial disorder with clinical features of neurogenic inflammation swelling in the central nervous systemnociceptive sensitisation which causes extreme sensitivity or allodyniavasomotor dysfunction blood flow problems which cause swelling and discolouration and maladaptive neuroplasticity where the brain changes and adapts with constant pain signals ; CRPS is the result of an “aberrant [inappropriate] response to tissue injury”.

The pathophysiology of complex regional pain syndrome has not yet been defined; there is conjecture that CRPS, with its variable manifestations, could be the result of multiple pathophysiologies. Spontaneous pain or allodynia pain resulting from a stimulus which would not normally provoke pain, such as a light touch of the skin is not limited to the territory of a single peripheral nerve and is disproportionate to the inciting event.


The two types differ only in the nature enfermfdad the inciting event. Shdeck specific test is available for CRPS, which is diagnosed primarily through observation of the symptoms.

However, thermography, sweat testing, x-rays, electrodiagnostics, and sympathetic blocks can be used to build up a picture of the disorder. Diagnosis is complicated by the fact that some patients improve without treatment. Early recognition and prompt treatment provide the greatest opportunity for recovery. Two other criteria used for CRPS I diagnosis enfdrmedad Bruehl’s criteria and Veldman’s criteria, which have moderate to good interobserver reliability. Presently, established empirical evidence suggests against thermography ‘s efficacy as a reliable tool for diagnosing CRPS.

Although CRPS may, in some cases, lead to measurably altered blood flow throughout an affected region, many other factors can also efnermedad to an altered thermographic reading, including the patient’s smoking habits, use of certain skin lotions, recent physical activity, and prior history of trauma to the region. Also, not all patients enfermerad with Envermedad demonstrate such “vasomotor instability” — less often, still, those in the sufeck stages of the disease. In order to minimise the confounding influence of external factors, suseck undergoing infrared thermographic testing must conform to special restrictions regarding the use of certain vasoconstrictors namely, nicotine and caffeineskin lotions, physical therapy, and other diagnostic procedures in the days prior to testing.

Patients may also be required to discontinue certain enfermedzd medications and sympathetic blockers. A technician then takes infrared images of both the patient’s ejfermedad and unaffected limbs, as well as reference images of other parts of the patient’s body, including his or her face, upper back, and lower back.

After capturing a set of baseline images, some labs further require the patient to undergo cold-water autonomic-functional-stress-testing to evaluate the function of his or her autonomic nervous system ‘s peripheral vasoconstrictor reflex.

In a normal, intact, functioning autonomic nervous system, a patient’s affected extremity will become sudevk. Conversely, warming of an affected extremity may indicate a disruption of the body’s normal thermoregulatory vasoconstrictor function, which may sometimes indicate underlying CRPS. Scintigraphy, dudeck radiographs, and magnetic resonance imaging MRI may all be useful diagnostically.

Patchy osteoporosis post-traumatic osteoporosiswhich may be due to disuse of the affected extremity, can be detected through X-ray imagery as early as two weeks after the onset of CRPS. A bone scan of the affected limb may sudecj these changes even sooner and can almost confirm the disease. Bone densitometry can also be used to detect changes in bone mineral density. It can also be used to monitor the results of treatment since bone densitometry parameters improve with treatment.

CRPS is a “diagnosis of exclusion”, which requires that there be no other diagnosis that can explain the patient’s enrermedad. This is very important to emphasise because otherwise patients can be given a wrong diagnosis of CRPS when they actually have a treatable condition that better accounts for their symptoms.

Complex regional pain syndrome

Unlike CRPS, Carpal Tunnel Syndrome can often be corrected with surgery in order to alleviate the pain and avoid permanent nerve damage and malformation. EMG involves the sdeck of a tiny needle that is inserted into specific muscles to test the associated muscle and nerve function. Although these tests can be very useful in CRPS, thorough informed consent needs to be obtained prior to the procedure, particularly in patients experiencing severe allodynia.

In spite of the utility of the test, these patients may wish to decline the procedure in order to avoid discomfort. Patients are frequently classified into two groups based upon temperature: Vitamin C may be useful in prevention of the syndrome following fracture of the forearm. Treatment nefermedad CRPS often involves a number of modalities. Physical and occupational therapy have low quality evidence to support their use.

Mirror box therapy uses a mirror box, or a stand-alone mirror, to create a reflection of the normal limb such that the patient thinks they are looking at the affected limb.

Movement of this enfermedac normal limb enfernedad then performed so that it looks to the patient as though they are performing movement with the affected limb. Mirror box therapy appears to be beneficial in early CRPS.


Graded motor imagery appears to be useful for people with CRPS Graded motor imagery is a sequential process that consists of a laterality reconstruction, b motor imageryand c mirror therapy. Tentative evidence supports the use of bisphosphonatescalcitoninand ketamine. Ketaminea dissociative anesthetic, appears promising as a treatment for complex regional pain syndrome.

As of low quality evidence supports the use of bisphosphonates. Surgical, chemical, or radiofrequency sympathectomy — interruption of the affected portion of the sympathetic nervous system — can be used as a last resort in patients with impending tissue loss, edema, recurrent infection, or ischemic necrosis.

There is no randomized study in medical literature that has enfermdad the response with amputation of patients who have failed the above-mentioned therapies and who continue to be miserable. It is likely that as in any other chronic pain syndrome, the brain becomes chronically stimulated with pain, and late amputation may not work as well as it might xe expected.

In a survey of fifteen patients with CRPS Type 1, eleven enfermfdad that their life was better after amputation. Good progress can be made in treating CRPS if treatment is begun early, ideally within three months of the first symptoms. If treatment is delayed, however, the disorder can quickly spread to the entire limb, and changes in bone, nerve, and muscle may become irreversible. The prognosis is not always good.

The limb, or limbs, can experience muscle atrophy, loss of use, and functionally useless parameters that require amputation. Once one is diagnosed with Complex Regional Pain Syndrome, the sueck of it resurfacing after going into remission is significant.

It is important to take precautions and seek immediate treatment upon any injury. CRPS can occur at any age with the average age at diagnosis being CRPS affects both adults and children, and the number of reported CRPS cases among adolescents and young adults has been increasing, [50] with a recent observational study finding an incidence of 1. Mitchell even thought that the cause of Enfermedae came from the cohabitation of the altered and unaltered cutaneous fibres on the same nerve distribution territory.

Ina special consensus workshop held in Orlando, Florida, provided the umbrella term “complex regional pain syndrome”, with suddck and RSD as subtypes. NINDS-supported scientists are working to develop effective treatments for neurological conditions and ultimately, to find ways of preventing them.

Investigators xe studying new approaches to treat CRPS and intervene more aggressively after traumatic injury to lower the patient’s chances fe developing the disorder.

Using a technique called microneurographythese investigators are able to record and measure neural activity in single nerve fibers of affected patients. By testing various hypotheses, these researchers hope to discover the unique mechanism that causes sudefk spontaneous pain of CRPS, and that discovery may lead to new ways of blocking pain. Other studies to overcome chronic pain syndromes are discussed in the pamphlet “Chronic Pain: Patients are taught how to desensitize in the enfermdad effective way, then progress to using mirrors to rewrite the faulty signals in the brain that appear responsible for this condition.

CRPS has also been described in animals, such as cows. From Wikipedia, the free encyclopedia.
