*3.2. The Results of Gait Parameter Analysis*

## 3.2.1. Step Count

The average step count during 40 m walk in right hemiparetic patients was 46.83 ± 13.89 steps and for the left hemiparetic patients was 38.44 ± 4.53 as shown in Table 9. The bilateral hemiparetic patients was 40.66 ± 16.77 and healthy adults was 31.29 ± 8.97, respectively.

## 3.2.2. Stride Time

The average stride time of the left foot in the right hemiparetic patients was 1.66 ± 0.20 s and that of the right foot was slowed to 1.77 ± 0.19 s as shown in Table 10. The average time difference between the two feet was 0.11 ± 0.04 s.


**Table 10.** Average stride time of right hemiparetic patients (*n* = 9) (unit: seconds).

The average stride time of left hemiparetic patients showed to be slowed to 1.75 ± 0.42 s on the left (affected) side and 1.64 ± 0.40 s on the right foot as shown in Table 11. The time difference between the two feet was 0.14 ± 0.04 s in average.


**Table 11.** Average stride time of left hemiparetic patients (*n* = 6) (unit: seconds).

The average stride time of the left foot in bilateral hemiparetic patients was 1.48 ± 0.06 s and that of the right foot was 1.52 ± 0.03, and the time difference between the two feet was 0.04 ± 0.04 as illustrated in Table 12.

**Table 12.** Average stride time of bilateral hemiparetic patients (*n* = 3) (unit: seconds).


Table 13 shows the average stride time of healthy adults and the time difference between the two feet. The stride time of the left foot was 1.34 ± 0.12 s and of the right was 1.35 ± 0.12 s. The average stride time difference between the two feet was 0.02 ± 0.03 s.


**Table 13.** Average stride time of healthy adults (*n* = 17) (unit: seconds).

The stride time CV of each group is presented in Table 14. The right hemiparetic patients had a CV of 13.33 ± 4.52% (left foot) and 23.88 ± 3.29% (right foot). The left hemiparetic patients had 20.83 ± 6.70%, 12.00 ± 3.34%, the bilateral hemiparetic patients had 19.33 ± 2.51% and 18.00 ± 1.73%, respectively. The healthy adults had 2.82 ± 1.91% and 2.47 ± 1.62%, respectively.

**Table 14.** Coefficient of Variation (CV) of stride time in each group (unit: %).


RH: right hemiparesis, LH: left hemiparesis, BH: bilateral hemiparesis, HA: healthy adults.

Figure 11 below shows the results of average stride time CV of each subject group. The CV of the left foot in left hemiparetic patient group was 22% and that of the right foot was 12%. The CV of the left foot in right hemiparetic patient group was 13% and that of the right foot was 24%. For bilateral hemiparetic patient group, the CV of the left foot was 19% and that of the right was 18%. The healthy group showed to have a CV of 2% on both sides of the foot.
