Lower Extremity Assessment Protocol (LEAP)

The purpose of this study is to learn more about leg function, physical performance, and quality of life after knee injury. We know that leg function changes after an injury occurs and that this changes the way people move and feel about their overall health. The goal of this study is to determine whether the quality of leg function and physical performance may help predict how well someone will do after a knee injury or surgery. Overall, we hope to get information that may improve health care and quality of life for people with knee injuries.

We expect that you will be in this research study for at least 1 session, lasting about 60 minutes (~15 minutes remotely, ~ 45 minutes in person). However, you will have the option to complete as many as 8 sessions if you begin the study with a history of knee injury, or as many as 9 sessions if you begin the study with no history of knee injury, but later become injured. The minimum duration of study participation is 1 day and the maximum duration of study participation is 2 years.

You will be asked to complete several online questionnaires during each completed study session that ask questions related to how you feel about your knee function, psychological well-being, and overall health. In addition, you will be asked to perform several tests that assess your thigh strength and physical performance at the UCF Cognition, Neuroplasticity, & Sarcopenia (CNS) Laboratory.

Inclusion Qualifications:

  • Age 12-45 years
  • History of knee injury (e.g., ACL tear, meniscus tear, patellofemoral pain, osteoarthritis) or surgery (e.g., ACL reconstruction, meniscectomy or repair, total knee arthroplasty) within the last 2 years
