Phase delays for inter- and intralimb coordination. Phase delays are represented by proportion (0–1) of gait cycle out of phase. Phase values are calculated as lead (positive value) or lag (negative value) of the maximum flexion or touchdown for the second item with respect to the first item. Hip-Knee, hip to knee maximum flexion; Hip-Ankle, hip to ankle maximum flexion; Shoulder-Elbow, shoulder to elbow maximum flexion; RHL_LHL, right hindlimb to left hindlimb touchdown; RHL_RFL, right hindlimb to right forelimb touchdown; and LFL_RFL, left forelimb to right forelimb touchdown. Mean ± SEM for 5 rats per group. (*) indicates p<0.05 when compared with sham. Hindlimb-Forelimb (HL-FL) becomes completely out of phase. Decrease in Hip-Knee and Hip-Ankle delay: both become more in-phase with one another. No changes in forelimb (Shoulder-Elbow) or left-right phase delays (forelimb or hindlimb). Dashed gray line represents a phase relationship of 0.5 (completely out of phase).
