Abstract
[Purpose] This study examined the effects of 4-week of balance exercise with
medio-lateral unstable sole on ankle muscle activation and functional ability. [Subjects
and Methods] Thirty university students without current or past ankle injuries were
assigned to either an experimental group or control group. The experimental group
participated in a balance exercise program 3 times a week over 4 weeks, which consisted of
one-leg stands and semi-squat exercises with medio-lateral unstable sole. The control
group continued with their regular life activities without participation in the program.
Electromyographic activities of peroneus longus and brevis muscles were recorded during
stair descending immediately before and after the exercise program. Functional balance was
tested with the Star Excursion Balance test immediately before and after the exercise
program. Paired t-tests were used to assess statistical significance. [Results] Activation
of peroneus longus and brevis and Star Excursion Balance Test scores in both groups did
not show a significant difference between pre- and post-exercise. [Conclusion] A future
study is suggested with increased level of medio-lateral perturbation during outcome
measurements and exercises with addition of supervision in the exercise training and home
program.
