Black boxes indicate which forelimb or hindlimb has higher values. Green indicates decrease and red indicates increase of the values during heelwork walk compared to normal walk. Orange indicates increase of the values during heelwork walk compared to normal walk but not above 3% (normal).

FL, left forelimb; FR, right forelimb; HL, left hindlimb; HR, right hindlimb; PFz, peak vertical force; SI%, symmetry index; SD, standard deviation.
