**3. Result**

The general characteristics confirmed the homogeneity between the two groups (Table 1).


**Table 1.** General characteristics of the recruited subjects.

a Values are denoted as the mean ± SD. b Chi-square test among two intervention groups. c Independent *t*-test among two intervention groups. d GMFCS: Gross motor function classification system.

### *3.1. Change in ROM Dorsiflexion*

The experimental groups showed a significant increase in ankle ROM in the sitting and standing position. In addition, the experimental group displayed a significant increase in all ankle ROM compared to the control group (Table 2).


**Table 2.** Comparison in dorsiflexion ROM pre- and post-test.

a Values are the means ± SD. b Values are the 95% confidence intervals. \* Within-group factors: Significant increase compared to the pre-test. \*\* Between-group factors (Interaction): Significant increase compared to the control group. Experimental group: Ankle joint mobilization. Control group: Sham joint mobilization. ROM: Range of motion.

### *3.2. Change in COP Displacements, TUG, and 10-m Walk Test*

Both the experimental and the control groups displayed a significant decrease in the static sway length and area in the eyes opened condition, eyes closed condition, TUG, and 10-m walk (Table 3). In addition, the experimental group had a significantly increased TUG and 10-m walk test than the control group. However, there was no significant difference between the two groups. However, there was no significant difference between the experimental group and control group in COP displacements (Table 3).



a Values are the means ± SD. b Values are the 95% confidence intervals. \* Within-group factors: Significant decrease than the pre-test. \* Within-group factors: Significant decrease compared to the pre-test. \*\* Between-group factors (Interaction): Significant decrease compared to the control group. Experimental group: Ankle joint mobilization. Control group: Sham joint mobilization. TUG test: Timed up and go test. 10 MWT: 10-m walk test.
