The purpose of this study is to develop a 3D kinematic model of the index finger for estimating the flexion and extension movements. High-resolution MRI scans were used in conjunction with CAD software to determine the three-dimensional moment arms for the muscles and tendons passing the interphalangeal and metacarpophalangeal joints of the index finger. The moment arms for each tendon or muscle were expressed with reference to the joint center. The results were presented at five or six different postures of the index finger. The results were presented for five or six different angles of joint flexion for a single tendon or muscle. The moment arms of tendons at the MP joint had results similar to those presented by An et al. or Fowler. Muscles at the MP joint had moment arms deviating from those presented by An et al. or Fowler.
