Chronic pain syndrome

This study investigates whether a spinal cord stimulator (SCS) alters the sympathetic nervous system — the body's fight-or-flight response — in people with Complex Regional Pain Syndrome (CRPS). Ten adults with CRPS will have their nerve activity, heart rate, and blood pressure m…

This early study is testing whether metformin, a common diabetes medicine, can reduce pain and help heal chronic Achilles tendon problems. Forty people with long-term tendon pain will take either metformin or a placebo pill for 16 weeks, along with a home exercise program. Resear…

This study tested a program called PRIME for older women with chronic pain and depression who also have physical disabilities. Nine women took part in nurse-led goal-setting visits and group therapy sessions focused on acceptance and commitment. The goal was to see if this combin…

This study looked at whether adding guanfacine (a blood pressure medicine) to morphine could reduce pain sensitivity and tolerance in people with chronic neck or back pain. The study planned to enroll 137 adults who had not taken opioids recently. However, the study was terminate…

This study looked at whether adding guanfacine to opioid painkillers could reverse the extra pain sensitivity that long-term opioid use can cause. It involved 8 adults with chronic neck or back pain who were already taking opioids. The study was terminated early, so results are l…

This study tested whether osteopathic care (hands-on manipulation) can help reduce pain in people with fibromyalgia. 32 participants received osteopathic treatments over 8 months, with a follow-up 3 months later. The goal was to see if this approach could improve pain and quality…

This study tested whether adding pregabalin (Lyrica) to standard treatment could reduce pain and improve function in people with complex regional pain syndrome (CRPS) of the upper limb. Only 14 adults were enrolled before the trial was stopped early. The goal was to see if the dr…

This study tested whether a six-week course of yoga, mindfulness, and breathing exercises could help people with chronic pain feel better and manage stress. Only 5 patients took part before the trial was stopped early. Because it was so small, we cannot say whether these techniqu…

This early-stage trial tested the safety and how the body processes Kindolor Tosylate, a potential new drug for chronic pain. It involved 16 healthy adults who received either the drug or a placebo. The study was terminated, so full results are not available.

This study looked at whether buprenorphine can effectively treat chronic pain in people who are dependent on opioid painkillers, while also reducing withdrawal symptoms and improving quality of life. It involved 4 adults with opioid dependence and chronic pain. The approach was t…

This study tested a new method for starting buprenorphine (a medication for opioid use disorder) in hospitalized adults who also have chronic pain. Instead of requiring patients to stop all other opioids and go through withdrawal first, the new method starts with very low doses o…

This study looked at whether a brief, noninvasive brain stimulation technique called tDCS could immediately reduce pain and improve function in people with fibromyalgia or chronic fatigue syndrome. About 20 participants received one session, and researchers measured changes in pa…

This study aimed to see if a personalized physical activity program, with one face-to-face session followed by phone coaching, could improve quality of life for people with fibromyalgia compared to standard group exercise classes. The trial was terminated after enrolling only one…

This study looked at a new type of spinal cord stimulation called burst stimulation (Burst-SCS) to see how it reduces chronic pain. It included 12 people with long-term pain, mostly from failed back surgery. The trial was terminated early, so the findings are limited and not conc…

This study looks at whether imagining positive future events (Episodic Future Thinking) and using low-intensity focused ultrasound on the brain can help people with both chronic pain and alcohol use disorder. Ten adults will try these interventions and report changes in pain, cra…

This study looks at how oxytocin, a natural hormone, affects the part of your nervous system that controls rest and digestion. Researchers will give a single injection of oxytocin or a placebo to 38 people (some with knee arthritis, some healthy) and measure tiny changes in pupil…

This study looked at whether people with chronic pain who tend to catastrophize (imagine the worst) about their pain experience stronger cravings for prescription opioids. Researchers measured cravings, stress hormones, and mood in 93 adults who had been taking opioids for at lea…

This study looked at a type of spinal cord stimulation (SCS) that doesn't cause tingling, called paresthesia-free SCS, in 10 adults with chronic pain. Researchers wanted to see how well it works and how it affects pain perception. The study was terminated early, so the findings a…

This study looked at using a mobile app to collect feedback from 91 adults with chronic pain who were already receiving spinal cord stimulation (SCS) therapy. The goal was to see how well the app worked for gathering information on their pain and overall improvement. The study di…

This study aimed to find out how many people experience short-term and long-term pain after a specific type of heart surgery called one-stage hybrid arrhythmia ablation. Researchers surveyed patients who had the procedure at UZ Brussels to see what factors, like medications or ge…
