Coordination and symmetry patterns during the drop vertical jump, 6-months after first-time lateral ankle sprain

ABSTRACT To evaluate the adaptive movement and motor control patterns of a group with a 6‐month history of first‐time lateral ankle sprain (LAS) injury during a drop vertical jump (DVJ) task. Fifty‐one participants with a 6‐month history of first‐time acute LAS injury and twenty controls performed a...

Summary:ABSTRACT To evaluate the adaptive movement and motor control patterns of a group with a 6‐month history of first‐time lateral ankle sprain (LAS) injury during a drop vertical jump (DVJ) task. Fifty‐one participants with a 6‐month history of first‐time acute LAS injury and twenty controls performed a DVJ task. 3D kinematic and sagittal plane kinetic profiles were plotted for the lower extremity joints of both limbs for the drop jump (phase 1) and drop landing (phase 2) phases of the DVJ. Inter‐limb symmetry and the rate of impact modulation (RIM) relative to bodyweight (BW) during both phases of the DVJ were also determined. LAS participants displayed bilateral increases in knee flexion and an increase in ankle inversion during phases 1 and 2, respectively. They also displayed reduced ankle plantar flexion on their injured limb during both phases of the DVJ (p
