Neck Position Sense and Balance in Students With Rounded Shoulders
This study examines how neck position awareness, core strength, and balance are affected in university students with Upper Crossed Syndrome—a posture problem involving forward head position and rounded shoulders. The research may help identify better treatments for chronic neck pain linked to poor posture.

Surgery plan for pain or skin problems in a healed leg stump
This study looks at a surgical approach for people who already had an above-knee or below-knee amputation and now have ongoing pain or skin/stump problems that haven’t improved. It aims to improve comfort and how well the stump area heals, assuming you’re healthy enough for surgery under standard anesthesia.
Bethesda, MarylandAges 18–65 - NCT04059172RecruitingEarly Phase 1
Ibuprofen plus acetaminophen for braces pain
This early study compares braces pain relief using: ibuprofen alone, ibuprofen plus acetaminophen together, or placebo (no active pain medicine). It may help find which approach works best and is safest for people starting orthodontic treatment.
Aurora, ColoradoAges 12–80 - NCT04074798Recruiting
Breathing over fast and slow movements for back pain
This study tests how breathing changes (hyperventilation) might affect people with long-lasting low back pain. It may help researchers understand triggers or symptoms, and compare them to people who do not have back pain.
HasseltAges 20–60 - NCT04075539RecruitingPhase 3
At-home cycling for lumbar spinal stenosis pain
This study tests whether an at-home cycling program can reduce leg and back pain caused by lumbar spinal stenosis. It aims to see if regular, supervised cycling helps people walk and function better.
Paris, Île-de-France RegionAges 50 years+ - NCT04081896Recruiting
Rehab program for adults with spine pain
This trial studies whether a prescribed physical therapy (rehab) program helps people with spine pain. It may help by improving pain and function when a clinician has already recommended rehabilitation.
San Diego, CaliforniaAges 18–89 - NCT04095117Recruiting
Measure belly size to predict epidural depth in obesity
This study checks whether a measurement of belly size can help predict how deep an epidural needs to go in people with obesity. It may help make epidural placement safer and more accurate during planned leg surgeries.
CairoAges 18 years+ - NCT04102566RecruitingPhase 4
Better pain control during TURP surgery
This trial tests whether a pain-control approach can make TURP (prostate surgery through the urine tube) more comfortable. It may help you manage pain with the study medicines during and after your procedure.
Seattle, WashingtonAges 18 years+ - NCT04109638Recruiting
PEMF therapy to reduce pain after shoulder or knee surgery
This trial studies whether PEMF, a type of non-surgical device that uses pulsed electromagnetic fields, can reduce pain after shoulder or knee surgery. If you join, you’ll also be expected to do post-surgery physical therapy exercises and report your pain and function.
Redwood City, CaliforniaAges 18 years+ - NCT04109365Recruiting
Study of epidural placement technique during labor
This trial studies an approach to placing an epidural (pain medicine placed near the spine) during early labor. It aims to improve how safely and accurately epidurals are positioned, which may help with comfort during childbirth.
Palo Alto, CaliforniaAges 18 years+ - NCT04128670Recruiting
Kinesio tape test for sore muscles after exercise
This study checks whether Kinesio tape changes how sore your muscles feel after workouts. You may help researchers learn if the tape reduces “delayed onset muscle soreness” after upper-body activity.
Indianapolis, IndianaAges 18–30 - NCT04130464RecruitingPhase 4
Analgesic placed inside the belly for after-surgery pain
This study tests whether placing a pain medicine inside the abdomen during hysterectomy can reduce postoperative pain. It targets people having specific types of minimally invasive hysterectomy for non-cancer reasons.
Washington D.C., District of ColumbiaAges 18–65 - NCT04134702Recruiting
Acupuncture for less pain after outpatient knee surgery
This study tests whether acupuncture can reduce pain after outpatient arthroscopic knee surgery done under general anesthesia. It may help by improving pain control while avoiding certain medicine side effects, but you must meet several specific safety and medication limits.
Greifswald, VorpommernAges 19–55 - NCT04142177Recruiting
Test which pain treatments work best for chronic low back pain
This study compares how well different pain treatments reduce low back pain and improve daily life. You may be asked to start or continue care through the VA and attend in-person sessions while completing pain and activity questionnaires.
Phoenix, ArizonaAges 18 years+ - NCT04144972Recruiting
Closed-loop deep brain stimulation for long-lasting nerve pain
This trial tests a “smart” deep brain stimulation device that senses your brain signals and adjusts treatment to reduce severe, long-lasting pain. It may help people whose pain has not improved with multiple pain medicines and surgery cannot fix the cause.
San Francisco, CaliforniaAges 22–80 - NCT04164225Recruiting
Testing how qigong affects brain activity in chronic low back pain
This study looks at how doing qigong may change brain activity and physical symptoms in adults with long-lasting low back pain. It’s mainly to see whether the brain and symptom measures can be identified and tracked after qigong practice.
Minneapolis, MinnesotaAges 18–70 - NCT04166877RecruitingPhase 4
Magnesium drip to reduce pain in ICU trauma patients
This trial tests whether a magnesium infusion can better control pain in adults who have serious injuries and need intensive care. It compares magnesium as part of pain treatment to standard pain care to see if pain improves and stays controlled.
Sacramento, CaliforniaAges 18 years+ - NCT04189965Recruiting
Study of long-term memory of pain in healthy adults
This study looks at how people remember pain over time. It enrolls healthy adults so researchers can better understand the long-term effects of painful experiences.
BronAges 18–50 - NCT04193475Recruiting
Uses computer learning to improve stress heart ultrasound
This study uses computer technology (“machine learning”) with stress echocardiogram images (a heart ultrasound done during stress) to improve how heart function is measured. If you are able to have a stress echocardiogram, you may be able to help test a better way to interpret the results.
CottinghamAges 20–89 - NCT04196244RecruitingPhase 4
IV-contrast CT vs no-contrast CT for urgent abdominal pain
This study compares two types of CT scans—using IV contrast dye versus not using dye—in people who need an emergency abdominal scan but have reduced kidney function. It aims to see which approach is safer and works well enough to help doctors find the cause.
EspooAges 18 years+ - NCT04208828Recruiting
IVIG for difficult gastrointestinal auto-immune nerve symptoms
This trial tests intravenous immunoglobulin (IVIG), a donated antibody treatment, for people whose gastrointestinal (GI) “motor” symptoms are not improving with standard care and may be auto-immune related. If you’re eligible, IVIG could help calm the immune system and improve gut movement symptoms.
Louisville, KentuckyAges 12–90 - NCT04209504Recruiting
Nerve block study for one-sided breathing muscle weakness after shoulder surgery
This trial tests whether a longer-lasting nerve block during shoulder surgery can better manage pain and affect one-sided diaphragm (breathing muscle) weakness. It may help people having planned (first-time) shoulder surgery who are able to follow study pain-checks.
