Clinical trials

This study will be conducted to evaluate the effect of the Traction, Pressure, and Rapid Muscle Release (TPR) technique, an innovative method used during intramuscular vitamin B12 (cyanocobalamin) injections, on patients' pain and satisfaction levels compared with the conventional injection method.

The aim of this cross-sectional study is to evaluate muscle strength in female patients with carpal tunnel syndrome (CTS) who have only sensory involvement detected on electromyography. Muscle strength will be assessed using the "Lafayette Manual Muscle Tester®". The main questions of the study are: 1. Is there a difference in muscle strength between healthy individuals and female patients with carpal tunnel syndrome? 2. Is there a difference in muscle strength between female patients with carpal tunnel syndrome who have only sensory involvement and those who have both sensory and motor involvement? 3. Are there differences in the strength of thumb palmar abduction and adduction, radial adduction and abduction, thumb flexion, extension and opposition, and flexion of the proximal interphalangeal (PIP) and distal interphalangeal (DIP) joints of the fingers between these groups? The investigators will measure the muscle strength associated with these movements using the "Lafayette Manual Muscle Tester®" in order to objectively evaluate motor involvement in female patients with carpal tunnel syndrome and to compare muscle strength between healthy individuals and patients with different degrees of electrophysiological involvement.

The purpose of this prospective, randomized, single-blind clinical study is to evaluate and compare the effectiveness of distraction using virtual reality (VR) glasses and deep-pressure stimulation using weighted blankets on dental anxiety, cooperation, and pain perception in school-aged children. The study focuses on children aged 5-9 years with high dental anxiety (CFSS-DS score ≥39) who require dental procedures involving local anesthesia, such as Class II restorations, pulpotomy, or extractions. Participants will be randomly assigned to four groups: a control group receiving standard behavior guidance, a VR group, a weighted blanket group, and a combined group using both VR and weighted blankets. The study aims to determine the effects of these non-pharmacological, non-invasive, sensory-based interventions on children's clinical experience and physiological parameters.

This study aims to compare the effects of the Hunsuck and Posnick modifications of medial mandibular osteotomy on postoperative skeletal stability and relapse in patients undergoing orthognathic surgery. The study will evaluate whether the choice of medial osteotomy technique influences postoperative mandibular relapse.

This controlled cross-sectional observational study aims to compare sleep quality between adolescents with idiopathic scoliosis and age- and sex-similar healthy controls. Participants aged 10-18 years will complete online questionnaires assessing demographic characteristics and sleep quality. Adolescents with idiopathic scoliosis will also be evaluated for scoliosis-specific quality of life, body image, Cobb angle, curve type, pain, brace use, and daily brace-wearing duration. The study will additionally investigate factors associated with sleep quality in the scoliosis group. The planned enrollment is 100 participants, including 50 adolescents with idiopathic scoliosis and 50 healthy controls.

Adolescent idiopathic scoliosis (AIS) is a three-dimensional spinal deformity associated with impaired respiratory muscle strength, balance, postural control, body image, and health-related quality of life. Core stabilization exercises are widely used in the conservative management of AIS. Horse riding simulator training reproduces the multidirectional rhythmic movements of horseback riding while eliminating the potential risks associated with conventional hippotherapy and may provide additional benefits for postural control and trunk muscle activation. The aim of this randomized controlled trial is to investigate the effects of adding horse riding simulator training to a core stabilization exercise program on respiratory muscle strength, balance, health-related quality of life, and perceived cosmetic deformity in adolescents with idiopathic scoliosis. Participants will be randomly assigned to either an experimental group receiving horse riding simulator training combined with core stabilization exercises or a control group receiving core stabilization exercises alone. Outcomes will be assessed before and after the 12-week intervention.

This study aims to evaluate postoperative condylar remodeling in patients undergoing bimaxillary orthognathic surgery by comparing two different proximal segment positioning techniques used during mandibular osteotomy. Condylar remodeling will be assessed using preoperative, immediate postoperative, and 6-month postoperative computed tomography (CT) scans together with clinical findings.

Coronary artery bypass grafting (CABG) may be associated with prolonged recovery, particularly in high-risk patients. Although preoperative rehabilitation has shown promising results, evidence remains limited because of heterogeneous intervention protocols and variations in postoperative care. This study aims to investigate the effects of a structured inpatient physiotherapy program initiated at least two days before surgery and continued postoperatively, compared with the same structured physiotherapy program provided only during the postoperative period, in high-risk CABG patients. The primary outcome is hospital length of stay. Secondary outcomes include intensive care unit length of stay, C-reactive protein, neutrophil-to-lymphocyte ratio, hemoglobin, dyspnea, and fatigue.

This study aims to compare the effects of virtual reality-based aerobic exercise and treadmill-based aerobic exercise on functional capacity, pulmonary function, and clinical outcomes in children with asthma. Participants aged 10-17 years with physician-diagnosed asthma will be randomly assigned to either a virtual reality-based exercise group or a treadmill exercise group. Both groups will undergo supervised exercise training sessions twice a week for 8 weeks. Primary outcome will be the 6-Minute Walk Test. Secondary outcomes include pulmonary function, respiratory muscle strength, asthma control, quality of life, and exercise adherence.

This study aims to identify which of the following factors-physical activity level, nutritional status, or pregnancy-related anxiety-has the strongest influence on excessive gestational weight gain. Pregnant women in their third trimester who are being followed at Gebze Fatih State Hospital and meet the inclusion criteria will be referred to the Exercise Therapy Laboratory of the Department of Physiotherapy and Rehabilitation, Faculty of Health Sciences, Bezmialem Vakıf University. After being informed about the study and providing written informed consent, participants will undergo a face-to-face assessment. Data will be collected prospectively using a demographic information form, the Pregnancy Physical Activity Questionnaire (PPAQ), a nutritional status assessment form, and a pregnancy-related anxiety questionnaire.

The menopausal transition is associated with substantial hormonal alterations that may adversely affect lower urinary tract function, bowel function, and sexual health. Although these symptoms are common, few studies have comprehensively evaluated all three pelvic floor compartments across different menopausal stages. The aim of this study is to compare lower urinary tract symptoms, bowel symptoms, and female sexual function among women in the perimenopausal, early postmenopausal, and late postmenopausal stages. In addition, the relationship between menopausal stage and symptom severity will be investigated.

This study aims to investigate whether co-activation of the pelvic floor and core muscles improves treatment outcomes in individuals with urinary incontinence. Participants diagnosed with stress, or mixed urinary incontinence will undergo a 12-week pelvic floor physiotherapy program, with or without additional core muscle co-activation exercises. Changes in urinary incontinence severity, pelvic floor muscle function, core muscle activation, and quality of life will be evaluated.

This prospective, randomized, single-blind, controlled clinical trial aims to evaluate and compare the efficacy of cognitive-based balance rehabilitation delivered via immersive Virtual Reality (VR) versus traditional Dual-Task Training (DTT) on balance, gait, cognitive functions, and quality of life in patients with Parkinson's Disease (PD). Postural instability and cognitive decline are hallmark features of progressive PD that significantly elevate fall risks and compromise daily independence, yet conventional pharmacological therapies offer limited effectiveness in restoring complex postural control. Given that motor and cognitive processes are intrinsically linked, this study addresses a critical gap in neurorehabilitation by investigating two contemporary modalities designed to challenge these systems simultaneously. A total of 34 participants diagnosed with PD (aged 40-80 years, Hoehn and Yahr stages I-III) will be randomly allocated to either the Dual-Task Group (DTG), receiving structured therapeutic exercises integrated with sequential cognitive tasks, or the Virtual Reality Group (VRG), engaging in an immersive balance program utilizing the Oculus Quest 2® headset with the FIT-XR application. Both groups will undergo an identical intervention protocol consisting of 45-minute supervised sessions, conducted twice weekly for 8 consecutive weeks during their pharmacological "on" phase. Standardized assessments will be performed by a blinded clinician at baseline and post-intervention (Week 8). The primary outcome measures will be dynamic balance and gait assessed through the Mini-Balance Evaluations Systems Test (Mini-BESTest) alongside global cognitive performance measured via the Montreal Cognitive Assessment (MoCA). Secondary outcomes will encompass objective posturographic indices using the Biodex Balance System, motor severity via the Unified Parkinson's Disease Rating Scale (UPDRS-III), freezing of gait, health-related quality of life, global perceived improvement, and potential cyber-sickness symptoms monitored through the Virtual Reality Sickness Questionnaire (VRSQ) to comprehensively determine the safety and comparative therapeutic value of these interventions.

This prospective, randomized controlled trial will enroll 40 individuals with idiopathic PD (Hoehn \& Yahr stages 1-3, MoCA ≥21). Participants will be randomly assigned in a 1:1 ratio to either a telerehabilitation LSVT BIG group or a face-to-face LSVT BIG group, with randomization stratified by Hoehn \& Yahr stage using a computer-based block randomization system. Both groups will receive the standard LSVT BIG® protocol consisting of 16 sessions over four weeks (4 days/week, 1 hour/session). Treatment content will include maximal daily exercises, functional component tasks, "big" gait training, and individually tailored hierarchy tasks. The telerehabilitation group will receive all sessions via synchronous video conferencing under physiotherapist supervision, while the face-to-face group will receive sessions in a clinical setting. Both groups will be assigned home exercise programs in accordance with the LSVT BIG® protocol, and treatment adherence will be monitored throughout the study. Outcomes will be assessed at baseline, after 4 weeks of treatment, and at 6-month follow-up. Primary outcomes include postural stability and fall risk assessed with the Biodex Balance System (anterior-posterior stability index, mediolateral stability index, general stability index, fall risk index, limits of stability) and motor and non-motor symptom severity assessed with the MDS-UPDRS (Parts I, II, and III). Secondary outcomes include dynamic balance (Mini-BESTest), functional mobility (Timed Up and Go Test, 10-Meter Walk Test), quality of life (PDQ-39), depression (Beck Depression Inventory), sleep quality (Parkinson's Disease Sleep Scale), fatigue (Parkinson Fatigue Scale), cognitive function (MoCA), and treatment satisfaction (Global Rating of Change Scale).

This prospective split-mouth clinical study aims to compare the clinical performance of a bioactive bulk-fill composite with a conventional microhybrid composite in Class II posterior restorations. In each participant, two comparable Class II cavities will be treated using different restorative approaches. In the experimental condition, a bioactive bulk-fill composite (Activa BioACTIVE Bulk Flow) will be placed at the gingival base and covered with a microhybrid composite (Filtek Z250). In the control condition, restorations will be completed entirely with the microhybrid composite (Filtek Z250). Clinical performance will be evaluated according to FDI World Dental Federation criteria at baseline, 6 months, and 12 months. Primary outcomes include marginal adaptation, retention, and overall clinical success of the restorations. Secondary outcomes include surface properties and marginal staining. The split-mouth design allows direct intra-individual comparison, thereby minimizing inter-individual variability and increasing the reliability of the findings. The results of this study are expected to provide evidence on the effectiveness of bioactive bulk-fill composites in improving the clinical performance of posterior restorations.

Eczematous otitis externa is a common inflammatory condition of the external auditory canal characterized by itching, discomfort, discharge, and pain. Topical corticosteroids are widely used for treatment; however, alternative therapies with fewer side effects are of increasing interest. This study aims to compare the efficacy of Nigella sativa (black seed) oil and mometasone furoate ear drops in the treatment of eczematous otitis externa. Nigella sativa is a natural product with known anti-inflammatory and antimicrobial properties. In this randomized, controlled clinical trial, adult patients with eczematous otitis externa will be assigned to receive either Nigella sativa oil or mometasone furoate ear drops for 10 days. Clinical symptoms and inflammatory findings will be evaluated at baseline and after treatment. The objective of this study is to determine whether Nigella sativa oil is an effective and safe alternative to topical corticosteroid therapy.

Accurate evaluation of dental pulp health is essential to avoid unnecessary endodontic treatments. In routine dental practice, pulp sensibility is commonly assessed using electric pulp testing and thermal (cold) testing. However, these tests depend on patient perception and may be influenced by various factors such as systemic diseases, nerve damage, anxiety, trauma, or medication use. Diabetic polyneuropathy is a common complication of diabetes mellitus and may alter peripheral nerve function, potentially affecting dental pulp sensibility test responses. This clinical study aims to evaluate how the severity of diabetic polyneuropathy influences dental pulp sensibility responses and masseter inhibitory reflex (MIR) parameters. The MIR is an objective neurophysiological reflex that allows quantitative assessment of trigeminal nerve function. In this study, individuals with mild diabetic polyneuropathy, severe diabetic polyneuropathy, and healthy controls will be evaluated. All participants will undergo electric pulp testing, cold testing, and MIR measurements using standardized protocols. The primary hypothesis of this study is that increasing severity of diabetic polyneuropathy leads to reduced dental pulp sensibility responses and altered MIR parameters compared to healthy individuals. It is further hypothesized that conventional pulp sensibility tests may produce false-negative results in patients with advanced neuropathy. The findings of this study are expected to contribute to more accurate endodontic diagnosis and improved understanding of orofacial neurophysiological changes in diabetic patients.

This randomized controlled pilot study aims to compare the effects of virtual reality-based preoperative education and routine preoperative education on surgical anxiety in patients undergoing lumbar disc surgery. In addition to evaluating psychological outcomes, the study will also compare psychometric anxiety assessments with a biological stress marker, salivary cortisol, to examine the relationship between subjective and physiological stress responses. Preoperative anxiety is common among surgical patients and may negatively influence both emotional well-being and physiological stress regulation. Virtual reality-based education may provide a more immersive and engaging learning experience compared to routine education, potentially reducing anxiety levels. Participants will be randomly assigned to either a virtual reality-based education group or a routine preoperative education group. Surgical anxiety will be assessed using validated psychometric measurement tools, and physiological stress response will be evaluated through salivary cortisol analysis. The study will further explore the concordance between psychometric findings and biological stress indicators. The results may contribute to the development of innovative, evidence-based nursing interventions and provide insight into the relationship between psychological and biological indicators of preoperative anxiety.

This prospective observational case-control study aims to evaluate the association between perceived stress levels in children and their parents and the presence of clinically diagnosed bruxism in children aged 8-11 years. Children with bruxism and age-matched controls will be recruited from the Department of Pediatric Dentistry. Child perceived stress, parental perceived stress, parenting-related stress, and parental awareness of child stress/anxiety will be assessed using validated questionnaires. Associations between stress-related measures and bruxism status will be analyzed.

Diabetes is a chronic metabolic disease that is becoming a growing public health problem worldwide, affecting people's lives in many ways. It is characterized by impaired carbohydrate, lipid, and protein metabolism associated with insufficient insulin secretion and/or reduced sensitivity to the metabolic effects of insulin.Along with diabetes, many complications may develop in affected individuals. Cognitive impairments are now also considered an important and common complication of diabetes.The aim of this study is to investigate the effects of cognitive function levels on functional capacity, balance, fear of falling, and quality of life in individuals with type 2 diabetes.In this context, participants' cognitive function levels will be assessed using the Mini-Mental State Examination and the Stroop Test. Functional capacity will be evaluated using the 6-Minute Walk Test. Balance performance will be assessed using the Biodex Balance System and the Four Square Step Test. Lower extremity muscle strength will be measured using a digital hand-held dynamometer and the 30-Second Sit-to-Stand Test. Fear of falling will be evaluated using the Falls Efficacy Scale-International (FES-I), the Functional Reach Test, and the Timed Up and Go (TUG) Test. Participants' quality of life will be assessed using the WHOQOL-BREF quality of life questionnaire.

The study aims to overview patients registered to Bezmialem Vakıf University Hospital Intensive Care Unit after successive cardiac arrest resuscitation from October 2010 to September 2025. The goal is to determine length of stay in reanimation, neurological clinical outcome and costs of these patients at discharge from the department. All these data is intended to be evaluated by artificial intelligence to evaluate a predictive model.

Hallux valgus is a progressive foot deformity characterized by lateral deviation of the great toe and medial displacement of the first metatarsal head. While pain is a common symptom among individuals with HV, alterations in plantar pressure distribution and impaired balance are also frequently observed. These symptoms and biomechanical changes can negatively impact posture and gait mechanics. The aim of this study is to investigate the acute effects of prolonged walking on pain, balance, posture, and gait in individuals with hallux valgus deformity.

Thoracic surgery is the primary intervention used in the treatment of diseases affecting the lungs, pleura, chest wall, and mediastinum. Postoperative changes occur in both lung functions and clinical symptoms due to the procedure itself and patient-related factors. After thoracic surgery, patients often experience reduced exercise tolerance and impaired respiratory functions, negatively affecting their participation in daily activities, functional levels, and quality of life. In open thoracotomies, the incision site, severed muscles, and the size of the incision can impact upper extremity and trunk functions. The aim of this study is to investigate the effects of physiotherapy applied through digital methods on respiratory functions, respiratory muscle strength, functional capacity, upper extremity muscle strength, and quality of life in patients who have undergone thoracic surgery.

This study aims to better understand how pregnancy affects the health of the gums and tissues that support the teeth. During pregnancy, hormone levels (like estrogen and progesterone) increase significantly. These hormonal changes can cause many changes in the body, including in the mouth. Some pregnant women may notice that their gums become swollen, red, or bleed more easily - this is called pregnancy gingivitis. It happens more often during the second and third trimesters and usually improves after birth. Even if a pregnant person has good oral hygiene, hormonal changes may still make the gums more sensitive to plaque and bacteria. Scientists believe that these changes in gum health are linked to how the body responds to hormones, bacteria in the mouth, and changes in the immune system. To explore this further, saliva samples will be collected from: * Pregnant women during their 1st, 2nd, and 3rd trimesters * The same women again 6-8 weeks after giving birth * A group of non-pregnant, healthy women as a comparison group The investigators will use a scientific method called untargeted metabolomics to study these saliva samples. This method helps looking at small substances (called metabolites) in saliva to see if there are any patterns related to pregnancy and gum health. The goal is to identify biological changes that happen during pregnancy and understand how they might affect the gums. This research will help improve early detection and prevention of gum problems during pregnancy in the future.

The aim of this study is to evaluate the effect of anti-gravity treadmill training on symptoms and functions in patients with meniscus tears.
