本研究選用三種市面上販售的可撓曲鞋子，搭配三種不同走路和跑步的速度，觀察步態推蹬期掌趾關節彎曲角度以及下肢肌肉肌電活化情形。研究結果發現選定的shoe 3在三種速度下，掌趾關節彎曲角度都比其他兩雙大，腓腸肌的肌電活化只有在快走下比其他兩雙少。

The purpose of this article was to figure out the differences of metatarsophalangeal joint (MPJ) range of motion (ROM) and the activation of EMG of lower extremity among three kinds of flexible shoes while walking, jogging, and running. The result shows that while wearing shoe 3 the MPJ ROM is the greatest during walking, jogging, and running, and the activation of the EMG of lower extremity is the lowest only in walking, during the push-off phase of gait cycle.
