Are you an adult under the age of 59 years? Do you sit too much and want to learn more about how sitting impacts the stiffness of your blood vessels? If so, you may be able to participate in a study to see how the position of your legs affects your arteries after sitting for a long time. Compensation provided.

The purpose of this study is to examine associations between an athlete's concussion history, perceived social support, perceived stress, and kinesiophobia (fear of movement) symptoms. A better understanding of these associations may help clinicians and researchers understand the importance of implementing mental health care into the rehabilitation process of recovering from a concussion.

Have you recently had an anterior cruciate ligament injury and will be undergoing anterior cruciate ligament reconstruction surgery? If so, you may be able to participate in a study comparing the effects on pain relief and arthritis prevention of metformin or placebo. Compensation provided.

The purpose of this study is to characterize sleep and to examine the associations between sleep and psychological outcomes after ACL reconstruction

The purpose of this study is to investigate the intricate relationship between core stability, biomechanics, and performance outcomes in females, aiming to fill the existing knowledge gap by assessing the association of core stability tests with both ACL injury risk biomechanics and overall athletic performance, while also examining the impact of core stability on performance while mentally multitasking.

Are you perimenopausal? Are you interested in learning more about your metabolism, body composition, and exercise during the menopause transition? If so, you may be able to participate in a research study to understand the impact of muscle and exercise across perimenopause!

In this study, we want to find out more about the relationship between jumping and running tasks and a virtual reality task. We also want to find out how a recent concussion (within the last 9 months) may impact completing these tasks.

This study is comparing the effect of video game therapy versus standard physical therapy on outcomes for knee osteoarthritis (OA) patients. Patients with knee OA will be placed in either 8 weeks of standard physical therapy or 8 weeks of physical therapy using a video game at a UNC PT clinic. The cost of PT will be covered by the study.

The purpose of this study is to learn more about the number of female collegiate athletes who fall in the "at-risk"category for developing low energy availability. Low energy availability can cause an increased risk of developing a musculoskeletal injury. If we can learn how common the condition is, then we can work to develop better strategies for screening purposes.

We are studying how people's daily physical activity and alcohol use behaviors are related to their risk for obesity and inflammation. We are collecting this information to learn more about disease risk and to inform future research studies and interventions.
