This study compares standard root canal retreatment with a regenerative method using injectable platelet-rich fibrin (i-PRF) in 140 adults with persistent tooth infections. Participants are randomly assigned to one of the two treatments and followed for two years to assess healin…

This study aims to determine how accurate physical tests and ultrasound are for diagnosing tennis elbow (lateral elbow tendinopathy). Researchers will compare these methods in 100 adults with elbow pain to see which works best. The goal is to find a reliable, non-invasive diagnos…

This study tests whether injecting the steroid dexamethasone near the tooth ligament or under the gum helps numb the tooth better and reduces pain during root canal treatment. It includes 84 adults with severe, irreversible pulpitis in a lower molar. Participants receive one of t…

This study tests whether a single nerve block injection (erector spinae plane block) can reduce persistent back pain in people with ankylosing spondylitis whose disease activity is already controlled by medication. Fifteen adults aged 18–65 will receive the injection and be monit…

This study tests whether supervised exercise sessions done at home through video calls can improve breathing, fatigue, and quality of life in people with elevated pulmonary artery pressure. Twelve adults with stable symptoms will be randomly assigned to either telerehabilitation …

This study tests whether a physiotherapist-guided online exercise program can reduce pain and improve physical function in remote white-collar workers. Thirty-three participants with low back or neck pain will do supervised exercises twice a week for six weeks. The goal is to see…

This study explores whether people with Parkinson's disease can improve their quality of life, walking speed, and mobility by managing their own exercise plans at home using telerehabilitation. Researchers will compare self-managed exercise to supervised programs in 30 participan…

This study looks at whether avoiding opioids during back surgery can still control pain and reduce side effects like nausea and constipation. About 75 adults having elective lumbar spine surgery will be placed into one of three groups based on their anesthesia plan. The goal is t…

This study tests whether adding special balance exercises to a standard workout of walking and strength training can improve balance and physical fitness in overweight and obese adults. Forty participants will be randomly assigned to either a standard exercise program or one that…

This study looks at whether a steroid injection into the spine can improve how well people with chronic neck pain sense their arm movements. Researchers will give the injection to 46 adults with a pinched nerve in the neck and measure arm position accuracy before and after. The g…

This study looks at how well people with cervical radiculopathy (a pinched nerve in the neck) can sense where their arm is in space. Researchers will compare 58 patients to healthy volunteers using a reaching test on a wall chart. The goal is to see if nerve compression affects a…

This study will check if a new scoring system called SOFA-2 can better predict which ICU patients are likely to die within 30 days, compared to the current standard. Researchers will also measure how common sepsis and septic shock are in Turkish intensive care units. About 2,500 …

This study follows 57 head and neck cancer patients during radiotherapy to monitor their nutritional health. Researchers regularly check body composition, muscle strength, food intake, and quality of life using simple tests and questionnaires. The goal is to spot early signs of m…

This global registry is collecting information from 1,000 people with Takayasu's arteritis, a rare disease that inflames and narrows large arteries. Researchers will analyze patients' symptoms, lab results, imaging, and treatments to see how the disease behaves and is managed aro…

This study looks at how seeing, hearing, and smelling food in a virtual reality (VR) environment changes food cravings and body responses. Thirty-four healthy adults will have their brain activity, saliva, blood sugar, and temperature measured while exposed to real and virtual fo…

This study is translating a sleep screening questionnaire into Turkish and testing how well it works for children with complex chronic conditions. Researchers will enroll 330 children and teens, tracking their sleep at home and during stays in the pediatric intensive care unit. T…

This study looks at how muscle stiffness (spasticity) patterns in the arms and legs of people with multiple sclerosis relate to their quality of life. Researchers will classify these patterns and measure their impact using patient surveys and physical tests. The goal is to better…

This study looks at whether two simple calculations using heart rate and blood pressure can predict which women will experience low blood pressure after receiving spinal anesthesia for planned C-sections. Researchers will monitor 300 women and track how often low blood pressure o…

This study looks at whether nutritional status, measured by the CONUT score, is linked to balance and daily function in people who had a stroke at least 6 months ago. Researchers will assess balance, muscle thickness, and bone density in 47 adults. The goal is to better understan…

This study looks at how metabolic markers like insulin resistance and body measurements relate to pain and central sensitization in women with lipedema. Researchers will assess 59 women using questionnaires and physical measurements. The goal is to better understand these connect…

This study looks at whether the natural pulsation of the spinal cord is linked to pain and disability in people with lumbar spinal stenosis (a narrowing of the spine). Researchers will measure pain, function, and MRI images in 100 adults aged 18-85. The goal is to better understa…

This study looks at whether fear of movement (kinesiophobia) affects how well heart failure patients with a Left Ventricular Assist Device (LVAD) can move and function. Researchers will measure fear levels and physical capacity before and one month after patients leave the hospit…

This study tests whether giving magnesium sulfate during lung surgery helps keep oxygen levels stable and lungs working well. About 104 adults having video-assisted lung surgery with one-lung ventilation will be observed. Researchers will compare those who get magnesium as part o…

This study looks at whether women with lipedema have flatter feet and looser joints compared to women without the condition. Researchers will use foot X-rays and flexibility tests to measure these differences. The goal is to better understand how lipedema affects foot function an…

This study uses ultrasound to look for hidden tendon inflammation in people with tennis elbow (lateral epicondylitis) and compare them to healthy volunteers. Researchers will examine 60 participants to see if those with tennis elbow have more widespread tendon issues. The goal is…
