1. A method of controlling a prosthetic having a movement damper, comprising:
- measuring at least one characteristic of prosthetic movement;
calculating a damping value based at least partly on the at least one characteristic;
applying a filter, wherein the filter receives a calculated current, to filter the damping value based at least partly on input of values of previous damping values to the filter; and
applying the damping value to control resistance of a damper.
