Figure 3.

Joint kinematics of knee (1st row), hip (3rd row), ankle (5th row), and pelvis (7th row) collected on the field during change of direction in game. Data are clustered according to the knee moments emerged in the lab (Cluster 1, green, “low-risk”; Cluster 2, yellow, “mid-risk”; Cluster 3, red, “high-risk”). Data are presented as mean and standard deviation on the frontal (1st column), transverse (2nd column), and sagittal (3rd column) plane. One-way ANOVA through Statistical Parametric Mapping (SPM) was used to compare the groups (rows 2, 4, 6, 8 for knee, hip, ankle, and pelvis, respectively). Data are normalized from 50 ms prior to foot initial contact to 25 ms after toe-off. Dotted lines represent initial contact and toe-off. Positive rotations: flexion (dorsiflexion, anteversion) on sagittal plane, abduction (abduction, inversion, ipsilateral tilt) on frontal plane, and internal rotation (ipsilateral rotation) on transverse plane.
