A Basic Study of Auricular Movement for the Purpose of Controlling FES Systems

摘要

Functional Electrical Stimulation (FES) is an effective method for the restoration of paralyzed motor functions of the quadriplegics. FES systems require control commands. For the use of auricular movement as a control command in a FES system, I examined several methods to detect the movement. Of those methods, the one using a magnet and a search coil was the best against the influences of other actions. With this method, the number of repetition' of the movement and the time of the Period of the movement can be used as control signals. Since auricular movement can be used by almost all patients and also be used with other control commands, I expect the use of auricular movement will improve FES systems in the future.
