About

The goal of this clinical trial is to investigate changes in cognitive and physical performance after 10 weeks of dual or single task training in anterior cruciate ligament (ACL) reconstructed individuals. The main questions it aims to answer are:

• Does cognitive performance in ACL reconstructed individuals change after multiple training sessions incorporating single versus dual-task?
• Does physical performance and intrinsic motivation for training change over the course of 10 weeks when performing single versus dual-task training sessions?
• What movement patterns do ACL reconstructed individuals show during a dual-task training in an immersive environment?

Researchers will compare a combined dual-task training (combined physical and cognitive training) to a single task training (physical and cognitive training separately) to see if there are changes on cognitive performance depending on the training type.

Participants will:

• Perform dual-task or single task training twice per week for 10 weeks
• Visit the clinic before and after the training period for tests
• Visit the movement laboratory once for analysis of movement patterns
