Radio waves for muscle or low back pain and function
This trial tests whether a high-frequency radio-wave treatment can reduce pain and improve movement in adults with a muscle strain (hamstring) or acute or chronic low back pain. It may help you feel less pain and function better, depending on your specific injury and medical details.
KavalaAges 18–65 - NCT04546685Recruiting
Spanish online group program to help manage long-term pain
This trial tests a one-time, Spanish-language online group program (“Empowered Relief”) for people with long-term pain. It may help you learn coping skills and strategies to reduce the impact of chronic pain.
Palo Alto, CaliforniaAges 18 years+ - NCT05279092RecruitingPhase 2
Testing two pain-control injections for knee replacement surgery
This Phase 2 study compares two ways of reducing nerve pain after knee replacement surgery (total knee arthroplasty). It looks at whether steroid-enhanced pain medicine works better than a different numbing injection to improve recovery and comfort.
New Haven, ConnecticutAges 18 years+ - NCT05285683RecruitingPhase 2
Study brain dopamine in people with chronic pain
This Phase 2 study looks at how a brain chemical called dopamine is involved in long-lasting pain. You may be able to join if you have chronic pain for over a year and your pain score is high enough, and if MRI and health checks are safe for you.
Rochester, New YorkAges 18 years+ - NCT05272488Recruiting
Manual therapy plus vagus nerve stimulation for jaw muscle pain
This trial tests whether combining hands-on jaw treatment with a vagus nerve stimulator can reduce jaw muscle pain and improve jaw movement. It may help people whose jaw pain has been present recently and who have not had recent physiotherapy.
Alcalá de Henares, MadridAges 18 years+ - NCT05303415Recruiting
Low-intensity ultrasound study during brain MRI
This study tests how low-power focused ultrasound changes brain signals measured during MRI. You may help researchers understand how ultrasound can affect brain activity, even if you don’t have a known brain condition.
Roanoke, VirginiaAges 18–65 - NCT05267093Recruiting
Acupuncture for hand osteoarthritis pain
This study compares real acupuncture to sham (placebo) acupuncture to see which one better reduces pain and improves function in people with hand osteoarthritis. It may help you understand whether acupuncture provides meaningful relief beyond placebo.
BeijingAges 18–80 - NCT05265000Recruiting
Skin electrical stimulation for chronic low back pain
This study tests whether a gentle electrical treatment placed on the skin near the spine can reduce chronic low back pain. If you qualify, you’ll try the stimulation and complete several assessments over a day, so the team can measure any pain and function changes.
San Francisco, CaliforniaAges 21–85 - NCT05269628RecruitingPhase 2
Cannabidiol for multiple sclerosis sleep and pain patterns
This study looks at whether cannabidiol (CBD, a cannabis-related medicine) can improve symptoms in people with multiple sclerosis (MS), especially how sleep and pain type affect outcomes. It’s mainly for people with MS and ongoing moderate-to-severe pain, while carefully checking safety and medication interactions.
Ann Arbor, MichiganAges 18–65 - NCT05260320Recruiting
Testing the best anesthesia plan for teens having jaw surgery
This study looks at whether a standardized anesthesia plan works best for kids and teens having Le Fort jaw surgery at Johns Hopkins. If you qualify, the team may use or adjust anesthesia to improve safety and comfort during surgery.
Baltimore, MarylandAges 14 years+ - NCT05279547Recruiting
Bed-cycle exercise study to test muscle oxygen during ICU care
This trial tests whether brief “interval” bed-cycling changes how well your leg muscles use oxygen compared with steady cycling. It’s meant for carefully selected ICU patients who can safely do active cycling while on ventilator support.
LeuvenAges 18 years+ - NCT05306899RecruitingPhase 3
IV ketamine for chronic daily headaches
This trial tests whether an IV dose of ketamine can reduce chronic daily headaches and is safe for people with this condition. It may help by lowering headache frequency and severity, but it also has several medicine and health-related safety checks.
Toronto, OntarioAges 18–75 - NCT05278494Recruiting
Dextromethorphan to reduce pain after knee replacement
This trial studies whether dextromethorphan (a medicine sometimes used for cough) can reduce pain after total knee replacement surgery. If you’re having this operation and meet safety criteria, it may help improve how you feel during recovery.
Los Angeles, CaliforniaAges 18 years+ - NCT05285566RecruitingPhase 4
Pain control during rib cartilage nose surgery

Robotic vs standard knee replacement for inner-joint wear
This trial compares robotic-assisted knee replacement with the usual (non-robotic) approach for people with severe arthritis on the inner (medial) side of the knee. It aims to see which method works better for pain and function while matching the right knee anatomy for certain implant types.
Edinburgh, LothianAges 50–75 - NCT05231265Recruiting
Lumbar surgery effect on walking complexity in chronic low back pain
This study looks at how lumbar spine surgery (fusion or artificial disc “prosthesis” on one or two levels) affects how complex your walking looks and feels. It may help doctors better understand what to expect from surgery and how it changes movement in people with long-term low back pain.
