Clinical trials

This study evaluates the postoperative pain and long-term clinical and radiographic success of single-visit primary root canal treatment in asymptomatic teeth with periapical lesions.

This observational study aims to examine the relationships between pain catastrophizing, fear of movement, and physical activity in postmenopausal women with chronic nonspecific low back pain. Pain catastrophizing refers to negative thoughts and feelings about pain, while fear of movement refers to concerns that movement may cause pain or injury. The study will include 150 naturally postmenopausal women aged 45-65 years who have experienced nonspecific low back pain for at least three months. Participants will attend a single face-to-face assessment conducted by a trained physiotherapist. Questionnaires will assess physical activity, pain catastrophizing, fear of movement, low back pain intensity, disability symptoms. Functional mobility and lower-limb functional performance will be assessed using the Timed Up and Go test and the 30-second chair stand test. The primary objective is to examine the joint association of pain catastrophizing and fear of movement with physical activity, accounting for relevant clinical and psychological factors. Secondary objectives concern disability and physical performance. No treatment will be assigned as part of the study.

This study will evaluate whether adding mental rehearsal of pelvic floor muscle contractions to pelvic floor muscle training improves stress urinary incontinence in postmenopausal women. Stress urinary incontinence is urine leakage during activities such as coughing, sneezing, or physical exertion. Mental rehearsal involves imagining the sensation of a movement without physically performing it. The study will include 60 women aged 45 to 65 years who have completed natural menopause and have stress urinary incontinence. Participants will be randomly assigned to one of two groups. Both groups will receive the same supervised pelvic floor muscle training twice a week for 12 weeks. Before performing the pelvic floor exercises, one group will imagine contracting and relaxing the pelvic floor muscles. The other group will imagine making and opening a fist with their dominant hand. Assessments will take place before treatment and at the end of 12 weeks. The main outcome will be urinary incontinence symptom severity. Additional assessments will examine urine leakage frequency and amount, incontinence-related quality of life, and pelvic floor muscle electrical activity.

Chronic non-specific neck pain (CNSNP) is a widespread musculoskeletal condition leading to pain, disability, and impaired quality of life. Due to its multifactorial nature involving biomechanical, sensorimotor, and psychosocial aspects, various rehabilitation interventions have been recommended. However, there is a lack of direct evidence comparing structured exercise, sensorimotor training, and pain neuroscience education within a comprehensive biopsychosocial framework. The primary objective of this randomized controlled trial is to evaluate and compare the effectiveness of structured exercise, sensorimotor training, and pain neuroscience education on disability, pain intensity, sensorimotor control, and psychosocial outcomes in individuals with CNSNP. Participants aged 18-65 with chronic non-specific neck pain will be randomly allocated into three intervention groups: Structured Exercise Group (SEG): Cervical stabilization, isometric/isotonic exercises, stretching, and range of motion training. Sensorimotor Training Group (SMTG): Cervical joint position sense retraining, oculomotor exercises, and balance training. Pain Neuroscience Education Group (PNEG): Online educational sessions focused on pain neurophysiology, central sensitization, and cognitive-behavioral strategies. Outcomes will be assessed at baseline (T0), completion of 8 weeks of intervention (T1), and 4 weeks post-intervention follow-up (T2, 12th week).

Anterior cervical discectomy and fusion (ACDF) is a commonly performed surgical procedure for cervical disc herniation, cervical radiculopathy, and degenerative cervical spine disorders. Although surgery may reduce pain and neurological symptoms, some patients experience swallowing difficulties, neck pain, restricted neck movement, reduced respiratory muscle strength, and impaired quality of life after surgery. The purpose of this randomized controlled study is to determine whether a structured postoperative rehabilitation program improves swallowing function, respiratory muscle strength, pulmonary function, neck-related disability, pain, cervical range of motion, and health-related quality of life in adults who have undergone single- or two-level ACDF. A total of 60 eligible participants will be randomly assigned in a 1:1 ratio to either a structured rehabilitation group or a standard postoperative follow-up group. The structured program will include breathing exercises, inspiratory muscle training, swallowing and safe feeding education, cervical and scapular exercises, postural training, upper-extremity exercises, walking, and gradual physical activity. Participants in the control group will receive the standard postoperative recommendations provided by the surgical team. Assessments will be conducted before the rehabilitation program and during postoperative follow-up. The primary outcome will be swallowing difficulty measured using the Eating Assessment Tool-10. Additional outcomes will include dysphagia severity, oral intake level, respiratory muscle strength, spirometric pulmonary function, neck pain, neck-related disability, cervical range of motion, health-related quality of life, treatment adherence, and adverse events.

Carpal tunnel syndrome can cause hand pain, numbness, weakness, sleep disturbance, fatigue, fear of movement, and difficulty performing daily activities. Carpal tunnel release surgery is commonly performed when symptoms are severe or do not improve with conservative treatment. However, recovery after surgery may involve changes not only in hand symptoms but also in sleep, fatigue, fear of movement, pain, and upper extremity function. The aim of this prospective observational study is to evaluate how sleep quality, fatigue, kinesiophobia, pain, carpal tunnel syndrome-related symptoms, and upper extremity function change after carpal tunnel release surgery. Adults scheduled for unilateral primary carpal tunnel release surgery as part of their routine clinical care will be invited to participate. The researchers will not assign or modify the surgical procedure, medication, rehabilitation, or other clinical treatment. Participants will be evaluated before surgery and at 4 and 8 weeks after surgery. Sleep quality will be assessed using the Pittsburgh Sleep Quality Index. Fatigue, kinesiophobia, upper extremity function, carpal tunnel syndrome-related symptoms, and pain will be assessed using the Fatigue Severity Scale, Tampa Scale of Kinesiophobia, QuickDASH, Boston Carpal Tunnel Questionnaire, and Numeric Rating Scale, respectively. The study will examine changes in these outcomes over time and investigate whether improvements in sleep and fatigue are associated with reductions in pain, kinesiophobia, and carpal tunnel syndrome symptoms and with improvements in upper extremity function.

Carpal tunnel syndrome occurs when the median nerve is compressed at the wrist. It can cause pain, numbness, tingling, reduced hand strength, and difficulty performing daily activities. Carpal tunnel release surgery is commonly performed when symptoms do not improve with conservative treatment or when nerve compression is severe. However, recovery after surgery may differ between patients, and improvement in nerve conduction may not occur at the same rate as improvement in symptoms and hand function. The purpose of this prospective observational study is to examine the relationship between electrophysiological recovery of the median nerve and clinical and functional recovery after carpal tunnel release surgery. Adults who are already scheduled to undergo primary carpal tunnel release as part of their routine clinical care will be invited to participate. The decision to perform surgery will be made by the treating physician independently of study participation. Participants will undergo clinical and functional assessments before surgery and at postoperative week 8 These assessments will include questionnaires about carpal tunnel symptoms and upper-extremity function, pain severity, grip and pinch strength, sensory testing, and clinical examination. Nerve conduction studies will be evaluated before surgery and at postoperative month 3. The study will assess whether changes in median nerve conduction are associated with changes in symptoms, upper-extremity function, pain, hand strength, and sensory function. The possible effects of age, sex, body mass index, symptom duration, diabetes, and preoperative electrophysiological severity on recovery will also be examined. No experimental drug, device, surgical technique, or additional treatment will be assigned as part of this study.

Posterior spinal instrumentation can cause significant postoperative pain due to extensive muscle dissection, manipulation of bone tissue, and implant placement. Providing optimal analgesia in the postoperative period is important for patients' functional recovery and early mobilization. Inadequate control of postoperative pain may delay recovery, increase the risk of opioid dependence, and lead to respiratory complications. Although opioid analgesics are effective in reducing pain during the postoperative period, they are associated with side effects such as nausea, vomiting, respiratory depression, and the risk of dependence. Therefore, the use of non-opioid analgesic approaches is important for patient safety and comfort. For these reasons, regional analgesia techniques such as the modified thoracolumbar interfascial plane (TLIP) block and the erector spinae plane (ESP) block have recently become increasingly popular for postoperative pain control. The quadro-iliac plane block is a novel technique that targets the attachment area of the posterior surface of the quadratus lumborum muscle on the inner surface of the iliac crest. In this block, the spread of local anesthetic along the fascial planes surrounding the quadratus lumborum muscle may provide an anatomical mechanism contributing to analgesia of the lumbosacral, paraspinal, lower abdominal, and gluteal regions. However, as the quadro-iliac plane block is a new technique, there are not yet sufficient studies on this topic in the literature. The primary objective of our study is to evaluate the effect of ultrasound-guided quadro-iliac plane block (QIPB) on postoperative opioid consumption after posterior spinal instrumentation. The secondary objectives are to compare opioid-related side effects, such as nausea, vomiting, and respiratory depression, as well as postoperative NRS (Numeric Rating Scale) pain scores between the groups.

The goal of this clinical trial is to compare adductor canal block and parasartorial compartment block for pain relief and functional recovery in adults undergoing elective arthroscopic knee surgery. The main questions it aims to answer are: Which block provides better pain relief at rest and during movement 24 hours after surgery? How do the two blocks compare in opioid use, muscle strength, knee movement, early walking, side effects, and patient satisfaction? Researchers will compare participants who receive an adductor canal block with those who receive a parasartorial compartment block to determine whether one technique provides better pain relief and functional recovery while preserving muscle strength. Participants will: Be randomly assigned to receive either an ultrasound-guided adductor canal block or an ultrasound-guided parasartorial compartment block Have their pain at rest and during knee movement assessed for 48 hours after surgery Have their opioid use, quadriceps muscle strength, knee movement, walking ability, side effects, and satisfaction evaluated after surgery

The goal of this observational study is to compare physical findings across three adult groups. Cervicogenic headache (CGH) is a headache linked to a problem in the neck. Neck pain may affect posture, muscle function, grip strength, and sensitivity to pressure. Researchers do not know whether CGH has a distinct pattern of these findings. The main questions are: * Do posture, grip strength, muscle stiffness, elasticity, and pressure sensitivity differ among the groups? * Are any differences more closely associated with CGH than with neck pain? Researchers will compare adults ages 25 through 60. One group will include people with CGH lasting at least three months. Another group will include people with neck pain lasting at least six months. People in the neck pain group will have no headaches. Healthy participants will have no neck pain or headaches. Researchers will not provide treatment or change participants' usual care. Each participant will complete one study visit lasting about 15 minutes. Participants will: * Answer short questions about their health and pain * Stand while researchers measure their head and neck posture * Squeeze a device that measures grip strength * Complete brief tests of neck muscle stiffness and elasticity * Tell researchers when applied pressure first becomes painful Researchers will compare results across the three groups. The findings may guide future CGH assessment and treatment research.

This randomized, assessor-blinded, four-arm, parallel-group controlled trial aims to compare the effects of vibration therapy, abdominal massage, and myofascial release with an education-only control intervention in women with primary dysmenorrhea. Seventy-two women aged 18 to 30 years will be randomized in a 1:1:1:1 ratio. All participants will receive standard education about primary dysmenorrhea. The three intervention groups will additionally receive their assigned treatment twice weekly for 12 weeks, covering three menstrual cycles. Menstrual pain, pain characteristics, pressure pain threshold, menstrual symptoms, and symptoms associated with central sensitization will be evaluated at baseline and after the intervention by a blinded assessor.

Brief Summary This randomized controlled trial will compare the immediate effects of three warm-up protocols on physical performance in male amateur basketball players. A total of 45 licensed basketball players aged 15 to 25 years will be randomly assigned to one of three groups: standard dynamic warm-up, dynamic warm-up followed by classical hold-relax proprioceptive neuromuscular facilitation (PNF) stretching, or dynamic warm-up followed by short-duration self-administered PNF stretching. The main outcome will be the change in countermovement jump height. Additional outcomes will include flexibility, knee range of motion, squat jump height, 20-meter sprint time, agility, dynamic balance, and perceived exertion. Measurements will be performed before the assigned warm-up protocol, immediately after the protocol, and 15 minutes after the protocol. The study aims to determine whether short-duration self-PNF stretching can improve flexibility while preserving performance more effectively than classical PNF stretching. Each participant will complete the assigned protocol and all assessments during a single study session.

This randomized controlled trial aims to compare the effectiveness of early mobilization alone versus early mobilization combined with electrical stimulation on functional recovery following lumbar disc herniation surgery. Lumbar disc herniation is a common cause of low back pain and functional limitation, significantly affecting quality of life. Although surgical intervention is effective in patients who do not respond to conservative treatment, optimal postoperative recovery largely depends on appropriate rehabilitation strategies. Early mobilization is widely recommended to prevent complications, preserve muscle function, and facilitate return to daily activities. In addition, electrical stimulation modalities such as neuromuscular electrical stimulation (NMES) and transcutaneous electrical nerve stimulation (TENS) have been increasingly integrated into rehabilitation programs to enhance pain control, muscle activation, and neuromuscular re-education. In this study, a total of 60 participants who have undergone primary lumbar disc herniation surgery will be randomly assigned into two groups. The first group will receive an early mobilization program alone, while the second group will receive early mobilization combined with electrical stimulation (NMES/TENS). The intervention period will last 6 to 8 weeks, with sessions conducted three times per week. Primary outcomes include functional disability measured by the Oswestry Disability Index (ODI) and pain intensity measured by the Visual Analog Scale (VAS). Secondary outcomes include functional mobility assessed by the Timed Up and Go (TUG) test, walking speed assessed by the 10-Meter Walk Test (10MWT), and muscle strength evaluated using manual muscle testing (MMT). The findings of this study are expected to contribute to the development of evidence-based postoperative rehabilitation protocols and to clarify the clinical effectiveness of electrical stimulation in patients undergoing lumbar disc herniation surgery

This randomized controlled trial aims to evaluate the effectiveness of topical paraffin oil application in preventing tourniquet-related skin lesions in patients undergoing upper extremity surgery. Pneumatic tourniquets are commonly used to provide a bloodless surgical field; however, they may cause skin complications such as erythema, edema, abrasions, blisters, and burns. In this study, adult patients undergoing elective upper extremity surgery will be randomly assigned to either an intervention group receiving topical paraffin oil application in addition to routine protective dressing or a control group receiving routine care only. Skin integrity will be assessed immediately after tourniquet removal and at 30 and 60 minutes postoperatively using standardized skin assessment criteria. The findings of this study are expected to contribute to the development of effective, simple, and cost-efficient strategies to prevent tourniquet-related skin complications and improve patient safety and postoperative comfort.

This prospective observational study aims to investigate the effects of a multidomain community-based support program on cognitive function and quality of life in older adults attending the Vefahane Life Center in Istanbul, Türkiye. The study will compare elderly individuals actively participating in community-based social, cognitive, physical, and supportive activities with individuals registered at the center but not actively participating during the study period. Participants will undergo neuropsychological and psychosocial assessments at baseline and after 3 months. The primary outcome is change in global cognitive performance measured by the Mini Mental State Examination (MMSE). Secondary outcomes include memory, executive functions, depression, neuropsychiatric symptoms, and quality of life measures.

This study aims to investigate the effects of a proprioceptive neuromuscular facilitation (PNF)-based lower extremity rehabilitation program on balance, gait performance, functional independence, and quality of life in individuals with stroke. Stroke is a leading cause of long-term disability and is commonly associated with impairments in motor control, balance, and walking ability, which negatively affect independence and daily functioning. In this randomized controlled trial, participants with stroke will be randomly assigned to either a PNF-based rehabilitation group or a control group receiving conventional physiotherapy. The intervention will focus on lower extremity PNF techniques to improve motor control, balance, and gait performance. Assessments will be conducted at baseline and at the end of the intervention period. The findings are expected to contribute to the development of evidence-based rehabilitation strategies for individuals with stroke.

Spinal cord injury (SCI)-related paraplegia is a complex neurological condition characterized by motor impairment, increased spasticity, and significant functional limitations in daily activities. Spasticity is one of the most common secondary complications after upper motor neuron lesions and can negatively affect rehabilitation outcomes, gait ability, and functional independence. This randomized controlled study aims to investigate the effects of Functional Electrical Stimulation (FES) applied to the quadriceps muscle in individuals with paraplegia. Participants will be randomly assigned to either a control group receiving conventional neurorehabilitation or an intervention group receiving additional FES treatment. The primary outcomes include changes in spasticity level, quadriceps muscle strength, and functional mobility. Spasticity will be assessed using the Modified Ashworth Scale (MAS), muscle strength will be evaluated with Manual Muscle Testing (MMT), and functional mobility will be measured using the Spinal Cord Independence Measure (SCIM), Timed Up and Go Test (TUG), and 6-Minute Walk Test (6MWT). The intervention period will last 8 weeks, with standardized rehabilitation programs applied to both groups. The FES group will additionally receive quadriceps stimulation with specific neuromuscular electrical stimulation parameters. The findings of this study are expected to provide evidence regarding the effectiveness of FES as an adjunct to conventional rehabilitation in improving motor function and functional independence in individuals with paraplegia.

The goal of this clinical trial is to compare the effects of somatostatin and terlipressin on lowering portal pressure in patients with portal hypertension undergoing liver transplantation, and to investigate whether there are differences in clinical outcomes between the two drugs. The study will evaluate the decrease in portal pressure from baseline following drug administration at defined time points. It will also compare the effects of these drugs on hemodynamics, bleeding, and transfusion requirements. After baseline intraoperative direct portal pressure measurement, a bolus dose of the study drug will be administered, followed by continuous intravenous infusion intraoperatively and for 24 hours postoperatively. Direct portal pressure will be measured again 5 minutes after the bolus dose, after the portal vein anastomosis, after the hepatic artery anastomosis, and, if performed after splenic artery ligation. Hemodynamic parameters will be recorded, and the drugs will be compared in terms of their intraoperative hemodynamic effects. As elevated portal pressure is associated with increased bleeding, intraoperative blood loss and transfusion needs will also be assessed between the groups. Patients will be followed for 7 days postoperatively for clinical and laboratory outcomes.

This study primarily aims to evaluate the impact of a 12-week peer role-play simulation model on the professional development of undergraduate physiotherapy students. Unlike traditional teacher-led case discussions, this study explores the effect of active participation in clinical scenarios, in which students alternate between the roles of 'clinician' and 'patient', on their academic achievement, self-efficacy and perceived clinical readiness. Specifically, the study aims to determine whether this interactive, low-cost pedagogical approach is a superior alternative to conventional lecture-based methods for preparing students for real-world clinical environments, particularly in high-enrolment academic settings.

This study aims to evaluate the effectiveness of extracorporeal shock wave therapy (ESWT) in individuals with lower limb spasticity following stroke. Spasticity is a common complication after stroke and can negatively affect walking ability, mobility, and quality of life. Participants will be randomly assigned to one of two groups. Both groups will receive a standard physiotherapy and rehabilitation program. In addition, the intervention group will receive ESWT applied to the lower limb muscles, while the control group will receive a sham (placebo) ESWT application. The treatment program will be conducted three times per week for four weeks. Clinical assessments will be performed at baseline, after treatment, and during follow-up. The main outcomes of the study include muscle tone (spasticity), walking performance, motor function, and quality of life. The results of this study may help improve rehabilitation strategies and provide evidence for the use of ESWT in stroke patients.

This randomized controlled trial aims to evaluate the effectiveness of mentholated ointment massage in reducing pain and anxiety levels in patients who have undergone coronary bypass surgery, volunteered to participate in the study, and met the inclusion criteria. Group 1: Back massage with mentholated ointment (Vicks) Group 2: Back massage with paraffin oil Group 3 (Control): Routine clinical treatment The comparison group consists of the group receiving a back massage with paraffin oil and the control group (routine clinical treatment). The questions it aims to answer are: H1: Back massage with mentholated ointment after coronary artery bypass graft surgery reduces back pain levels compared to patients receiving routine treatment. H2: Back massage with paraffin oil after coronary artery bypass graft surgery reduces back pain levels compared to patients receiving routine treatment. H3: Back massage with mentholated ointment after coronary artery bypass graft surgery reduces anxiety levels compared to patients receiving routine treatment. H4: Back massage with paraffin oil after coronary artery bypass graft surgery reduces anxiety levels compared to patients receiving routine treatment. H5: Back massage with mentholated ointment after coronary artery bypass graft surgery reduces back pain levels compared to back massage with paraffin oil. H6: Back massage with mentholated ointment after coronary artery bypass graft surgery reduces anxiety levels compared to back massage with paraffin oil. Pain intensity and vital signs will be monitored in all participants before surgery, at 0 minutes (before analgesia administration), and at 30 minutes after surgery. Additionally, vital signs will be observed before the back massage at 0 minutes and after at 15 minutes. Anxiety levels will be measured before surgery and 15 minutes after the back massage application. A total of 5 back massage applications will be performed until the patients are discharged.

Orthorexia Nervosa (ON); is a condition characterized by individuals being overly focused on healthy eating habits, constantly checking and classifying the foods they will consume. ON has not yet been clinically defined as an eating disorder or in a different category, and has not been included in DSM-5. Cognitive flexibility can be defined as a person's ability to quickly change their thinking and behaviors to adapt to different situations and changing conditions. It has been reported that cognitive flexibility skills are impaired in ON. There is evidence that tDCS, a neuromodulation method, increases cognitive flexibility skills. On the other hand, although there are EEG studies on eating disorders, there is no EEG study directly studying ON, and there is no information on the EEG profiles of individuals with high ON scores. For this reason, EEG studies on eating disorders and obsessive behaviors are generally generalized to orthorexia nervosa and are interpreted. This study aims to compare the EEG oscillations and cognitive flexibility skills of individuals with high ON scores with a control group and to examine the effects of anodal tDCS application on these two variables. For this purpose, a total of 48 individuals, 24 healthy and 24 high ON scores, will be included in the study. Participants will be randomly assigned to tDCS experimental and control groups. Therefore, 48 participants will be divided into 4 different subgroups of 12 people each. Data collection tools will be Informed Consent Form, Demographic Information Form, Beck Depression Inventory, Orthorexia Nervosa Test (TON-17), Cognitive flexibility task. First, participants will be subjected to a cognitive flexibility task by taking simultaneous EEG recordings, then tDCS stimulation will be initiated (active or sham) and after stimulation, a cognitive flexibility task will be performed by taking simultaneous EEG recordings again. EEG analyses will be performed using the Brain-Vision Analyzer program. Repeated Measures Analysis of Variance (within-group and between-groups) will be used in statistical analyses.

The aim of this study will be to investigate the effects of Instrument-Assisted Soft Tissue Mobilization (IASTM), applied in addition to a conventional exercise program, on pain, range of motion, proprioception, functionality, and quality of life in individuals with Subacromial Impingement Syndrome (SIS).

The aim of this study is to investigate the effects of Instrument-Assisted Soft Tissue Mobilization and vibration massage therapy on pain, functionality, and kinesiophobia in individuals with lumbar disc herniation.

This study was planned to examine the validity and reliability of the Turkish version of the Situational Vertigo Questionnaire (SVQ), which is used to evaluate dizziness symptoms frequently seen in vestibular pathologies and triggered by visual or environmental stimuli. The research is designed as a methodological scale adaptation and psychometric evaluation study. The study plans to include individuals aged 18 and over who can read and understand Turkish and have complaints of situational dizziness. The Turkish adaptation process of the SVQ will be carried out using the back-and-forth translation method; a pilot application will be conducted after ensuring linguistic and cultural equivalence. For the psychometric evaluation, the sample size is planned to be at least 10 times the number of items, and participants will be asked to complete the SVQ, as well as the Dizziness Handicap Inventory (DHI), Vertigo Symptom Scale (VSS), and Visual Analog Scale (VAS). To evaluate test-retest reliability, a subgroup of participants will be re-administered the SVQ after 7 days. No invasive procedures will be performed on participants during the research; only survey forms will be used. Written informed consent will be obtained from all participants, and data will be coded and analyzed in accordance with confidentiality principles. It is expected that the findings of this study will contribute to the literature by establishing a valid and reliable measurement tool in Turkish for the evaluation of situational dizziness symptoms and will support clinical evaluation processes.
