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.

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.

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.

Think you have good reaction time? Would you like to get involved in research? You may be able to participate in a research study for upper extremity reaction time.

In this study, we want to learn more about two strategies that interrupt sitting: walking and seated pedaling. Sitting, or sedentary behavior, is a public health crisis that increases all causes of mortality and doubles the risk of cardiovascular disease. Interrupting sitting may help reduce the cardiovascular disease risk associated with uninterrupted bouts of sitting.

We are conducting a research study to use graded exposure and mobile mindfulness meditation to address clinical outcomes in individuals 6-months to 10-years post-ACLR. This will help develop effective treatments to improve outcomes after ACLR. This study will last 5 weeks. Compensation provided.
