Active clinical trials for "Chronic Pain"

This study is a multicenter, prospective, randomized, controlled research design. This study takes classic NSAIDs treatment as a control, and it will take patients' pain relief, functional improvement, sleep quality improvement, and adverse reactions as the main and secondary evaluation indicators to explore the safety and effectiveness of weak laser treatment of chronic musculoskeletal pain, determining the dominant disease in the treatment of Chronic pain.

This study examines the relationship between central nervous system (CNS) mechanisms of pain inhibition and the pain relief that occurs following a lumbar medial branch block (MBB).

Traumatic rib fractures (i.e., broken ribs caused by a physical injury) are common and very painful. They also often lead to serious complications, more time spent in hospital, and can even lead to death. Even after rib fractures have healed, they can lead to long-term pain and a lower quality of life. A technology called cryoneurolysis, which acts to freeze nerves causing pain using a small tool which can turn very cold, is a promising new way to manage rib fracture pain. This study is a test with a small number of people to see if it is feasible to use this technology for patients with rib fractures. If this is successful, we will recruit more people for a larger study to see if cryoneurolysis, along with standard pain control techniques, is better at stopping pain, compared to just the normal techniques alone. Participants in our study will be asked to rate their pain, and record pain medications that they take for 3 months after their pain procedure.

Over the last years a rising medical need for treatment of chronic pain was identified. Based on previous findings indicating the pain modulating effects of cannabinoids in chronic pain disorders, this clinical trial investigates the efficacy and tolerability of the THC-focused nano endocannabinoid system modulator AP707 in patients with pain disorders due to diabetic polyneuropathy. Patients receive AP707 or placebo over the course of 14 weeks as an add-on to the standard of care. Changes in pain intensity, quality of life and sleep and others measures are monitored through different scales to assess the efficacy of AP707 in patients with chronic pain due to diabetic polyneuropathy.

Based on previous findings indicating the pain modulating effects of cannabinoids in chronic pain disorders, this clinical trial investigates the long term efficacy and tolerability of the THC-focused nano endocannabinoid system modulator AP707 in patients with chronic back pain disorders. Patients receive AP707 or placebo over the course of 14 weeks as an add-on to the standard of care. Changes in pain intensity, quality of life and sleep and others measures are monitored through different scales to assess the efficacy of AP707 in patients with chronic back pain.

This qualitative nested sub-study will aim to explore how chronic pain (as defined as pain lasting for more than 3 months) impacts older adults' depression and treatment in a brief psychological therapy of behavioral activation (BA)

Patients with chronic pain syndrome (CPS) may develop central sensitization wich may lead to increased pain intensity and lower pain threshold sometimes to the extend of hyperalgesia and allodynia. Furthermore, patients with daily use of opioids may develop opioid tolerance, and to a lesser extent opioid induced hyperalgesia. These factors may lead to a higher pain intensity in the perioperative setting resulting in the observed increased opioid dosage needed to treat the acute pain. Furthermore opioid titration may be difficult with higher levels of pain and a higher risk of opioid related adverse effects incl. respiratory depression and sedation. The factors above advocate for utilizing opioid sparing analgesic techniques. In our department as in many others we use an multimodal opioid sparing approach for surgical procedures including epidural anesthesia (EA) as a standard part of the perioperative analgesia strategy after upper laparotomy, as a sufficient epidural anesthesia has shown to provide a stable and often better pain relief than systemic opioids in these patients. Clinically, there is a suspicion that patients with CPS on fixed opioid treatment have a higher frequency of need for epidural optimization, despite the lack of an anatomical reason for this. One potential explanation could be an altered nociception, requesting another EA strategy than in non-opioid patients. Purpose and hypothesis This study will explore the frequency of failed EA, defined as EA with insufficient analgesic effect to the extent were replacements of the epidural is needed within the first 5 postoperative days (PODs), testing the hypothesis that failed epidural occurs more frequent in patients with CPS on fixed opioid treatment than in non-opioid patients without CPS.

Spinal cord stimulation modulates the nervous system to effectively block pain signals originating from the back and legs. Spinal cord stimulation has been shown to improve chronic pain, improve quality of life, and reduce disability. Unfortunately, spinal cord stimulation has a high trial failure rate and a high long-term failure rate. This study consists of a prospective cohort of patients clinically scheduled to undergo spinal cord stimulation for the treatment of chronic back pain or radiculopathy. Participants will undergo a structured optimization evaluating existing types of stimulation (tonic, burst, and multistim). Each participant will try out all types of available stimulation but be blinded to the type. Over the course of four months, each participant will evaluate each type of stimulation by reporting daily pain scores. Thompson sampling will be used to identify which setting produces the biggest improvement in pain and recommend it for future use. Participants will follow up routinely to collect laboratory, behavioral, and survey responses to test for the feasibility of obtaining data explaining pain phenotype.

This study aims to assess how use of spinal cord stimulation for the treatment of chronic pain impacts brain structure and function. The investigators will use a non-invasive neuroimaging technique called resting state Near Infrared Spectroscopy and Electroencephalography (rs-fNIRS/EEG). The investigators will enroll Veterans who are currently receiving care at the Medical Center and who are either long term users of SCS for the treatment of their chronic pain or being evaluated for use of SCS to treat their pain.
