Clinical trials

Dysmenorrhoea is a condition that negatively affects the quality of life in women of many age groups. In girls with dysmenorrhoea in adolescence, there is an effect on school performance, self-confidence-depression problems and a decrease in quality of life due to pain. In order to eliminate these negative effects, they should receive a good treatment. Medical treatment usually tries to minimise and balance this situation. Considering the fact that families do not want to use drugs such as oral contraceptives in their children at this age and the risks of oral contraceptives, parents are in different searches. Considering that the approach to pain should always be from a holistic perspective, yoga and cognitive exercise therapy approaches are both biopsychosocial treatment methods within the scope of mind-body integrity. Yoga and cognitive exercise therapy approach is thought to reduce symptoms, improve physical functions and quality of life in adolescent girls. With these positive effects, school absenteeism decreases, depression and self-confidence improve. Health costs will also be reduced to some extent.

This study aims to investigate the effects of an 8-week FIFA 11+ exercise program on wellness, rating of perceived exertion (RPE), dynamic balance, and single-leg functional performance in young female volleyball players, as well as to examine the relationships among these variables. The study will also evaluate the program's effects on injury incidence and fear of reinjury. The study is original in applying the FIFA 11+, a well-established injury prevention program, to volleyball and evaluating its effects together with training-load parameters through a multidimensional approach. It is expected to contribute to the literature by proposing a comprehensive model for monitoring athletic performance and injury risk in young female volleyball players.

This study evaluates whether a risk-based perioperative pressure injury prevention bundle reduces the development of pressure injuries in patients undergoing elective surgery lasting 3 hours or longer. Pressure injuries that develop during and after surgery are a common patient safety problem, especially in older adults and in longer procedures. In this randomized controlled trial, patients will be assigned by chance to either an intervention group or a control group. In the intervention group, each patient's pressure injury risk will be assessed before surgery using the Braden Scale together with additional perioperative risk factors, and patients will then receive one of three prevention bundles matched to their risk level (low, moderate, or high). The high-risk bundle includes prophylactic silicone foam dressings on the sacrum and heels, targeted positioning, and pressure-redistributing support surfaces. The control group will receive standard perioperative care without risk-based bundling, although Braden Scale assessment will still be performed. Skin assessments will be conducted at four time points: before surgery, in the post-anesthesia care unit, at 2-4 hours after surgery, and at 24 hours after surgery. The main outcome is whether patients develop early signs of pressure injury, including non-blanchable erythema, within the first 24 postoperative hours. The study hypothesizes that patients receiving the risk-based prevention bundle will have a lower incidence of postoperative pressure injury and non-blanchable erythema compared with patients receiving standard care.

The aim of this study is to examine the validity and reliability of the Turkish version of the Heat Sensitivity Scale in individuals with Parkinson's disease. This cross-sectional methodological study will evaluate the psychometric properties of the scale, including internal consistency, test-retest reliability, and construct validity, in order to provide a valid and reliable tool for assessing temperature sensitivity in Turkish-speaking individuals with Parkinson's disease.

This cross-sectional descriptive study aims to identify the demographic, occupational, organisational and individual psychological factors that predict burnout among physiotherapists working in active clinical practice in Turkey. Using a four-block hierarchical multiple regression approach, the relative contribution of workload and role factors, organisational factors, psychological resilience, self-efficacy and Type A behaviour pattern to the three dimensions of burnout (emotional exhaustion, depersonalisation and personal accomplishment) will be quantified. Turnover intention is examined as a secondary dependent variable. Data are collected through an anonymous online survey distributed nationwide.

This cross-sectional, correlational study aims to determine the predictors of illness perception and treatment expectations in adults with chronic lateral elbow pain. Sociodemographic characteristics, clinical findings (pain intensity, pain duration, elbow-specific function) and psychosocial variables (pain self-efficacy, fear-avoidance beliefs, pain catastrophizing) will be examined as candidate predictors of two patient-centred constructs: illness perception, measured with the Brief Illness Perception Questionnaire, and treatment expectation, measured with the Treatment Expectation Questionnaire. Data will be analysed using hierarchical multiple linear regression in three predictor blocks. The study is reported according to the STROBE statement.

This study aims to evaluate the validity and reliability of the Turkish version of the Cognitive Self-Efficacy Questionnaire in individuals with Parkinson's disease.

The aim of this study is to examine the associations between motor imagery capacity, body awareness (interoceptive awareness), kinesiophobia, physical activity level, and symptom severity in individuals with Parkinson's disease. In addition, the study aims to evaluate the relationships between these variables and physical frailty. This cross-sectional observational study will provide insight into the biopsychosocial factors associated with frailty in Parkinson's disease.

The aim of this study is to evaluate the associations of self-compassion and self-efficacy levels with symptom severity, functional status, and quality of life in individuals with Parkinson's disease.

Massive rotator cuff tears are associated with significant pain, functional limitations, and prolonged rehabilitation following surgical repair. In the early postoperative phase, rehabilitation protocols are often limited due to surgical protection requirements, which may delay the restoration of motor control and shoulder function. Graded motor imagery (GMI), a movement representation technique that includes laterality recognition, motor imagery, and mirror therapy, has been shown to modulate cortical processing and improve pain and motor function in various musculoskeletal and neurological conditions. However, its potential role in early postoperative shoulder rehabilitation has not been adequately investigated.

The purpose of this study is to compare the effects of an 8-week supervised downhill walking training program, prescribed based on the 6-minute walk test, on functional capacity, peripheral muscle strength, and cardiovascular responses in individuals with type 2 diabetes mellitus, as compared to a level walking training program. Participants who agree to take part in the study will be randomly assigned to either the downhill or the level-ground walking group. Both groups will undergo a 6-minute walk test (6MWT) at the beginning of the study, and participants will then undergo an 8-week walking training program-conducted twice a week on a treadmill under the supervision of a physical therapist-in which their walking speed is determined based on their average speed during the 6MWT and gradually increased, with the duration of the sessions also being extended. Participants will do the following: * They will participate in walking training sessions at a center twice a week for 8 weeks, under the supervision of a physical therapist. * Once a week for 8 weeks, they will walk the same distance they walked with their supervisor that week as a homework assignment. * They will come to the facility where they conducted their exercise sessions for evaluations at the beginning of the program and after the 8th week.

This randomized controlled study aims to investigate the effects of an electrodermal activity (EDA)-based adaptive support system on performance during virtual reality (VR)-based advanced life support (ALS) training. Participants' stress levels will be continuously monitored through EDA during the simulation. When stress exceeds a predefined threshold, the adaptive system will automatically activate a support mode that provides additional guidance and time. The performance outcomes of participants receiving adaptive support will be compared with those receiving standard VR training. The study will also examine the role of presence, anxiety, social anxiety, and personality traits in the relationship between stress and performance.

Patient-Reported Outcome Measures (PROMs) have gained increasing importance in scoliosis research in recent years. Although widely used instruments such as the Scoliosis Research Society-22 (SRS-22) include domains related to body image, their primary purpose is to assess overall health-related quality of life and functional outcomes. In contrast, the Staffordshire Questionnaire for Adolescent Idiopathic Scoliosis (SQAIS) was specifically developed to provide a more detailed and patient-centered evaluation of body image and perceived deformity in individuals with adolescent idiopathic scoliosis (AIS). However, a Turkish version of the questionnaire with established validity and reliability is not currently available. Therefore, the aim of the planned master's thesis is to conduct the cultural adaptation of the Staffordshire Questionnaire for Adolescent Idiopathic Scoliosis into Turkish and to evaluate its psychometric properties in adolescents with AIS. The study will involve a systematic process of linguistic translation and cross-cultural adaptation. Subsequently, the validity and reliability of the Turkish version will be assessed through analyses of internal consistency, test-retest reliability, construct validity, and criterion validity. The findings of this study are expected to provide a valid and reliable instrument for assessing body image and deformity perception among Turkish adolescents with idiopathic scoliosis, thereby contributing an important patient-centered outcome measure to both clinical practice and research.

This prospective randomized clinical trial aims to compare quadriceps tendon and peroneus longus tendon autografts in anterior cruciate ligament reconstruction. Patients with anterior cruciate ligament injury undergoing primary reconstruction surgery will be randomly assigned to one of the two graft groups. Clinical examination findings, return-to-sport outcomes, ankle muscle strength, ankle-related functional scores, and gait analysis parameters will be evaluated at 6 months and 12 months postoperatively. The study aims to investigate both knee-related functional outcomes and donor site morbidity associated with graft harvesting techniques.

This randomized controlled trial aims to investigate the effects of a 24-week home-based progressive resistance exercise program combined with tirzepatide treatment on skeletal muscle mass, muscle quality, and functional capacity in overweight and obese individuals. A total of 108 participants initiating tirzepatide therapy will be randomized to either exercise plus pharmacotherapy or pharmacotherapy alone. The primary outcome is change in thigh muscle thickness and echo intensity assessed by ultrasonography.

This study investigates the acute effects of smartphone-delivered local vibration on hand sensorimotor performance in healthy young adults. Using a custom-developed iPhone application, three vibration frequencies (80 Hz, 150 Hz, and 220 Hz) are applied to the dominant hand in a randomized crossover design with a minimum 48-hour washout between sessions. The primary aim is to evaluate frequency-dependent dose-response effects on hand grip strength. Secondary aims include assessment of two-point discrimination (tactile spatial acuity), pressure pain threshold, and hand reaction time before and immediately after each vibration condition. The study seeks to generate evidence on optimal application parameters for smartphone vibration as an accessible and portable local vibration source in clinical and educational settings.

This study aims to identify injury risk factors using a clinical/functional test battery in university basketball and volleyball athletes, to develop individualized exercise prescriptions for athletes scoring below established cut-off values on each test, and to evaluate the effects of an 8-week intervention program on test parameters. As a secondary aim, all participants will be monitored prospectively over a 6-month season to assess the incidence of injuries and health problems, and to evaluate the contribution of the individualized program to injury-related health outcomes. The study consists of four phases: (1) baseline cross-sectional assessment (T0), (2) 8-week individualized exercise intervention for athletes below cut-off thresholds, (3) post-intervention reassessment (T1), and (4) 6-month prospective injury surveillance (T2).

The goal of this clinical trial is to learn if an exercise protocol can improve temporomandibular pain, jaw function and muscle mechanical properties in individuals with Temporomandibular Disorders (TMD). This study focuses on patients who are already receiving occlusal splint therapy. The main question it aims to answer is: How does the addition of an exercise protocol to occlusal splint therapy affect temporomandibular pain, jaw function and muscle mechanical properties of the masticatory and neck muscles? Researchers will compare the group receiving both occlusal splint therapy and the exercise protocol to a group only occlusal splint therapy to see if the combined approach is more effective. Participants will: * Undergo an initial assessment of the Jaw Functional Limitation Scale-20 (JLFS-20), Craniofacial Pain and Disability Inventory (CF-PDI), Graded Chronic Pain Scale Version 2.0 (GCPS-2.0), jaw range of motion, pain pressure threshold and muscle mechanical properties. * Receive occlusal splint therapy as a part of their treatment. * Perform a structured exercise protocol (only 1 group) * Attend follow up sessions at the 4th week to monitor changes in all initial assessment parameters.

Frozen shoulder (adhesive capsulitis) is a condition characterized by shoulder pain and restricted range of motion, significantly impairing daily living activities. In cases that do not respond to conservative treatment, arthroscopic capsular release is an effective surgical treatment option. The 360° capsular release technique, performed by some surgeons, involves release of the inferior capsule and therefore carries a potential risk of nerve injury due to the anatomical proximity of neurovascular structures such as the axillary nerve. In addition, surgical manipulations performed around the coracoid process may exert mechanical or compressive effects on the musculocutaneous nerve and its sensory continuation, the lateral antebrachial cutaneous nerve, due to their close relationship with the lateral cord of the brachial plexus. The aim of this prospective, single-center observational clinical study is to objectively evaluate the morphological and functional effects of inferior capsular release and coracoid region dissection performed during arthroscopic 360° capsular release surgery on the axillary and musculocutaneous nerves, using electromyography (EMG) and nerve conduction studies (NCS) in patients with frozen shoulder. Patients aged 21-70 years with a diagnosis of frozen shoulder who have not responded to conservative treatments and are scheduled for arthroscopic capsular release will be included in the study. EMG and NCS assessments will be performed at the preoperative baseline, and at 12 weeks postoperatively. For the axillary nerve, the deltoid and teres minor muscles will be evaluated; for the musculocutaneous nerve, the biceps brachii and brachialis muscles will be assessed. Additionally, sensory conduction of the lateral antebrachial cutaneous nerve will be examined. Along with electrophysiological findings, shoulder range of motion (ROM), pain (VAS), muscle strength (MRC), and functional scores will also be recorded. This study is expected to provide objective evidence regarding the effects of arthroscopic capsular release surgery on peripheral nerve function, thereby contributing new data on the safety of the surgical technique and enriching the currently limited literature on electromyographic evaluation in frozen shoulder surgery.

The postpartum period is a critical time marked by significant physiological and psychosocial changes that can affect sleep, emotional well-being, and breastfeeding behaviors. Previous studies indicate that mode of delivery and sleep quality are closely associated with breastfeeding outcomes, with cesarean birth often linked to poorer sleep and lower breastfeeding success. Evidence also suggests that postpartum sleep disturbances are related to reduced breastfeeding self-efficacy, lower motivation, fatigue, depressive symptoms, and shorter breastfeeding duration. However, the literature lacks studies that evaluate insomnia severity, breastfeeding motivation, and breastfeeding success simultaneously-particularly during the first 48 hours after birth. This analytical study aims to assess insomnia severity, breastfeeding motivation, and breastfeeding success (LATCH) within the first 48 postpartum hours and to examine the relationships among these variables. Findings are expected to support early postpartum clinical interventions to improve maternal and infant health outcomes.

This randomized controlled trial aims to examine the effects of Gentle Human Touch applied by fathers during the first hours of life on sucking performance, comfort level, and blood glucose values in newborns at risk for hypoglycemia. Eligible newborns will be randomly assigned to intervention and control groups. After the newborn is taken to the baby care room and routine care procedures are completed, comfort level will be assessed by the primary nurse and an independent second observer using the Neonatal Comfort and Behavior Scale (NCBS). In the intervention group, the first Gentle Human Touch application will begin after routine care and the initial comfort assessment are completed. Sucking performance will be assessed during the first breastfeeding session by the primary nurse and an independent observer using the LATCH Breastfeeding Assessment Tool. In the intervention group, fathers will administer 15-minute Gentle Human Touch sessions every hour for six hours according to a structured protocol. In the control group, routine care will be provided without any additional touch. In both the intervention and control groups, blood glucose levels will be measured at the 2nd hour according to clinical protocols. At the 6th hour, the newborn's comfort level (NCBS), sucking performance (LATCH), and blood glucose level will be reassessed and recorded. This study aims to determine whether early paternal touch supports glucose stability, improves sucking performance, and enhances comfort in newborns at risk for hypoglycemia, and to contribute to the development of family-centered, non-invasive care practices in neonatal settings.

This cross-sectional observational study aims to examine the relationship between self-compassion, self-efficacy, postural awareness, pain, quality of life, and health-promoting lifestyle behaviors in adults aged 65 years and older. Data will be collected using validated self-report questionnaires administered online. The findings are expected to contribute to a better understanding of psychological factors associated with physical and behavioral health outcomes in older adults.

Infertility affects approximately one in six individuals worldwide and is associated with significant psychological distress, particularly among women undergoing treatment. Increased anxiety levels are strongly linked to reduced quality of life during the infertility process. With the growing integration of artificial intelligence (AI) into healthcare, AI-based tools are increasingly used in infertility care to support decision-making and patient engagement. While many patients are familiar with AI technologies, individual attitudes toward AI may influence their acceptance and potential psychosocial benefits. This study aims to examine the relationship between attitudes toward artificial intelligence, anxiety levels, and quality of life among women undergoing infertility treatment.

The aim of this study is to evaluate the effect of two pacifier-use strategies-routine 5-minute pacifier use prior to each feeding versus random 30-minute pacifier use at any time of day, independent of feeding-on feeding maturity in preterm infants. The hypotheses of the study are as follows: H1: The routine use of a pacifier prior to feeding has a positive effect on feeding maturity in preterm infants. H2: The routine use of a pacifier prior to feeding has a positive effect on discharge weight in preterm infants. H3: The routine use of a pacifier prior to feeding has a positive effect on the length of hospital stay in preterm infants. H4: The routine use of a pacifier prior to feeding has a positive effect on the gestational age at discharge in preterm infants.

This study will be conducted in the coronary intensive care unit of Dr. Siyami Ersek Chest, Heart and Vascular Surgery Training and Research Hospital. It aims to investigate the effect of hand fan therapy on ticagrelor-associated dyspnea in patients receiving ticagrelor.
