- NCT04003311Enrolling by invitation
Follow-up for specific shoulder implant types and surgery
This study checks outcomes in people who already received certain Zimmer Biomet shoulder implant components using the correct surgical technique. It may help improve how these specific implants are used and monitored after surgery.

Reverse shoulder implant study for severely damaged rotator cuff
This trial studies a specialized reverse shoulder implant system for people whose rotator cuff is badly damaged or who had a prior shoulder replacement that failed. It aims to reduce pain and improve function by improving how your shoulder works, especially when the rotator cuff can’t do its job.

Testing two ways to numb lumbar back pain with radiofrequency
This study compares two needle-based techniques to treat long-lasting low back pain by stopping overactive pain signals from specific back joints. If you’ve already tried physical therapy and pain medicines without enough relief, this trial may test which technique works better for pain reduction.
Nashville, TennesseeAges 40 years+ - NCT04008173Enrolling by invitation
Survey study of acute heart attack symptoms
This study collects information about symptoms and experiences during acute coronary syndromes, which are sudden, serious heart events like heart attacks or unstable angina. It may help researchers understand patterns of care and symptoms to improve future treatment and support.
Bologna, BolognaAges 18 years+ - NCT04004286Recruiting
Pain registry and blood sample biobank for eligible service members
This trial is building a pain registry biobank to learn more about pain and how different people experience it. If you’re eligible for care in the Military Healthcare System and can consent, you may be able to contribute your information for future research.
San Diego, CaliforniaAges 18–80 - NCT03972124RecruitingPhase 2
Cannabis to prevent migraine attacks before they start
This Phase 2 trial tests whether using cannabis can prevent migraine attacks from happening. It specifically looks at people with chronic migraine who have tried and not benefited from other prevention medicines.
Calgary, AlbertaAges 25 years+ - NCT04025359RecruitingEarly Phase 1
Test dronabinol for pain responses in people on opioid treatment
This early-stage study tests whether dronabinol (a form of THC) changes pain perception in people with opioid use disorder who are already stable on methadone or buprenorphine. It may help researchers understand whether this treatment affects pain and drug-related outcomes in a safer, controlled way.
West Haven, ConnecticutAges 18–70 - NCT03987334Recruiting
Virtual reality rehab for chronic neck pain
This trial studies whether virtual reality exercises can help reduce pain and improve function in people with chronic neck pain or whiplash. You may be invited to take part in guided VR rehab sessions if you meet the safety and health requirements.
Milan, MIAges 18–70 - NCT03906422Recruiting
Study of pain after placing braces archwire
This study compares how much pain people feel after their braces archwire is first put in. It may help orthodontists choose approaches that make the early pain experience easier.
Aurora, ColoradoAges 12 years+ - NCT03936790Enrolling by invitation
Testing ropivacaine dose for C-section in taller adults
This trial studies how different doses of ropivacaine (a numbing medicine given into the spine) affect comfort and safety during an elective C-section in taller, otherwise healthy adults. It may help anesthesiologists choose the right dose for this specific body-size group.
Athens, AtticaAges 20–40 - NCT03747146Recruiting
Enhanced recovery plan for knee replacement pain control
This study tests an “enhanced recovery” approach for people getting total knee replacement, focused on better pain control using regional anesthesia and a home pain medicine plan. It may help you recover more comfortably and follow the care plan more smoothly after surgery.
New York, New YorkAges 18–65 - NCT03834818Recruiting
Using a phone app to track pain after orthopedic surgery
This study collects information about pain and recovery after planned (elective) orthopedic surgery. It uses a smartphone to help understand outcomes and pain levels so care may improve.
Durham, North CarolinaAges 18–90 - NCT03794362Recruiting
Testing how pain medicines change pupils in children
This study looks at how different pain treatments affect a child’s pupils (the dark center of the eye). It may help doctors better understand which pain medicines are working and how to measure pain treatment effects more accurately.
Washington D.C., District of ColumbiaAges 7–21 - NCT03823534RecruitingPhase 3
Study pain control after preventive femur bone surgery
This Phase 3 study tests a pain medicine plan used after preventive surgery to place a metal rod inside the thigh bone (femur) before a fracture happens. The goal is to find an approach that controls post-surgery pain while being safe for the right patients.
St Louis, MissouriAges 18 years+ - NCT03808584Recruiting
Core muscle training after abdominal surgery to reduce hernia and pain
This study tests whether guided “core” muscle training after abdominal surgery can lower the chance of developing an incisional hernia and reduce pain. You may be eligible if you’re having abdominal surgery and can safely do the study exercise plan.
KoblenzAges 18 years+ - NCT03862417Recruiting
Exercise program for adults with degenerative scoliosis pain
This pilot study tests an exercise program to help reduce pain and improve function in adults over 50 with degenerative scoliosis. It may be helpful if your spine curve is in a moderate range and you’re not recently had certain injections or surgery.
Edmonton, AlbertaAges 50 years+ - NCT03796572RecruitingPhase 4
Nerve-block pain relief after a specific elbow bone fracture
This trial studies whether a pain-relief “nerve block” with medicine helps control pain after surgery for a particular type of elbow (humerus) fracture. It may help you feel more comfortable during recovery, compared with standard pain control.
Los Angeles, CaliforniaAges 4–12 - NCT03836248Recruiting
Osteopathic care added to standard treatment for chronic low back pain
This study tests whether adding osteopathic treatment to usual medical care can improve chronic low back pain. It focuses on people whose back pain has no clear structural cause and has lasted more than 3 months.
ToulouseAges 18–64 - NCT03737292RecruitingPhase 4
Numbing medicine for chest surgery pain after small lung operations
This trial tests whether a long-lasting numbing shot (liposomal bupivacaine) works better than a regular numbing shot (plain bupivacaine) for pain after minimally invasive chest surgery. It may help you have less post-surgery pain and potentially use less pain medication.
Hershey, PennsylvaniaAges 18 years+ - NCT03794466Recruiting
Study pain relief after blocking gonadal veins for pelvic congestion
This study looks at how much pelvic pain improves after a procedure called gonadal vein embolization (blocking problem veins). It mainly applies to people diagnosed with pelvic congestion syndrome caused by venous (vein) problems, treated during a specific time window.
Kansas City, KansasAges 18 years+ - NCT03829631Recruiting
Test of a back brace for non-dangerous low back pain in ER
This trial studies whether using a lumbar brace in the emergency department helps people with non-serious low back pain recover better. You may be asked to try the brace when you come to the ER for back pain that is not caused by a dangerous underlying condition.
PerthAges 18–65 - NCT03858231RecruitingPhase 4
Opioid vs non-opioid pain relief after knee arthroscopy
This study compares opioid pain medicine with non-opioid pain medicine after arthroscopic (keyhole) knee surgery. It aims to see which approach controls pain well while keeping side effects and risks lower.
Fargo, North DakotaAges 18–80 - NCT03581318Recruiting
Heart MRI study for people with and without heart disease
This study uses magnetic resonance imaging (MRI) to take detailed pictures of the heart. It aims to improve how doctors use heart MRI to diagnose and manage heart conditions.
Bethesda, MarylandAges 7–100 - NCT03584815Recruiting
Test of physiotherapy versus surgery for exercise leg muscle pressure
This trial compares a physiotherapy program to a surgical procedure (fasciotomy) for chronic “compartment” pressure in the lower leg triggered by exercise. If you have symptoms that reliably come on with walking/running and improve with rest, the study may offer a structured way to find the best treatment for you.
