The purpose of this research was to investigate if three different foot positions affected the knee joint forces during sit to stand. Subjects were 7 healthy adult volunteers. Sit-to-stand was performed in the following three foot positions: abduction, neutral and adduction. A motion analysis system and force plate were used to collect the data of knee joint forces. Knee joint forces during sit to stand was analyzed in either component of perpendicular, back and forth and lateral side. Result demonstrated that the knee joint forces was found to greater toward compression, anteriorly and medially in the beginning of the sit-to-stand. Also, in the adducted foot position, the knee joint forces toward the lateral side during the sit to stand showed a significantly lower value than the other two foot positions. In the beginning of the sit to stand at all foot positions, compression force and shear force of anteriorly and medially of the tibia became greater. After twenty percent of the sit to stand, knee joint forces became greater laterally, and by the adduction of the foot position, knee joint forces laterally was significantly lower. The different foot positions in the sit to stand affected the knee joint forces in the frontal plane.
