Filter by:Recent clinical investigations have suggested that the cause of abnormal pain in complex regional pain syndrome could be ischemia and inflammation, due to poor blood flow to deep tissues from microvascular pathology. This study aims to determine if a new technology called near infrared spectroscopy can measure this microvascular dysfunction. The study hypothesizes that significant differences can be measured in the microcirculation of patients with CRPS-I using near infrared spectroscopy and the vascular occlusion test.
The complex regional pain syndrom is a weighty disease that often results in a lifelong disability. Mostly this disease appears unilateral after comparatively mundane fractures or operations. In early stages CRPS shows inflammatory processes. These inflammatory components can be seen as edema and vasodilatation. These inflammatory processes lead us to the hypothesis that selective COX-2-inhibitors might help patients with CRPS.
The overall objective of this study is to assess patterns of fMRI cortical activation with spinal cord stimulation (SCS) in patients with neuropathic leg pain and therefore define cortical correlates, as well as to investigate cortical representations of pain and pain relief and the interactions therein, in the setting of neuropathic leg pain and SCS.
The purpose of this study is to see if the drug Pennsaid (Diclofenac) can help reduce pain felt by people with chronic nerve pain. The drug will be used 2-4 times each day for 2 weeks. The U.S. Food and Drug Administration (FDA) has approved Pennsaid to treat osteoarthritis (bone pain), but the FDA has not approved Pennsaid to treat neuropathic (nerve) pain. The research study will compare Pennsaid to placebo.
The purpose of this study is to investigated and evaluated the effectiveness of a new surgical technique for the treatment of severe chronic pain stages (Complex Regional Pain Syndrome Type II).
The use of prophylactic treatment with vitamin c may prevent complex regional pain syndrome (CRPS)
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.
This protocol matches child subjects with peer mentors of similar age who have learned to function successfully with a chronic pain disorder. The trained mentors will present information to the subjects in a supervised and monitored interaction via telephone and computer for 2 months and encourage participation in skill-building programs. Children will be tested for improvement in pain and functioning at 2 months and again at 4 months to see if improvements persist. The investigators hypothesize that children who received peer mentor support will show more improvement in pain and functioning at 2 and 4 months into treatment than those in a control group who do not receive mentor support.
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
This study theorized that a low dose of vaporized cannabis could alleviate nerve injury pain.
