INTRODUCTION
Musculoskeletal foot pain is commonly found among community-dwelling older adults with a prevalence rate of approximately 20-37% [1, 2]. Higher prevalence of foot pain was found among the working population aged 50 and above [3-5]. The main risk factors included poor working posture, general shoe wear, abnormal foot type, and undistributed weight of plantar pressure relating to the weakness of foot and ankle muscles. In addition, toe flexor muscle weakness could reduce the control of body weight shifts during walking attributed to the slow speed of walking. The effect of slow walking speed increased plantar pressure especially in the toes, which affected both foot pain and the risk of falling [6, 7]. Consequently, foot pain can reduce the quality of life among older adults [5, 8].
