    <jats:p>Return to sport decision-making may be improved by assessing an athlete’s
    ability to coordinate movement with opponents in sport. The purpose was to investigate
    whether previous injuries associated with female soccer players’ interpersonal
    coordination during a collision avoidance task. The authors hypothesized that
    external perturbations would disrupt the strength and stability of coordinated
    movement, and that individuals with a history of injury would be less likely to
    recover coordinated movement.</jats:p> </jats:sec> <jats:sec id="study-design">

    <jats:sec id="methods"> <jats:title>Methods</jats:title> <jats:p>Nine female athletes
    with a history of lower extremity injuries and nine without injuries were paired
    into dyads. Each dyad completed twenty trials of an externally paced collision-avoidance
    agility task with an unanticipated perturbation. Participant trajectories were
    digitized and analyzed using cross-recurrence quantification analysis (CRQA) to
    determine the strength and stability of interpersonal coordination dynamics. Trials
    in which participants with injury history assumed leader or follower roles within
    each dyad were then used to study how dyadic coordination varied across task stages
    (early, perturbation, and late) using linear mixed effect models. Cohen’s d effect
    sizes were calculated to demonstrate magnitude of differences. In exploratory
    analysis, psychological readiness (i.e., self-reported knee functioning, fear
    of injury, and risk-taking propensity) was evaluated for their association with
    leader-follower status.</jats:p> </jats:sec> <jats:sec id="results"> <jats:title>Results</jats:title>
    <jats:p>Perturbation disrupted the strength (R2=0.65, p&lt;0.001, early=49.7±1.7,
    perturbation=41.1±1.7, d=0.39) and stability (R2=0.71, p &lt; 0.001, early=65.0±1.6,
    perturbation=58.0±1.7, d=0.38) of interpersonal coordination regardless of leader-follower
    status. Individuals with injury history failed to restore coordination after the
    perturbation compared to control participants (injury=44.2.0±2.1, control=50.8±2.6,
    d=0.39). Neither demographic nor psychological measures were associated with leader-follower
    roles (B=0.039, p=0.224).</jats:p> </jats:sec> <jats:sec id="conclusion"> <jats:title>Conclusion</jats:title>
    <jats:p>Individuals with a history of lower extremity injury may have a diminished
    ability to adapt interpersonal coordination to perturbations, possibly contributing

    basketball, changing direction is one of the primary mechanisms of anterior cruciate
    ligament (ACL) injury, often occurring within complex game situations with high

    <jats:p>The purpose of this research was to study the effect of added cognitive
    load, in the form of increased visual attentional demands, on sidestep cutting

    environment.</jats:p> </jats:sec> <jats:sec id="study-design"> <jats:title>Study

    <jats:title>Methods</jats:title> <jats:p>Fifteen male basketball players (aged
    22.1 ± 2.3) performed ten sidestep cutting movements without (BASE) and with (VIS)
    a visual attention dual task. 3D kinematics of the hip, knee and ankle were recorded
    utilizing Xsens IMU motion capture. Temporal kinematics were analyzed using Statistical
    Parametric Mapping. Discrete time point kinematics were additionally analyzed

  text: <jats:p>Individuals after anterior cruciate ligament reconstruction (ACLR)
    have a high rate of reinjury upon return to competitive sports. Deficits in motor
    control may influence reinjury risk and can be addressed during rehabilitation
    with motor learning strategies. When instructing patients in performing motor
    tasks after ACLR, an external focus of attention directed to the intended movement
    effect has been shown to be more effective in reducing reinjury risk than an internal
    focus of attention on body movements. While this concept is mostly agreed upon,
    recent literature has made it clear that the interpretation and implementation
    of an external focus of attention within ACLR rehabilitation needs to be better
    described. The purpose of this commentary is to provide a clinical framework for
    the application of attentional focus strategies and guide clinicians towards effectively
    utilizing an external focus of attention in rehabilitation after ACLR.</jats:p>
