Application of Gate Arrays in Implants for Nerve Stimulation (Remobilization of Paraplegic Patients)

摘要: The aim of a research project founded in 1977 is to make paraplegic patients stand up and walk again by means functional electrostimulation (FES). This accomplished nerves innervating the muscles be activated. fundamental condition physiological function which characteristic most cases paraplegia. Compared heart pacemaker stimulation strategy, FES much more complicated because not one impulse, but full train impulses adequate amplitude, impulse duration, polarity, frequency necessary for movement cycle allow smooth well-controlled limbs. Beyond that, it must possible stimulate several or muscle groups individually as well simultaneously proper walking.
