Active clinical trials for "Chronic Pain"

This is a clinical trial that intend to determine if transcranial direct current stimulation (tDCS) is effective in the treatment of postoperative pain and in the anxiety level in the preoperative period of hallux valgus surgical treatment

The use of cannabis for severe medical conditions is being legalized in different states, increasing the mandate to make cannabis legal for medically ill patients. However, there is a lack of placebo-controlled studies investigating the efficacy of cannabis. Dronabinol (synthetic, oral Δ-9-THC) is FDA approved for the appetite stimulation in AIDS-related anorexia and nausea/vomiting in chemotherapy patients. Nabilone, a synthetic analogue of THC, is approved for nausea/vomiting in chemotherapy patients. These medications have been found to be effective for these disorders, but there remains an interest in studying cannabis, partly due to the numerous cannabinoids contained within the cannabis plant. Among these is cannabidiol, which does not produce subjective effects, but has been shown to have potent anti-inflammatory effects. In addition, there is data indicating that cannabidiol may be effective for neuropathic pain and nausea/vomiting. The goal is to investigate the effects of high CBD/low THC cannabis on symptoms such as pain, nausea/vomiting, and quality of life in seriously ill participants. While there is data beginning to emerge that cannabis may have a beneficial effect on these symptoms, there are few placebo controlled, double-blind studies. Additionally, the administration of cannabis to medically ill patients may be limited by its subjective effects, such as anxiety, intoxication, or paranoia. Most cannabis available today has high levels of Δ-9-THC (about 15%). By using cannabis that is high in CBD, but low in - Δ-9-THC, it is hypothesized that some of these effects can be avoid, while maximizing the therapeutic effects, if any.

The purpose of this study is to evaluate the effectiveness, tolerability, and safety of oxymorphone immediate release (IR) oral liquid as an analgesic in pediatric subjects having severe to moderate chronic pain.

The study seeks to investigate a safe and inexpensive strategy to reduce persistent post-surgical pain that can affect up to 60% of patients undergoing surgical procedures. Hypotheses: Perioperative systemic lidocaine reduces the persistence of chronic pain in patients undergoing surgical procedures.

A study for patients who have chronic postoperative pain who had knee replacement surgery. If qualified, a 14 day trial and an implantation of spinal cord stimulator for control of pain will be administered. This study will evaluate effectiveness of pain control. Subjects will be followed for one year post implantation.

Chronic pain after spinal cord injury in or below the level of injury is a common problem and can be severe. The purpose of our study is to investigate the effect of pleasant guided imagery on spinal cord injured patients with chronic pain in or below the level of injury.

Chronic musculoskeletal disorders are global burden for economy. Fear-avoidance (FA) seems be a predictor for the transition from subacute to chronic pain. One of the most famous scales to access FA is the Tampa scale of kinesiophobia, but several responders think some items are not clear, too narrow or too general. A new scale, the Fear-Avoidance Components Scale (FACS) was developed by Neblett et al. in 2015 to assess FA. It is a comprehensive set of concepts that more effectively addresses all the essential issues of the FA concept than the current scales. The new scale comprehensively assesses all cognitive, emotional, and behavioral components related to the updated FA model by combining items from well-known scales in the context of the FA model with items on perceived injury-related victimization and blame. A French version of the FACS is currently lacking. The aim of this study is to provide a translation and validation of a French version of FACS in patients with musculoskeletal disorders.

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.

This study evaluates the effect of fascia iliaca compartment block (FICB) in the management of acute post -surgical pain in hip fracture patients and in the appearance of chronic post -surgical hip pain, by means of von Korff Graded Chronic Pain Scale -modified for hip pain in Greek. Half of the patients will not receive fascia iliaca compartment block.

Randomized, double-blinded, three arm study in adult patients undergoing first time coronary artery bypass grafting (CABG) surgery with median sternotomy. The investigators will examine the effects of three fentanyl dosing schemes (high-dose bolus, low-dose bolus, continuous dose) on the area of hyperalgesia and allodynia at 24 and 48h as well as on persisting pain at 3, 6, and 12 months. Additionally, the investigators will measure fentanyl concentrations throughout anesthesia.
