Effects of ankle exercises on balance ability when using shoe height insoles

[Purpose] The purpose of this study was to examine the effects of ankle exercises on balance ability when using shoe height insoles. [Subjects and Methods] Thirty adults in their 20s, who were students, were randomly divided into an experimental group and a control group (n=15/group). Individuals in the experimental group wore height-adjustable silicon insoles measuring 3, 5, and 7 cm three times per week for four weeks. The ankle exercise program consisted of stretching exercises, resistance training, and a balance exercise. [Results] There was a significant improvement in the balance ability of the experimental group for all height insoles (3, 5, and 7 cm) following the exercise program, as compared with before the exercise program. There was no significant improvement in the balance ability of the control group for all height insoles following the exercise program as compared with before the exercise program. The experimental group exhibited a significant improvement in balance ability following the exercise program for all the height insoles as compared with the control group. [Conclusion] According to the results of this study, active ankle exercises are helpful in preventing ankle joint damage, as they improve balance ability.
