Participants completed five trials of maximal jump landing\/cutting. Lower extremity joint angles and EMG activation of seven muscles were collected from initial contact to toe\u2010off. Functional analyses of variance were used to evaluate between\u2010group differences for these outcome variables.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Hypo\u2010DFROM group (14M, 10F) displayed the reduced ankle dorsiflexion and inversion angles with increased hip flexion angle as a compensatory kinematic chain movement strategy. In addition, motion restrictions of the ankle are associated with altered muscle activation in both distal and proximal muscles during landing\/cutting. Normal\u2010DFROM (25M, 30F) and Hyper\u2010DFROM (11M, 10F) groups also have different movement strategies including greater inversion angle and less EMG activation, which could contribute to further ankle injuries.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Our data suggest that limited DFROM negatively affects the ankle joint during demanding movement within the CAI population.
