General inclusion criteria are:
- Age between 18 and 50 years
- Physically active before the injury (2x 45 minutes per week) (Booth & Lees, 2006)
- Clinically confirmed ACL rupture/reconstruction or no previous knee pathology

Exclusion Criteria

Previous knee pathology before ACL rupture;
injuries of the lower extremity; musculoskeletal diseases; cardiac, neurological or peripheral vascular diseases

Study & Design

Study Type: observational

Primary Outcome Measures

Name	Time	Method
Primary outcome angle reproduction:<br>neuromuscular activity normalized to gait activity during angular reproduction<br>- Pre-activation<br>- Start of movement to target angle<br>- Activity at target angle<br>- From the target angle to the end point of the movement. <br> <br>Cortical activity in the frontal, central and parietal cortex regions with focus on the following specific frequencies:<br>- theta (4.75-6.75 Hz)<br>- Alpha-1 (7-9.5 Hz)<br>- Alpha-2 (9.75-12.5 Hz).<br><br>Primary outcome during stair climbing (up/down):<br>Neuromuscular activity normalized for gait activity during angular reproduction divided into the gait phases:<br>- pre-activation<br>- weight acceptance <br>- push off.

Secondary Outcome Measures

Name	Time	Method
Deviation between the target angle and executed angle and movement duration during the angle reproduction test.<br>Jumping distance in meter during the one-leg jumps.
