Impact of prehensor stiffness on quality of haptic feedback in body-powered upper limb prostheses
The design goal of a prosthesis is to replicate or replace the lost functionality of the missing limb. However, currently available upper limb prosthetic devices generally fall short of this goal, and as a consequence are often abandoned or rejected by the users. Potentially contributing to this shortfall is the lack of stiffness modulation in commercial prostheses --- whereas intact individuals are able to adapt the stiffness properties of their limbs to the requirements of specific tasks, prosthesis users do not have this option. One particularly troubled area of prosthesis functionality is ...
