A study on selective stimulation of nerve fibers using biphasic pulses

Biphasic selective stimulation is an effective electrical stimulation mode for preventing nerve fibers against electrochemical damage,' and for muscle's contracting smoothly, decreasing muscle's fatigue. By use of computer simulation, this paper presents three biphasic stimulation modes respectively using monopolar, bipolar and tripolar electrodes, which can selectively stimulating nerve fibers effectively. And the feasibility of these methods are verified by animal experiments on toad's sciatic nerve trunks in vitro. These methods will promote the clinical application of neuroelectrical stimulation.
