Brain scan study of opioid effects in women with pain
This study uses brain imaging (MRI) to understand how opioid medications may affect the brain in women. People with chronic pain who take opioids (or do not) and healthy women without chronic pain may be invited to participate.
Durham, North CarolinaAges 18 years+ - NCT05905146Recruiting
Personalized opioid plan to shorten treatment time
This trial tests whether a personalized medication plan can help patients with short-term, non-cancer muscle or joint pain need strong opioid medicine for a shorter time. It’s aimed at improving how long treatment lasts while still managing pain.
LilleAges 18 years+ - NCT05885061Recruiting
Spinal cord stimulation study for adults with chronic pain
This study looks at how spinal cord stimulation affects chronic pain in adults who already have the device implanted. It may help researchers understand who benefits most and how stable pain and treatments need to be to measure results.
AarhusAges 18–99 - NCT05906511RecruitingEarly Phase 1
Study how THC levels change in older adults
This early study measures how a THC dose (by mouth or vaporized form) moves through the body and how it affects the body’s responses. It mainly looks at safety and how THC behaves in older adults, including people who have used cannabis before.
West Haven, ConnecticutAges 65 years+ - NCT05880212Recruiting
STOPS low back and leg pain approach for Bangladesh
This trial tests a specific physiotherapy program (“STOPS approach”) for people with long-lasting low back pain or leg pain from the back. It aims to see if the structured treatment, delivered by trained physiotherapists, improves pain and function over about 10 weeks.
Dhaka, UttaraAges 18–65 - NCT05865470RecruitingPhase 1
How age affects smoked and oral THC effects
This early-stage study compares how people in different age groups respond to THC taken by smoking versus by mouth. It aims to understand age-related differences in effects and safety, which could help guide safer use in the future.
Los Angeles, CaliforniaAges 18–65 - NCT05876390Enrolling by invitation
Regional anesthesia to reduce long-term breast surgery pain
This trial studies whether a pain-control technique called regional anesthesia during certain breast surgeries can lower chronic (long-lasting) pain after surgery. It may help improve comfort and quality of life for people at risk of ongoing pain after their breast operation.
Milan, LombardyAges 18 years+ - NCT05851768Recruiting
Easing thoracotomy pain with two different drugs
This trial compares two drugs added to a standard numbing medicine to see which works better for pain relief after chest surgery (thoracotomy). It may help find a way to reduce pain more effectively.
CairoAges 18–65 - NCT05862246Recruiting
Kids with foot or leg pain and normal leg function
This trial looks at children who have tightness, foot pain, and/or leg pain, as seen in a pediatric orthopedic clinic. The goal is to study this problem in children who otherwise seem healthy and do not have signs of a different underlying foot or medical condition.
TrondheimAges 4–16 - NCT05851976RecruitingPhase 4
Duloxetine for short-term non-radiating low back pain
This trial tests duloxetine (a medicine used for certain pain conditions and mood) for easing low back pain that started recently and doesn’t shoot down your leg. It may help reduce pain and improve daily function after an ER visit, but you must meet several safety and medication-use criteria.
The Bronx, New YorkAges 18–64 - NCT05818774Recruiting
Different types of neck nerve ablation for chronic pain relief
This trial compares two ways of using radiofrequency heat to treat a specific set of neck pain nerves (the “cervical medial branch nerves”). It may help people with long-lasting neck pain who did not improve with standard treatments and who respond to diagnostic nerve blocks.
Toronto, OntarioAges 18–85 - NCT05833048Recruiting
Pain-relief nerve block during cardiac surgery
This study tests whether a numbing “nerve block” placed in the rectus sheath area can reduce pain for people having certain heart surgeries with chest tubes. If you qualify, it may help your comfort during recovery, but it also depends on how suitable you are for local anesthesia.
New York, New YorkAges 18–85 - NCT05783245Recruiting
Cooling therapy to reduce pain after open carpal tunnel surgery
This trial studies whether cooling (cold therapy) can lessen pain after open carpal tunnel release surgery. If you’re having this surgery, your answers to questionnaires and your current pain-medication status will determine whether you can join.
Chicago, IllinoisAges 18 years+ - NCT05810428Enrolling by invitation
Using AI to predict outcomes and test pain treatment for trigeminal neuralgia
This study uses computer-based (AI) predictions to better understand what happens after a specific procedure for trigeminal neuralgia, a face pain condition. It also checks how well a “pain neuromodulation” approach works and what it feels like over time.
MilanAges 18 years+ - NCT05785884Recruiting
Diet program to help knee osteoarthritis pain
This trial studies whether different diet approaches can reduce knee pain in people with knee osteoarthritis who have certain eating patterns. It may help by changing diet-related factors that can affect inflammation and pain.
Birmingham, AlabamaAges 40–75 - NCT05788016Recruiting
