Active clinical trials for "Chronic Pain"

As a result of COVID-19 and measures taken by the Canadian Government to reduce the transmission of the virus, in-person psychology services have been suspended. Psychology services are now being conducted via video conferencing. The purpose of the current project is to pilot-test a 6-week Self Compassion Treatment for Chronic Pain delivered virtually, in order to understand its utility in the current environment. The treatment is to be delivered through a secure professional ZOOM licence. Objective 1 of the project is to assess the feasibility and acceptability of attending the treatment group through virtual participation. Objective 2 is to assess the effectiveness of the group treatment in improving self-compassion, mental health, relationship with pain, and quality of life.

The aim of this clinical trial is to develop and test the effectiveness and cost-effectiveness of an internet-based self-management program based on pain education and exercise for people with chronic musculoskeletal pain.

Background: Radiotherapy is a common treatment for many malignancies. Radiation-related complications developing months or years after radiation treatment are known as late radiation tissue injury (LRTI) and are estimated to effect 5%-15% of all long-term survivors who have received radiation. Hyperbaric oxygen therapy (HBOT) is a well established treatment of LRTI. Most of the studies evaluating effect of HBOT on LRTI are focused on survival, resolution of tissue damage and improvement in LENT-SOMA scale. Very few studies have addressed effect of HBOT on pain in LTRI. Krahn and colleagues were the first to report the analgesic effect of HBOT in 3 cases of refractory pain in oncological patients with radiation soft tissue injury. Other studies showed significant improvement in pain intensity in patients with breast cancer and pelvic malignancies treated with HBOT for LTRI. In patients that had developed radiation- induced brachial plexopathy, HBOT elicited an increase in warm pain thresholds and a reduction in lymphoedema. A prospective case study of 16 patients with gynecological cancer found no changes with respect to pain and depression outcomes. A trial in patients with radiation induced proctopathy showed that 75% of patients with rectal pain had some improvement, although none experienced a complete resolution of pain symptoms. There are several mechanisms by which HBOT may elicit analgesic effects. There is a growing body of evidence that HBOT's analgesic effect related to nitric oxide metabolism and endogenous opioid secretion. Furthermore, the inhibition of tumor necrosis factor alph (TNF-α), the production of substance P, and the modulation of serotonergic pathways have all demonstrated a modification in the pain response following HBOT. In animal studies HBOT decreased allodynia and hyperalgesia in different models of neuropathic and inflammatory pain. The long lasting antinociceptive effect of HBOT was found to be dose-dependent in non-injured tissues. In human studies, HBOT decreased pain and edema and improved function in patients suffering from the complex regional pain syndrome, and improved pain scores and range of motion in patients with idiopathic femoral head necrosis. Women suffering from interstitial cystitis demonstrated a reduction in pelvic pain following weeks and months of HBOT treatment. In patients suffering from idiopathic trigeminal neuralgia HBOT produced a rapid reduction in symptoms and these effects were lasting for 6 months following treatment. HBOT was also found to be an effective treatment for cluster headaches and migraines and alleviated muscle and bone pains in patients with myofascial syndrome, fibromyalgia, and biphosphonate-related osteonecrosis of the jaw. Based on the evidence presented above and HBOT's known analgesic effect in many conditions, the investigators designed this study with the objective to evaluate if HBOT reduces pain, improves depression and impacts on patients quality of life in patients suffering from late radiation tissue injury. Study Design: Prospective observational study (n=300). Patients that have had radiation therapy for malignancy, developed late radiation injury and suffer from chronic pain.

This study will determine the efficacy of High Intensity Laser Therapy (HILT) for the treatment of elbow epicondylosis

For more than 25 years, Regional Anesthesia has challenged anesthesiologists to determine whether it offers real benefits in terms of patient outcome from major surgery, compared with general anesthesia. Although it is clear that regional analgesia in association with general anesthesia substantially reduces postoperative pain, the benefits in terms of overall perioperative outcome are controversial. The aim of this study is to evaluate the effect on short and long-term postoperative outcomes of adding regional analgesia to general anaesthesia in thoridetomic patients.

Sportsman's hernia causes chronic groin pain in physically active adults. Open hernia repair without mesh or laparoscopic technique with mesh have been advocated in the treatment of sportsman's hernia. The aim of this randomized study is to compare the effectiveness of open technique to laparoscopic technique for the treatment of Sportsman´s hernia. The hypothesis is that laparoscopic technique is less painfull than open surgery for repair of sportsman's hernia.

The wars in Iraq and Afghanistan are creating a new generation of Veterans, including an increasing number of women Veterans, who present with comorbid PTSD and chronic pain conditions from recent deployment-related physical injuries and exposure to psychological trauma. Health behavior change has become increasingly important in treating these conditions and proactively preventing long-term negative health sequelae, in order to benefit these Veterans directly and reduce the growing challenges to our healthcare system. The proposed CDA-2 program of research will use an innovative translational research approach to study whether a chronic progressive -based exercise program will reduce chronic pain in patients with PTSD and to elucidate and modify potential PTSD-related deficiencies in neurobiological and psychological responses to exercise to optimize the physical and psychological benefits of exercise for these individuals.

Chronic pancreatitis is a progressive inflammatory disease resulting in slow destruction of the pancreas. This chronic inflammation can lead to chronic abdominal pain which can last for many years. Unfortunately, medical management often is of only limited benefit in treating the pain of chronic pancreatitis. Management of patients with intractable pain is difficult, often resulting in narcotic addiction. Early results in a small group of patients suggest that percutaneous radiofrequent lesioning of splanchnic nerves has good potential for pain control in a subset of patients with chronic pancreatitis. Given the simplicity of the procedure, it clearly warrants reappraisal to identify its current role in pancreatic pain management.

The purpose of this study is to develop and pilot test clinical guidelines for the use of buprenorphine for the treatment chronic pain among patients with substance abuse histories. Buprenorphine, an opioid medication, holds promise as a treatment of chronic pain because, compared to most other opioid analgesics, it has a high safety profile, a low level of physical dependence, and mild withdrawal symptoms on cessation. Moreover there are promising reports from Europe of its use as a skin patch to treat chronic pain as well as clinical reports in the U.S. that it may be effective when used sublingually (placed under the tongue). This study will test the sublingual formulation.

The investigators are evaluating refugee torture survivors who are receiving services at the Weill Cornell Center for Human Rights. There are two research questions in this study: if the current standard of care results in the under or missed diagnosis of pain and pain syndromes, and if a validated pain screening tool can supplement the current standard protocol used in the assessments of survivors of torture.
