Filter by:This pilot study will test a new therapy, somatosensory rehabilitation, for the painful sensitivity experienced by persons with nerve injuries and/or complex regional pain syndrome (CRPS). Several methods for measuring pain and sensitivity that emphasize the person's evaluation of their own symptoms and the impact of these symptoms on their daily activities will also be tested to make sure they are consistent and accurate. Previous research has suggested one of the assessments may also be used to assist in the identification of CRPS: this simple test will be evaluated to see if it can accurately identify persons with this disorder (for which there is currently no diagnostic test). Together, this will improve treatment of CRPS through early, accurate diagnosis and the ability to measure important changes in this painful condition, and set up future studies for this new rehabilitation treatment method.
This study aims to compare the alternative current and the direct current signal changes of photoplethysmography between both feet during one side lumbar sympathetic block. The hypothesis is that signal changes occur earlier than other indices to decide whether it is successful following lumbar sympathetic block on only one-side.
Distal radius fractures (DRF) are the most common type of fracture in the human body, and a large proportion of DRFs result in complications. Previously proposed preventive strategies have questionable efficacy and may impose additional risks on the patient. Because many complications secondary to distal radius fractures are associated with excessive swelling, a prophylactic means for edema reduction could dramatically reduce morbidity among this population. A compression glove is a non-invasive, non-pharmacological way to reduce edema. Previous studies have confirmed its utility in edema reduction after hand trauma and among patients with chronic inflammatory conditions, but none have sufficiently investigated the application to patients with distal radius fractures, a population in which this intervention could have a large impact. The investigators propose a randomized controlled trial to evaluate use of a compression glove during recovery among patients who have sustained an unstable distal radius fracture. The investigators hypothesize that patients who wear a compression glove after a distal radius fracture: - Will experience less edema - Will demonstrate greater functionality - Will recover more quickly - Will have lower incidence rates of carpal tunnel syndrome - Will have lower incidence rates of complex regional pain syndrome
Patients with postherpetic neuralgia (PHN), diabetic neuropathy (DN), complex regional pain syndrome (CRPS), carpal tunnel syndrome, HIV neuropathy, idiopathic sensory neuropathy, or other peripheral neuropathy participated in a Phase IV clinical trial to assess the comparative efficacy and safety of Lidoderm monotherapy versus gabapentin monotherapy in treating a diverse group of peripheral neuropathic pain patients.
To demonstrate that spinal cord stimulator has an effect on sympathetic function (the one that give us the fight and flight response). Therefore, if the spinal cord stimulator has an effect on sympathetic function, the responses from CRPS patients to different stimuli will differ significantly pre and post SCS implant. If CRPS patients exhibit autonomic, CRPS patients could be stratified according to their sympathetic function pre-implant. It is expected that patients with a moderate/mild form of autonomic dysfunction will have better outcomes with the SCS.
Complex Regional Pain Syndrome is a debilitating and extremely difficult to treat condition. There is a large body of evidence demonstrating the therapeutic value of N-methyl-D-aspartate (NMDA)-receptor antagonists in CRPS. The NMDA antagonist ketamine has been shown to be effective in the treatment of CRPS, resulting in complete remission of the disease in some patients. The purpose of this study is to evaluate intravenous outpatient infusion of sub-anesthetic doses of ketamine for the treatment of CRPS. A thorough evaluation of this procedure, providing information into the degree of relief and which of the constellation of RSD symptoms are best alleviated by this procedure would result in the optimization of this therapy for the treatment of CRPS.
The objective is to determine if motor cortex stimulation works for the following conditions: 1. Deafferentation facial pain, 2. Upper extremity complex regional pain syndrome (CRPS) and 3. Brachial plexus avulsion or phantom limb pain. Each of these groups of 6 patients (total of 18) will be studied independently and all patients will be implanted with a motor cortex stimulation system. They will be randomised to either a regular or low stimulation setting in the two arms of the study. Each arm will last 3 months.
The primary objective of this study is to compare the efficacy of SCS using the Precision implantable neurostimulation device and conventional medical treatment (nerve blocks + physical therapy) in subjects with recently-diagnosed Complex Regional Pain Syndrome (CRPS) after some more conservative treatments have failed. There are significant numbers of patients with CRPS in whom conventional treatment is ineffective and SCS is used only as a last resort. If SCS is effective earlier in the treatment continuum, it would provide a much needed treatment alternative and increase awareness of the utility of SCS for this indication. It is also possible that early intervention with SCS may limit disease progression.
