简要总结
Anterior cruciate ligament (ACL) injuries are common in sports and often require a long and challenging rehabilitation process. Athletes who sustain these injuries typically engage in pivoting and cutting sports, where these motor tasks must be performed simultaneously with cognitive tasks such as decision-making and keeping an eye on the opponent. Directing attention to both cognitive and motor tasks leads to cognitive-motor interference, which is associated with movement patterns that increase the risk of ACL (re)injury.
Therefore, it is crucial that before returning to such demanding sports after ACL reconstruction, athletes sufficiently develop and automate safe yet efficient motor skills to free up attentional capacity for decision-making, thereby reducing the risk of suboptimal movement patterns and reinjury.
However, current rehabilitation programs often primarily focus on the motor component in a single-task manner, giving insufficient attention to the cognitive component that is inseparable from sports.
This randomized controlled trial aims to investigate the effects of implementing motor-cognitive dual tasks in the end phase rehabilitation after ACL reconstruction on muscle function, functional outcomes, and patient-reported outcomes.

结局指标
主要结局
Voluntary quadriceps activation
时间窗: 5 months post ACL reconstruction (= prior to intervention); 7 months post ACL reconstruction (= after the intervention); 9 months post ACL reconstruction (= after a 2 month retention period)
A force-based isometric biodex measurement using the interpolated twitch/superimposed burst technique.
Patient reported knee function
时间窗: 5 months post ACL reconstruction (= prior to intervention); 7 months post ACL reconstruction (= after the intervention); 9 months post ACL reconstruction (= after a 2 month retention period)
Questioned using the Knee Injury and Osteoarthritis Outcome Score (KOOS) with its different subscores. Scores on the KOOS range from 0-100, with 0 representing the greatest possible problems in terms of knee function and 100 representing no problems.
Jumping height in hop tests
时间窗: 5 months post ACL reconstruction (= prior to intervention); 7 months post ACL reconstruction (= after the intervention); 9 months post ACL reconstruction (= after a 2 month retention period)
Performance in single hop tests and a single leg drop-jump expressed by jump height in centimeters.
Activity level
时间窗: 5 months post ACL reconstruction (= prior to intervention); 7 months post ACL reconstruction (= after the intervention); 9 months post ACL reconstruction (= after a 2 month retention period)
Questioned using the Tegner Score. The scores range from 0 to 10, with higher scores indicating higher activity levels.
Psychological readiness to return to sport
时间窗: 5 months post ACL reconstruction (= prior to intervention); 7 months post ACL reconstruction (= after the intervention); 9 months post ACL reconstruction (= after a 2 month retention period)
Questioned using the ACL-RSI. Scores range from 0 to 100. Higher scores indicate higher psychological readiness.
Quadriceps and hamstrings activity / cocontraction during hop tasks
时间窗: 5 months post ACL reconstruction (= prior to intervention); 7 months post ACL reconstruction (= after the intervention); 9 months post ACL reconstruction (= after a 2 month retention period)
Electromyographical measurement of quadriceps and hamstrings activation during hop tasks.
次要结局
- Quadriceps and hamstrings strength(5 months post ACL reconstruction (= prior to intervention); 7 months post ACL reconstruction (= after the intervention); 9 months post ACL reconstruction (= after a 2 month retention period))
- Kinesiophobia(5 months post ACL reconstruction (= prior to intervention); 7 months post ACL reconstruction (= after the intervention); 9 months post ACL reconstruction (= after a 2 month retention period))
- The amount of pain that the subjects experience.(5 months post ACL reconstruction (= prior to intervention); 7 months post ACL reconstruction (= after the intervention); 9 months post ACL reconstruction (= after a 2 month retention period))
- Subjective knee stability(5 months post ACL reconstruction (= prior to intervention); 7 months post ACL reconstruction (= after the intervention); 9 months post ACL reconstruction (= after a 2 month retention period))
