Early mental exercise after shoulder tendon repair
This study tests if a gentle, early mental exercise program helps improve shoulder recovery after a specific type of rotator cuff repair. It might be a good fit if you had surgery on two front shoulder tendons and are otherwise healthy.

Nerve block comparison for buttock nerve pain
This study compares two ways of giving a numbing injection (nerve block) to treat a condition where a nerve in the low back gets pinched, causing long-term buttock or low back pain. It aims to see which method works better.
IstanbulAges 18–75 - NCT03231241Recruiting
Study of worsening headaches using scans and blood testing
This study looks at why headaches can become long-lasting (“chronified”) by combining answers from online questionnaires, brain imaging, and blood protein tests. Your participation may help researchers find biological clues that could improve how headache problems are understood and treated.
Stanford, CaliforniaAges 18 years+ - NCT03230565RecruitingPhase 4
Continuous vs bolus pain medication through nerve catheter
This study compares two ways of delivering numbing pain medicine through a nerve catheter after surgery: a steady infusion versus scheduled bolus doses. It aims to see which method works better and is easier to use for post-operative pain control.
Stanford, CaliforniaAges 18 years+ - NCT03258580Recruiting
Studying how culture and mind affect how we feel pain
This study looks at how beliefs, mood, and social factors affect how people express and judge pain. It mainly uses pain/heat testing and—if chosen—brain scans to understand why pain reports can differ between people.
Bethesda, MarylandAges 18–60 - NCT03304730Recruiting
Tracking pain patterns after low back joint injections
This study follows adults with long-lasting low back pain to learn what predicts who improves after a specific type of back joint injection. It mainly helps doctors understand which factors relate to better or worse outcomes over time.
São Paulo, São PauloAges 18 years+ - NCT03353584Recruiting
Virtual reality for pain relief during sickle cell pain crises
This trial tests whether a virtual reality (VR) experience can help reduce pain during a sickle cell “vaso-occlusive crisis,” which is an episode of sudden, severe pain. It’s offered alongside the care team’s usual pain management to see if VR makes pain feel better.
Memphis, TennesseeAges 6–25 - NCT03371121Recruiting
AMIC cartilage repair for ankle cartilage damage in adults
This trial studies outcomes after a specific ankle cartilage repair surgery called AMIC. It looks at clinical results and imaging (pictures) after surgery to see how well the treatment works.
MilanAges 18–65 - NCT03409133Recruiting
Neural feedback training for people with leg amputations
This study tests whether a nerve-based “feedback” system can help people with below-knee or above-knee amputations during standing and walking. It focuses on whether the training and device setup are safe and workable for participants over the study period.
Cleveland, OhioAges 18 years+ - NCT03427736Recruiting
Studying pain and numbing medicines in children
This trial looks at how well different numbing and pain-relief medicines work in children during routine care. It may help doctors choose safer, better pain control for kids who need these medicines.
Stanford, CaliforniaAges birth–17 years - NCT03434392Recruiting
Testing pain-sensing to predict treatment response in chronic pancreatitis
This study uses a special pain-testing method to better predict how people with chronic pancreatitis-related pain (or similar conditions) will respond to treatment. It may help doctors choose therapies that work better for each person’s type of pain.
Baltimore, MarylandAges 18 years+ - NCT03489499Recruiting
Genetic testing study of pain after planned surgery
This study looks at whether genetic differences can help predict how much pain you may have after an elective (planned) operation. If you qualify, you may be asked to give consent and share information so researchers can compare pain experiences across people.
BernAges 18 years+ - NCT03490630Recruiting
Survey study after bariatric weight-loss surgery
This study asks adults to complete patient-reported surveys after elective bariatric (weight-loss) surgery. It may help doctors better understand how patients experience recovery and outcomes.
BernAges 18 years+ - NCT03560388Recruiting
Acupuncture and integrative care after gynecologic cancer surgery
This trial studies whether acupuncture and supportive “integrative care” can help people around the time of gynecologic cancer surgery. You may be invited to participate if you’re having surgery for suspected or confirmed gynecologic cancer and can safely take part in the study.
HaifaAges 18 years+ - NCT03596424Recruiting
Testing ketamine and dexmedetomidine during lung surgery
This trial studies whether the anesthesia medicines ketamine and dexmedetomidine can improve care during elective lung (video-assisted) surgery. It may help with comfort during and after the operation, depending on how these medicines affect pain and recovery.
Montreal, QuebecAges 18–80 - NCT03646955Recruiting
Partial breast radiation versus no radiation after lumpectomy
This trial compares giving radiation only to part of the breast versus not giving radiation at all after breast-conserving surgery. It’s meant for women with early, hormone-driven breast cancer to see if skipping radiation can be safe and reduce treatment burden.
SantiagoAges 60 years+ - NCT03675386Recruiting
Help reducing opioid use after surgery for chronic pain
This trial tests a program to help people with long-term (chronic) pain use less opioid medicine after surgery. It may help you reduce opioid doses while still managing your pain.
Toronto, OntarioAges 18 years+ - NCT03695887RecruitingEarly Phase 1
Disposable nitrous oxide for pain during burn dressing changes
This early-stage study tests whether using disposable nitrous oxide canisters can better control pain when you need burn dressing changes. It may help by making dressing changes more comfortable, but eligibility depends on your burn size, health, and breathing ability.
Winnipeg, ManitobaAges 18 years+ - NCT03696134Recruiting
Study of musculoskeletal health, frailty, pain, and disability
This study looks at musculoskeletal health and wellbeing in adults, especially people who are frail or at risk of developing frailty-related problems like pain or limited ability to move. It may help researchers understand what puts people at risk and what could improve comfort and function.
NottinghamAges 18 years+ - NCT03707288Recruiting
Exercise study for neck and low back pain in medical students
This study looks at neck and low back pain in medical students and asks participants to follow a set exercise plan for a period of time. It may help researchers understand what kind of exercise support could improve symptoms in students.
Kingston, KingstonAges Any age - NCT03711773Recruiting
Low-impact exercise classes for joint pain
This study tests a gentle, low-impact exercise program to improve pain and function for adults with knee, ankle, and/or hip pain. You’ll also attend dietitian and behavioral health classes as part of standard care while you participate.
Columbia, MissouriAges 18 years+ - NCT03715517Recruiting
Spinal anesthesia to improve recovery after liver surgery
This trial studies whether using spinal/epidural anesthesia during liver tumor removal surgery can help people recover better and with less pain. It compares this approach to standard general anesthesia care to see if recovery is smoother.
Winnipeg, ManitobaAges 18 years+ - NCT03725527Recruiting
Nerve block test to improve breathing after belly surgery
This trial studies whether a numbing injection near the abdominal muscle (rectus sheath block) helps your breathing and diaphragm function after elective upper belly surgery. If you qualify, you may receive or not receive this pain/nerve block as part of the study.
