Abstract

Background: In this study, the abductor hallucis activity and medial longitudinal arch angle were compared by performing four exercises, namely the short foot exercise, the short foot exercise with 2nd~5th toe extension, the short foot exercise with 2nd~5th toe extension with a load of 1kt on the sole, and the short foot exercise with 2nd~5th toe extension with a load of 2kg on the sole. Methods: Four short foot exercises as described above were performed by 20 healthy adult males and females. The abductor hallucis activity and medial longitudinal arch angle were measured and analyzed by surface electromyography and the Kinovea software program. Results: The short foot exercise with 2nd~5th toe extension, short foot exercise with 2nd~5th toe extension with a load of 1kg on the sole, and the short foot exercise with 2nd~5th toe extension with a load of 2kg on the sole showed significantly higher abductor hallucis activity than the short foot exercise alone. Among these, the short foot exercise with the 2nd~5th toe extension was the most effective. All exercises showed a significantly decreased medial longitudinal arch angle post-exercise than pre-exercise, and the short foot exercise with the 2nd~5th toe extension showed a significantly decreased medial longitudinal arch angle compared to the other three exercises. Conclusion: It is believed that the short foot exercise with the 2nd~5th toe extension can be proposed as an effective exercise that can replace the short foot exercise alone.
