| Summary: | 碩士 === 國立體育大學 === 運動保健學系碩士班 === 100 === The purpose of this study is to discuss the effect of a balance training program on the balance ability and planter pressure in patients with functional ankle instability. The study subjects were twenty male senior high school students with functional ankle instability. Ten of the volunteers, who were willing to receive balance training after school, were in the intervention group, while the others were in the control group. The intervention group received balance training aiming at BOSU(Both Sides Up) for five weeks－three times per week, and about twenty to thirty minutes each time. These students were mainly trained to open their eyes, close their eyes, stand with both legs and stand with single leg. On the other hand, the students in the control group maintained their regular exercise habits without any special training. Before and after the study all the twenty students were first given dynamic balance test-Star Excursion Balance Test(SEBT). After that, they received static balance test-single leg stance with eye closed and planter pressure was measured. At the same time, all the collected data were analyzed by using a independent test to compare both intervention and control groups in terms of balance performance and planter pressure distribution. The level of significance was set at α=.05. The result showed that the students’ performance at the dynamic balance test had no noticeable differences, but the intervention group made greater progress than the control one. And the static balance data showed significant differences after the test, and the students in the intervention group performed much better after the five-week balance training. However those in the control group had no obvious differences. As to the planter pressure, the data analysis showed no significant differences between the two groups before and after the test, but the intervention group’s planter pressure distribution had tendency to move inside. In conclusion, the five-week balance training program seemed to improves static balance performance significantly, and have a great effect on dynamic balance and planter pressure distribution. Therefore, it is recommended that the patients with functional ankle instability may as well receive long-term balance training program and follow-up. It is expected that the recurrence rate of ankle sprain will be lowered by the improvement of patients’ balance ability.
