Conditions
Interventions
Participants are asked to walk a distance of 15 meters and perform three
different hoptests while wearing motionsensors and EMG sensors. During the
first hoptest, the participant may decide when he/

18 Years to 64 Years
Inclusion criteria
Inclusion criteria: To participate in this study, a participant of the ACLr group must meet the following criteria: - At the time of inclusion, an age between 18 and 30 years old - Primary ACLr, as evidenced by history and physical examination and additional examination (MRI); - Physiotherapy during rehabilitation after ACLr; - Between 6-24 months after ACLr. To participate in this study, a participant in the control group must meet the following criteria: - At the time of inclusion, an age of 18 to 30 years; - No knee injury that affects knee instability, such as ACL rupture; - No lower extremity injury in the 6 months prior to study entry, resulting in more than 2 weeks of inability to exercise; - No motor impairment at the time of the measurement.
Exclusion criteria
Exclusion criteria: A potential participant who meets any of the following criteria will be excluded from this study: - Color blindness - Visual impairment; - Neurological disabilities. A potential participant of the ACLr group who meets one of the following criteria will be excluded from participation in this study: - Complications during rehabilitation (re-rupture, additional knee damage and/or no functional recovery after 6 months); - Bilateral ACL rupture and/or revision ACLr; - Multiligamentary knee injury; - Swelling of the knee, defined as stroke > 2; - Degenerative changes in the knee joint; - Surgical procedures or injuries of the contralateral leg.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome is the difference in jump distance between a traditional hoptest and the hoptests with added neurocognitive load in 1) patients after ACLr and 2) individuals without knee injury. The jump distance between the traditional jump test, the first neurocognitive jump test and the second neurocognitive jump test is compared. | — |
Secondary
| Measure | Time frame |
|---|---|
| The first secundary outcome is the left-right difference in traditional jump tests and the left-right difference in jump tests with added neurcognitive load. Other secondary outcomes consist of parameters derived from muscle activity and joint angles, measured with EMG and 3D motion sensors, respectively. | — |
