Active clinical trials for "Chronic Pain"

Lumbosacral radicular pain is present in around 40% of cases of low back pain. It is usually caused by irritation and inflammation of the nerve root, and patients typically experience pain radiating from the back to the lower limb in the distribution of the affected spinal nerves. Epidural steroid injection is the most commonly used pain-relieving procedure in the world. However, the analgesic efficacy of epidural steroid injection appears to be modest and duration limited. Platelet rich plasma (PRP) is an emerging treatment option for chronic pain. It is currently used for treating musculoskeletal pain conditions such as osteoarthritis and tendinopathies. While epidural steroids reduce pain by reducing inflammation, PRP promotes the healing of nerve injury and reduces neuropathic pain. However, the effect of transforaminal epidural PRP versus epidural steroid specifically for lumbosacral radicular pain is unclear. In this study, a double blind, randomized controlled trial will be performed to compare the effect of transforaminal epidural PRP versus epidural steroid for pain relief in patients with lumbosacral radicular pain.

The overall aim of this cluster ranomized controlled trial is to investigate whether an intervention for collaboration between patient with CMD or chronic pain and employer (the Demand and Ability Protocol) can contribute to reduced sick leave and to increased health, work ability and trust in the managers. The intervention is delivered by rehabiliation coordinators at primary health care centres.

With this randomized controlled trial, we have three aims. First of all, to investigate underlying mechanisms that might contribute to the success of a physical activity focused self-management program in paediatric chronic pain. Second of all, to determine the minimum intervention needed for improving physical activity amongst adolescents who live with chronic pain. For this we are comparing an in-person and a video-based motivational interviewing training combined with self-management techniques. Third of all, to investigate the mediating effect of autonomy in adolescents with chronic pain.

The primary aim of this pilot trial is to enhance the efficacy of the Mindfulness-Oriented Recovery Enhancement (MORE) intervention by adding neurofeedback (NF) of the Orbitofrontal Cortex (OFC) as an adjunct to the savoring component of MORE. We hypothesize that the use of NF to train OFC responses during savoring will amplify patients' ability to savor and thereby increase brain responsivity to natural rewards; such enhanced reward responding will in turn be associated with improvements in clinical outcomes (e.g., pain, analgesic use).

This study will compare two available, evidence-based, digital pain treatment programs that patients can use at home. The goal is to see if one approach is better than the other, and whether certain patients respond to one more than the other. Study participants will be randomized to receive one of two treatment programs: Skills-Based VR or painTRAINER. Study devices will be delivered to the participant's home with instructions for use via FedEx; participants will receive remote technical support. They will be followed for 60 days and complete Patient Reported Outcome (PRO) questionnaires to assess functional status, pain levels, and use of pain medications (including opioids). Participants will also be asked to provide consent/authorization to access medical records from their treating facility.

Severe chronic pain is defined as pain persisting for three months or more that significantly impacts daily functioning. It is highly prevalent, occurring in 100,000 to 160,000 youth. If left unmanaged it can lead to persistent pain and mental health problems in adulthood, posing enormous costs to society ($7.2 billion CAD/year). In 2014, health professionals at the Alberta Children's Hospital (ACH) established a pediatric Intensive Pain Rehabilitation Program (IPRP) to target youth with severe chronic pain and consequent functional disability who do not respond to outpatient pain therapies. The IPRP at the ACH is a three-week intensive day-treatment intervention provided by an interdisciplinary team, which helps youth resume engagement in normal daily functioning. Following IPRP, youth reported less anxiety, less depressive symptoms, and greater function, although their self-reported pain remained unchanged. In August 2016, the investigators began to explore brain areas related to severe chronic pain in youth. The investigators scanned a subset of youth at the start (baseline) and end (discharge) of IPRP (23 youth with 2 brain scans). From baseline to discharge, the investigators saw decreases in activity in the dorsolateral prefrontal cortex (DLPFC). Decrease in DLPFC activity was related to better mental health outcomes. The DLPFC is a well-known target for non-invasive brain stimulation. Repeated brain stimulation has been used to treat adults, but not youth with chronic pain. For the first time, the investigators will use image-guided brain stimulation (37 minutes/day, 5 days/week) to enhance the brain changes observed with IPRP. The investigators will examine whether three weeks of brain stimulation helps to reduce pain symptoms in youth. The investigators will also compare pain, brain, and mental health outcomes to our historical program data. By adding brain stimulation to our pain intervention, the investigators have the chance to target an area of the brain investigators know to be altered by chronic pain to improve outcomes.

Cancer in general, and breast cancer in specific, is a significant health problem in the USA and the rest of the world. With the improvement of new surgical approaches and chemotherapies to manage breast cancer, the number of patients with breast cancer are now living longer. This great achievement created an unexpected problem. For some breast cancer patients, with bone metastases, the pain is worse than the cancer. The golden standard to manage pain is opioids. Patients with cancer-induced bone pain are now taking increasing doses of opioids to control their pain. Sadly, opioids come with significant side effects that limit the amount of opioids that can be safely given. Many attempts have been tried to create better regiments for pain control to lower the need for opioids. There has not been significant success in that area. A better approach would be to add a non-opioid agent that has dual mechanisms of action. This may create synergism to better control pain while lowering the doses of opioids needed and lowering side effects. Sulfasalazine poses such quality it is a safe anti-inflammatory drug with established safety profile. It has been in use for over 50 years for the treatment of inflammatory conditions such as arthritis. In addition to its anti-inflammatory characteristics, sulfasalazine has the capacity to decrease the survival of cancer cells, also to lower the number of inflammatory mediators released by cancer cells. In short, sulfasalazine inhibit the influx of cysteine into cancer cells and the efflux of glutamate. Cysteine is needed for cell survival against oxidative stress, while glutamate activate pain receptors. Therefore, sulfasalazine will act as anti-inflammatory, an agent to accelerate cancer cells death and decreasing the released glutamate which activate pain receptors. This one agent with 3 mechanisms of actions may lower the amount of opioid needed for these patients while maintaining or improving their pain. Lowering of opioid dosing may also improve the side effects associated with opioid use. The purpose of this trial is to co-administer sulfasalazine with opioids to cancer patients and characterize their pain and the opioid use. Our hypothesis is that adding sulfasalazine to the pain medication, will lower the amount of opioids used and lower the side effects. This may improve the quality of life for patients and decrease the risks of using high amount of opioids for the patients, their families, and society in general.

In this study, the investigators will examine the analgesic effects of acupuncture imagery treatment in patients with chronic low back pain. The intervention used in this study is "video-guided acupuncture imagery treatment" (VGAIT) treatment. The control used in this study is sham (fake) VGAIT. Participants in each group will participate in 8 study sessions (including 6 treatment sessions) over the course of 6 weeks. The primary outcome measure for this study is change in low back pain severity score after each treatment session.

Vulvodynia (i.e. chronic vulvar pain without identifiable cause) is a heterogeneous clinical entity with a complex multifactorial causation. It is long lasting and difficult to treat, and the general consensus of current guidelines states that patients with vulvodynia benefit from a compound multidisciplinary intervention targeting mucosal hypersensitivity, pelvic muscle floor dysfunction and general pain management. However, there is little empiric evidence to support this recommendation. This will be a randomized controlled trial comparing multidisciplinary treatment with standard care for women with vulvodynia.

This is a study to evaluate the efficacy and safety of lidocaine in the management of chronic pain in children. All participants will receive lidocaine infusion and severity of pain and degree of chronic-pain related disability will be assessed before and up to 4 weeks after infusion. Adverse events will be recorded.
