Objectives: This study observed changes in gait pattern according to the motor grade of the paretic lower limb in patients with basal ganglia stroke who are in the subacute phase.
Methods: We used the Manual Muscle Test (MMT) to evaluate the motor grade of the paretic lower limb of 21 patients with subacute basal ganglia stroke and then divided them into two groups based on the MMT results. Stroke patients with a motor grade above Gr. III were put in group I (15 people) and those with a grade less than Gr. III in group II (6 people). We also estimated spatiotemporal factors using treadmill gait analysis equipment. The values were gait velocity, step length, step time, double support phase, and cadence. The first measure was conducted during the early period of admission and the second was between four and five weeks after admission.
Results: In Group I, the gait velocity and step length of both legs significantly increased. In Group II, the step length and step time of the paretic side and the gait velocity tended to decrease, but not significantly. The step length of the paretic side in Group II was significantly longer than that in Group I at the first measure. The step time of the paretic side in Group I was significantly shorter than that in Group II and gait velocity and cadence in Group I were significantly higher than in Group II at the second measure.
Conclusions: The gait parameters of all stroke patients improved in terms of time. In addition, the changes in gait pattern were different depending on the motor grade of the paretic lower limb.
