The purpose of this study was to investigate how the movement strategies of lower limb joints were changed depending on the types of heel during sit-to-stand and stair gait. Twenty healthy females were participated in this study. All subjects performed sit-to-stand and stair gait three times each with three different types of heels - bare feet, 9 cm high-heeled shoes and unstable shoes. Trials were randomly ordered. Three dimensional motion analysis systems were used to collect and analyze the kinematic data of lower limb movements. The result of this study showed kinematic differences in pelvis, hip joints, knee joints and ankle joints while sit-to-stand and stair gait based on the types of heels. During the initial of sit-to-stand, hip joint flexion, knee joint flexion, ankle joint flexion and ankle joint inversion demonstrated significant differences. The maximal angles of hip joint flexion, hip joint adduction, knee joint flexion, ankle joint flexion and ankle joint inversion were significantly different while hip joint adduction, pelvic forward tilt, hip joint rotation, knee joint flexion, ankle joint flexion and ankle joint inversion made significant differences during the terminal of sit-to-stand. There were significant differences in pelvic forward tilt, pelvic rotation, hip joint flexion, hip joint adduction, hip joint rotation, knee joint flexion and ankle joint flexion during stair-ascent and, during stair-decent, pelvic forward tilt, hip joint flexion, hip joint adduction, hip joint rotation, knee joint flexion, ankle joint flexion, and ankle joint inversion made significant differences. Therefore, the types of heels played important roles in the selection of lower limb movements during sit-to-stand and stair gait which were essential parts of daily life movements.
