Active clinical trials for "Complex Regional Pain Syndromes"

The efficacy of the current standard non-pharmacological treatments for complex regional pain syndrome (CRPS), a painful syndrome mostly occurring after musculoskeletal trauma, is suboptimal. It thus appears essential to examine new non-pharmacological therapeutic imagery (GMI) - a non-pharmacological approach with the highest level of evidence (level II). As suggested by the most recent clinical guideline 2, a potential solution would be to add an electrotherapeutic procedure - transcranial direct current stimulation (tDCS) - that may prove effective in modulating cortical excitability and reducing the effect of cortical reorganization on pain. Given the positive results previously obtained in patients with neuropathic pain, it is hypothesized that tDCS will prove to be an innovative add-on treatment method for CRPS patients, and help reduce pain and disability.

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

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).

The efficacy of fentanyl TTS for the treatment of neuropathic pain remains to be established, although opioids in general are clearly effective for neuropathic pain and fentanyl TTS has been shown to be effective for treating other types of pain. We propose to measure functional outcomes, pain relief and side effects of fentanyl TTS for the treatment of neuropathic pain. Measures will be made at baseline and after titrating the drug to an effective level.

This is a multicenter, open-label study in adult subjects with Type 1 Complex Regional Pain Syndrome. Subjects diagnosed with unilateral Type 1 CRPS will be enrolled sequentially to receive CC-5013 10 mg/day orally. For each subject the study consists of two phases: Pre-treatment phase(1 wk) and treatment phase (12 wks)

Pain, when it becomes chronic, can be a threat to patients and it is very common to observe a fear of pain and a fear of movement (kinesiophobia). Avoidance of movement due to fear of pain can lead to a deterioration of body image. Non-medicinal therapies are essential to correct this fear and movement avoidance behavior, to decrease "catastrophic" judgments and thus anxiety. The use of art-therapy in the accompaniment of patients with pain has shown, in particular, decreases in the intensity of pain, the level of anxiety, an improvement in stress, mood and overall psychological state. However, according to the current literature, it appears that 1) this technique is rarely used in children or adolescents, for whom non-medicinal therapies are fundamental, and 2) in the case of chronic pain, the form of art used is very rarely related to the body (most often painting, drawing, music...). In this project, investigators propose to set up and test the potential benefit of art-therapy sessions related to the body, namely dance-therapy, in adolescents and young adults suffering from chronic pain.

The purpose of this study is to investigate the effect of soticlestat (TAK-935) on calculated 24-hour average pain intensity by the numeric pain scale (NPS).

This study theorized that a low dose of vaporized cannabis could alleviate nerve injury pain.

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: Deafferentation facial pain, Upper extremity complex regional pain syndrome (CRPS) and 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.
