NCT03336060

Brief Summary

To examine the long-term effects of anterior cruciate ligament injuries and reconstructions (after successful rehabilitation) on cortical processes of motor planning during complex jump landing tasks and the relevance of cognitive performance measures for landing stability, respectively knee injury risk.

Outcome Measures

Primary Outcomes (3)

  • Bereitschaftspotential - Movement planning associated cortical activity measures

    Determined via Electroencephalography as amplitude in microvolt \[μV\] and latency in milliseconds \[ms\] before initiation of jump movement

    Cross sectional design. Time Frame for Assessment of Movement planning associated cortical activity measures (Bereitschaftspotential, low beta-band power, frontal theta-band power) is 4 hours on one day

  • Sensorimotor rhythm (SMR)/ low beta-band power - Movement planning associated cortical activity measures

    Determined via Electroencephalography in microvolt\^2 \[μV²\]

    Cross sectional design. Time Frame for Assessment of Movement planning associated cortical activity measures (Bereitschaftspotential, low beta-band power, frontal theta-band power) is 4 hours on one day

  • Frontal theta-band power - Movement planning associated cortical activity measures

    Determined via Electroencephalography in microvolt\^2 \[μV²\]

    Cross sectional design. Time Frame for Assessment of Movement planning associated cortical activity measures (Bereitschaftspotential, SMR/ low beta-band power, frontal theta-band power) is 4 hours on one day

Secondary Outcomes (19)

  • Peak ground reaction force - Biomechanical outcome measures of single leg jump-landings

    Cross sectional design. Biomechanical outcome measures of single leg jump-landings are assessed simultaneously with primary outcome assessment (during same 4 hours on one day)

  • Time to stabilisation - Biomechanical outcome measures of single leg jump-landings

    Cross sectional design. Biomechanical outcome measures of single leg jump-landings are assessed simultaneously with primary outcome assessment (during same 4 hours on one day)

  • Center of pressure sway - Biomechanical outcome measures of single leg jump-landings

    Cross sectional design. Biomechanical outcome measures of single leg jump-landings are assessed simultaneously with primary outcome assessment (during same 4 hours on one day)

  • Visual perceptual ability - Lower cognitive function

    Cross sectional design. Timeframe for Assessment is 5 minutes (during congnitive function assessment, separate day as primary outcome assessment)

  • Reaction time/ processing speed - Lower cognitive function

    Cross sectional design. Timeframe for Assessment is 10 minutes (during congnitive function assessment, separate day as primary outcome assessment)

  • +14 more secondary outcomes

Study Arms (2)

Healthy Control

Age matched healthy subjects. Inclusion criteria for healthy controls are: male (18 - 40 years, right-handed); sportive (preferably ball game sports, e.g. soccer); no acute injury or life-quality impairing diseases; no medication

Diagnostic Test: Cortical Correlates of Jump Landing Task

Subjects with ACL reconstruction

Unilateral, primary anterior cruciate ligament tear and reconstruction (1 to 10 years ago); no serious concomitant injuries, e.g. "unhappy triad"); no kinesiophobia; symmetric single leg jump performance (\>85 %); male (18 - 40 years, right-handed); sportive (preferably ball game sports, e.g. soccer); no acute injury or life-quality impairing diseases; no medication

Diagnostic Test: Cortical Correlates of Jump Landing Task

Interventions

The study participants perform counter-movement jumps (CMJ, flight time approximately 500 ms) followed by single leg landings. While under an anticipated condition, the individuals receive the visual information (presented on a screen) on which leg/ foot (left, right) they are required to land before self-initiated CMJs, the individuals will receive this information under the non-anticipated condition only after take-off (approximately 400 ms before ground contact).

Healthy ControlSubjects with ACL reconstruction
