The experimental and control groups comprised 15 subjects each. However, one patient from the experimental group failed due to the aggravation of gout in the ankle joint, and a follow-up loss in the control group occurred due to a MERS coronavirus outbreak. Fourteen subjects in each group completed the clinical experiment. Table 1 shows the distribution of sex, age, average education, www.e-arm.org duration of stroke, and hemiplegic side in both groups. The demographics in the two groups did not show significant differences. The unaffected lateral FRT showed significantly higher results in the Biodex Balance System training group; whereas the rest of the tests showed no significant differences between the two groups ( Table 2) . Table 3 shows that the experimental group showed significant improvements in all tests-BBS (p=0.001), TUG (p=0.001), forward FRT (p=0.001), affected lateral FRT (p=0.001), and unaffected lateral FRT (p=0.002)-when the values before and after training were compared in each group. The control group also showed significant improvements in the same tests. However, the results for the 10mWT showed only significant improvements in the experimental group (11.38±3.0 to 10.12±2.47 seconds; p=0.01); whereas the control group did not show significant improvements. The improvement levels of the trunk strength (BPR score) for the experimental group using Spine Balance 3D system's evaluation program showed (Table 3 ). In addition, among the three conditions used in Biodex
