Complex regional pain syndrome (CRPS) is a chronic pain condition often involving hyperalgesia and allodynia of the extremities. CRPS is divided into CRPS-I and CRPS-II. Type I occurs when there is no confirmed nerve injury. Type II is when there is known associated nerve injury. Female gender is a There is mixed evidence that vitamin C reduces the risk of CRPS after a fracture. 22, 23 Medications often used to treat neuropathic pain, such as anticonvulsants (e.g., gabapentin [Neurontin Complex Regional Pain Syndrome (CRPS) is a neuropathic pain disorder characterized by ongoing pain disproportionate to the degree of tissue injury and persists beyond the usual expected time for tissue healing. [1] Pain is accompanied by sensory, motor, and autonomic abnormalities. Such abnormalities include allodynia, hyperalgesia, sudomotor and vasomotor abnormalities, and trophic changes We would like to show you a description here but the site won’t allow us. Anti-convulsant drugs such as gabapentin have demonstrated evidence of effectiveness in providing pain relief in acute and chronic neuropathic are commonly used as part of the pharmacological management of CRPS [64, 65]. Physical therapy (PT) and occupational therapy (OT) can improve outcomes in CRPS, when started early (symptoms for less than 1 year). 3 Objectives of PT and OT in CRPS are to improve range of motion, desensitization, minimize swelling, promote normal positioning, decrease muscle guarding, and increase functional use of the extremity. 4 INTRODUCTION. Complex regional pain syndrome (CRPS) remains a relatively mysterious chronic pain disorder, usually affecting a single limb and characterized by pain in an area of the limb or limbs that is disproportionate in time or degree to the usual course of any known trauma or other lesion. [90, 91] A randomized, double-blind, placebo-controlled trial showed that gabapentin was mildly beneficial for pain and sensory symptoms in CRPS type I. Gabapentin has been shown to be effective in treating other neuropathic pain conditions, such as diabetic neuropathy and postherpetic neuralgia. This type of therapy uses a mirror to help trick the brain. Sitting before a mirror or mirror box, you move the healthy limb so that the brain perceives it as the limb that is affected by CRPS. Research shows that this type of therapy might help improve function and reduce pain for those with CRPS. Transcutaneous electrical nerve stimulation Overall, evidence is considered insufficient for use of gabapentinoids for CRPS-related pain. However, three randomized controlled trials (RCTs) did find gabapentin to result in significant improvement in pain whereas one RCT reported use of amitriptyline to be equally as effective as gabapentin. Lastly, prevention of CRPS following injury or trauma is an area currently being studied with evidence for vitamin C showing potential efficacy.⁵⁻⁷. Non-Conventional Treatments for CRPS: What the Data Reveal Gabapentin. Gabapentin is an anti-epileptic drug used for chronic pain management, specifically neuropathic pain. While the There are indications that gabapentin administered at doses of 600 to 1800 mg every 24 hours in the first eight weeks can cause some reduction in pain symptoms suffered by patients with CRPS-I. There is limited evidence that gabapentin reduces sensory abnormalities such as hyperaesthesia and allodynia. Gabapentin and pregabalin are the most widely used anticonvulsants for treating CRPS. Common side effects of anticonvulsants include drowsiness, dizziness and weight gain. There's also a small increased risk of suicidal thoughts, which may occur as early as a week after starting treatment. Gabapentin had a mild effect on pain in CRPS I. It significantly reduced the sensory deficit in the affected limb. A subpopulation of CRPS patients may benefit from gabapentin. Medications that are commonly used and/or have some clinical data in CRPS are nonsteroidal anti-inflammatory drugs (NSAIDs) such as naproxen or ibuprofen; tramadol; antidepressants such as amitriptyline, doxepin, or trazodone; anticonvulsants (e.g., gabapentin), clonidine, clonazepam, baclofen, topical capsaicin cream, the 5% lidocaine patch Pregabalin has a chemical structure similar to gabapentin (Neurontin®), a medication originally developed to treat seizures that is now widely used to treat many varieties of neuropathic pain including CRPS/RSD. Both medications reduce pain by normalizing overactive pain pathways. Pregabalin is the first drug ever While there is evidence from case series suggesting its efficacy in CRPS, gabapentin is widely empirically used for various neuropathic pain syndromes. Pregabalin, a closely related drug with the same mode of action, can be used as well, although there are currently no data evaluating pregabalin specifically for CRPS . In cases of severe and Pregabalin has a chemical structure similar to gabapentin (Neurontin'), a medication originally developed to treat seizures that is now widely used to treat many varieties of neuropathie pain including CRPS/RSD (Compound Regional Pain Syndrome/Reflex Sympathy Dystrophy). Both medications reduce pain by nor-malizing overactive pain pathways. Gabapentin had a mild effect on pain in patients CRPS I. It significantly reduced the sensory deficit in the affected limb. A subpopulation of CRPS patients may benefit from gabapentin, but then for each individual patient the benefit has to be weighed against the frequently occurring side effects.
