| Summary: | The purpose of this work is to develop a 2D static biomechanical model of the index
finger as a general solution to estimate the tendon forces involved during free finger
flexion-extension and to limit the degree of statistical indeterminacy. The model had been
verified by means of three simulations: flexion-extension ofjoints, pinch grip and power grasp. The simulation also demonstrated the relevance of modelling passive forces generated by structures such as ligaments and soft tissues in order to accurately reproduce the force patterns of the finger seen during movement and static manipulative postures. In addition, the mathematical analysis of a forward dynamics biomechanical model based on Newton-Euler formulation had been proposed as an extension of this work into fast phalangeal movement. |
