[Purpose] The purpose of this study was to determine the effect of stepping limb and step
direction on step distance and the association of step distance and stepping laterality in
step difference with walking ability and motor dysfunction. [Subjects and Methods] The
subjects were thirty-nine patients with chronic hemiparesis as a result of stroke, who
performed the MSL (Maximum Step Length) test along with tests of motor impairment, gait
speed and Functional Ambulation Category. The MSL test is a clinical test of stepping
distance in which participants step to the front, side, and back. The subjects were
classified into three groups according to the stepping laterality in front step distance.
[Results] Step distance did not differ across stepping limbs but did differ across step
directions. Front step distance was significantly longer than side and back step distance.
Participants with forward paretic step length shorter than forward non-paretic step length
had significantly higher walking ability than participants with symmetric forward step
length or forward paretic step length longer than forward non-paretic step length
[Conclusion] Patients with stroke have characteristic step distances in each direction.
Adequate weight shift toward the paretic limb when stepping with the non-paretic limb is
associated with walking ability.
