Abstract

Purpose: This study aims to identify the differences in the muscle activity of the ankle joint muscle depending on the type of footwear (sneakers, mule sneakers, slippers) worn while walking on a slope.
Methods: The subjects wore each shoe (sneakers, mule sneakers, and slippers) and walked on an 18-degree slope at a speed of 110 beats/min. While walking, the muscle activities of the tibialis anterior and medial gastrocnemius were measured. Of the three walking cycles, the second walking cycle was measured except for the first and third walking cycles, which are the beginning and end, and a three-minute break was taken to prevent muscle fatigue when the type of footwear was changed.
Results: When walking on a slope, there was no significant difference in the muscle activity of the tibialis anterior according to the type of footwear. However, when walking on a slope, the difference in muscle medial gastrocnemius muscle activity was significant between sneakers and mule sneakers. There was also a significant difference between sneakers and slippers, but there was no significant difference between slippers and mule sneakers.
Conclusion: There was no significant statistical difference between sneakers and mule sneakers, but there was a numerical difference. Therefore, the presence or absence of the shoe collar may affect the muscle activity of the medial gastrocnemius when walking on a slope. This can lead to patellofemoral pain syndrome caused by the excessive use of the quadriceps, so it must be considered that caution is needed.
