Short foot exercise is widely used as a therapeutic intervention for patients who have flat foot, but it is difficult to accurately educate and induce effective contraction for the flat foot patients with actual dysfunction of the foot internal muscle. This requires a more effective method that takes into account both aspects of accurate recognition of short foot exercise and large contractions of dysfunctional foot intrinsic muscle. Therefore, in this study, we divided into three groups based on whether or not short foot exercise was applied and how it was applied, and compared the medial longitudinal arch (MLA) angle, activity of the abductor hallucis (AbdH), and static balance.
Twenty-four adult men and women in their 20s with flexible flatfoot were recruited and eight were randomly assigned to three groups: control, experimental group A (Inclined short foot exercise group) and experimental groupB (Inclined short foot exercise with electromyography visual feedback group). The control group did not perform any exercise during the four weeks, the ISF group performed the short foot exercise three times a week with 30 degrees of ankle dorsiflexion, and the ISFB group performed the short foot exercise in the same condition as the ISF group with electromyography visual feedback device.
All three groups carried out pre-test and post-test of the MLA angle, activity of the AbdH, and static balance. A paired t-test was conducted for verification of changes before and after intervention in each group, and a one-way ANOVA was conducted for comparative analysis between the three groups.
As a result of this study, the control group without exercise was similar to four weeks ago in all of its dependent variables after four weeks. In the MLA angle, there was a significant improvement in ISFB group than ISF group, and ISF group than Control group (p<.05). Activity of the AbdH also showed a significant improvement in ISFB group than ISF group, and ISF group than Control group (p<.05). In the case of static balance, the ISFB group and ISF group showed significant improvement than the control group when the eyes were closed (p<.05), there was no difference between ISFB group and ISF group. With their eyes open, all three groups showed no significant improvement.
This study has demonstrated that the application of ankle dorsiflexion and electromyography visual feedback together during short foot exercise brings greater improvement to the MLA angle, activity of the AbdH, and static balance in visual blockage than when simply applying ankle dorsiflexion alone. Therefore, when training and applying short foot exercise to flat-footed patients in clinical and exercise centers, if the ankle dorsiflexion and electromyography visual feedback applies simultaneously, it is thought that short foot exercise can be performed more effectively.
