Filter by:The present study investigates by means of the rubber hand illusion body image stability and sense of body ownership in patients with CRPS of the upper limb compared to patients with unilateral pain of origin other than CRPS and age and sex-matched healthy subjects.
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 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.
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.
This study theorized that a low dose of vaporized cannabis could alleviate nerve injury pain.
The purpose of this study is to evaluate the efficacy and safety of fentanyl in opioid-naive participants with post-herpetic neuralgia, complex regional pain syndrome or post-operative pain syndrome who cannot obtain a sufficient analgesic effect by the treatment of non-opioid analgesics (drug used to control pain).
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.
The current Dutch CBO guideline treatment of Complex Regional Pain Syndrome Type I (CRPS-1) is very disappointing with chronification, disability and subsequent high medical costs and personal suffering. A possible better treatment is intensive function-oriented physical therapy or Pain Exposure in Physical Therapy (PEPT). However, there are no adequate studies performed that demonstrate the efficacy of PEPT and therefore PEPT is lacking in the Dutch CBO CRPS-1 guidelines. Despite a lacking scientific argumentation, the PEPT approach or Macedonian therapy, is now being adopted on a large scale among physical therapists in The Netherlands. There are two level C retrospective cohort studies demonstrating a promising and clinical relevant beneficial effect on pain and function after PEPT. In response to the growing demand for scientific argumentation among doctors and physical therapists with respect to the efficacy of PEPT, we conducted a pilot study at the UMC St Radboud Nijmegen. The results of this pilot study were very promising and therefore, we decided to design a large RCT to investigate the treatment effects and costs in CRPS patients treated with PEPT compared to CRPS patients treated with usual therapy according to the Dutch CBO guidelines.
Lumbar sympathetic blocks are part of the standard of care for treating patients with sympathetically-maintained pain (e.g. in complex regional pain syndrome or reflex sympathetic dystrophy- RSD). In these patients lower extremity pain can be reduced or abolished temporarily by blocking sympathetic nerves by doing a lumbar sympathetic block. Patients who respond only transiently to sympathetic blocks often choose between potentially dangerous lumbar sympathetic block with neurolytic agents, surgical sympathectomy, continued severe refractory debilitating pain or other risky invasive surgical procedures such as spinal cord electrical stimulation.. It is hypothesized that Botulinum Toxin Type A (BTA) injected in a lumbar sympathetic block can provide extended sympathetic blockade and thus pain relief. This pilot study aims to see if BTA can be used safely in lower extremity sympathetic blocks, and might be useful in providing prolonged pain relief.
Background: Research on the treatment of CRPS-I, as described in the Dutch evidence based treatment guidelines (Richtlijn Complex Regional Pain Syndrome type I, 2006), mainly showed improvement at the level of pain and coping with pain. Only little improvement in functional restoration was found. Research in other pain populations such al neck- and back-pain patients has shown that pain related fear contributes to the development of functional disability. GEXP in vivo which aims on systematically reducing fear of movement, shows promising results in CRPS-I patients (de Jong et al., 2005). Objective: The objective of the proposed project is to compare the effectivity of GEXP in vivo with that of standardized physiotherapy in CRPS-I patients with pain related fear. Design: The study concerns a single blinded, single center, randomized clinical trial. The treatment will be preceded by two pre-measures. After treatment there will be one post-measurement and 3, 6 and 12 month follow-up measurements. Population: The study population will consist of chronic CRPS-I patients between 18 and 65, with pain related fear (PHODA-LE-score ≥ 35 and PHODA-UE-score ≥ 32). Intervention: The two interventions that will be compared are GEXP in vivo (de Jong et al., 2005) and standardized physiotherapy according to the protocol of Oerlemans, Oostendorp, de Boo en Goris (1999). The GEXP in vivo comprises 17 sessions of one hour, the physiotherapy treatment of 34 sessions of 30 minutes. Both treatments will be given over a period of 17 weeks.
