In this paper, the purpose is to make Muscle-Skeletal Kinematic Model of Index Finger and measure the force vector of muscle. The finger from a posture where it has extended to a posture where joints have been flexed completely is divided in posture of6 patterns. The finger was taken an image with MRI in each posture. With AutoCAD the 3D model of the finger were constructed in three subjects. In calculating the joint center, the basipodite bone of other posture was superposed to the basipodite bone of a certain posture which was standard. The moment arm of the tendon and muscle was measured by obtained joint center. The force vector of muscle is obtained by using those parameters. The results show that TE, LUM, INTP, INTD puts out power in the direction of extension and FDS, FDP puts out power in the direction offlection.
