In the complete paralysis class where the patients had motor palsy in their lower limbs (SIAS score of 0 points for the paralyzed lower limbs), the median FIMW score at admission was 1 point in both groups. In a study by Tanino et al.12), the authors reported that improving the FIMW score of 1 point at admission was difficult for patients with stroke in the convalescent rehabilitation ward. The median FIMW score at discharge was 2 points for patients that were paralyzed in both lower limbs. In our study, the improvements in FIMW score that were observed in the PT3unit group were equivalent to those reported in previous publications12), while the PT6unit group showed great improvements beginning at the 4th week of admission. This suggests that the increased amount of PT exercise contributed to improvements in the walking ability of patients with hemiplegic stroke. Patients with more severe disorders have a fear of falling, and they need assistance to maintain their postures. Therefore, the amount of exercise decreases13). Increases in the total amount of physical therapy exercise were assumed to result in sufficient time for ambulatory exercises, and this promoted motor learning.
