Directional properites of multijoint finger stiffness
Characterization of multijoint Finger stiffness: Dependence on finger posutre and force direction
The finger is controlled by two sets of muscles: the extrinsic muscles which exert primary forces and the intrrinsc muscles which serve coordinating and stabilizing functions. ialmost all of these muscles are bi- or triarticular.
