Selective blockade of the saphenous nerve branches is among the regional anesthesia techniques in knee surgery. In this block, analgesia is provided without motor block and is an essential advantage in terms of early mobilization in the postoperative period. Blockage of motor branches causes a delay in mobilization and increases the risk of falling. The vastus medialis and its medical femoral cutaneous branch are rich in the femoral triangle. Effective postoperative analgesia is provided by a femoral triangle (triangle) blockade. The intermediate femoral cutaneous nerve courses over the sartorius muscle. Anatomically, the femoral triangle follows a separate path. When the femoral triangle and the blockade of the intermediate femoral cutaneous nerve are combined, it is called PSKB block. Parasartorial compartment block (PSKB); is based on the blockade of the branches of the saphenous nerve, the two largest sensory nerves from the femoral nerve to the knee, and is predicted to provide effective postoperative analgesia in knee arthroplasty.
The goal of this study is to pilot test a skills-based virtual reality (VR) for acute orthopedic injury. It will measure the feasibility, signals of improvement, exploratory pain mechanisms, and user experience of an established skills-based program (RelieveVRx) for acute orthopedic injury.
The purpose of this study was to analyze if a low ankle dorsiflexion range is associate with dynamic knee valgus in youth basketball players.
Functional Hop tests and balance measurements are frequently used to decide on returning to sports after lower extremity injuries. Although the athletes show proficiency in these tests and measurements, re-injuries occur when returning to sports. The causes of these re-injuries are mostly functional deficiencies such as inadequate neuromuscular control and stability. In the competition or sports environment, especially in team games, the athlete also shows cognitive performance, such as communication with teammates and following the game, which are included in the game setup, as well as the physical performance. Performing many tasks or performances at the same time divides the focus of attention on the activities performed, and if the person cannot adequately meet the attention demands, the quality of one or more of the tasks performed will deteriorate. As the level of expertise in the sport increases, the athlete tends to manage his posture, balance and movement with automatic postural control and can focus his attention on a new task. The concept of focus of attention has been evaluated from different perspectives over time. If it is examined in terms of direction; It is divided into two as the internal focus of attention, which is used by focusing on body movements during the performance of the person, and the external focus of attention, which is used by focusing on the effect of the movement during the performance of the person. As the investigators planned in this study, a second cognitive task assigned to the participant simultaneously during his or her physical performance acts as an external focus of attention, allowing movement control during performance to be carried out by unconscious or automatic processes. The investigators's aim; It is to examine the balance and functional hop tests that the investigator will apply in athletes by combining them with a simultaneous dual cognitive task that will reflect the field conditions more realistically. In the meantime, investigators think that with the sharing of our results with the literature, it can contribute to both the decision-making processes to return to sports after injury and preventive rehabilitation programs.
Six cadaveric lower limbs will have PSI slope-reducing MOWHTO performed on and accuraccy of biplanar correction will be assessed.
The large number of studies in the recent decade dealing with knee injury prevention seems not effective enough to cause a decline in knee injury rates. Thus, it has been proposed to use non-linear mathematical models that simulate the operation of complex and dynamic systems. The present study aims to analyze the dynamic relationships of the risk factors for knee injuries through system dynamics modeling to effectively predict and prevent knee injury. The first part of this project includes a qualitative study informing the theoretical non-linear interrelationships among the risk factors. The aim is to examine the initial hypothetical model formulated in the first part of the project through statistical analysis such as factor analysis and structural equation modeling. Pre-season and in-season data from questionnaires and biomechanical measurements for risk factors will be collected from at least 100 athletes who participate in high-risk sports. The athletes will be monitored for injuries during one season, and these data will be used in the next part of the research plan. The next part of the project aims to develop a dynamic simulation model for predicting knee injuries using specific equations. The function of the simulation model will predict the propensity of knee injuries over time. The next step includes the validation and calibration of the model based on the knee injuries that occurred during the season. The validated and calibrated model will then provide implications for effective policy decisions in knee injury prevention.
The aim of this study is to compare the effects of different arm positions on muscle activity during single leg squat.
In the context of prescribed opioids, research suggests that increased exposure is associated with long-term opioid use. Orthopedic surgeries are associated with the prescribing of more opioid narcotics than any other surgical specialty, particularly for Total Knee Replacement surgery, which is associated with severe post-operative pain. The proposed project is a randomized clinical trial to explore the efficacy of our Total Knee Replacement Opioid Reduction Program (ORP) vs. Treatment As Usual (TAU) in the reduction of opioid use following total knee replacement surgery.
The present project on sport rehabilitation aims at validating a rehabilitation protocol in immersive virtual reality (IVR) for restoring motor functions following peripheral injuries of the lower limbs. Sport injuries are related to direct and indirect costs and, in many cases, cause an interruption of motor activity for prolonged periods. Sport physiotherapy aims at recovering the motor functionality in order to guarantee the fastest possible return to sport. It employs plasticity and compensatory mechanisms within the injured motor system. However, being primarily based on the execution of movements that can be largely compromised, the treatment might be intrinsically complicated. It has been suggested that the motor system can be activated by observing one's own body perform the movements, without any actual movement execution. By using multisensory integration and sense of presence in IVR, it is possible to create an illusory experience that a moving virtual body (avatar) temporarily becomes one's own moving body. Moreover, this experience activates the motor system similarly to the activation from one's own actual movements. Based on these considerations, the present study hypothesizes that observation of one's own virtual body, without any movement execution, might activate the motor system to the extent of significantly improving functional recovery. The randomized clinical trial will recruit participants that underwent knee surgery and are in the first phase of the rehabilitation period (starting within two weeks after the surgery). Together with the traditional training protocol (4-6 weeks) participants will be administered a training in IVR that will include a virtual avatar performing a series of standard lower limb rehabilitation exercises. Participants will be randomly assigned to the experimental group (avatar observed from the first-person perspective, i.e., perceived as one's own body), the active control group (avatar observed from the third-person perspective, i.e., perceived as another person's body) and the group with no intervention. Before, at midpoint and after intervention, a standard battery of tests will be administered to evaluate the state of the motor system), as well as measures of embodiment for controlling the efficacy of the virtual scenario. The hypothesis is that the experimental group will show greater improvement of the motor functionality compared to the two control groups.
