Active clinical trials for "Chronic Pain"

In this study the investigators aim to examine the effects of Transcranial Magnetic Stimulation (TMS) on hippocampal network connectivity and pain levels in individuals with pain due to knee osteoarthritis.

Propolis is a resinous product of honeybees. Propolis is said to be effective against resistant microorganisms inside the root canal compared to the gold standard medication known as calcium hydroxide. The clinical trial tests the effect of propolis versus calcium hydroxide on pain in patients with necrotic teeth.

This study is to determine the feasibility of an n-of-1, randomized, double blind, placebo controlled case series to examine effects of extended release opioids when used at intervals shorter than recommended by the manufacturer by people with chronic pain.

The purpose of this pilot study is to test the effects of testosterone replacement on pain, fatigue, mood, cognition and libido in hypogonadal men on long-term opioid therapy for chronic pain.

Adults and children undergoing medical care (inpatient or outpatient) often experience pain and anxiety either as a result of their medical condition or a side effect of medical procedures. The purpose of this study is to create a registry of patients using virtual reality (VR) mindfulness therapy through different aspects of their medical care to determine if VR mindfulness therapy is more effective than the standard of care (i.e., no technology based distraction) for treating or preventing anxiety and pain in adults and children suffering from chronic pain, GI conditions where pain is a common symptom, or undergoing any painful medical procedure (i.e. IV access, blood draws, endoscopy, surgery). The anticipated primary outcome will be reduction of pain and anxiety for both acute and chronic pain.

Over 100 million Americans report chronic pain. One of the most common causes of chronic pain is osteoarthritis (OA). OA is attributable to "wear and tear," but reasons for pain are complex. Inflammatory arthritis (IA) includes multiple severe diseases that affect 2-3% of persons and require treatment with immune-suppressive drugs to prevent joint destruction. Pain often persists despite effective treatment. Pain in arthritis results from multiple sources: inflammation, perception of pain in the joint, and interpretation of pain by the brain. Unfortunately, management of pain in arthritis remains a challenge. Low dose naltrexone is a widely used but unproven "alternative" approach to chronic pain. It is attractive for study because it is safe and is proposed to work on all three pathways that contribute to pain. A small but high-quality clinical trial is needed to determine whether to invest in definitive studies.

This is a prospective, descriptive, observational research study designed to observe and document the clinical practice by domain experts, and how the knowledge of new findings that are published in the medical literature affect clinical decision making. The study will evaluate risk factors and co-variants, including genetic variants that are associated with disease progression such as pain, inflammation, organ dysfunction, disability and quality of life.

The aim of this study to evaluate the effects of fibromyalgia syndrome accompanying women with chronic migraine on pain, quality of life, sleep, anxiety and depression, central sensitization and functionality.

The aim of this clinical study to evaluate the effect of temporomandibular joint dysfunction accompanying patients with chronic migraine on pain, quality of life, sleep and functionality.

It has been shown that prolonged continuous theta burst stimulation (pcTBS) , a relatively new repetitive transcranial magnetic simulation (rTMS) protocol, of the primary motor cortex (M1) or dorsolateral prefrontal cortex (DLPFC) decreases pain in healthy volunteers, in various experimental models. In addition, rTMS of M1 has also been shown to have analgesic effects in various chronic pain conditions, including neuropathic pain.The mechanisms underlying rTMS-induced analgesia remain unclear. Functional neuroimaging studies have shown that rTMS of M1 and DLPFC induces changes in the activity of cortical and subcortical structures involved in pain processing and modulation. Endogenous opioids and e N-methyl-D-aspartate (NMDA) receptor are known to play a major role in these processes. The investigator hypothesized that the endogenous opioids systems (EOS) and NMDA receptor might be involved in the analgesic action of pcTBS. In the first part,the investigator compares the analgesic effects of motor cortex (M1) or dorsolateral prefrontal cortex (DLPFC) stimulation before and after naloxone or placebo treatment, the intensity of pain induced by capsaicin were used to evaluate the analgesic effects of pcTBS. If naloxone does not reverse the analgesic effect of pcTBS,The volunteers will be invited to participant the second part of the study, which the investigator compares the analgesic effects of motor cortex (M1) or dorsolateral prefrontal cortex (DLPFC) stimulation before and after Ketamine treatment.
