Filter by:This is a sham controlled, randomized, double-blind, navigated repetitive Transcranial Magnetic Stimulation (nrTMS) study for the treatment of complex regional pain syndrome (CRPS types 1 and 2). The investigators study factors that may contribute to development, maintenance, or treatment responses with clinical, sleep, and psychiatric questionnaires and clinical examinations, quantitative sensory testing and neurophysiologic recordings, genetics, and MRI techniques.
Chronic pain affects 1 in 4 US adults, and many cases are resistant to almost any treatment. Deep brain stimulation (DBS) holds promise as a new option for patients suffering from treatment-resistant chronic pain, but traditional approaches target only brain regions involved in one aspect of the pain experience and provide continuous 24/7 brain stimulation which may lose effect over time. By developing new technology that targets multiple, complimentary brain regions in an adaptive fashion, the investigators will test a new therapy for chronic pain that has potential for better, more enduring analgesia.
Alpha 2 macroglobulin (A2M) is a plasma protein that acts as a molecular trap for inflammatory factors such as tumor necrosis factor (TNF). After plasma is enriched for A2M, it may be injected for treating chronic inflammation. Plasma enriched for A2M may be considered as a possible injectable agent to counteract inflammation that may occur with a cervicobrachial pain syndrome. This study reports on an experiencing using A2M to treat cervicobrachial syndrome which was predominant for either musculotendinous or neuralgic features.
Motor neglect describes a loss of function without a loss of strength, reflexes or sensation. Motor neglect has been described in patients with traumatic brain injury, stroke and chronic pain conditions, e.g. complex regional pain syndrome. These conditions affect hundreds of thousands of patients in the UK each year and motor neglect is a significant obstacle in their rehabilitation towards a good outcome. By focussing on improving motor neglect, outcomes including function and quality of life for these groups of patients may significantly improve. Motor neglect is potentially reversible. Rehabilitation using repetition, feedback and motivation are beneficial for optimal outcome. Current protocols use face-to-face physical therapies which can not optimise intensity due to a lack of resources. Furthermore, engagement with exercise is recognised to be poor, in part, due to a lack of attention. Innovative technologies may well improve engagement. Furthermore, telemedicine, or remote delivery of healthcare, offer opportunities in resource management, which can be delivered through the use of such innovative technologies. Virtual reality systems have been designed and utilised in rehabilitation in various conditions, e.g post-stroke, cerebral palsy and Parkinson's disease. Studies demonstrate improved function in both upper and lower limbs. Potentially more effective treatments for motor neglect utilising such technology are therefore available but need more formal evaluation. This protocol describes a Phase II randomised controlled trial for both in-patients and out-patients requiring rehabilitation with motor neglect from neurological causes (stroke, traumatic brain injury) and chronic pain conditions (Complex Regional Pain Syndromes, chronic low back pain and referred leg pain (sciatica)). The intervention will be a novel interactive virtual reality system using established technology and tailored software used in conjunction with a treadmill. The control group will be the same screen showing random static images whilst on the treadmill. Rehabilitation for each group will be offered in 3-4 sessions per week for 2 weeks. Each session will last about 30 minutes supervised by a physiotherapist. Follow-up will be by questionnaire at weeks 2, 6 and 12 and by face-to-face consultation at weeks 2 and 12.
Background. Sympathetically maintained pain (SMP) can be effectively relieved by light irradiation to the area near stellate ganglion (SGI), which is applied as an alternative to sympathetic blockade. The clinical efficiency of SGI on heart rate variability (HRV) and its association with pain outcome need to be further identified. Objectives. This study is aimed to identify the effects of SGI on pain, HRV indices, quality of life, and function outcomes. Design. A prospective, double blind, randomized designed study Setting. An outpatient pain medicine clinic Subjects and Methods. A total of 44 patients will be enrolled and randomized to their allocations: the experimental group (EG, n=22) and control group (CG, n=22). All patients in EG will receive 12 sessions (twice a week) of standard SGI, while those in CG go through the same protocol except a shame irradiation is applied. Pain, HRV variables, quality of life, and function outcoms are measured before and after SGI in each session. All measures at the first-half and second-half courses are analyzed.
The purpose of this prospective, multicenter, single arm post-approval study is to demonstrate continued safety of the Axium and Proclaim Neurostimulator System for dorsal root ganglion (DRG) stimulation. The primary endpoint is the 12-month serious adverse event rate for permanent implants.
This is a randomized, double-blind, placebo-controlled, 24-week study to evaluate the efficacy and safety of AXS-02 in patients with CRPS-I.
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.
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 examine the short and long-term benefits of implementing early regional anesthesia techniques for pain control after a major traumatic injury to one or more extremities during combat in the Iraqi/Afghanistan war, including the effects on acute and chronic pain, quality of life, and mental health.
